# Design Systems
Each subfolder is a portable design system in [`DESIGN.md`](../docs/spec.md)
format. Pick one in the top-bar **Design system** dropdown and every skill
will read it as part of its system prompt.
## What's bundled
- **`default/`** — Neutral Modern. Hand-authored starter for the OD spec.
- **`warm-editorial/`** — Warm Editorial. Hand-authored serif starter.
- **`atelier-zero/`** — Atelier Zero. Hand-authored magazine-grade
collage system: warm paper canvas, plaster-and-architecture imagery,
oversized italic-mixed display type, Roman-numeral section markers,
side rails of rotated micro-text, coordinate annotations, single
coral accent. Pairs with [`skills/open-design-landing/`](../skills/open-design-landing/)
and [`skills/open-design-landing-deck/`](../skills/open-design-landing-deck/)
for the canonical landing-page and slide-deck renderings.
- **`kami/`** — 紙 / 纸. Editorial paper system distilled from
[`tw93/kami`](https://github.com/tw93/kami) (MIT). Warm parchment canvas,
ink-blue accent, serif at one weight, no italic, no cool grays. Pairs with
the [`templates/kami-deck.html`](../templates/kami-deck.html) starter for
slide work.
- **57 design skills**, sourced from
[`bergside/awesome-design-skills`](https://github.com/bergside/awesome-design-skills)
and added directly as normalized 9-section `DESIGN.md` files.
- **70 product systems**, imported from
[`VoltAgent/awesome-design-md`](https://github.com/VoltAgent/awesome-design-md)
(the [`getdesign@latest`](https://www.npmjs.com/package/getdesign) npm
package, MIT-licensed). One folder per brand:
| Category | Systems |
|---|---|
| AI & LLM | claude · cohere · elevenlabs · minimax · mistral-ai · ollama · opencode-ai · replicate · runwayml · together-ai · voltagent · x-ai |
| Developer Tools | cursor · expo · lovable · raycast · superhuman · vercel · warp |
| Productivity & SaaS | cal · intercom · linear-app · mintlify · notion · resend · zapier |
| Backend & Data | clickhouse · composio · hashicorp · mongodb · posthog · sanity · sentry · supabase |
| Design & Creative | airtable · clay · figma · framer · miro · webflow |
| Fintech & Crypto | binance · coinbase · kraken · mastercard · revolut · stripe · wise |
| E-Commerce & Retail | airbnb · meta · nike · shopify · starbucks |
| Media & Consumer | apple · ibm · nvidia · pinterest · playstation · spacex · spotify · theverge · uber · vodafone · wired · xiaohongshu |
| Automotive | bmw · bugatti · ferrari · lamborghini · renault · tesla |
Folders use ASCII slugs — dotted brands are normalized (`linear.app` →
`linear-app`, `x.ai` → `x-ai`, etc.).
## File shape
The first H1 is the title shown in the picker. The line immediately after
the H1 is parsed for `> Category: <name>` and used to group the dropdown:
```markdown
# Design System Inspired by Cohere
> Category: AI & LLM
> Enterprise AI platform. Vibrant gradients, data-rich dashboard aesthetic.
## 1. Visual Theme & Atmosphere
...
```
Both the boilerplate prefix `Design System Inspired by ` and the
`> Category: ...` line are stripped from the dropdown label and the summary
preview at runtime — they're only metadata.
## Adding your own
Drop a new folder containing a `DESIGN.md` and it shows up on next refresh.
Add a `> Category: <Group>` line to slot it under an existing group, or use
any new label and it lands at the bottom of the dropdown.
## Refreshing the bundled set
The 70 product systems are pulled from the upstream npm package. To re-sync
to the latest hashes:
```bash
curl -sL $(npm view getdesign dist.tarball) -o /tmp/getdesign.tgz
tar -xzf /tmp/getdesign.tgz -C /tmp
node --experimental-strip-types scripts/sync-design-systems.ts
```
For now, the original importer lives at the top of the
[`excessive-climb` branch](../) — re-run it against a fresh tarball.

# Design System Inspired by Agentic
> Category: Themed & Unique
> Conversational AI-first interface with minimal controls, clear outcomes, and delegated task flows for agentic workflows.
## 1. Visual Theme & Atmosphere
Conversational AI-first interface with minimal controls, clear outcomes, and delegated task flows for agentic workflows.
- **Visual style:** modern, bold
- **Color stance:** surface/subtle layers
- **Design intent:** Keep outputs recognizable to this style family while preserving usability and readability.
## 2. Color
- **Primary:** `#FF5701` — Token from style foundations.
- **Secondary:** `#F6F6F1` — Token from style foundations.
- **Success:** `#16A34A` — Token from style foundations.
- **Warning:** `#D97706` — Token from style foundations.
- **Danger:** `#DC2626` — Token from style foundations.
- **Surface:** `#FFFFFF` — Token from style foundations.
- **Text:** `#111827` — Token from style foundations.
- **Neutral:** `#FFFFFF` — Derived from the surface token for official format compatibility.
- Favor Primary (#FF5701) for CTA emphasis.
- Use Surface (#FFFFFF) for large backgrounds and cards.
- Keep body copy on Text (#111827) for legibility.
## 3. Typography
- **Scale:** 14/16/18/24/32/40
- **Families:** primary=Playfair Display, display=Playfair Display, mono=JetBrains Mono
- **Weights:** 100, 200, 300, 400, 500, 600, 700, 800, 900
- Headings should carry the style personality; body text should optimize scanability and contrast.
## 4. Spacing & Grid
- **Spacing scale:** 8pt baseline grid
- Keep vertical rhythm consistent across sections and components.
- Align columns and modules to a predictable grid; avoid ad-hoc offsets.
## 5. Layout & Composition
- Prefer clear content blocks with consistent internal padding.
- Keep hierarchy obvious: headline → support text → primary action.
- Use whitespace to separate concerns before adding borders or shadows.
## 6. Components
- Buttons: primary action uses `#FF5701`; secondary actions stay neutral.
- Inputs: strong focus-visible states, clear labels, and predictable error messaging.
- Cards/sections: use consistent radii, spacing, and elevation strategy across the page.
## 7. Motion & Interaction
- Use subtle transitions that emphasize Primary (#FF5701) as the interaction signal.
- Default to short, purposeful transitions (150–250ms) with stable easing.
- Ensure hover, focus-visible, active, disabled, and loading states are explicit.
## 8. Voice & Brand
- Tone should reflect the visual style: concise, confident, and product-specific.
- Keep microcopy action-oriented and avoid generic filler language.
- Preserve the style identity in headlines while keeping UI labels literal and clear.
## 9. Anti-patterns
- Do not introduce off-palette colors when an existing token can solve the problem.
- Do not flatten hierarchy by using the same type size/weight for all text.
- Do not add decorative effects that reduce readability or accessibility.
- Do not mix unrelated visual metaphors in the same interface.

# Design System Inspired by Airbnb
> Category: E-Commerce & Retail
> Travel marketplace. Warm coral accent, photography-driven, rounded UI.
## 1. Visual Theme & Atmosphere
Airbnb's 2026 design feels like a travel magazine that happens to be an app — pristine white canvases give way to full-bleed photography, and the interface itself disappears so the listings can breathe. The signature Rausch coral-pink (`#ff385c`) is used sparingly but unmistakably: search CTA, active tab indicator, primary action button, the occasional price or wishlist heart. Everything else is a disciplined grayscale, with `#222222` carrying almost every line of text.
What makes the system unmistakably Airbnb is how much *faith* it places in content. Property photos are displayed at hero scale, 4:3 with edge-to-edge radius treatment. Category switching happens through a tri-tab picker (Homes / Experiences / Services) that uses 3D rendered illustrated icons (a pitched-roof house, a hot-air balloon, a service bell) — physical, tactile, almost toy-like — paired with crisp `Airbnb Cereal VF` labels. This is the rare consumer product where 3D renders and purely typographic UI coexist without tension.
The newest surface is the **Experiences** product line — same chrome, but richer card density, more photography, and a center-anchored booking panel with sticky right-rail pricing. Listing detail pages (both rooms and experiences) follow a tight template: full-bleed hero image grid → overlapping rounded booking card (sticky on scroll) → amenities → reviews (Guest Favorite awards use a big centered `4.81` rating with a laurel-wreath lockup) → map → host profile → disclosures. The rhythm is consistent whether you're booking a room or a yacht tour.
**Key Characteristics:**
- Rausch coral-pink (`#ff385c`) as a single-accent brand color, used only for primary CTAs and the search button
- Full-bleed photography at 4:3 / 16:9 with gentle corner rounding (14–20px) as the primary visual vocabulary
- 3D rendered category icons paired with typographic tabs — the one place the system allows illustration
- Circular `50%` icon buttons (back arrow, share, favorite, carousel arrows) scattered throughout
- `Airbnb Cereal VF` carries every label, from 8px legal footnote to 28px section heading — a single-family system
- Product-tier color coding: Airbnb Plus (magenta `#92174d`), Airbnb Luxe (deep purple `#460479`), Airbnb (Rausch coral)
- Guest Favorite award lockup — centered giant rating number between two laurel wreaths, one of the most recognizable moments in the system
- Sticky booking panel with a price → dates → guests stack, pinned to the right rail on desktop, transforming to a bottom-anchored "Reserve" bar on mobile
- Sticky bottom mobile navigation (Explore / Wishlists / Log in) with an active-state Rausch tint
## 2. Color Palette & Roles
### Primary
- **Rausch** (`#ff385c`): The brand's signature coral-pink. CSS variable `--palette-bg-primary-core`. Used for: primary "Reserve" button, search submit button, active tab underline, wishlist heart fill, pricing emphasis. The single highest-visibility color on every page.
### Secondary & Accent
- **Deep Rausch** (`#e00b41`): A more saturated variant. CSS variable `--palette-bg-tertiary-core`. Used for pressed/active button states and gradient terminal stops.
- **Plus Magenta** (`#92174d`): CSS variable `--palette-bg-primary-plus`. The brand color for the Airbnb Plus product tier — a higher-end curated-listing offering.
- **Luxe Purple** (`#460479`): CSS variable `--palette-bg-primary-luxe`. The brand color for the Airbnb Luxe product tier — villa/estate-level rentals.
- **Info Blue** (`#428bff`): CSS variable `--palette-text-legal`. Used for legal/informational links (terms, privacy, disclosures) — the only non-monochrome link color in the system.
### Surface & Background
- **Canvas White** (`#ffffff`): The default page background. Every card, every container, every detail page starts here.
- **Soft Cloud** (`#f7f7f7`): Subtle subsurface tint used on footer backgrounds, map-view wrappers, and "everything else" sections that want to step back from the primary white.
- **Hairline Gray** (`#dddddd`): Ubiquitous 1px border color — separates cards, amenity rows, review panels, footer columns. The workhorse of the layout system.
### Neutrals & Text
- **Ink Black** (`#222222`): CSS variable `--palette-text-primary`. The system's near-black. Every heading, every body paragraph, every nav label, every price. Used for ~90% of all text on a page.
- **Charcoal** (`#3f3f3f`): CSS variable `--palette-text-focused`. Used in focused-state input text and one-step-down emphasis copy.
- **Ash Gray** (`#6a6a6a`): CSS variable `--palette-bg-tertiary-hover`. Secondary labels, "Cottage rentals" subtitle-style copy under city names, muted footer links.
- **Mute Gray** (`#929292`): CSS variable `--palette-text-link-disabled`. Disabled buttons and low-priority metadata.
- **Stone Gray** (`#c1c1c1`): Tertiary dividers, icon strokes, placeholder avatars.
### Semantic & Accent
- **Error Red** (`#c13515`): CSS variable `--palette-text-primary-error`. Form validation errors, destructive-action warnings.
- **Deep Error** (`#b32505`): CSS variable `--palette-text-secondary-error-hover`. Pressed/active variants of error states.
- **Translucent Black** (`rgba(0, 0, 0, 0.24)`): CSS variable `--palette-text-material-disabled`. Disabled material-style labels.
### Gradient System
Airbnb's brand gradient appears sparingly, typically only on the wordmark and the search-button branded moment:
```
linear-gradient(90deg, #ff385c 0%, #e00b41 50%, #92174d 100%)
```
This coral → magenta sweep is the "branded moment" — never used as a full surface, only as a narrow pill fill or logo treatment.
## 3. Typography Rules
### Font Family
- **Airbnb Cereal VF** (primary and only): The proprietary variable-weight sans-serif that carries the entire system. Fallbacks (in order): `Circular, -apple-system, system-ui, Roboto, Helvetica Neue, sans-serif`.
Weights observed in the extracted tokens: 500, 600, 700. No 400-regular — the system's "body" weight is 500, which gives every block of text a subtle extra density that reads as confident and deliberate.
OpenType features: `salt` (stylistic alternates) is used on the compact 11px and 14px 600-weight labels — likely for tighter numerals and special-character shaping. No ligature or fractional-numeral features observed.
### Hierarchy
| Role | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|--------|-------------|----------------|-------|
| Section Heading | 28px / 1.75rem | 700 | 1.43 | 0 | "Inspiration for future getaways" — page-level headings |
| Subsection Heading | 22px / 1.38rem | 500 | 1.18 | -0.44px | "What this place offers", "Meet the hosts" — content dividers |
| Card Title | 21px / 1.31rem | 700 | 1.43 | 0 | Review panel headings, card lead titles |
| Listing Title | 20px / 1.25rem | 600 | 1.20 | -0.18px | "Small Group Yacht Tour, Unlimited Wine & Fruits" — listing headlines on detail pages |
| Subtitle Bold | 16px / 1.00rem | 600 | 1.25 | 0 | Host name, city name |
| Body Medium | 16px / 1.00rem | 500 | 1.25 | 0 | Primary body copy on detail pages |
| Button Large | 16px / 1.00rem | 500 | 1.25 | 0 | "Reserve", "Become a host" |
| Button Default | 14px / 0.88rem | 500 | 1.29 | 0 | Standard button labels |
| Link | 14px / 0.88rem | 500 | 1.43 | 0 | Nav links, footer links |
| Caption Medium | 14px / 0.88rem | 500 | 1.29 | 0 | Metadata, subtitle lines ("Cottage rentals", "Villa rentals") |
| Caption Bold | 14px / 0.88rem | 600 | 1.43 | 0 | `salt` feature enabled — numeric stats, small-text emphasis |
| Caption Small | 13px / 0.81rem | 400 | 1.23 | 0 | Review dates, micro-metadata |
| Micro Default | 12px / 0.75rem | 400 | 1.33 | 0 | Footer disclaimers, legal micro-copy |
| Micro Bold | 12px / 0.75rem | 700 | 1.33 | 0 | "NEW" pill labels |
| Badge Uppercase | 11px / 0.69rem | 600 | 1.18 | 0 | `salt` feature — compact category/status badges |
| Superscript | 8px / 0.50rem | 700 | 1.25 | 0.32px | Uppercase — price footnotes, decimal tails |
### Principles
- **One family, many weights.** Airbnb Cereal VF handles everything from 8px legal to 28px page headings — the visual identity comes from the family itself, not from typeface mixing.
- **500 is the new 400.** The system's "regular" weight is 500, giving every paragraph a slightly more confident texture than the web default.
- **Negative tracking on display type only.** Headings 20px+ compress tracking by -0.18 to -0.44px to feel chiseled; body sizes stay at 0 tracking for readability.
- **Tight line-heights for headlines, generous for body.** Display type runs at 1.18–1.25 (tight); body and caption open up to 1.43 for long-form comfort.
- **No all-caps except at 8px.** The only uppercase transform in the system is the 8px superscript — everywhere else, sentence case with subtle weight shifts does the work.
### Note on Font Substitutes
Airbnb Cereal VF is proprietary. The closest open-source substitute is **Circular Std** (still commercial) or **Inter** (free, Google Fonts) with letter-spacing reduced by -0.01em at display sizes. For strict brand fidelity, the documented fallback chain (`Circular, -apple-system, system-ui`) renders acceptably on macOS/iOS where `system-ui` resolves to San Francisco, which has similar proportions.
## 4. Component Stylings

- Left: Airbnb wordmark+logo lockup in Rausch (102×32px)
- Center: tri-tab category picker (Homes / Experiences / Services) with 36–48px 3D icons stacked above 16px 500 labels; active tab has a 2px Ink Black underline
- Right: "Become a host" text link, then 32px circular globe (language), then 36px hamburger avatar menu
- Border-bottom: 1px solid Hairline Gray `#dddddd`
**Top Nav (Mobile)**
- Single-row search pill occupies full width: "Start your search" placeholder with a small magnifier icon
- Below: tri-tab category picker persists (Homes / Experiences / Services) — illustrated icons shrink to ~28px
- Bottom-fixed tab bar: Explore (active state Rausch) / Wishlists / Log in — 24px icons above 12px labels
**Listing Detail Secondary Nav**
- Sticky horizontal scroll of anchor links (Photos · Amenities · Reviews · Location · Host) appears on scroll past the hero image
- Height: 56px

- **Radius**: 14px on listing-grid images, 20px on detail-page hero photo frames, `50%` on avatars
- **Image grid on detail pages**: five-photo grid with a single large-left image (50% width) and four smaller photos in a 2×2 grid on the right, all sharing the 20px outer rounded container
- **Lazy loading**: heavy use of `loading="lazy"` with blurred placeholder previews
- **Carousel**: circular 32px arrow buttons overlay the image, centered vertically; dot indicators sit 12px above the bottom edge
### Signature Components
**Guest Favorite Award Lockup** (featured prominently on high-rated listing detail pages)
- Centered rating number rendered at 44–56px 700-weight
- Two hand-drawn laurel-wreath SVG illustrations flanking left and right at ~48px tall
- Below: "Guest Favorite" label at 12px 700 uppercase with `0.32px` tracking, and a short sub-label at 14px 500 Ash Gray
- Full-width block, no container border — sits directly on white canvas
**Tri-Tab Category Picker** (appears at the top of every browse surface)
- Three tabs: Homes / Experiences / Services
- Each tab: 3D-rendered illustrated icon (~48px tall) above 16px 500 label
- Experiences and Services currently carry a small navy-blue "NEW" pill (12px 700 white text on dark blue) floating top-right of the icon
- Active tab: 2px Ink Black underline beneath the label
**Inspiration City Grid** (homepage "Inspiration for future getaways")
- 6-column grid of destination links on desktop, 2-column on mobile
- Each cell: 16px 600 city name on line 1, 14px 500 Ash Gray rental-type subtitle on line 2 ("Cottage rentals", "Villa rentals")
- No images — text-only grid
- Tabbed above by category (Popular / Arts & culture / Beach / Mountains / Outdoors / Things to do / Travel tips & inspiration / Airbnb-friendly apartments) — active tab has 2px underline and weight shift
**Reserve Sticky Card** (listing detail pages)
- Stays fixed 120px below viewport top on desktop as the user scrolls past the hero
- Collapses to a full-width bottom bar on mobile with a "From $X / night" label and a Rausch "Reserve" pill
- Always shows: price headline → date display → guest selector → Rausch CTA → "You won't be charged yet" disclaimer
**Experience Host Card** (experience detail pages)
- Full-width rounded container with a 3:2 cover photograph at top
- Host avatar (circular, 56px) overlapping the bottom edge of the cover by 50%
- Below overlap: host name at 16px 700, host tenure at 14px 500 Ash Gray, small Rausch "Message host" pill button
- Used as the transition between reviews and the amenities/location block
**"Things to know" Strip** (listing detail pages)
- 3-column grid of rule/policy blocks (House rules, Safety & property, Cancellation policy)
- Each column: icon at the top, 16px 600 heading, 14px 500 Ash Gray body, "Show more" link in Ink Black underline
- Separator: 1px Hairline Gray top and bottom borders on the overall strip
## 5. Layout Principles
### Spacing System
- **Base unit**: 8px
- **Extracted scale**: 2, 3, 4, 5.5, 6, 8, 10, 11, 12, 15, 16, 18.5, 22, 24, 32px — fine-grained with a handful of off-grid values used for pixel-perfect icon alignment
- **Section padding**: ~48–64px top/bottom on desktop, 24–32px on mobile
- **Card internal padding**: 24px on booking panels and large cards, 16px on amenity rows, 12px on listing-card metadata
- **Gutter between listing cards**: 24px desktop, 16px mobile
- **Between stacked text rows**: 4–8px (very tight — reinforces the "dense information" feel of travel listings)
### Grid & Container
- **Max content width**: 1760–1920px on ultra-wide (Airbnb lets the grid breathe farther than most sites); 1280px on most detail pages
- **Homepage listing grid**: 6 columns at ≥1760px, 5 at ≥1440px, 4 at ≥1128px, 3 at ≥800px, 2 at ≥550px, 1 below
- **Detail page**: 2-column asymmetric — main content ~58%, sticky booking panel ~36% on the right, ~6% gutter
- **Footer**: 3-column Support / Hosting / Airbnb
### Whitespace Philosophy
Airbnb is densely informative but never cramped. Whitespace is used to *group* — listing cards have 24px of gutter so each photograph reads as a distinct object, but the metadata under each card uses 4–8px gaps so the price/city/date feels like a single unit. The detail-page booking panel has 24px internal padding, but rows within (date picker, guest selector, CTA) are stacked at 12px — the boundary between the card and the page does more separation work than the content within.
### Border Radius Scale
| Radius | Use |
|--------|-----|
| 4px | Inline anchor tags, tag chips |
| 8px | Text buttons, dropdowns, small utility buttons |
| 14px | Listing card photography, generic content containers, badges |
| 20px | Primary rounded buttons (pill shape), large images, booking panel |
| 32px | Search bar pill, extra-large containers |
| 50% | All circular icon buttons, all avatars, wishlist hearts — the system's signature round geometry |
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| 0 | No shadow | Listing cards, body content, text-only sections |
| 1 | `rgba(0, 0, 0, 0.08) 0 4px 12px` | Active/pressed icon buttons (e.g., back, share, favorite) — subtle lift to indicate interaction |
| 2 | `rgba(0, 0, 0, 0.02) 0 0 0 1px, rgba(0, 0, 0, 0.04) 0 2px 6px 0, rgba(0, 0, 0, 0.1) 0 4px 8px 0` | Booking panel sticky card, modals, dropdown menus — the system's signature three-layer elevation |
| Focus Ring | `0 0 0 2px #222222` | Active-state buttons, focused search input |
| White Separator Ring | `rgb(255, 255, 255) 0 0 0 4px` | Circular buttons overlaid on photographs — a 4px white ring cleanly separates the button from colorful image backgrounds |
Shadow philosophy: Airbnb uses **stacked layered shadows** rather than a single drop. The three-layer booking-panel shadow reads as one cohesive lift but is actually three separate shadows at different opacity/blur values — creating subtle anti-aliasing at the shadow's perimeter that feels premium without being heavy.
### Decorative Depth
- **Photography as depth**: the system relies heavily on full-bleed photography to create visual depth; shadows and gradients are used sparingly so the photographs do the heavy lifting
- **Laurel wreath lockup**: the Guest Favorite award uses two SVG laurel illustrations that give the otherwise-flat rating number a ceremonial, trophy-like presence
- **3D rendered category icons**: Homes/Experiences/Services icons have their own soft internal lighting and subtle cast shadows baked into the artwork — the only place the brand allows "dimensional" illustration
## 7. Do's and Don'ts
### Do
- Reserve Rausch `#ff385c` for primary actions and the active-tab indicator — never dilute it with decorative uses.
- Let photography breathe — 4:3 crops with 14–20px rounded corners, no overlaid text, no gradient scrims.
- Use Ink Black `#222222` for every text layer below Rausch — this is the system's near-black, never true `#000000`.
- Pair the tri-tab category picker's 3D illustrated icons with flat typography — don't mix illustration styles within a single surface.
- Stack three low-opacity shadows (~2%, 4%, 10%) to create the signature booking-panel elevation.
- Use Hairline Gray `#dddddd` 1px borders for every card-to-card and row-to-row divider.
- Treat the booking panel as sticky on desktop, collapsing to a bottom-anchored reserve bar on mobile.
- Use 4–8px spacing within metadata groups and 24px between cards — information density is intentional.
### Don't
- Don't introduce secondary accent colors outside the Rausch / Plus Magenta / Luxe Purple product-tier palette.
- Don't place text inside photographs — captions always sit below the image, never overlaid.
- Don't use all-caps labels except the single 8px superscript role.
- Don't round icon buttons to anything other than 50% — circular is the system's signature geometry.
- Don't add drop shadows to listing cards — they sit on white canvas with no elevation.
- Don't use gradient backgrounds — the only gradient in the system is a narrow Rausch → magenta sweep on the wordmark.
- Don't use the 400-regular font weight — Airbnb Cereal's body weight is 500.
- Don't override Airbnb Cereal VF with a different display face — the system is intentionally single-family.
## 8. Responsive Behavior
### Breakpoints
Airbnb declares ~60 breakpoints (design-time artifact from their component library), but the meaningful layout shifts happen at a much smaller set:
| Name | Width | Key Changes |
|------|-------|-------------|
| Ultra-wide | ≥1760px | 6-column listing grid, 1760–1920px max content width |
| Desktop XL | 1440–1759px | 5-column grid, full nav visible, sticky right-rail booking panel |
| Desktop | 1128–1439px | 4-column grid, sticky booking panel persists |
| Laptop | 1024–1127px | 3–4 column grid, category nav remains horizontal |
| Tablet | 800–1023px | 3-column grid, global search may collapse to a single-row pill |
| Small tablet | 550–799px | 2-column grid, booking panel drops to full-width inline block |
| Mobile | 375–549px | 1-column stacked layout, bottom-fixed tab bar appears (Explore / Wishlists / Log in) |
| Small mobile | <375px | Edge padding tightens to 16px; category-picker icons shrink to ~28px |
### Touch Targets
All interactive elements meet or exceed 44×44px. The circular icon button family is specifically sized 32–44px with 8–12px extended hit-area padding. The Rausch primary Reserve button is ~48px tall. The tri-tab category picker's hit area is the full label-plus-icon rectangle (typically ~64×80px per tab).
### Collapsing Strategy
- **Nav**: Top nav keeps Airbnb wordmark + tri-tab picker on tablet and above; on mobile the picker slides just below the search pill, and the globe/avatar controls move to a bottom-anchored tab bar.
- **Search bar**: Three-segment pill (Where / When / Who) with a Rausch circular submit button on desktop; collapses to a single-row "Start your search" pill on mobile, tapping which opens a full-screen search sheet.
- **Booking panel**: Sticky right-rail on ≥1128px; inline within the main content column between 800–1127px; bottom-fixed "Reserve" pill on <800px.
- **Listing grid**: Reflows 6 → 5 → 4 → 3 → 2 → 1 columns across breakpoints.
- **Detail-page image grid**: Five-image layout (1 large + 4 small) on desktop; becomes a swipeable full-bleed carousel on mobile with page-dot indicators.
- **Footer**: 3-column layout collapses to stacked single-column at <800px.
### Image Behavior
- `loading="lazy"` universal, with blurred `im_w=` URL-parameterized preview thumbs served first
- Responsive images use Airbnb's `muscache.com` CDN with `im_w` query parameter for width-based delivery (`im_w=240`, `im_w=720`, `im_w=1200`, `im_w=2400`)
- No art-direction crops — the same image is scaled up/down across breakpoints
- Carousels auto-advance photo height to maintain a consistent 4:3 ratio regardless of source aspect
## 9. Agent Prompt Guide
### Quick Color Reference
- Primary CTA: "Rausch (#ff385c)"
- Page background: "Canvas White (#ffffff)"
- Subsurface: "Soft Cloud (#f7f7f7)"
- Heading / body text: "Ink Black (#222222)"
- Secondary text: "Ash Gray (#6a6a6a)"
- Border / divider: "Hairline Gray (#dddddd)"
- Error: "Error Red (#c13515)"
- Info link: "Info Blue (#428bff)"
- Luxe tier accent: "Luxe Purple (#460479)"
- Plus tier accent: "Plus Magenta (#92174d)"
### Example Component Prompts
- "Create a primary Reserve button: Rausch (#ff385c) background, white Airbnb Cereal 500-weight label at 16px, 14px × 24px padding, 8px border-radius, no shadow. On active/pressed add `transform: scale(0.92)` with a 2px Ink Black focus ring (`0 0 0 2px #222222`)."
- "Build a listing card with a 4:3 full-bleed photograph at 14px border-radius, no container shadow; below the image stack three text rows with 4px gaps: city name at 16px 600 Ink Black, rental type at 14px 500 Ash Gray (#6a6a6a), and price range in 16px 500 Ink Black with a 14px `per night` suffix."
- "Design a sticky booking panel: white background, 14px border-radius, 1px Hairline Gray (#dddddd) border, 3-layer elevation shadow (`rgba(0,0,0,0.02) 0 0 0 1px, rgba(0,0,0,0.04) 0 2px 6px 0, rgba(0,0,0,0.1) 0 4px 8px 0`), 24px padding, 370px width, pinned 120px below viewport top on desktop. Contents: price headline, date picker, guest dropdown, Rausch primary CTA, and a 12px Ash Gray `You won't be charged yet` disclaimer."
- "Create a tri-tab category picker: three equal-width tabs labeled Homes, Experiences, Services; each tab has a ~48px 3D-rendered illustrated icon (house, balloon, bell) above a 16px 500 Ink Black label; active tab gets a 2px Ink Black underline; add a small 12px 700 white `NEW` pill on a dark navy background to the top-right of the Experiences and Services icons."
- "Render the Guest Favorite award lockup: a centered rating number at 52px 700-weight Ink Black, flanked left and right by hand-drawn SVG laurel wreaths at ~48px tall; below, a 12px 700 uppercase `GUEST FAVORITE` label with 0.32px tracking; sub-label at 14px 500 Ash Gray; full-width block sitting directly on white canvas with no container border."
### Iteration Guide
When refining existing screens generated with this design system:
1. Focus on ONE component at a time.
2. Reference specific color names and hex codes from this document (e.g., "Ink Black #222222", not "dark gray").
3. Use natural language descriptions alongside measurements ("subtle three-layer elevation" rather than a long shadow string).
4. Describe the desired "feel" ("magazine-like, photography-first" vs "dense utility").
5. Always default to Airbnb Cereal VF 500-weight for body and 600–700 for emphasis — never 400.
6. Keep Rausch pink scarce — if more than one Rausch-colored element appears per viewport, consider whether one should be neutralized.
### Known Gaps
- **Homepage listing grid cards**: the main property-card grid (the primary visual surface of airbnb.com) was not fully captured in the extracted homepage screenshots — content loaded only partially. Listing Card specs above are inferred from the Inspiration grid structure and Airbnb's broader conventions; confirm exact aspect ratios and metadata hierarchy against the live site before production use.
- **Experiences category icons**: the 3D illustrated icons for Homes / Experiences / Services are served as raster assets; their exact source-file specifications (SVG vs PNG, rendered pixel dimensions) are not documented here.
- **Animation and transition timings**: not captured — static extraction scope.
- **Dark mode**: Airbnb does not ship a native dark mode in the extracted product surfaces; this document describes the single light-mode theme only.

# Design System Inspired by Ant
> Category: Professional & Corporate
> Structured, enterprise-focused design system emphasizing clarity, consistency, and efficiency for data-dense web applications.
## 1. Visual Theme & Atmosphere
Structured, enterprise-focused design system emphasizing clarity, consistency, and efficiency for data-dense web applications.
- **Visual style:** data-dense, enterprise
- **Color stance:** primary, neutral, success, warning, danger
- **Design intent:** Keep outputs recognizable to this style family while preserving usability and readability.
## 2. Color
- **Primary:** `#1677FF` — Token from style foundations.
- **Secondary:** `#8B5CF6` — Token from style foundations.
- **Success:** `#16A34A` — Token from style foundations.
- **Warning:** `#D97706` — Token from style foundations.
- **Danger:** `#DC2626` — Token from style foundations.
- **Surface:** `#FFFFFF` — Token from style foundations.
- **Text:** `#111827` — Token from style foundations.
- **Neutral:** `#FFFFFF` — Derived from the surface token for official format compatibility.
- Favor Primary (#1677FF) for CTA emphasis.
- Use Surface (#FFFFFF) for large backgrounds and cards.
- Keep body copy on Text (#111827) for legibility.
## 3. Typography
- **Scale:** 12/14/16/20/24/32
- **Families:** primary=Plus Jakarta Sans, display=Plus Jakarta Sans, mono=JetBrains Mono
- **Weights:** 100, 200, 300, 400, 500, 600, 700, 800, 900
- Headings should carry the style personality; body text should optimize scanability and contrast.
## 4. Spacing & Grid
- **Spacing scale:** 4/8/12/16/24/32
- Keep vertical rhythm consistent across sections and components.
- Align columns and modules to a predictable grid; avoid ad-hoc offsets.
## 5. Layout & Composition
- Prefer clear content blocks with consistent internal padding.
- Keep hierarchy obvious: headline → support text → primary action.
- Use whitespace to separate concerns before adding borders or shadows.
## 6. Components
- Buttons: primary action uses `#1677FF`; secondary actions stay neutral.
- Inputs: strong focus-visible states, clear labels, and predictable error messaging.
- Cards/sections: use consistent radii, spacing, and elevation strategy across the page.
## 7. Motion & Interaction
- Use subtle transitions that emphasize Primary (#1677FF) as the interaction signal.
- Default to short, purposeful transitions (150–250ms) with stable easing.
- Ensure hover, focus-visible, active, disabled, and loading states are explicit.
## 8. Voice & Brand
- Tone should reflect the visual style: concise, confident, and product-specific.
- Keep microcopy action-oriented and avoid generic filler language.
- Preserve the style identity in headlines while keeping UI labels literal and clear.
## 9. Anti-patterns
- Do not introduce off-palette colors when an existing token can solve the problem.
- Do not flatten hierarchy by using the same type size/weight for all text.
- Do not add decorative effects that reduce readability or accessibility.
- Do not mix unrelated visual metaphors in the same interface.

# Design System Inspired by Apple
> Category: Media & Consumer
> Consumer electronics. Premium white space, SF Pro, cinematic imagery.
## 1. Visual Theme & Atmosphere
Apple's web language is a precision editorial system that alternates between gallery-like calm and retail-density information blocks. The visual tone stays restrained: broad neutral canvases, quiet chrome, and product imagery given almost all of the expressive weight. The interface is engineered to disappear so hardware, materials, and finish options become the narrative foreground.
Across the five analyzed pages, the rhythm is consistent but not monolithic. Marketing surfaces (homepage and Environment) use cinematic black-and-light chaptering, while commerce surfaces (Store and Shop flows) introduce tighter spacing, more utility controls, and denser card stacks without breaking the core brand grammar. The result is one system with two gears: showcase mode and transaction mode.
Typography is the stabilizer. SF Pro Display carries hero and merchandising hierarchy with compact line heights and controlled tracking, while SF Pro Text handles product metadata, navigation, filters, and dense selection UI. The typography stays understated, but the scale range is wide enough to support both billboard hero messaging and micro utility labels.
**Key Characteristics:**
- Binary section rhythm: deep black scenes (`#000000`) alternating with pale neutral fields (`#f5f5f7`)
- Single blue accent family for action and link semantics (`#0071e3`, `#0066cc`, `#2997ff`)
- Dual operating modes in one system: cinematic showcase modules and dense commerce configurators
- Heavy reliance on imagery and material finishes; UI chrome remains visually thin
- Tight headline metrics (SF Pro Display, semibold) paired with compact body/link typography (SF Pro Text)
- Pill and capsule geometry as signature action language (`18px` to `980px` and circular controls)
- Depth used sparingly; contrast and surface separation do most of the layering work
- Multi-page color-block rhythm: black hero chapters -> pale neutral merchandising fields -> utility white retail surfaces -> dark micro-surfaces for controls
## 2. Color Palette & Roles
> **Source Pages:** `https://www.apple.com/`, `https://www.apple.com/environment/`, `https://www.apple.com/store`, `https://www.apple.com/shop/buy-iphone/iphone-17-pro`, `https://www.apple.com/shop/accessories/all`
### Primary
- **Absolute Black** (`#000000`): Immersive hero canvases, high-drama product chapters, deep UI anchors.
- **Pale Apple Gray** (`#f5f5f7`): Main light surface for feature bands, comparison blocks, and editorial transitions.
- **Near-Black Ink** (`#1d1d1f`): Primary text and dark-fill control color on light canvases.
### Secondary & Accent
- **Apple Action Blue** (`#0071e3`): Primary action fill and focus-signaling brand accent.
- **Body Link Blue** (`#0066cc`): Inline link color optimized for long-form readability.
- **High-Luminance Link Blue** (`#2997ff`): Bright link treatment on darker scenes where stronger contrast is required.
### Surface & Background
- **Pure White Canvas** (`#ffffff`): Retail/product-list backgrounds and dense transactional sections.
- **Graphite Surface A** (`#272729`): Dark card and media-control context layer.
- **Graphite Surface B** (`#262629`): Slightly deeper dark utility layer for control groupings.
- **Graphite Surface C** (`#28282b`): Elevated dark supporting surfaces.
- **Graphite Surface D** (`#2a2a2c`): Darkest elevated step used for separation in richer dark scenes.
### Neutrals & Text
- **Secondary Neutral Gray** (`#6e6e73`): Body secondary copy, helper descriptions, tertiary metadata.
- **Soft Border Gray** (`#d2d2d7`): Dividers, subtle outlines, and muted utility containment.
- **Mid Border Gray** (`#86868b`): Stronger field outlines in product-configuration and filter contexts.
- **Utility Dark Gray** (`#424245`): Dark-neutral text/surface crossover in store contexts.
### Semantic & Accent
- **Selection/Focus Signal** (`#0071e3`): Shared focus and selected-state signal across marketing and commerce contexts.
- **Error/Warning/Success**: No distinct semantic palette was consistently visible in the extracted surface set.
### Gradient System
- The extracted pages are overwhelmingly solid-surface driven. Visual richness comes from photography and finish rendering rather than persistent UI gradients.
## 3. Typography Rules
### Font Family
- **Display Family:** `SF Pro Display`, fallbacks `SF Pro Icons, Helvetica Neue, Helvetica, Arial, sans-serif`
- **Text Family:** `SF Pro Text`, fallbacks `SF Pro Icons, Helvetica Neue, Helvetica, Arial, sans-serif`
- **Usage Split:** Display family handles hero/product headlines and merchandising headings; Text family handles navigation, controls, labels, and dense commerce copy.
### Hierarchy
| Role | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|--------|-------------|----------------|-------|
| Hero Display XL | 80px | 600 | 1.00-1.05 | -1.2px | Environment/store hero scale |
| Hero Display L | 56px | 600 | 1.07 | -0.28px | Homepage hero moments |
| Section Display | 48px | 500-600 | 1.08 | -0.144px | Major chapter headings |
| Product Heading | 40px | 600 | 1.10 | normal | Product and campaign section titles |
| Feature Display | 38px | 600 | 1.21 | 0.152px | Device and merchandising callouts |
| Promo Display | 32px | 300-600 | 1.09-1.13 | 0.128px to 0.352px | Module-level sub-heroes |
| Card/Product Title | 28px | 600 | 1.14 | 0.196px | Tile-level naming and key copy |
| Utility Heading | 24px | 600 | 1.17 | 0.216px / -0.2px | Configurator and grouped content headers |
| Link/Action Heading | 21px | 600 | 1.14-1.38 | 0.231px | Larger promotional links |
| Subhead | 19px | 600 | 1.21 | 0.228px | Compact section intros |
| Body Primary | 17px | 400 | 1.47 | -0.374px | Standard body and retail descriptions |
| Body Emphasis | 17px | 600 | 1.24 | -0.374px | Emphasized labels and key values |
| Control Label | 14px | 400-600 | 1.29-1.47 | -0.224px | Buttons, helper labels, compact nav text |
| Micro UI | 12px | 400-600 | 1.00-1.33 | -0.12px | Fine print, micro labels |
| Legal/Meta | 10px | 400 | 1.30-1.47 | -0.08px | Dense metadata and legal support text |
### Principles
- **Continuity across page types:** The same typographic DNA spans cinematic launches and product-purchase flows, preventing a brand split between marketing and commerce.
- **Compression at scale:** Display tiers use tight leading and controlled tracking to feel machined and product-first.
- **Readable density at retail depth:** SF Pro Text balances compactness with enough vertical rhythm for long product lists and option matrices.
- **Measured weight ladder:** 600 is the dominant emphasis weight; 700 appears selectively; 300 is used sparingly for contrast in larger lines.
### Note on Font Substitutes
- Closest freely available substitutes: `Inter` for text-heavy implementation and `SF Pro Display-like` metrics approximated with `Inter Tight` for headings.
- When substituting, increase line-height slightly (+0.02 to +0.06) on body sizes and reduce negative tracking intensity to preserve readability.
## 4. Component Stylings
### Buttons
- **Primary Fill Action:** `#0071e3` background, `#ffffff` text, 8px radius, compact horizontal padding (commonly 8px 15px). Used for decisive purchase/progression actions.
- **Dark Fill Action:** `#1d1d1f` background, `#ffffff` text, 8px radius. Used when light surfaces need a restrained high-contrast primary.
- **Pill/Capsule Action Family:** large capsule actions at `18px`-`56px` radii and extreme pill links at `980px`. Establishes Apple’s soft but precise call-to-action silhouette.
- **Utility Filter/Button Shells:** light shells (`#fafafc` or translucent white) with subtle gray borders (`#d2d2d7` / `#86868b`) for dense configuration contexts.
- **Pressed Behavior:** active controls commonly reduce scale or shift fill slightly to indicate physical press confirmation.
### Cards & Containers
- **Editorial/Product Cards:** light cards on `#f5f5f7` or white fields with minimal framing and image-first composition.
- **Dark Utility Cards:** graphite steps (`#272729` to `#2a2a2c`) used for overlays, media controls, and dark-context modules.
- **Configurator Panels:** rounded containers (often 12px-18px) with clear but restrained border definition.
- **Carousel/Spotlight Modules:** larger rounded shells (`28px`-`36px`) for featured content lanes.
### Inputs & Forms
- **Retail Input Fields:** translucent or white backgrounds, dark text (`#1d1d1f`), border-led containment (`#86868b`).
- **Selection Controls:** circular/toggle-like control geometry appears frequently in product selection interfaces.
- **Density Strategy:** form fields remain visually quiet to keep device imagery and pricing hierarchy dominant.
### Navigation
- **Global Marketing Nav:** compact dark translucent bar with small-type links and restrained iconography.
- **Store/Sub-shop Nav Layers:** additional utility bars, chips, and segmented controls for category and product narrowing.
- **Link Hierarchy:** link blues remain the primary interactive signal while neutral text supports dense navigation sets.
### Image Treatment
- **Object-First Photography:** hardware and accessories are foregrounded on controlled solid surfaces.
- **High-fidelity finish rendering:** reflective/material details are central to visual persuasion.
- **Mixed framing:** full-bleed hero scenes coexist with rounded retail cards and tightly cropped merchandising thumbnails.
### Other Distinctive Components
- **Product Configurator Matrix:** option stacks and selectors combining chips, radio-style controls, and contextual pricing/summary blocks.
- **Carousel Control Dots/Arrows:** circular control vocabulary in muted overlays for gallery progression.
- **Environment Story Panels:** narrative chapters that blend editorial typography with cinematic product/environment visuals.
## 5. Layout Principles
### Spacing System
- Base unit is effectively `8px`, but the system supports dense micro-steps for precision alignment.
- Frequently reused spacing values across pages: `2`, `4`, `6`, `7`, `8`, `9`, `10`, `12`, `14`, `17`, `20` px.
- Universal rhythm constants visible across both marketing and retail flows: `8px` unit scaffolding with `14-20px` utility intervals for component padding and list spacing.
### Grid & Container
- **Showcase pages:** large central columns with broad horizontal breathing room and full-width color chapters.
- **Commerce pages:** tighter multi-column product and control grids with frequent modular stacking.
- **Container behavior:** constrained readable core with generous outer margins at desktop widths.
### Whitespace Philosophy
- **Scene pacing:** major visual chapters use broad top/bottom breathing room.
- **Information compaction where needed:** retail pages deliberately compress spacing to expose more actionable information per viewport.
- **Contrast-led separation:** section transitions rely more on surface changes than decorative separators.
### Border Radius Scale
- **5px:** tiny utility links/tags and minor small shells.
- **8px-12px:** standard controls and compact fields.
- **16px-18px:** cards, module frames, and commerce panels.
- **28px-36px:** larger module and spotlight containers.
- **56px / 100px / 980px:** capsules, large pills, and signature elongated CTA forms.
- **50%:** circular media and selection controls.
## 6. Depth & Elevation
| Level | Treatment | Use |
|------|-----------|-----|
| Level 0 | Flat neutral surfaces (`#ffffff`, `#f5f5f7`, `#000000`) | Main narrative and product stages |
| Level 1 | Subtle border containment (`#d2d2d7`, `#86868b`) | Filters, input fields, utility cards |
| Level 2 | Soft shadow (`rgba(0,0,0,0.08)` to `rgba(0,0,0,0.22)` where present) | Highlighted cards and elevated merchandise modules |
| Level 3 | Dark-surface stepping (`#272729` -> `#2a2a2c`) | Overlays, media controls, dark utility clusters |
| Accessibility | Blue focus signal (`#0071e3`) | Keyboard and selection emphasis |
Depth is intentionally restrained. Apple favors tonal contrast, surface stepping, and compositional hierarchy over heavy shadow stacks.
### Decorative Depth
- Decorative depth is primarily created by photographic realism and material rendering, not synthetic UI effects.
- Translucent overlays and glass-like utility bars provide mild atmospheric layering in navigation and controls.
## 7. Do's and Don'ts
### Do
- Use the neutral triad (`#000000`, `#f5f5f7`, `#ffffff`) as the structural foundation.
- Reserve blue accents for genuine action and navigation semantics.
- Keep typography tight and deliberate, especially at display scales.
- Maintain the capsule/circle geometry language for controls and key actions.
- Let product imagery carry visual drama; keep chrome understated.
- Use border-led containment in dense retail contexts instead of heavy card ornamentation.
- Preserve clear separation between showcase modules and transactional modules while keeping core tokens shared.
### Don't
- Don’t introduce broad secondary accent palettes that compete with Apple blue.
- Don’t overuse shadows, glow effects, or decorative gradients in core UI chrome.
- Don’t mix unrelated font families or loosen tracking indiscriminately.
- Don’t flatten all corners to a single radius; Apple uses purposeful radius tiers.
- Don’t overload commerce modules with thick borders or loud visual effects.
- Don’t remove neutral contrast cadence between dark and light chapters.
- Don’t treat marketing and purchase flows as separate design systems.
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Small Mobile | 374px and below | Tightened retail controls, single-column product stacks |
| Mobile | 375px-640px | One-column modules, compact action rows, condensed selectors |
| Tablet | 641px-833px | Expanded cards and mixed 1-2 column transitions |
| Tablet Wide | 834px-1023px | More stable multi-column merchandising, larger text blocks |
| Desktop | 1024px-1240px | Full retail layouts and product comparison structures |
| Desktop Wide | 1241px-1440px | Marketing hero expansion and broader section spacing |
| Large Desktop | 1441px+ | Maximum chapter breathing room and wide editorial composition |
### Touch Targets
- Primary and secondary actions are generally presented in tap-friendly pill/button geometries.
- Circular media and selection controls align with minimum touchable intent in mobile contexts.
- Dense commerce UI uses compact labels but maintains clear hit regions via surrounding shape padding.
### Collapsing Strategy
- Marketing hero typography scales down in discrete tiers while preserving hierarchy contrast.
- Product and commerce grids collapse from multi-column to stacked cards with persistent selector visibility.
- Utility navigation compresses into simpler link/control groupings while preserving key actions.
- Option/configuration clusters become vertically sequenced to keep purchase flow linear on small screens.
### Image Behavior
- Product imagery preserves aspect and centrality through breakpoints.
- Hero visuals remain dominant on mobile, with text repositioned around media priority.
- Retail thumbnails stay legible via tighter crop logic and denser card stacking.
- Image-led modules continue to anchor the rhythm as layout density increases.
## 9. Agent Prompt Guide
### Quick Color Reference
- Primary action blue: **Apple Action Blue** (`#0071e3`)
- Inline link blue: **Body Link Blue** (`#0066cc`)
- Dark chapter canvas: **Absolute Black** (`#000000`)
- Light chapter canvas: **Pale Apple Gray** (`#f5f5f7`)
- Primary text on light: **Near-Black Ink** (`#1d1d1f`)
- Secondary text: **Secondary Neutral Gray** (`#6e6e73`)
- Retail border soft: **Soft Border Gray** (`#d2d2d7`)
- Retail border strong: **Mid Border Gray** (`#86868b`)
### Example Component Prompts
- "Design an Apple-style product hero on a black canvas (`#000000`) with SF Pro Display semibold headline (48-56px), concise supporting copy, and two capsule CTAs using `#0071e3` and `#1d1d1f`."
- "Create a commerce configuration panel on white (`#ffffff`) with 18px rounded cards, `#86868b` border fields, SF Pro Text 17px body copy, and compact option selectors."
- "Build a merchandising card grid alternating `#f5f5f7` and white surfaces, with image-first cards, restrained shadows, and 14-17px SF Pro Text metadata."
- "Generate a carousel control cluster using circular buttons (50% radius), muted gray overlays, and clear active feedback for gallery navigation."
- "Compose a mixed marketing + retail page rhythm: dark showcase chapter -> light feature chapter -> dense product list module while keeping blue accents only for actions and links."
### Iteration Guide
1. Lock the neutral foundation first (`#000000`, `#f5f5f7`, `#ffffff`) before tuning accents.
2. Keep blue accents scarce and purposeful; if everything is blue, hierarchy collapses.
3. Tune typography in this order: display scale, body readability, then micro labels.
4. Match radius by component class (field, card, capsule, circle) rather than one-size-fits-all rounding.
5. Increase density gradually when moving from showcase sections to commerce sections.
6. Validate that product imagery remains the strongest visual layer after each revision.
### Known Gaps
- Distinct semantic status colors (error/warning/success) were not consistently visible in the extracted page set.
- Some interaction micro-states vary by module and are not represented as universal system tokens.
- A few retail modules expose context-specific typography overrides that do not appear across all five pages.

# Design System Inspired by Arc Browser
> Category: Productivity & SaaS
> "The browser that browses for you." Translucent surfaces, gradient warmth, sidebar-first layout.
## 1. Visual Theme & Atmosphere
Arc Browser dissolves the boundary between the chrome and the page. Where Chrome and Safari treat the browser frame as a container, Arc treats it as scenery — the toolbar fades into the system wallpaper, the sidebar carries gradient warmth from the user's chosen "theme color", and translucency is everywhere. The visual signature is **frosted glass plus a single saturated gradient** — most often a peach-to-coral or violet-to-fuchsia bloom — that sets the emotional temperature of the entire window.
Typography uses **Inter** for chrome and a custom display serif (`Argent CF` or similar) for marketing — when Arc speaks publicly it speaks editorially, in a serif voice unusual for tech. The product itself is sans-only, with tight tracking and generous line-height.
Shapes are squircle-soft: 12–16px radii on cards, 8px on tabs, 9999px pills for tags. Borders are rare — Arc prefers tinted background washes (`rgba(255, 255, 255, 0.5)` over the gradient) to delineate panes.
**Key Characteristics:**
- Translucent frosted-glass surfaces over a saturated gradient background
- Theme-color gradients (peach-coral, violet-fuchsia, mint-cyan) as the primary mood
- Inter for product chrome, Argent CF (serif) for marketing display
- Squircle-soft 12–16px radii everywhere
- Sidebar-first layout: tabs, spaces, and bookmarks live on the left, not the top
- Color picker is a brand surface — themes are user-driven, not fixed
- Subtle shadows (`0 8px 32px rgba(0,0,0,0.08)`) over the gradient backdrop
## 2. Color Palette & Roles
### Primary Theme Gradients (User-selectable; default is "Sunset")
- **Sunset Start** (`#ff7e5f`): Peach gradient origin.
- **Sunset End** (`#feb47b`): Soft coral gradient terminus.
- **Twilight Start** (`#7f5af0`): Violet gradient origin.
- **Twilight End** (`#e84393`): Fuchsia gradient terminus.
- **Aurora Start** (`#16f2b3`): Mint gradient origin.
- **Aurora End** (`#0db4f7`): Cyan gradient terminus.
### Surface (Frosted)
- **Glass Light** (`rgba(255, 255, 255, 0.7)`): Standard frosted pane over gradient.
- **Glass Medium** (`rgba(255, 255, 255, 0.5)`): Hover state, tab pill background.
- **Glass Heavy** (`rgba(255, 255, 255, 0.85)`): Active pane, command bar.
- **Glass Dark** (`rgba(20, 20, 25, 0.6)`): Dark-mode frosted surface.
### Ink & Text
- **Ink Primary** (`#1a1a1f`): Primary text on light frosted surface.
- **Ink Secondary** (`#54545a`): Secondary text, tab title at rest.
- **Ink Muted** (`#8c8c93`): Tertiary, captions, URL bar.
- **Ink Inverse** (`#fafafa`): Text on dark frosted surface.
### Border & Divider
- **Border Glass** (`rgba(255, 255, 255, 0.4)`): Frosted-edge border.
- **Border Hairline** (`rgba(0, 0, 0, 0.06)`): Hairline divider on light surface.
- **Border Active** (`rgba(0, 0, 0, 0.18)`): Active tab outline.
### Brand Accent
- **Arc Coral** (`#ff5f5f`): Default brand color — used in marketing, `arc.net`.
- **Arc Lavender** (`#b794f4`): Secondary brand accent.
### Semantic
- **Success** (`#48bb78`): Toast confirmation.
- **Warning** (`#f6ad55`): Permission prompt.
- **Error** (`#f56565`): Form validation.
## 3. Typography Rules
### Font Family
- **Display / Marketing**: `Argent CF`, with fallback: `'Source Serif Pro', Georgia, serif`
- **Body / UI**: `Inter`, with fallback: `system-ui, -apple-system, BlinkMacSystemFont, sans-serif`
- **Code / Mono**: `Berkeley Mono`, with fallback: `ui-monospace, Menlo, Consolas, monospace`
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Marketing Hero | Argent CF | 72px (4.5rem) | 400 | 1.05 | -0.03em | Editorial display, marketing only |
| Section Heading | Argent CF | 40px (2.5rem) | 400 | 1.15 | -0.02em | Marketing section titles |
| Page H1 | Inter | 32px (2rem) | 700 | 1.2 | -0.02em | Settings, command bar header |
| Page H2 | Inter | 22px (1.375rem) | 600 | 1.25 | -0.01em | Sub-section |
| Tab Title | Inter | 13px (0.8125rem) | 500 | 1.3 | -0.005em | Sidebar tab label |
| Body | Inter | 15px (0.9375rem) | 400 | 1.55 | normal | Settings prose, tooltips |
| Caption | Inter | 12px (0.75rem) | 500 | 1.4 | 0.01em | URL bar protocol, metadata |
| Code | Berkeley Mono | 13px (0.8125rem) | 400 | 1.5 | normal | URL bar, devtools |
### Principles
- **Serif moments are rare**: Argent CF appears only in marketing. The product is sans-only.
- **Title size is small**: tabs render at 13px so a long sidebar of 30+ tabs stays scannable.
- **Tracking tightens with size**: -0.03em at 72px, returning to normal by 15px.
## 4. Component Stylings

# Atelier Zero
> Category: Editorial · Studio
> A magazine-grade, collage-driven visual system: warm paper canvas, surreal
> plaster-and-architecture imagery, oversized display type, hairline rules,
> Roman-numeral section markers, and tiny editorial annotations.
> Inspired by the production values of high-end print magazines (Monocle,
> Apartamento, IDEA) translated into a working website.
## 1. Visual Theme & Atmosphere
A small, high-craft studio's annual report rendered as a webpage. The
canvas is warm handmade paper. Every surface earns its lines. Type does
the heavy lifting; collage imagery does the storytelling. Coral provides
the only spark of warmth; mustard, olive, and bone are quiet
companions. The page feels printed, slightly aged, and intentionally
restrained — never noisy, never neon.
- **Visual style:** editorial, collage, museum-catalog calm.
- **Posture:** asymmetric, generous, top-biased.
- **Reading rhythm:** Roman numerals (I, II, III…) walk the reader
through the page like chapters in a printed essay.
- **Mood:** intelligent, tactile, slightly poetic, unmistakably
international.
### Print production references
The three magazines are not interchangeable inspiration — each owns a
specific dimension of the system. When a brief asks "shift it closer to
X", consult this map before changing tokens:
- **Monocle:** warm paper stock (`#efe7d2`), tight body leading (~1.55),
monospace coordinates and SHA stamps, the international metadata
strip ("Filed under …"), the small ★ in the nav.
- **Apartamento:** surreal collage composition (plaster + architecture
+ small human figure), torn-edge textures inside the imagery, the
rotated side notes, and the willingness to leave generous negative
space around an image.
- **IDEA:** Roman-numeral section walks (I → VIII), oversized
italic-serif words mixed inline with bold sans (Playfair Italic 500
inside Inter Tight 800), hairline rules threading through method
steps, the closing mega-word footer.
## 2. Color
All values are tokens. Do not invent new hex.
- **Paper:** `#efe7d2` — primary background, warm ivory.
- **Paper-warm:** `#ece4cf` — second-tier surface tint.
- **Paper-dark:** `#ddd2b6` — subtle wells, cards on cards.
- **Bone:** `#f7f1de` — elevated card surface (always on Paper).
- **Ink:** `#15140f` — body text, primary buttons, strong rules.
- **Ink-soft:** `#2a2620` — secondary text, dense paragraphs.
- **Ink-mute:** `#5a5448` — captions, lab descriptions.
- **Ink-faint:** `#8b8676` — coordinates, page numbers, microcopy.
- **Coral (accent):** `#ed6f5c` — single hot accent. CTA fills,
Roman-numeral marks, eyebrow underlines, pulse dots, "fin." marks.
- **Coral-soft:** `#f08e7c` — hover/secondary coral states only.
- **Mustard:** `#e9b94a` — used sparingly: a single ★ in the nav, a
highlighted ring in stats, occasional dot on a numbered annotation.
- **Olive:** `#6e7448` — quiet third accent for tags or partner glyphs.
### Color rules
- One **coral** moment per ~600vh. If two CTAs are coral, the
Roman numerals should be ink-faint instead.
- Mustard is never used for a CTA. It is jewelry.
- Pure white (`#fff`) only inside the dark "selected work" panel as
inverse text. Never on Paper.
- Pure black is forbidden. The darkest value is `Ink #15140f`.
### Why single-accent (not multi-accent)
Multi-accent editorial systems (e.g. *The New Yorker* using red for
Opinion and teal for Culture) work when the publication has stable
content categories and a long-term reader who learns the code. A
single-shot studio landing page does not have that runway. One coral
moment per ~600vh forces the agent to pick the single most important
beat per viewport instead of balancing two chromatic hierarchies, and
keeps the page calibrated to the warm-paper canvas. Mustard and olive
exist as **jewelry** (≤1% surface area: a star, a dot, a partner glyph)
— never as semantic signals, and never as CTA fills.
### Surface noise
Every page MUST overlay a faint paper noise texture using a fixed,
pointer-events-disabled `::before` pseudo-element with a
multiply-blend SVG turbulence at ~5–7% opacity, plus two soft
radial gradients in `rgba(106, 92, 56, 0.06)` to simulate
hand-pressed paper warmth.
## 3. Typography
### Families
- **Display / sans:** `Inter Tight` 700–900 weights — headlines, section
titles, button text. Letter-spacing `-0.025em` to `-0.04em` at
display sizes.
- **Italic emphasis / serif:** `Playfair Display` Italic, weight 500.
Used inline inside display headlines on emphasized nouns, on Roman
numerals, on testimonial quotes, on the brand mark `Ø`.
- **Body:** `Inter` 300–500 — paragraph copy, lab descriptions.
- **Mono:** `JetBrains Mono` 400–500 — code spans, coordinates,
SHAs, plate numbers ("FIG. 01 / OD-26").
### Scale (px)
`9.5 · 10.5 · 11 · 13 · 14 · 16 · 17 · 22 · 26 · 38 · 54 · 66 · 78 · 90 · 200`
### Headline construction
Display headlines mix **bold sans** and **italic serif** in the same
line. The serif italic carries the emotional words; the sans carries
the structure. End every section H1/H2 with a coral period — `<span
class="dot">.</span>`.
```
Designing intelligence with skills, taste, and code.
^^^^^^^^^ ^^^^^^^^ ^^^^^ ^^^^
sans bold serif italic coral dot
```
### Microcopy
- **Eyebrow / label:** 11px Inter Tight 600, `letter-spacing: 0.22em`,
uppercase, coral, prefixed with an 18px coral hairline.
- **Coordinates:** 10px JetBrains Mono, `letter-spacing: 0.04em`,
ink-faint, e.g. `52.5200° N · 13.4050° E`.
- **Page-of-pages:** `004 / 008` in Inter Tight 11px ink-faint.
- **Roman numerals:** Playfair Italic 14px, coral, `I.` `II.` `III.` etc.
at the head of every section rule.
## 4. Spacing & Grid
- **Container:** max-width `1360px`, side padding `64px` desktop,
`44px` at ≤1280, `32px` at ≤1080, `24px` at ≤880.
- **Section padding:** `130px` top+bottom desktop, `90px` for
tight sections, `80px` ≤560.
- **Grid:** 12-column conceptual, executed as CSS Grid with
task-specific column ratios. Hero is `0.78fr 1.22fr`.
- **Vertical rhythm:** 8px baseline. Allow 32–48px between
paragraph blocks.
- **Side rails:** Two 36px-wide fixed vertical strips on the left and
right edges of the viewport, each containing a single rotated
text label in 10px Inter Tight 600 letter-spaced 0.42em.
## 5. Layout & Composition
- **Top metadata strip** is mandatory: a single horizontal bar above
the nav containing the volume/issue, a "Filed under …" badge, and a
live-status pulse with version + locale. Inter Tight 10.5px,
ink-faint, 1px ink-line border-bottom.
- **Section rule** is mandatory at the top of every section:
`[Roman.] · [meta middle] · [page-of-008]`.
- **Image annotations**: every featured image carries 4 corner
brackets (1px hairlines, 22×22), at least 1 plate number
("Plate Nº 08"), and a coordinate or SHA.
- **Hero must extend above the fold** at 1440×900 minimum. The image
fills the viewport vertically (`calc(100vh - 160px)`), aligned to
the right edge.
- **Method sections** must use a 4-step layout with a horizontal
hairline running through the step heads at the same Y, with
`→` separators between titles.
## 6. Components
### Buttons
- **Primary:** coral fill `#ed6f5c`, white label, `999px` radius,
`14px 22px` padding, with a white arrow `↗` SVG at 14px and a
coral 0,14,26,-16 rgba shadow.
- **Ghost:** transparent, `1px solid rgba(21,20,15,0.2)` border,
ink label, same radius and padding.
### Cards
- **Bone-fill cards** (`#f7f1de`), 18px radius, 28×26 padding,
inset 1px ink-at-6% ring + 30/60/-30/15 ambient shadow.
- Each card has a `01–04` italic serif num plus a tag eyebrow on
the same row.
- A bottom-right 28px circular arrow mark turns coral on hover.
### Pill filters
- 10×18 padding, 999px, `1px solid line` border, transparent.
- Active state: coral fill, white label, count separator opacity 0.7.
### Stat rings
- 32–34px circular dashed rings carrying a 2-digit number; one ring
per row may be coral-stroked to denote the highlighted stat.
### Page numbers / index card
- Hero artwork carries a small bordered card on the right edge with
`01–04` index entries. The current entry uses bold ink; the rest
ink-faint. Each item prefixes the digit with a coral `01` token.
### Side rails
- Fixed 36px vertical strips at left + right edges, hidden below
1280px. Each contains rotated 10px Inter Tight uppercase text
letter-spaced 0.42em, never wraps.
### Roman section rules
Every section opens with a `.sec-rule`: top hairline 1px, then a
flex row containing `[Roman]`, a centered metadata cluster, and
the page-of-008 counter on the right.
## 7. Motion & Interaction
- **Pulse dot:** 6×6 coral circle at top metadata bar and footer,
`pulse 2.4s ease-in-out infinite` between 1.0 and 0.35 opacity.
- **Card hover:** translateY(-3px), arrow mark fills coral.
- **Button hover:** translateY(-1px), darker coral fill.
- **Pill hover:** ink-at-4% wash.
- **Transitions:** `0.18s ease` everywhere; never longer than `0.25s`.
- **No parallax, no scroll-jacking, no auto-rotators.** Editorial
pages do not animate themselves at the user.
## 8. Voice & Brand
- Headlines mix declarative and italicized emotional words.
- Body copy is plain-spoken and specific. Quote real numbers
(12 / 31 / 72), real coordinates (52.5200° N · 13.4050° E),
real commands (`pnpm tools-dev`).
- Microcopy uses publication metaphors: "Filed under", "Plate Nº",
"Vol. 01 / Issue Nº 26", "FIN.", "MMXXVI", "Edited by".
- Latin numerals — Roman for sections, Arabic for stats.
## 9. Anti-patterns
- ❌ No drop shadows above 30px blur. No gradients on text.
- ❌ No emoji in product copy. ★ is allowed once in the nav CTA.
- ❌ No glassmorphism, no neon, no neumorphism, no rounded
corners larger than 24px (except 32px on the dark "Selected Work" panel).
- ❌ No more than one coral CTA per viewport.
- ❌ No collage image without corner brackets and at least one
monospace annotation.
- ❌ No Roman numeral skipped — sections must be sequential.
- ❌ No pure white, no pure black, no pure 100%-saturation accent.
### Anti-patterns specific to AI-generated imagery
This system is paired with `gpt-image-fal` / `gpt-image-azure` via the
open-design-landing skill. Several common image-model defaults will
silently break the Atelier Zero aesthetic, so they are forbidden in
every collage prompt and rejected on visual review:
- ❌ No lens flares, light leaks, bloom, or cinematic post-FX. The
paper-and-museum mood is matte, not cinematic.
- ❌ No glitch, datamosh, RGB-split, or scanline artifacts.
- ❌ No photorealistic human faces or stock-portrait people. Plaster
fragments, busts, and small scale figures only — eyes never look at
the viewer.
- ❌ No visible AI signatures, watermarks, generator logos, or
hallucinated model captions. The rendered surface must read as a
printed page, not a model output.
- ❌ No DSLR-style shallow depth-of-field bokeh on the collage
fragments — every plane stays in focus.
## 10. Responsive Behavior
- **Desktop ≥ 1280px:** full container, two side rails visible,
metadata strip shows all three columns.
- **Laptop 1080–1279px:** side rails hidden, container 32–44px
padding, metadata strip's middle column collapses.
- **Tablet 880–1079px:** hero / about / capabilities / testimonial
/ cta grids collapse to 1 column at 50px gap. Method becomes 2×2,
the connecting hairline is removed. Nav links + brand-meta hide;
brand-mark + CTA remain.
- **Phone < 560px:** all multi-column grids become 1 col;
section padding drops to 80px.
## 11. Imagery
This system is collage-first. Every page-level image must be
generated to match these constraints:
- **Background:** warm ivory paper with subtle grain, faint vertical
folds, drafting registration marks.
- **Subject:** classical plaster head fragments, brutalist concrete
blocks, archways, stairs, tree, sky cutouts, one small human figure.
- **Color overlay:** restrained — cream, stone, charcoal, washed
coral, occasional mustard, pale-blue inside small sky cutouts.
- **Annotations baked in:** thin hairline circles, crosshairs,
dotted matrices, numbered tags. Never typography that conflicts
with on-page copy.
See `skills/open-design-landing/assets/imagegen-prompts.md` for the
working prompt pack and per-section variants. All renders should be
at 16:9 (heroes) or 1:1 (cards / about / cta), saved as PNG, ≥1024px
on the long edge.
## 12. Agent Prompt Guide
When generating against this design system:
- The page is a **printed magazine** that happens to deploy. Lean
into print metaphors before web metaphors.
- Always include the metadata strip, the side rails, the Roman
section rules, and a footer with a giant `Open Design.` (or brand)
word at clamp(70px, 13vw, 200px).
- Coral is a single character on stage. If you find yourself
reaching for a second coral element in the same viewport, use
ink-faint or mustard instead.
- Italic serif words inside display headlines should always be
emotional nouns: *intelligence*, *taste*, *memorable*, *open*,
*visually*. Never verbs, never adjectives.
- If asked for "more dramatic," the lever is **typography size**
(clamp top to 90–110px) and **image height** (push to 100vh - nav).
Do not reach for color.
- If asked for "more minimal," remove decorative side notes and
reduce annotations to one per image — never remove the Roman
rules or the metadata strip.

# Design System Inspired by Bento
> Category: Layout & Structure
> Modular grid layout with card-like blocks, clear hierarchy, soft spacing, and subtle visual contrast for organized, scannable interfaces.
## 1. Visual Theme & Atmosphere
Modular grid layout with card-like blocks, clear hierarchy, soft spacing, and subtle visual contrast for organized, scannable interfaces.
- **Visual style:** modern, clean
- **Color stance:** primary, neutral, success, warning, danger
- **Design intent:** Keep outputs recognizable to this style family while preserving usability and readability.
## 2. Color
- **Primary:** `#FAD4C0` — Token from style foundations.
- **Secondary:** `#80A1C1` — Token from style foundations.
- **Success:** `#16A34A` — Token from style foundations.
- **Warning:** `#D97706` — Token from style foundations.
- **Danger:** `#DC2626` — Token from style foundations.
- **Surface:** `#FFF5E6` — Token from style foundations.
- **Text:** `#111827` — Token from style foundations.
- **Neutral:** `#FFF5E6` — Derived from the surface token for official format compatibility.
- Favor Primary (#FAD4C0) for CTA emphasis.
- Use Surface (#FFF5E6) for large backgrounds and cards.
- Keep body copy on Text (#111827) for legibility.
## 3. Typography
- **Scale:** 12/14/16/20/24/32
- **Families:** primary=Inter, display=Inter, mono=JetBrains Mono
- **Weights:** 100, 200, 300, 400, 500, 600, 700, 800, 900
- Headings should carry the style personality; body text should optimize scanability and contrast.
## 4. Spacing & Grid
- **Spacing scale:** 4/8/12/16/24/32
- Keep vertical rhythm consistent across sections and components.
- Align columns and modules to a predictable grid; avoid ad-hoc offsets.
## 5. Layout & Composition
- Prefer clear content blocks with consistent internal padding.
- Keep hierarchy obvious: headline → support text → primary action.
- Use whitespace to separate concerns before adding borders or shadows.
## 6. Components
- Buttons: primary action uses `#FAD4C0`; secondary actions stay neutral.
- Inputs: strong focus-visible states, clear labels, and predictable error messaging.
- Cards/sections: use consistent radii, spacing, and elevation strategy across the page.
## 7. Motion & Interaction
- Use subtle transitions that emphasize Primary (#FAD4C0) as the interaction signal.
- Default to short, purposeful transitions (150–250ms) with stable easing.
- Ensure hover, focus-visible, active, disabled, and loading states are explicit.
## 8. Voice & Brand
- Tone should reflect the visual style: concise, confident, and product-specific.
- Keep microcopy action-oriented and avoid generic filler language.
- Preserve the style identity in headlines while keeping UI labels literal and clear.
## 9. Anti-patterns
- Do not introduce off-palette colors when an existing token can solve the problem.
- Do not flatten hierarchy by using the same type size/weight for all text.
- Do not add decorative effects that reduce readability or accessibility.
- Do not mix unrelated visual metaphors in the same interface.

# Design System Inspired by Binance.US
> Category: Fintech & Crypto
> Crypto exchange. Bold yellow accent on monochrome, trading-floor urgency.
## 1. Visual Theme & Atmosphere
Binance.US radiates the polished urgency of a digital trading floor — a space where money moves and decisions happen in seconds. The design is a two-tone composition that alternates between stark white trading surfaces and deep near-black panels (`#222126`), creating a visual rhythm that mirrors the bull-and-bear duality of crypto markets. Binance Yellow (`#F0B90B`) cuts through this monochrome foundation like a gold ingot on a steel desk — unmistakable, confident, and engineered to guide every eye toward the next action.
The interface speaks the language of fintech trust. Custom BinancePlex typography gives every headline and data point a proprietary gravitas, while generous whitespace and restrained decoration keep the focus on numbers, charts, and call-to-action buttons. The design avoids visual complexity in favor of operational clarity — every element exists to either inform or convert. Product screenshots of the mobile trading app dominate the middle sections, presented on floating device mockups against golden gradients, reinforcing that this is a platform you carry with you.
What makes Binance.US distinctive is the tension between warmth and precision. The golden yellow brand color — warm, optimistic, almost celebratory — lives inside a system of cold, clinical grey text and razor-sharp borders. This isn't a playful fintech like Robinhood or a corporate fortress like Fidelity — it's a crypto-native platform that wraps cutting-edge trading technology in the visual language of established finance.
**Key Characteristics:**
- Two-tone light/dark section alternation — white surfaces for trust, dark panels for depth
- Binance Yellow (`#F0B90B`) as the singular accent color driving all primary actions
- BinancePlex custom typeface providing proprietary brand identity at every text level
- Pill-shaped CTA buttons (50px radius) that demand attention
- Floating device mockups on golden gradients for product showcasing
- Crypto price tickers with real-time data prominently displayed
- Shadow-light elevation with subtle 5% opacity card shadows
## 2. Color Palette & Roles
### Primary
- **Binance Yellow** (`#F0B90B`): The signature — primary CTA backgrounds, brand accent, active states, link color. The single most important color in the system
- **Binance Gold** (`#FFD000`): Lighter gold variant used for pill button borders, secondary CTA fills, and golden gradient highlights
- **Light Gold** (`#F8D12F`): Soft gold for gradient endpoints and hover-adjacent states
### Secondary & Accent
- **Active Yellow** (`#D0980B`): Darkened yellow for active/pressed button states — the "clicked" gold
- **Focus Blue** (`#1EAEDB`): Accessibility focus state — appears on hover and focus for all interactive elements
### Surface & Background
- **Pure White** (`#FFFFFF`): Primary page canvas, card surfaces, light section backgrounds
- **Snow** (`#F5F5F5`): Subtle surface differentiation, input backgrounds, alternating row fills
- **Binance Dark** (`#222126`): Dark section backgrounds, footer canvas, "Trusted by millions" panel — a near-black with a faint purple undertone
- **Dark Card** (`#2B2F36`): Card surfaces within dark sections, elevated dark containers
- **Ink** (`#1E2026`): Button text on yellow backgrounds, deepest text color on light surfaces
### Neutrals & Text
- **Primary Text** (`#1E2026`): Main body text, headings on light backgrounds — near-black with slight warmth
- **Secondary Text** (`#32313A`): Navigation links, descriptive copy on light surfaces
- **Slate** (`#848E9C`): Tertiary text, metadata, timestamps, footer links — the workhorse grey
- **Steel** (`#686A6C`): Disabled-adjacent text, subtle labels
- **Muted** (`#777E90`): Secondary navigation links, less prominent footer text
- **Hover Dark** (`#1A1A1A`): Universal link hover color — text darkens on hover
### Semantic & Accent
- **Crypto Green** (`#0ECB81`): Positive price movement, success states, "up" indicators
- **Crypto Red** (`#F6465D`): Negative price movement, error states, "down" indicators
- **Border Light** (`#E6E8EA`): Standard card and section borders on light backgrounds
- **Border Gold** (`#FFD000`): Active/selected state borders, pill button outlines
### Gradient System
- **Golden Glow**: Radial gradient from `#F0B90B` center to `#F8D12F` edge — used behind product mockup screenshots
- **Dark Fade**: Linear gradient from `#222126` to transparent — used for dark section transitions
- **Hero Shimmer**: Subtle animated gold gradient on hero section accents
## 3. Typography Rules
### Font Family
**Primary:** BinancePlex (custom proprietary typeface designed by Binance)
- Fallbacks: Arial, sans-serif
- Replaced DIN Next to solve multi-language spacing issues
- Available in weights: 400 (Regular), 500 (Medium), 600 (SemiBold), 700 (Bold)
**System:** system-ui stack for cookie banners and third-party UI
- Fallbacks: Segoe UI, Roboto, Helvetica, Arial
### Hierarchy
| Role | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|--------|-------------|----------------|-------|
| Display Hero | 60px | 700 | 1.08 | — | Hero headlines, maximum impact |
| Display Secondary | 34px | 700 | 1.00 | — | Section titles on dark backgrounds |
| Heading 1 | 28px | 500 | 1.00 | — | Major section headings |
| Heading 2 | 24px | 700 | 1.00 | — | Feature headings, card titles |
| Heading 3 | 24px | 600 | 1.00 | — | Subsection headings |
| Heading 4 | 20px | 600 | 1.25 | — | Card headings, feature labels |
| Body Large | 20px | 500 | 1.50 | — | Hero subtitle, lead paragraphs |
| Body | 16px | 500 | 1.50 | — | Standard body text |
| Body SemiBold | 16px | 600 | 1.30 | — | Emphasized body, nav links |
| Body Bold | 16px | 700 | 1.50 | — | Strong emphasis text |
| Button | 16px | 600 | 1.25 | 0.16px | Primary button text |
| Button Small | 14.4px | 600 | 1.60 | 0.72px | Secondary buttons, wider tracking |
| Caption | 14px | 500 | 1.43 | — | Metadata, labels, prices |
| Caption SemiBold | 14px | 600 | 1.50 | — | Emphasized captions |
| Small | 12px | 600 | 1.00 | — | Tags, badges, fine print |
| Tiny | 11px | 500 | 1.00 | — | Micro-labels, chart annotations |
### Principles
BinancePlex is engineered for data-dense interfaces where numbers and text must coexist at multiple scales. The typeface has tabular numerals by default — critical for price columns and portfolio values that need perfect vertical alignment. Weights lean toward the heavier end (500-700), giving the interface a sense of authority and confidence that's essential for a financial platform. The tight line-heights (1.00-1.25) on headings create a stacked, compressed feel that mirrors the density of trading dashboards, while body text opens up to 1.50 for comfortable reading of educational and marketing content.

## 5. Layout Principles
### Spacing System
Base unit: 8px
| Token | Value | Use |
|-------|-------|-----|
| space-1 | 4px | Tight inline gaps, icon padding |
| space-2 | 8px | Base unit, button icon gaps, tight margins |
| space-3 | 12px | Card internal padding, input padding |
| space-4 | 16px | Standard padding, section margins |
| space-5 | 20px | Card gaps, medium padding |
| space-6 | 24px | Section internal padding |
| space-7 | 32px | Section breaks, large padding |
| space-8 | 48px | Major section padding |
| space-9 | 64px | Hero section padding |
| space-10 | 80px | Large section spacing |
### Grid & Container
- Max container width: 1200px (centered)
- Hero area: single column with side-by-side text + image above 1024px
- Feature grid: 3-column on desktop, single column on mobile
- Product showcase: 2-column (text + device mockup)
- Horizontal padding: 32px desktop, 16px mobile
- Grid gap: 24px between feature cards
### Whitespace Philosophy
Binance.US uses whitespace as a trust signal. Generous padding around the hero section and between content blocks creates a sense of spaciousness that counters the information density typically associated with crypto exchanges. The light sections breathe — wide margins around headlines and ample spacing between cards — while dark sections compress, packing features into tighter grids to convey capability and depth. The overall rhythm alternates between "inviting entry" (light, spacious) and "deep functionality" (dark, dense).
### Border Radius Scale
| Value | Context |
|-------|---------|
| 1px | Subtle edge softening, fine UI elements |
| 2px | Close buttons, micro-interactive elements |
| 6px | Primary buttons (non-pill), small cards |
| 8px | Form inputs, data cards, image containers |
| 10px | Navigation pills, tag containers |
| 12px | Content cards, feature containers |
| 24px | Video containers, hero imagery, large cards |
| 50px | Pill buttons (CTA), search inputs, full-round elements |
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat | No shadow, solid background | Default for inline elements |
| Subtle | `rgba(32, 32, 37, 0.05) 0px 3px 5px` | Content cards, resting state |
| Medium | `rgba(8, 8, 8, 0.05) 0px 3px 5px 5px` | Hovered cards, elevated containers |
| Pill Shadow | `rgb(153,153,153) 0px 2px 10px -3px` | Pill CTA buttons, floating actions |
| Heavy | `rgba(0,0,0) 0px 32px 37px` | Modal overlays, dropdown menus |
Binance.US uses a whisper-light shadow system. Card shadows are barely perceptible at 5% opacity — they exist not for dramatic depth but as subtle ground cues that keep cards from feeling pasted onto the surface. The pill button shadow is the exception: slightly more visible to give CTAs a "floating" quality that invites clicks. The philosophy is pragmatic — in a financial context, heavy shadows feel frivolous, while no shadows at all feel flat and untrustworthy. The 5% sweet spot communicates professionalism.
### Decorative Depth
- **Golden gradient backgrounds**: Behind device mockup sections, radial golden glow centered on the product
- **Dark-to-light section transitions**: Hard cut (no gradient blend) between white and `#222126` sections
- **Price ticker strip**: Flat, borderless, reads as a data bar rather than a decorative element
## 7. Do's and Don'ts
### Do
- Use Binance Yellow (`#F0B90B`) exclusively for primary CTAs and brand accents — it's the single point of color
- Keep light and dark sections strictly alternating for visual rhythm
- Use BinancePlex at weight 500+ for all interactive elements — this is a confidence-forward design
- Apply 50px radius to all primary CTA pill buttons — the signature interactive shape
- Maintain 12px radius on content cards for a polished but not overly rounded feel
- Show real-time data prominently (prices, percentages, stats) — numbers build trust
- Use Slate (`#848E9C`) for all secondary/metadata text — the universal quiet voice
- Keep shadows at 5% opacity or less — barely there but present
### Don't
- Don't introduce additional brand colors — Binance Yellow is the only accent; all other color is data-driven (green up, red down)
- Don't use rounded corners above 12px on content cards — only CTAs and video containers go higher
- Don't add heavy shadows or hover lift effects — this is a restrained financial platform
- Don't use BinancePlex below weight 500 for headings — lighter weights undermine authority
- Don't place yellow text on yellow backgrounds — always ensure high contrast pairing
- Don't mix pill (50px) and square (6px) button styles in the same row
- Don't soften the dark sections — `#222126` should feel authoritative, not grey
- Don't use decorative illustrations — imagery should be product screenshots or data visualizations
- Don't add animation beyond subtle transitions (200ms ease) — financial platforms need stability
- Don't use colored backgrounds for semantic states in cards — keep cards white or dark, use text color for semantic meaning
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | <425px | Single column, stacked hero, hamburger nav, 16px padding |
| Small Mobile | 425-599px | Wider mobile layout, price ticker wraps |
| Tablet Small | 600-768px | 2-column feature grid begins |
| Tablet | 769-896px | Hero side-by-side layout begins |
| Desktop Small | 897-1024px | Full nav expands, 3-column features |
| Desktop | 1024-1280px | Full layout, max content width |
| Large Desktop | 1280-1440px | Increased margins, centered container |
| XL Desktop | >1440px | Max-width container (1200px) with expanded margins |
### Touch Targets
- Minimum touch target: 44x44px (WCAG AAA)
- Pill CTA buttons: 48px height minimum
- Nav links: 44px touch area
- Crypto ticker items: full-width tappable rows on mobile
- App download buttons: large tap zones (50px+)
### Collapsing Strategy
- **Navigation**: Full horizontal links → hamburger menu below 897px; logo and "Get Started" CTA remain visible
- **Hero section**: Side-by-side (text left, image right) → stacked (text top, image below) at 768px
- **Feature grid**: 3-col → 2-col at 768px → 1-col at 600px
- **Price ticker**: Horizontal row → wrapping or scrollable at 600px
- **Section padding**: 64px → 48px → 32px → 16px as viewport narrows
- **Device mockups**: Scale down proportionally, maintain centered positioning
- **Footer**: Multi-column → stacked accordion sections on mobile
### Image Behavior
- Device mockups: CSS-scaled with max-width constraints, maintain aspect ratio
- Hero imagery: contained within rounded containers (24px), scale proportionally
- App screenshots: responsive width with fixed aspect ratio
- QR code: fixed 120px square, hidden on mobile (replaced with direct app store links)

# Design System Inspired by BMW
> Category: Automotive
> Luxury automotive. Dark premium surfaces, precise German engineering aesthetic.
## 1. Visual Theme & Atmosphere
BMW's website is automotive engineering made visual — a design system that communicates precision, performance, and German industrial confidence. The page alternates between deep dark hero sections (featuring full-bleed automotive photography) and clean white content areas, creating a cinematic rhythm reminiscent of a luxury car showroom where vehicles are lit against darkness. The BMW CI2020 design language (their corporate identity refresh) defines every element.
The typography is built on BMWTypeNextLatin — a proprietary typeface in two variants: BMWTypeNextLatin Light (weight 300) for massive uppercase display headings, and BMWTypeNextLatin Regular for body and UI text. The 60px uppercase headline at weight 300 is the defining typographic gesture — light-weight type that whispers authority rather than shouting it. The fallback stack includes Helvetica and Japanese fonts (Hiragino, Meiryo), reflecting BMW's global presence.
What makes BMW distinctive is its CSS variable-driven theming system. Context-aware variables (`--site-context-highlight-color: #1c69d4`, `--site-context-focus-color: #0653b6`, `--site-context-metainfo-color: #757575`) suggest a design system built for multi-brand, multi-context deployment where colors can be swapped globally. The blue highlight color (`#1c69d4`) is BMW's signature blue — used sparingly for interactive elements and focus states, never decoratively. Zero border-radius was detected — BMW's design is angular, sharp-cornered, and uncompromisingly geometric.
**Key Characteristics:**
- BMWTypeNextLatin Light (weight 300) uppercase for display — whispered authority
- BMW Blue (`#1c69d4`) as singular accent — used only for interactive elements
- Zero border-radius detected — angular, sharp-cornered, industrial geometry
- Dark hero photography + white content sections — showroom lighting rhythm
- CSS variable-driven theming: `--site-context-*` tokens for brand flexibility
- Weight 900 for navigation emphasis — extreme contrast with 300 display
- Tight line-heights (1.15–1.30) throughout — compressed, efficient, German engineering
- Full-bleed automotive photography as primary visual content
## 2. Color Palette & Roles
### Primary Brand
- **Pure White** (`#ffffff`): `--site-context-theme-color`, primary surface, card backgrounds
- **BMW Blue** (`#1c69d4`): `--site-context-highlight-color`, primary interactive accent
- **BMW Focus Blue** (`#0653b6`): `--site-context-focus-color`, keyboard focus and active states
### Neutral Scale
- **Near Black** (`#262626`): Primary text on light surfaces, dark link text
- **Meta Gray** (`#757575`): `--site-context-metainfo-color`, secondary text, metadata
- **Silver** (`#bbbbbb`): Tertiary text, muted links, footer elements
### Interactive States
- All links hover to white (`#ffffff`) — suggesting primarily dark-surface navigation
- Text links use underline: none on hover — clean interaction
### Shadows
- Minimal shadow system — depth through photography and dark/light section contrast
## 3. Typography Rules
### Font Families
- **Display Light**: `BMWTypeNextLatin Light`, fallbacks: `Helvetica, Arial, Hiragino Kaku Gothic ProN, Hiragino Sans, Meiryo`
- **Body / UI**: `BMWTypeNextLatin`, same fallback stack
### Hierarchy
| Role | Font | Size | Weight | Line Height | Notes |
|------|------|------|--------|-------------|-------|
| Display Hero | BMWTypeNextLatin Light | 60px (3.75rem) | 300 | 1.30 (tight) | `text-transform: uppercase` |
| Section Heading | BMWTypeNextLatin | 32px (2.00rem) | 400 | 1.30 (tight) | Major section titles |
| Nav Emphasis | BMWTypeNextLatin | 18px (1.13rem) | 900 | 1.30 (tight) | Navigation bold items |
| Body | BMWTypeNextLatin | 16px (1.00rem) | 400 | 1.15 (tight) | Standard body text |
| Button Bold | BMWTypeNextLatin | 16px (1.00rem) | 700 | 1.20–2.88 | CTA buttons |
| Button | BMWTypeNextLatin | 16px (1.00rem) | 400 | 1.15 (tight) | Standard buttons |
### Principles
- **Light display, heavy navigation**: Weight 300 for hero headlines creates whispered elegance; weight 900 for navigation creates stark authority. This extreme weight contrast (300 vs 900) is the signature typographic tension.
- **Universal uppercase display**: The 60px hero is always uppercase — creating a monumental, architectural quality.
- **Tight everything**: Line-heights from 1.15 to 1.30 across the entire system. Nothing breathes — every line is compressed, efficient, German-engineered.
- **Single font family**: BMWTypeNextLatin handles everything from 60px display to 16px body — unity through one typeface at different weights.
## 4. Component Stylings
### Buttons
- Text: 16px BMWTypeNextLatin, weight 700 for primary, 400 for secondary
- Line-height: 1.15–2.88 (large variation suggests padding-driven sizing)
- Border: white bottom-border on dark surfaces (`1px solid #ffffff`)
- No border-radius — sharp rectangular buttons
### Cards & Containers
- No border-radius — all containers are sharp-cornered rectangles
- White backgrounds on light sections
- Dark backgrounds for hero/feature sections
- No visible borders on most elements
### Navigation
- BMWTypeNextLatin 18px weight 900 for primary nav links
- White text on dark header
- BMW logo 54x54px
- Hover: remains white, text-decoration none
- "Home" text link in header
### Image Treatment
- Full-bleed automotive photography
- Dark cinematic lighting
- Edge-to-edge hero images
- Car photography as primary visual content
## 5. Layout Principles
### Spacing System
- Base unit: 8px
- Scale: 1px, 5px, 8px, 10px, 12px, 15px, 16px, 20px, 24px, 30px, 32px, 40px, 45px, 56px, 60px
### Grid & Container
- Full-width hero photography
- Centered content sections
- Footer: multi-column link grid
### Whitespace Philosophy
- **Showroom pacing**: Dark hero sections with generous padding create the feeling of walking through a showroom where each vehicle is spotlit in its own space.
- **Compressed content**: Body text areas use tight line-heights and compact spacing — information-dense, no waste.
### Border Radius Scale
- **None detected.** BMW uses sharp corners exclusively — every element is a precise rectangle. This is the most angular design system analyzed.
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Photography (Level 0) | Full-bleed dark imagery | Hero backgrounds |
| Flat (Level 1) | White surface, no shadow | Content sections |
| Focus (Accessibility) | BMW Focus Blue (`#0653b6`) | Focus states |
**Shadow Philosophy**: BMW uses virtually no shadows. Depth is created entirely through the contrast between dark photographic sections and white content sections — the automotive lighting does the elevation work.
## 7. Do's and Don'ts
### Do
- Use BMWTypeNextLatin Light (300) uppercase for all display headings
- Keep ALL corners sharp (0px radius) — angular geometry is non-negotiable
- Use BMW Blue (`#1c69d4`) only for interactive elements — never decoratively
- Apply weight 900 for navigation emphasis — the extreme weight contrast is intentional
- Use full-bleed automotive photography for hero sections
- Keep line-heights tight (1.15–1.30) throughout
- Use `--site-context-*` CSS variables for theming
### Don't
- Don't round corners — zero radius is the BMW identity
- Don't use BMW Blue for backgrounds or large surfaces — it's an accent only
- Don't use medium font weights (500–600) — the system uses 300, 400, 700, 900 extremes
- Don't add decorative elements — the photography and typography carry everything
- Don't use relaxed line-heights — BMW text is always compressed
- Don't lighten the dark hero sections — the contrast with white IS the design
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile Small | <375px | Minimum supported |
| Mobile | 375–480px | Single column |
| Mobile Large | 480–640px | Slight adjustments |
| Tablet Small | 640–768px | 2-column begins |
| Tablet | 768–920px | Standard tablet |
| Desktop Small | 920–1024px | Desktop layout begins |
| Desktop | 1024–1280px | Standard desktop |
| Large Desktop | 1280–1440px | Expanded |
| Ultra-wide | 1440–1600px | Maximum layout |
### Collapsing Strategy
- Hero: 60px → scales down, maintains uppercase
- Navigation: horizontal → hamburger
- Photography: full-bleed maintained at all sizes
- Content sections: stack vertically
- Footer: multi-column → stacked
## 9. Agent Prompt Guide
### Quick Color Reference
- Background: Pure White (`#ffffff`)
- Text: Near Black (`#262626`)
- Secondary text: Meta Gray (`#757575`)
- Accent: BMW Blue (`#1c69d4`)
- Focus: BMW Focus Blue (`#0653b6`)
- Muted: Silver (`#bbbbbb`)
### Example Component Prompts
- "Create a hero: full-width dark automotive photography background. Heading at 60px BMWTypeNextLatin Light weight 300, uppercase, line-height 1.30, white text. No border-radius anywhere."
- "Design navigation: dark background. BMWTypeNextLatin 18px weight 900 for links, white text. BMW logo 54x54. Sharp rectangular layout."
- "Build a button: 16px BMWTypeNextLatin weight 700, line-height 1.20. Sharp corners (0px radius). White bottom border on dark surface."
- "Create content section: white background. Heading at 32px weight 400, line-height 1.30, #262626. Body at 16px weight 400, line-height 1.15."
### Iteration Guide
1. Zero border-radius — every corner is sharp, no exceptions
2. Weight extremes: 300 (display), 400 (body), 700 (buttons), 900 (nav)
3. BMW Blue for interactive only — never as background or decoration
4. Photography carries emotion — the UI is pure precision
5. Tight line-heights everywhere — 1.15 to 1.30 is the range

# Design System Inspired by Bugatti
> Category: Automotive
> Hypercar brand. Cinema-black canvas, monochrome austerity, monumental display type.
## 1. Visual Theme & Atmosphere
Bugatti.com does not behave like a website — it behaves like a feature-length car film that a visitor happens to be standing inside. The canvas is pure `#000000`, the only color that appears at rest is white, and the entire page is carried by full-bleed hero video and photography with a single typographic moment laid over the top. There are no cards, no grids, no promotional modules, no newsletter signups, no three-column editorial layouts. It is one continuous cinema-black channel, interrupted only by the cars themselves and a few pill-shaped calls to action that quietly say things like "EXPLORE OUR OPPORTUNITIES" in ALL CAPS monospace.
The single most distinctive move in the entire system is **scale**: the `Bugatti Display` typeface runs at **288px** at hero moments. Two hundred and eighty-eight pixels. That is not a typo — the dembrandt sweep extracted a heading style rendered at an 18rem size, ALL CAPS, line-height 1.0, meant to be read the way you read a brand mark on the front of a Chiron: from across a showroom floor. At 288px the headline is no longer text, it is architecture. The secondary display scale of 60px feels almost miniature next to it, and the 36px mid-display feels like fine print. This typographic hierarchy is the most extreme of any production brand website in this catalog, and it is what gives Bugatti.com its sculptural, couture-showroom presence.
The other signature is **monochromatic austerity**. The entire homepage uses exactly three colors at rest: `#000000`, `#ffffff`, and `#999999` (mid gray for disabled/tertiary states). There is no accent, no brand blue, no hazard color, no commerce orange, no gradient wash. The designers have made a conscious decision that Bugatti's color system should be the car paint itself — the page is a black velvet display stand, and the only color that exists is whatever blue-on-black lacquer the hero vehicle happens to be wearing today. This discipline is the exact opposite of PlayStation's PlayStation Blue or The Verge's Jelly Mint: Bugatti refuses to compete with its own product.
**Key Characteristics:**
- Cinema-black `#000000` canvas for the entire page — no gradients, no tints, no accents
- 288px `Bugatti Display` ALL-CAPS headline — the most extreme display scale in the catalog
- Three-font custom family: `Bugatti Display` (sculptural), `Bugatti Monospace` (UI labels), `Bugatti Text Regular` (body)
- Monochrome-only palette: black, white, and a single `#999999` mid gray for tertiary/disabled
- Pill buttons at `9999px` radius — transparent with a 1px white border, padding `12px 24px`
- Video- and photography-first page — the chrome is almost silent so the product can speak
- Mono UPPERCASE labels with 1.2–1.4px letter-spacing on every CTA, navigation link, and caption
## 2. Color Palette & Roles
### Primary
- **Velvet Black** (`#000000`): The entire canvas. Not near-black, not warm black — the pure HTML `#000`. Bugatti treats this as a display-stand surface, the way a jewelry brand treats a black velvet cloth.
- **Showroom White** (`#ffffff`): All text, all borders, all CTAs. White is the only color that appears at rest on the chrome. It has the weight of typeset print on a matte museum label.
### Secondary & Accent
- **Silver Mist** (`#999999`): The single gray in the system. Used for secondary button borders, disabled states, and the thinnest hairline dividers. Treat this as the "75%-volume" version of white — never a color, just a quieter version of the same voice.
### Surface & Background
- **Velvet Black** (`#000000`): The only surface. There is no secondary surface, no elevated card, no modal backdrop. If something needs to feel "separate", it sits on the same black and is marked with a thin `#999999` border — no color change.
### Neutrals & Text
- **Primary Text** (`#ffffff`): All headlines, body copy, button labels, and navigation items.
- **Tertiary Text** (`#999999`): Disclaimer text, placeholder labels, and the faintest supporting metadata. Used sparingly — Bugatti prefers to hide secondary content rather than dim it.
### Semantic & Accent
- **Tailwind Ring Leak** (`rgba(59, 130, 246, 0.5)`): A Tailwind default `--tw-ring-color` leaks into the extracted tokens from the build system — this is **not** part of the Bugatti brand palette. Ignore it. If a real focus state is needed, use a 1px `#ffffff` ring instead.
### Gradient System
None. There are zero decorative gradients on Bugatti.com. The only "gradient" on the page is whatever natural light gradient exists inside the hero video of the car itself. The brand refuses to apply any chrome gradient that could compete with the atmospheric lighting of the product photography.
## 3. Typography Rules
### Font Family
- **Bugatti Display** — fallback: `ui-sans-serif`, `system-ui`. A proprietary custom display typeface used only at very large sizes for hero and mid-display headlines. Designed to be read at architectural scale — at 288px, its geometry doubles as a visual element, not just text. The face carries a faint hint of early-20th-century Grand Prix typography (the period when Ettore Bugatti was racing) without ever becoming nostalgic.
- **Bugatti Monospace** — fallback: `ui-sans-serif`, `system-ui`. A custom monospaced face reserved for every UI label on the site. It handles all navigation links, all button labels, all captions, and all UPPERCASE metadata. The strict mono tracking (1.2–1.4px letter-spacing on all usages) gives the UI the appearance of a technical dossier or dashboard telemetry printout — appropriate for a company that builds 1600-horsepower hypercars.
- **Bugatti Text Regular** — fallback: `ui-sans-serif`, `system-ui`. The body copy workhorse, used for the rare paragraph and inline reading text. Weights and styles are restrained — this font exists to be invisible when the display type is shouting and the monospace is whispering.
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|---|---|---|---|---|---|---|
| Hero Display (Monumental) | Bugatti Display | 288px / 18.00rem | 400 | 1.00 | — | ALL CAPS — the largest display scale in this catalog, architectural in presence |
| Mid Display (Feature) | Bugatti Display | 60px / 3.75rem | 400 | 1.00 | 1.4px | Feature-panel headlines, ALL CAPS optional |
| Mid Display (Subfeature) | Bugatti Display | 60px / 3.75rem | 400 | 1.00 | — | Secondary feature headlines |
| Section Heading | Bugatti Display | 36px / 2.25rem | 400 | 1.11 | — | Section-level title |
| Monumental Mono Headline | Bugatti Monospace | 60px / 3.75rem | 400 | 1.00 | — | UPPERCASE — reserved for technical/section labels at hero scale |
| Body Small (Display) | Bugatti Display | 16px / 1.00rem | 400 | 1.50 | — | Display face used sparingly at body size for marketing copy |
| Lead Body | Bugatti Text Regular | 20px / 1.25rem | 400 | 1.40 | — | Paragraph lead |
| Body Regular | Bugatti Text Regular | 16px / 1.00rem | 400 | 1.50 | — | Standard reading body |

### Principles
- **Bugatti Display is a sculpture, not a font.** If you find yourself typesetting body copy or a button in Bugatti Display, you're using the wrong tool. Reserve this face for headlines at **36px minimum**, ideally 60px+, and at least once per page use it at 200px+ to create the monumental effect the brand is built around.
- **Bugatti Monospace owns the UI.** Every navigation link, every button, every caption, every eyebrow runs in Bugatti Monospace — usually UPPERCASE with 1.2–1.4px tracking. This mono-caps discipline is what makes the UI read like a Grand Prix telemetry panel rather than a luxury shopping cart.
- **Bugatti Text Regular is invisible.** It appears only in short paragraphs and inline reading copy, usually at 14–20px. It is never used for labels, buttons, or display.
- **There is no bold.** Every weight in the extracted tokens is regular (400). Bugatti does not use weight for hierarchy — it uses scale. When you need emphasis, make the type bigger, not heavier.
- **Tracking has two registers.** Mono caps always carry 1.2–1.4px letter-spacing. Display type at 60px+ sometimes carries 1.4px tracking at the hero scale. Body type has no tracking.
- **Line-height is brutally tight at display.** Every Bugatti Display usage runs at line-height 1.00 or 1.11. Headlines touch each other when they wrap — that's the design. Do not relax the leading.
### Note on Font Substitutes
The 1.00 line-height and 288px display scale both assume the **proprietary Bugatti Display face**, which is drawn with compact vertical metrics purpose-built for architectural scale. If you substitute with open-source extended geometric displays like **Unbounded**, **Big Shoulders Display**, or **Archivo Black**, make two adjustments: (1) **loosen line-height to ~1.05–1.10** to prevent ascender collisions, and (2) **cap the maximum display size at ~104–128px** on most viewports — these substitutes have wider horizontal metrics than Bugatti Display, so a 288px monumental headline will wrap across 4+ lines and overwhelm the layout. Reserve the 200px+ scale only for single-word monumental moments (e.g., "BUGATTI" alone). Bugatti Monospace substitutes (Space Mono, JetBrains Mono) and Bugatti Text Regular substitutes (Inter, DM Sans) work at the token values without adjustment.
## 4. Component Stylings
### Buttons
**Primary — White Outlined Pill**
- Background: transparent
- Text: `#ffffff`, Bugatti Monospace 14px / 400 / 1.4px tracking, UPPERCASE
- Border: `1px solid #ffffff`
- Border radius: `9999px` — full pill
- Padding: `12px 24px`
- Outline: `rgb(255, 255, 255) none 0px` at rest
- Hover: likely background fill to `#ffffff` with black text, or a subtle opacity dim (the extracted token set did not capture a bespoke hover — treat this as a safe assumption since the default Bugatti interaction is restraint)
- Active: opacity drop to ~0.7
- Focus: use a 1px `#ffffff` outer ring via `box-shadow: 0 0 0 1px #ffffff, 0 0 0 2px #000000` for contrast
- Transition: 200–300ms ease on background/color — quiet, never bouncy
**Secondary — Gray Rounded Button**
- Background: transparent
- Text: `#ffffff`, Bugatti Monospace 12px / 400 / 1.2px tracking, UPPERCASE
- Border: `1px solid #999999` (Silver Mist)
- Border radius: `6px` — subtle corner, the only non-pill non-zero radius in the system
- Padding: `6px 12px`
- Hover: border transitions to `#ffffff`, text stays white
- Active: opacity 0.7
- Used for compact utility buttons (menu toggles, closed-dialog buttons)
**Ghost — Unbordered Link Button**
- Background: transparent
- Text: `#ffffff`, Bugatti Monospace 12px / 400 — plain or UPPERCASE
- No border, no padding beyond inline
- Used in the footer and tertiary nav
### Cards & Containers
- **There are no cards.** Bugatti.com has no card component. The entire page is a sequence of full-bleed media blocks with a headline and optional CTA overlaid — more akin to a film chapter than a card grid.
- The closest thing to a "container" is the rare bordered section that uses a `1px solid #999999` frame, a `6px` border radius, and `#000000` interior. These are reserved for cookie-consent notices and modal-style dialogues, not editorial content.
- Hover state on media blocks: none. The video plays, the CTA becomes clickable, and that is the entire interaction vocabulary.
### Inputs & Forms
- The extracted tokens captured **zero input styles** (`⚠ Inputs: 0 styles`). This is because Bugatti.com has essentially no forms on the homepage — no newsletter signup, no search bar, no contact form, no email capture. When forms do appear (on deeper pages), apply these defaults consistent with the rest of the system:
- **Default**: `#000000` background, `1px solid #999999` border, `6px` radius, `#ffffff` text in Bugatti Text Regular 16px, placeholder `#999999`.
- **Focus**: border transitions to `#ffffff`, no glow — the border change IS the focus signal.
- **Error**: border stays white; add a `#999999` inline message below. Bugatti does not use red error colors — it stays in the monochrome palette.
- **Transition**: ~250ms ease on border-color.
### Navigation
- **Top nav**: black (`#000000`) thin strip with the Bugatti "EB" monogram or full "BUGATTI" wordmark centered, a hamburger "MENU" link left, and a "STORE" link right. Both nav links are Bugatti Monospace 14px UPPERCASE with 1.4px tracking.
- **Logo**: 128×29px at desktop scale — smaller than nearly every other brand in this catalog. Bugatti does not need to shout its name.
- **Hover on nav links**: color stays `#ffffff` — the hover signal is a subtle text-decoration underline or an opacity shift to ~0.75. No color change.
- **Mobile**: the full nav collapses to just three elements — "MENU", the wordmark, and "STORE" — which is basically the desktop layout minus the separator spacing.
- **Sticky behavior**: the nav is pinned at the top on scroll and stays black-on-black. When it overlaps a dark video, it becomes nearly invisible, which is by design.
### Image & Video Treatment
- **Aspect ratios**: 16:9 and 21:9 for hero video, 4:3 for mid-feature photography, 1:1 for rare portrait shots.
- **Corners**: rare — most media is full-bleed with zero border radius. When radius appears, it's `6px`.
- **Full-bleed**: yes, always. The hero video fills the viewport. Secondary feature video fills 100% of the section width.
- **Captions**: Bugatti Monospace 12px UPPERCASE in `#ffffff` at ~1.2px tracking, placed below the media or in the lower-left corner.
- **Hover**: no zoom, no scale, no scrim. The video plays, that is the hover state.
- **Lazy loading**: `loading="lazy"` on every image below the fold; hero video is preloaded.
### Atmospheric Overlay
- When type sits over photography or video that might threaten legibility, Bugatti uses a subtle `rgba(0, 0, 0, 0.4)` linear gradient from bottom (40% black) to top (transparent) — the only "shadow-like" effect in the system. It's a vignette, not a drop shadow.
## 5. Layout Principles
### Spacing System
- **Base unit**: 8px.
- **Scale** (from tokens): 4, 6, 12, 36, 48, 64px. Six values. **Six.** This is one of the smallest spacing scales of any major brand site — Bugatti uses a handful of discrete gaps and refuses to invent in-between values.
- **Section padding**: typically 48–64px vertical. Hero panels are full-viewport-height, which bypasses the scale entirely.
- **Button padding**: 6px 12px (compact) or 12px 24px (primary). Nothing else.
- **Inline spacing**: 4–12px between stacked labels; the big jump to 36/48/64 happens between content blocks.
### Grid & Container
- **Max width**: 1720px (dembrandt detected breakpoints up to 1720). The site scales to ultra-wide for luxury showroom displays and wide cinema monitors.
- **Column patterns**: there is essentially no multi-column grid on the homepage — it is a stack of single full-width blocks. When deeper pages need columns (configurator, atelier, technical specs), they use a 12-column Tailwind-based grid.
- **Outer padding**: minimal. Most sections bleed to the viewport edge, with padding only applied to the overlaid text and CTA block (typically 48–64px from the bottom-center).
### Whitespace Philosophy
Bugatti's whitespace philosophy is **cinematic negative space** — the page is 90% empty even when content is present, because the content is usually a video or photograph of a single car. The rhythm is: full-bleed media → monumental headline → single pill CTA → scroll → next full-bleed media. There is no "information density" anywhere. The page breathes the way a museum breathes, with each exhibit getting its own silent room.
### Border Radius Scale
- **0** — default for all media and the hero canvas
- **6px** — secondary rounded buttons, bordered frames, small utility containers
- **9999px** — primary pill buttons
Three values. No `12px`, no `24px`, no `20px`. Bugatti's radius system is the most restrained of any site in this catalog — the brand has made an active decision that "slightly rounded rectangle" is a vulgar shape, and committed to either true rectangle or true pill.
## 6. Depth & Elevation
| Level | Treatment | Use |
|---|---|---|
| 0 | No shadow, no border | Default text and media on `#000000` |
| 1 | `1px solid #999999` | Secondary containers, cookie-style dialogs |
| 2 | `1px solid #ffffff` | Primary button outline, active state indicators |
| 3 | Bottom-to-top `rgba(0, 0, 0, 0.4) → transparent` vignette | Text-legibility gradient when type sits over video |
**That is the entire depth system.** There are 1 shadows in the extracted token set (zero meaningful `box-shadow` values — just a placeholder). Bugatti does not use drop shadows. It does not use elevation rings. It does not use glowing focus states. Depth is implied by the 1px hairline of a border or the presence of a vignette gradient — nothing more.
### Decorative Depth
None. Zero gradients (except the subtle text-legibility vignette), zero blurs, zero glows, zero atmospheric effects. The decorative depth of Bugatti's site comes entirely from the lighting baked into the product photography. The chrome does not compete.
## 7. Do's and Don'ts
### Do
- **Do** keep the entire canvas `#000000`. No off-black, no near-black, no warm black. Bugatti is pure black.
- **Do** use Bugatti Display at architectural scale — minimum 36px, ideally 60px+, and once per page land a monumental 200px+ headline.
- **Do** use Bugatti Monospace UPPERCASE with 1.2–1.4px tracking for every button, link, nav item, and caption.
- **Do** use only white text at rest. `#999999` is only for disabled, tertiary, and thin borders.
- **Do** use 9999px border radius for primary buttons — full pill, thin 1px white outline, transparent fill.
- **Do** use full-bleed video and photography for every hero section. The product is the UI.
- **Do** maintain line-height 1.00–1.11 on display headlines. Tight leading is the architecture.
- **Do** treat whitespace like cinematic negative space — give every block its own silent room.
### Don't
- **Don't** introduce accent colors. No blue, no red, no commerce orange, no hover cyan, no warning red. The palette is black, white, and one gray.
- **Don't** use bold weights for hierarchy. Scale is the only hierarchy device — make it bigger, not heavier.
- **Don't** use drop shadows on any element. Bugatti has no `box-shadow` in its chrome.
- **Don't** use cards or elevated surfaces. Bugatti has no card component.
- **Don't** use rounded rectangles between 6px and 9999px. The radius system is rectangle, slightly-rounded utility, or full pill — nothing in between.
- **Don't** use Bugatti Display for body, buttons, or UI labels. Reserve it for headlines at 36px+.
- **Don't** use Bugatti Monospace in lowercase for primary UI. Buttons and nav links are always ALL CAPS.
- **Don't** add gradients, glows, blurs, or glassmorphism anywhere. The chrome is silent.
- **Don't** put text over photography without a `rgba(0, 0, 0, 0.4)` bottom-up vignette if legibility is at risk.
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|---|---|---|
| Mobile | <640px | Single column, hamburger "MENU", hero video locked to 9:16 or 16:9, hero headline scales to ~48–72px |
| Small Tablet | 640–767px | Still single column, padding opens slightly, typography scales up |
| Tablet | 768–1023px | Still single column for content, nav expands to include wordmark, headline scales to ~120px |
| Small Desktop | 1024–1279px | Full desktop nav, headline scales to ~200px |
| Desktop | 1280–1535px | Full layout, headline at 240–260px |
| Large Desktop | 1536–1719px | Max headline scale (288px), ultra-wide hero video |
| Ultra-Wide | ≥1720px | Container caps, hero video locks at 21:9 or wider, everything else stays proportional |
The dembrandt sweep detected 6 breakpoints (1720 → 1536 → 1280 → 1024 → 768 → 640). This is a narrower responsive set than PlayStation's 30 — Bugatti tunes for six clean thresholds rather than micro-adjusting every device boundary. The brand's assumption is that its visitors are either on a high-end laptop, a desktop monitor, or a phone, and the site doesn't need to fuss over everything in between.
### Touch Targets
- Primary pill buttons are `12px 24px` padded with 14px text — approximately 38–42px tall. **This falls slightly below WCAG AAA 44px recommendations**. For derivative work, bump vertical padding to 14–16px to hit 44px+.
- Secondary buttons at `6px 12px` padding are about 28–32px tall — definitely below touch-target minimums. Use these only on desktop pointer contexts.
- Navigation links have no explicit padding — the tap area is the text box, which at 14px is too small. Add `12–14px` vertical padding on mobile to make them touchable.
### Collapsing Strategy
- **Nav**: desktop shows `MENU / BUGATTI wordmark / STORE`. Mobile keeps the same layout — there is no drawer, because there are only three items.
- **Grid**: no grid to collapse. The page is already single-column at every breakpoint.
- **Spacing**: section padding tightens from 64 → 48 → 36 → 12px as viewport narrows.
- **Type**: Bugatti Display scales from 288px → 200px → 120px → 60px → 48px as viewport narrows. The scale curve is aggressive — losing 240px between the max and mobile hero.
- **Video**: art-direction swap between 21:9 desktop and 16:9 or 9:16 mobile hero cuts.
### Image & Video Behavior
- Hero video uses adaptive bitrate streaming and `poster=` fallback.
- Below-the-fold media uses `loading="lazy"` with `srcset` art direction.
- Bugatti serves high-density imagery through `imgix` — you'll see `bugatti.imgix.net` URLs with transformation parameters.
## 9. Agent Prompt Guide
### Quick Color Reference
- **Primary Canvas**: "Velvet Black (`#000000`)"
- **Primary Text**: "Showroom White (`#ffffff`)"
- **Secondary Text / Disabled / Hairline Border**: "Silver Mist (`#999999`)"
- **Accent**: None. Do not add one.
- **Hover Signal**: Opacity shift or border-color shift — no color change
### Example Component Prompts
1. *"Create a monumental hero headline using Bugatti Display at 288px, ALL CAPS, `#ffffff` text on a pure `#000000` canvas, line-height 1.0, no letter-spacing. Place a full-bleed 21:9 hero video behind it with a `rgba(0, 0, 0, 0.4) → transparent` bottom-up vignette for legibility."*
2. *"Design a primary pill CTA button: transparent background, 1px solid `#ffffff` border, `9999px` border radius, 12px × 24px padding, Bugatti Monospace 14px / 400 / 1.4px letter-spacing UPPERCASE label in `#ffffff`. Hover state fills the background white with black text, 250ms ease."*
3. *"Build a navigation bar: pure `#000000` background, `MENU` link left, centered `BUGATTI` wordmark (128×29px), `STORE` link right. All links in Bugatti Monospace 14px UPPERCASE with 1.4px letter-spacing in `#ffffff`. No dividers, no hover color — just a slight opacity dim on hover."*
4. *"Create a mid-feature section heading: Bugatti Display 60px ALL CAPS in `#ffffff`, line-height 1.0, centered over a full-bleed photograph. Place a single primary pill CTA 48–64px below the headline."*
5. *"Design a secondary utility button for a cookie dialog: transparent background, 1px solid `#999999` border, 6px border radius, 6px × 12px padding, Bugatti Monospace 12px / 400 / 1.2px tracking UPPERCASE label in `#ffffff`."*
### Iteration Guide
When refining existing screens generated with this design system:
1. **Audit the canvas.** If the background isn't pure `#000000`, change it. Bugatti does not tolerate off-black.
2. **Audit the palette.** Any color that isn't `#000000`, `#ffffff`, or `#999999` is drift. Remove it — that includes ALL accent colors, including common defaults like `#0070cc` Tailwind blue.
3. **Audit display scale.** If the largest headline on a page is smaller than 60px, it's under-scaled. Bugatti's minimum "monumental moment" is 60px; the maximum is 288px. Aim for the upper half.
4. **Audit mono-caps discipline.** Every button, every nav link, every caption, every CTA should be Bugatti Monospace UPPERCASE with 1.2–1.4px letter-spacing. If you see sentence case or mixed case on a button, that's drift.
5. **Audit shadows and gradients.** Strip every `box-shadow`. Strip every gradient except the one legibility vignette over video. Bugatti's chrome is silent.
6. **Audit radius.** Every container should land on `0`, `6px`, or `9999px`. If you see `12px`, `16px`, `20px`, `24px`, correct to the nearest Bugatti value (almost always `6px` or `9999px`).
7. **Audit type weight.** All weights should be 400. If you see `bold` or `700` anywhere, change it. Scale, not weight, is the hierarchy.
8. **Audit whitespace.** If a section feels cramped, add 48–64px. If it feels airy, leave it — Bugatti's negative space is a feature.
9. **Audit product presence.** Every hero section should have a vehicle — video or photograph — as the primary visual. The chrome should feel like it's framing the car, not competing with it.

> Cozy cafe-inspired interface with warm tones, soft typography, and clean layouts for a relaxed browsing experience.
## 1. Visual Theme & Atmosphere
Cozy cafe-inspired interface with warm tones, soft typography, and clean layouts for a relaxed browsing experience.
- **Visual style:** minimal, clean
- **Color stance:** primary, neutral, success, warning, danger
- **Design intent:** Keep outputs recognizable to this style family while preserving usability and readability.
## 2. Color
- **Primary:** `#5D4432` — Token from style foundations.
- **Secondary:** `#E9E3DD` — Token from style foundations.
- **Success:** `#16A34A` — Token from style foundations.
- **Warning:** `#D97706` — Token from style foundations.
- **Danger:** `#DC2626` — Token from style foundations.
- **Surface:** `#F9F7F5` — Token from style foundations.
- **Text:** `#3E2B1E` — Token from style foundations.
- **Neutral:** `#F9F7F5` — Derived from the surface token for official format compatibility.
- Favor Primary (#5D4432) for CTA emphasis.
- Use Surface (#F9F7F5) for large backgrounds and cards.
- Keep body copy on Text (#3E2B1E) for legibility.
## 3. Typography
- **Scale:** desktop-first expressive scale
- **Families:** primary=Poppins, display=Poppins, mono=JetBrains Mono
- **Weights:** 100, 200, 300, 400, 500, 600, 700, 800, 900
- Headings should carry the style personality; body text should optimize scanability and contrast.
## 4. Spacing & Grid
- **Spacing scale:** 2/4/8/12/16/24/32/48
- Keep vertical rhythm consistent across sections and components.
- Align columns and modules to a predictable grid; avoid ad-hoc offsets.
## 5. Layout & Composition
- Prefer clear content blocks with consistent internal padding.
- Keep hierarchy obvious: headline → support text → primary action.
- Use whitespace to separate concerns before adding borders or shadows.
## 6. Components
- Buttons: primary action uses `#5D4432`; secondary actions stay neutral.
- Inputs: strong focus-visible states, clear labels, and predictable error messaging.
- Cards/sections: use consistent radii, spacing, and elevation strategy across the page.
## 7. Motion & Interaction
- Use subtle transitions that emphasize Primary (#5D4432) as the interaction signal.
- Default to short, purposeful transitions (150–250ms) with stable easing.
- Ensure hover, focus-visible, active, disabled, and loading states are explicit.
## 8. Voice & Brand
- Tone should reflect the visual style: concise, confident, and product-specific.
- Keep microcopy action-oriented and avoid generic filler language.
- Preserve the style identity in headlines while keeping UI labels literal and clear.
## 9. Anti-patterns
- Do not introduce off-palette colors when an existing token can solve the problem.
- Do not flatten hierarchy by using the same type size/weight for all text.
- Do not add decorative effects that reduce readability or accessibility.
- Do not mix unrelated visual metaphors in the same interface.

# Design System Inspired by Cal.com
> Category: Productivity & SaaS
> Open-source scheduling. Clean neutral UI, developer-oriented simplicity.
## 1. Visual Theme & Atmosphere
Cal.com's website is a masterclass in monochromatic restraint — a grayscale world where boldness comes not from color but from the sheer confidence of black text on white space. Inspired by Uber's minimal aesthetic, the palette is deliberately stripped of hue: near-black headings (`#242424`), mid-gray secondary text (`#898989`), and pure white surfaces. Color is treated as a foreign substance — when it appears (a rare blue link, a green trust badge), it feels like a controlled accent in an otherwise black-and-white photograph.
Cal Sans, the brand's custom geometric display typeface designed by Mark Davis, is the visual centerpiece. Letters are intentionally spaced extremely close at large sizes, creating dense, architectural headlines that feel like they're carved into the page. At 64px and 48px, Cal Sans headings sit at weight 600 with a tight 1.10 line-height — confident, compressed, and immediately recognizable. For body text, the system switches to Inter, providing "rock-solid" readability that complements Cal Sans's display personality. The typography pairing creates a clear division: Cal Sans speaks, Inter explains.
The elevation system is notably sophisticated for a minimal site — 11 shadow definitions create a nuanced depth hierarchy using multi-layered shadows that combine ring borders (`0px 0px 0px 1px`), soft diffused shadows, and inset highlights. This shadow-first approach to depth (rather than border-first) gives surfaces a subtle three-dimensionality that feels modern and polished. Built on Framer with a border-radius scale from 2px to 9999px (pill), Cal.com balances geometric precision with soft, rounded interactive elements.
**Key Characteristics:**
- Purely grayscale brand palette — no brand colors, boldness through monochrome
- Cal Sans custom geometric display font with extremely tight default letter-spacing
- Multi-layered shadow system (11 definitions) with ring borders + diffused shadows + inset highlights
- Cal Sans for headings, Inter for body — clean typographic division
- Wide border-radius scale from 2px to 9999px (pill) — versatile rounding
- White canvas with near-black (#242424) text — maximum contrast, zero decoration
- Product screenshots as primary visual content — the scheduling UI sells itself
- Built on Framer platform
## 2. Color Palette & Roles
### Primary
- **Charcoal** (`#242424`): Primary heading and button text — Cal.com's signature near-black, warmer than pure black
- **Midnight** (`#111111`): Deepest text/overlay color — used at 50% opacity for subtle overlays
- **White** (`#ffffff`): Primary background and surface — the dominant canvas
### Secondary & Accent
- **Link Blue** (`#0099ff`): In-text links with underline decoration — the only blue in the system, reserved strictly for hyperlinks
- **Focus Ring** (`#3b82f6` at 50% opacity): Keyboard focus indicator — accessibility-only, invisible in normal interaction
- **Default Link** (`#0000ee`): Browser-default link color on some elements — unmodified, signaling openness
### Surface & Background
- **Pure White** (`#ffffff`): Primary page background and card surfaces
- **Light Gray** (approx `#f5f5f5`): Subtle section differentiation — barely visible tint
- **Mid Gray** (`#898989`): Secondary text, descriptions, and muted labels
### Neutrals & Text
- **Charcoal** (`#242424`): Headlines, buttons, primary UI text
- **Midnight** (`#111111`): Deep black for high-contrast links and nav text
- **Mid Gray** (`#898989`): Descriptions, secondary labels, muted content
- **Pure Black** (`#000000`): Certain link text elements
- **Border Gray** (approx `rgba(34, 42, 53, 0.08–0.10)`): Shadow-based borders using ring shadows instead of CSS borders
### Semantic & Accent
- Cal.com is deliberately colorless for brand elements — "a grayscale brand to emphasise on boldness and professionalism"
- Product UI screenshots show color (blues, greens in the scheduling interface), but the marketing site itself stays monochrome
- The philosophy mirrors Uber's approach: let the content carry color, the frame stays neutral
### Gradient System
- No gradients on the marketing site — the design is fully flat and monochrome
- Depth is achieved entirely through shadows, not color transitions
## 3. Typography Rules
### Font Family
- **Display**: `Cal Sans` — custom geometric sans-serif by Mark Davis. Open-source, available on Google Fonts and GitHub. Extremely tight default letter-spacing designed for large headlines. Has 6 character variants (Cc, j, t, u, 0, 1)
- **Body**: `Inter` — "rock-solid" standard body font. Fallback: `Inter Placeholder`
- **UI Light**: `Cal Sans UI Variable Light` — light-weight variant (300) for softer UI text with -0.2px letter-spacing
- **UI Medium**: `Cal Sans UI Medium` — medium-weight variant (500) for emphasized captions
- **Mono**: `Roboto Mono` — for code blocks and technical content
- **Tertiary**: `Matter Regular` / `Matter SemiBold` / `Matter Medium` — additional body fonts for specific contexts
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|

### Principles
- **Cal Sans at large, Inter at small**: Cal Sans is exclusively for headings and display — never for body text. The system enforces this division strictly
- **Tight by default, space when small**: Cal Sans letters are "intentionally spaced to be extremely close" at large sizes. At 20px and below, positive letter-spacing (+0.2px) must be applied to prevent cramming
- **Weight 300 body variant**: Cal Sans UI Variable Light at 300 weight creates an elegant, airy body text that contrasts with the dense 600-weight headlines
- **Weight 600 dominance**: Nearly all Cal Sans usage is at weight 600 (semi-bold) — the font was designed to perform at this weight
- **Negative tracking on light text**: Cal Sans UI Light uses -0.2px to -0.28px letter-spacing, subtly tightening the already-compact letterforms
## 4. Component Stylings
### Buttons
- **Dark Primary**: `#242424` (or `#1e1f23`) background, white text, 6–8px radius. Hover: opacity reduction to 0.7. The signature CTA — maximally dark on white
- **White/Ghost**: White background with shadow-ring border, dark text. Uses the multi-layered shadow system for subtle elevation
- **Pill**: 9999px radius for rounded pill-shaped actions and badges
- **Compact**: 4px padding, small text — utility actions within product UI
- **Inset highlight**: Some buttons feature `rgba(255, 255, 255, 0.15) 0px 2px 0px inset` — a subtle inner-top highlight creating a 3D pressed effect
### Cards & Containers
- **Shadow Card**: White background, multi-layered shadow — `rgba(19, 19, 22, 0.7) 0px 1px 5px -4px, rgba(34, 42, 53, 0.08) 0px 0px 0px 1px, rgba(34, 42, 53, 0.05) 0px 4px 8px 0px`. The ring shadow (0px 0px 0px 1px) acts as a shadow-border
- **Product UI Cards**: Screenshots of the scheduling interface displayed in card containers with shadow elevation
- **Radius**: 8px for standard cards, 12px for larger containers, 16px for prominent sections
- **Hover**: Likely subtle shadow deepening or scale transform
### Inputs & Forms
- **Select dropdown**: White background, `#000000` text, 1px solid `rgb(118, 118, 118)` border
- **Focus**: Uses Framer's focus outline system (`--framer-focus-outline`)
- **Text input**: 8px radius, standard border treatment
- **Minimal form presence**: The marketing site prioritizes CTA buttons over complex forms
### Navigation
- **Top nav**: White/transparent background, Cal Sans links at near-black
- **Nav text**: `#111111` (Midnight) for primary links, `#000000` for emphasis
- **CTA button**: Dark Primary in the nav — high contrast call-to-action
- **Mobile**: Collapses to hamburger with simplified navigation
- **Sticky**: Fixed on scroll
### Image Treatment
- **Product screenshots**: Large scheduling UI screenshots — the product is the primary visual
- **Trust logos**: Grayscale company logos in a horizontal trust bar
- **Aspect ratios**: Wide landscape for product UI screenshots
- **No decorative imagery**: No illustrations, photos, or abstract graphics — pure product + typography
## 5. Layout Principles
### Spacing System
- **Base unit**: 8px
- **Scale**: 1px, 2px, 3px, 4px, 6px, 8px, 12px, 16px, 20px, 24px, 28px, 80px, 96px
- **Section padding**: 80px–96px vertical between major sections (generous)
- **Card padding**: 12px–24px internal
- **Component gaps**: 4px–8px between related elements
- **Notable jump**: From 28px to 80px — a deliberate gap emphasizing the section-level spacing tier
### Grid & Container
- **Max width**: ~1200px content container, centered
- **Column patterns**: Full-width hero, centered text blocks, 2-3 column feature grids
- **Feature showcase**: Product screenshots flanked by description text
- **Breakpoints**: 98px, 640px, 768px, 810px, 1024px, 1199px — Framer-generated
### Whitespace Philosophy
- **Lavish section spacing**: 80px–96px between sections creates a breathable, premium feel
- **Product-first content**: Screenshots dominate the visual space — minimal surrounding decoration
- **Centered headlines**: Cal Sans headings centered with generous margins above and below
### Border Radius Scale
- **2px**: Subtle rounding on inline elements
- **4px**: Small UI components
- **6px–7px**: Buttons, small cards, images
- **8px**: Standard interactive elements — buttons, inputs, images
- **12px**: Medium containers — links, larger cards, images
- **16px**: Large section containers
- **29px**: Special rounded elements
- **100px**: Large rounding — nearly circular on small elements
- **1000px**: Very large rounding
- **9999px**: Full pill shape — badges, links
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Level 0 (Flat) | No shadow | Page canvas, basic text containers |
| Level 1 (Inset) | `rgba(0,0,0,0.16) 0px 1px 1.9px 0px inset` | Pressed/recessed elements, input wells |
| Level 2 (Ring + Soft) | `rgba(19,19,22,0.7) 0px 1px 5px -4px, rgba(34,42,53,0.08) 0px 0px 0px 1px, rgba(34,42,53,0.05) 0px 4px 8px` | Cards, containers — the workhorse shadow |
| Level 3 (Ring + Soft Alt) | `rgba(36,36,36,0.7) 0px 1px 5px -4px, rgba(36,36,36,0.05) 0px 4px 8px` | Alt card elevation without ring border |
| Level 4 (Inset Highlight) | `rgba(255,255,255,0.15) 0px 2px 0px inset` or `rgb(255,255,255) 0px 2px 0px inset` | Button inner highlight — 3D pressed effect |
| Level 5 (Soft Only) | `rgba(34,42,53,0.05) 0px 4px 8px` | Subtle ambient shadow |
### Shadow Philosophy
Cal.com's shadow system is the most sophisticated element of the design — 11 shadow definitions using a multi-layered compositing technique:
- **Ring borders**: `0px 0px 0px 1px` shadows act as borders, avoiding CSS `border` entirely. This creates hairline containment without affecting layout
- **Diffused soft shadows**: `0px 4px 8px` at 5% opacity add gentle ambient depth
- **Sharp contact shadows**: `0px 1px 5px -4px` at 70% opacity create tight bottom-edge shadows for grounding
- **Inset highlights**: White inset shadows at the top of buttons create a subtle 3D bevel
- Shadows are composed in comma-separated stacks — each surface gets 2-3 layered shadow definitions working together
### Decorative Depth
- No gradients or glow effects
- All depth comes from the sophisticated shadow compositing system
- The overall effect is subtle but precise — surfaces feel like physical cards sitting on a table
## 7. Do's and Don'ts
### Do
- Use Cal Sans exclusively for headings (24px+) and never for body text — it's a display font with tight default spacing
- Apply positive letter-spacing (+0.2px) when using Cal Sans below 24px — the font cramps at small sizes without it
- Maintain the grayscale palette — boldness comes from contrast, not color
- Use the multi-layered shadow system for card elevation — ring shadow + diffused shadow + contact shadow
- Keep backgrounds pure white — the monochrome philosophy requires a clean canvas
- Use Inter for all body text at weight 300–600 — it's the reliable counterpart to Cal Sans's display personality
- Let product screenshots be the visual content — no illustrations, no decorative graphics
- Apply generous section spacing (80px–96px) — the breathing room is essential to the premium feel
### Don't
- Use Cal Sans for body text or text below 16px — it wasn't designed for extended reading
- Add brand colors — Cal.com is intentionally grayscale, color is reserved for links and UI states only
- Use CSS borders when shadows can achieve the same containment — the ring-shadow technique is the system's approach
- Apply negative letter-spacing to Cal Sans at small sizes — it needs positive spacing (+0.2px) below 24px
- Create heavy, dark shadows — Cal.com's shadows are subtle (5% opacity diffused) with sharp contact edges
- Use illustrations, abstract graphics, or decorative elements — the visual language is typography + product UI only
- Mix Cal Sans weights — the font is designed for weight 600, other weights break the intended character
- Reduce section spacing below 48px — the generous whitespace is core to the premium monochrome aesthetic
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | <640px | Single column, hero text ~36px, stacked features, hamburger nav |
| Tablet Small | 640px–768px | 2-column begins for some elements |
| Tablet | 768px–810px | Layout adjustments, fuller grid |
| Tablet Large | 810px–1024px | Multi-column feature grids |
| Desktop | 1024px–1199px | Full layout, expanded navigation |
| Large Desktop | >1199px | Max-width container, centered content |
### Touch Targets
- Buttons: 8px radius with comfortable padding (10px+ vertical)
- Nav links: Dark text with adequate spacing
- Mobile CTAs: Full-width dark buttons for easy thumb access
- Pill badges: 9999px radius creates large, tappable targets
### Collapsing Strategy
- **Navigation**: Full horizontal nav → hamburger on mobile
- **Hero**: 64px Cal Sans display → ~36px on mobile
- **Feature grids**: Multi-column → 2-column → single stacked column
- **Product screenshots**: Scale within containers, maintaining aspect ratios
- **Section spacing**: Reduces from 80px–96px to ~48px on mobile
### Image Behavior
- Product screenshots scale responsively
- Trust logos reflow to multi-row grid on mobile
- No art direction changes — same compositions at all sizes
- Images use 7px–12px border-radius for consistent rounded corners
## 9. Agent Prompt Guide
### Quick Color Reference
- Primary Text: Charcoal (`#242424`)
- Deep Text: Midnight (`#111111`)
- Secondary Text: Mid Gray (`#898989`)
- Background: Pure White (`#ffffff`)
- Link: Link Blue (`#0099ff`)
- CTA Button: Charcoal (`#242424`) bg, white text
- Shadow Border: `rgba(34, 42, 53, 0.08)` ring
### Example Component Prompts
- "Create a hero section with white background, 64px Cal Sans heading at weight 600, line-height 1.10, #242424 text, centered layout with a dark CTA button (#242424, 8px radius, white text)"
- "Design a scheduling card with white background, multi-layered shadow (0px 1px 5px -4px rgba(19,19,22,0.7), 0px 0px 0px 1px rgba(34,42,53,0.08), 0px 4px 8px rgba(34,42,53,0.05)), 12px radius"
- "Build a navigation bar with white background, Inter links at 14px weight 500 in #111111, a dark CTA button (#242424), sticky positioning"
- "Create a trust bar with grayscale company logos, horizontally centered, 16px gap between logos, on white background"
- "Design a feature section with 48px Cal Sans heading (weight 600, #242424), 16px Inter body text (weight 300, #898989, line-height 1.50), and a product screenshot with 12px radius and the card shadow"
### Iteration Guide
When refining existing screens generated with this design system:
1. Verify headings use Cal Sans at weight 600, body uses Inter — never mix them
2. Check that the palette is purely grayscale — if you see brand colors, remove them
3. Ensure card elevation uses the multi-layered shadow stack, not CSS borders
4. Confirm section spacing is generous (80px+) — if sections feel cramped, add more space
5. The overall tone should feel like a clean, professional scheduling tool — monochrome confidence without any decorative flourishes

# Design System Inspired by Canva
> Category: Design & Creative
> Visual creation platform. Vivid purple-blue gradient, generous spacing, friendly geometry.
## 1. Visual Theme & Atmosphere
Canva is the friendly face of design tools — the brand makes a point of looking inviting where Adobe looks intimidating. The page is built on a clean white canvas (`#ffffff`) with a signature **purple-to-blue gradient** (`#7d2ae8` → `#00c4cc`) used in the brand mark, hero buttons, and Pro/Magic moments. Surfaces are generously padded, edges are gently rounded (8–16px), and shadows are soft and cool-toned.
Typography uses **Canva Sans** (a custom geometric sans) for chrome and prose, with rounded letterforms that share DNA with brands like Airbnb and Asana. Weight contrast does the heavy lifting — 800 for hero display, 700 for section heads, 400 for body — while size hierarchy is more compressed than typical product brands so cards and templates read at a glance.
The shape system is ultra-soft: 12px on most cards, 16–20px on larger panels, 9999px on chips. Buttons are rectangles with a subtle elevation shadow (`0 2px 8px rgba(0,0,0,0.06)`) that grows on hover. Iconography is filled and rounded, never line-only — Canva's icons speak the same shape language as its UI.
**Key Characteristics:**
- White canvas with a violet-to-cyan gradient (`#7d2ae8` → `#00c4cc`)
- Canva Sans (rounded geometric) for everything; weight contrast over color
- 12–20px radii everywhere; 9999px pills for chips and tags
- Soft cool-toned shadows that grow on hover
- Filled rounded iconography — never outlined
- Vibrant secondary palette (coral, mint, tangerine) for category tags
- Pro/Magic moments lit by a static gradient — no animation
## 2. Color Palette & Roles
### Brand Gradient

- **Canva Cyan** (`#00c4cc`): Brand secondary; gradient terminus.
- **Canva Pink** (`#ff5757`): Tertiary brand accent (Magic Studio).
### Surface
- **Canvas** (`#ffffff`): Primary background.
- **Surface Subtle** (`#f4f5f7`): Section break, sidebar.
- **Surface Inset** (`#e8eaed`): Disabled, inset block.

- **Editorial (rare)**: `Canva Sans Display`, with fallback: `'Canva Sans', sans-serif`
- **Code (devtools only)**: `JetBrains Mono`, with fallback: `ui-monospace, Menlo, Consolas, monospace`
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Hero | Canva Sans | 64px (4rem) | 800 | 1.05 | -0.02em | Marketing hero, "Design anything." |
| H1 | Canva Sans | 36px (2.25rem) | 700 | 1.15 | -0.01em | Page heading |
| H2 | Canva Sans | 24px (1.5rem) | 700 | 1.2 | -0.005em | Section heading |
| H3 | Canva Sans | 18px (1.125rem) | 600 | 1.3 | normal | Sub-section, card title |
| Body Large | Canva Sans | 16px (1rem) | 400 | 1.55 | normal | Lede, marketing body |
| Body | Canva Sans | 14px (0.875rem) | 400 | 1.5 | normal | Standard UI prose |
| Caption | Canva Sans | 12px (0.75rem) | 500 | 1.4 | 0.005em | Metadata, hint text |
| Button | Canva Sans | 14px (0.875rem) | 600 | 1.2 | normal | Default button label |
| Tag | Canva Sans | 11px (0.6875rem) | 600 | 1.2 | 0.04em | Uppercase category chip |
### Principles
- **Weight contrast over color contrast**: hierarchy steps via 800→700→600→400; the surface stays neutral.
- **Tight line-height for cards**: card titles use 1.15–1.2 so a 3-line title still fits a 4:3 thumbnail.
- **No display serif**: Canva is sans-only across all surfaces; serifs appear only as user-selectable template fonts inside the editor.

# Design System Inspired by Claude (Anthropic)
> Category: AI & LLM
> Anthropic's AI assistant. Warm terracotta accent, clean editorial layout.
## 1. Visual Theme & Atmosphere
Claude's interface is a literary salon reimagined as a product page — warm, unhurried, and quietly intellectual. The entire experience is built on a parchment-toned canvas (`#f5f4ed`) that deliberately evokes the feeling of high-quality paper rather than a digital surface. Where most AI product pages lean into cold, futuristic aesthetics, Claude's design radiates human warmth, as if the AI itself has good taste in interior design.
The signature move is the custom Anthropic Serif typeface — a medium-weight serif with generous proportions that gives every headline the gravitas of a book title. Combined with organic, hand-drawn-feeling illustrations in terracotta (`#c96442`), black, and muted green, the visual language says "thoughtful companion" rather than "powerful tool." The serif headlines breathe at tight-but-comfortable line-heights (1.10–1.30), creating a cadence that feels more like reading an essay than scanning a product page.
What makes Claude's design truly distinctive is its warm neutral palette. Every gray has a yellow-brown undertone (`#5e5d59`, `#87867f`, `#4d4c48`) — there are no cool blue-grays anywhere. Borders are cream-tinted (`#f0eee6`, `#e8e6dc`), shadows use warm transparent blacks, and even the darkest surfaces (`#141413`, `#30302e`) carry a barely perceptible olive warmth. This chromatic consistency creates a space that feels lived-in and trustworthy.
**Key Characteristics:**
- Warm parchment canvas (`#f5f4ed`) evoking premium paper, not screens
- Custom Anthropic type family: Serif for headlines, Sans for UI, Mono for code
- Terracotta brand accent (`#c96442`) — warm, earthy, deliberately un-tech
- Exclusively warm-toned neutrals — every gray has a yellow-brown undertone
- Organic, editorial illustrations replacing typical tech iconography
- Ring-based shadow system (`0px 0px 0px 1px`) creating border-like depth without visible borders
- Magazine-like pacing with generous section spacing and serif-driven hierarchy
## 2. Color Palette & Roles
### Primary
- **Anthropic Near Black** (`#141413`): The primary text color and dark-theme surface — not pure black but a warm, almost olive-tinted dark that's gentler on the eyes. The warmest "black" in any major tech brand.
- **Terracotta Brand** (`#c96442`): The core brand color — a burnt orange-brown used for primary CTA buttons, brand moments, and the signature accent. Deliberately earthy and un-tech.
- **Coral Accent** (`#d97757`): A lighter, warmer variant of the brand color used for text accents, links on dark surfaces, and secondary emphasis.
### Secondary & Accent
- **Error Crimson** (`#b53333`): A deep, warm red for error states — serious without being alarming.
- **Focus Blue** (`#3898ec`): Standard blue for input focus rings — the only cool color in the entire system, used purely for accessibility.
### Surface & Background
- **Parchment** (`#f5f4ed`): The primary page background — a warm cream with a yellow-green tint that feels like aged paper. The emotional foundation of the entire design.
- **Ivory** (`#faf9f5`): The lightest surface — used for cards and elevated containers on the Parchment background. Barely distinguishable but creates subtle layering.
- **Pure White** (`#ffffff`): Reserved for specific button surfaces and maximum-contrast elements.
- **Warm Sand** (`#e8e6dc`): Button backgrounds and prominent interactive surfaces — a noticeably warm light gray.
- **Dark Surface** (`#30302e`): Dark-theme containers, nav borders, and elevated dark elements — warm charcoal.
- **Deep Dark** (`#141413`): Dark-theme page background and primary dark surface.
### Neutrals & Text
- **Charcoal Warm** (`#4d4c48`): Button text on light warm surfaces — the go-to dark-on-light text.
- **Olive Gray** (`#5e5d59`): Secondary body text — a distinctly warm medium-dark gray.
- **Stone Gray** (`#87867f`): Tertiary text, footnotes, and de-emphasized metadata.
- **Dark Warm** (`#3d3d3a`): Dark text links and emphasized secondary text.
- **Warm Silver** (`#b0aea5`): Text on dark surfaces — a warm, parchment-tinted light gray.
### Semantic & Accent
- **Border Cream** (`#f0eee6`): Standard light-theme border — barely visible warm cream, creating the gentlest possible containment.
- **Border Warm** (`#e8e6dc`): Prominent borders, section dividers, and emphasized containment on light surfaces.
- **Border Dark** (`#30302e`): Standard border on dark surfaces — maintains the warm tone.
- **Ring Warm** (`#d1cfc5`): Shadow ring color for button hover/focus states.
- **Ring Subtle** (`#dedc01`): Secondary ring variant for lighter interactive surfaces.
- **Ring Deep** (`#c2c0b6`): Deeper ring for active/pressed states.
### Gradient System
- Claude's design is **gradient-free** in the traditional sense. Depth and visual richness come from the interplay of warm surface tones, organic illustrations, and light/dark section alternation. The warm palette itself creates a "gradient" effect as the eye moves through cream → sand → stone → charcoal → black sections.
## 3. Typography Rules
### Font Family
- **Headline**: `Anthropic Serif`, with fallback: `Georgia`
- **Body / UI**: `Anthropic Sans`, with fallback: `Arial`
- **Code**: `Anthropic Mono`, with fallback: `Arial`
*Note: These are custom typefaces. For external implementations, Georgia serves as the serif substitute and system-ui/Inter as the sans substitute.*
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |

### Principles
- **Serif for authority, sans for utility**: Anthropic Serif carries all headline content with medium weight (500), giving every heading the gravitas of a published title. Anthropic Sans handles all functional UI text — buttons, labels, navigation — with quiet efficiency.
- **Single weight for serifs**: All Anthropic Serif headings use weight 500 — no bold, no light. This creates a consistent "voice" across all headline sizes, as if the same author wrote every heading.
- **Relaxed body line-height**: Most body text uses 1.60 line-height — significantly more generous than typical tech sites (1.4–1.5). This creates a reading experience closer to a book than a dashboard.
- **Tight-but-not-compressed headings**: Line-heights of 1.10–1.30 for headings are tight but never claustrophobic. The serif letterforms need breathing room that sans-serif fonts don't.
- **Micro letter-spacing on labels**: Small sans text (12px and below) uses deliberate letter-spacing (0.12px–0.5px) to maintain readability at tiny sizes.

- Creates a reading rhythm like chapters in a book
- Each section feels like a distinct environment
## 5. Layout Principles
### Spacing System
- Base unit: 8px
- Scale: 3px, 4px, 6px, 8px, 10px, 12px, 16px, 20px, 24px, 30px
- Button padding: asymmetric (0px 12px 0px 8px) or balanced (8px 16px)
- Card internal padding: approximately 24–32px
- Section vertical spacing: generous (estimated 80–120px between major sections)
### Grid & Container
- Max container width: approximately 1200px, centered
- Hero: centered with editorial layout
- Feature sections: single-column or 2–3 column card grids
- Model comparison: clean 3-column grid
- Full-width dark sections breaking the container for emphasis
### Whitespace Philosophy
- **Editorial pacing**: Each section breathes like a magazine spread — generous top/bottom margins create natural reading pauses.
- **Serif-driven rhythm**: The serif headings establish a literary cadence that demands more whitespace than sans-serif designs.
- **Content island approach**: Sections alternate between light and dark environments, creating distinct "rooms" for each message.
### Border Radius Scale
- Sharp (4px): Minimal inline elements
- Subtly rounded (6–7.5px): Small buttons, secondary interactive elements
- Comfortably rounded (8–8.5px): Standard buttons, cards, containers
- Generously rounded (12px): Primary buttons, input fields, nav elements
- Very rounded (16px): Featured containers, video players, tab lists
- Highly rounded (24px): Tag-like elements, highlighted containers
- Maximum rounded (32px): Hero containers, embedded media, large cards
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow, no border | Parchment background, inline text |
| Contained (Level 1) | `1px solid #f0eee6` (light) or `1px solid #30302e` (dark) | Standard cards, sections |
| Ring (Level 2) | `0px 0px 0px 1px` ring shadows using warm grays | Interactive cards, buttons, hover states |
| Whisper (Level 3) | `rgba(0,0,0,0.05) 0px 4px 24px` | Elevated feature cards, product screenshots |
| Inset (Level 4) | `inset 0px 0px 0px 1px` at 15% opacity | Active/pressed button states |
**Shadow Philosophy**: Claude communicates depth through **warm-toned ring shadows** rather than traditional drop shadows. The signature `0px 0px 0px 1px` pattern creates a border-like halo that's softer than an actual border — it's a shadow pretending to be a border, or a border that's technically a shadow. When drop shadows do appear, they're extremely soft (0.05 opacity, 24px blur) — barely visible lifts that suggest floating rather than casting.
### Decorative Depth
- **Light/Dark alternation**: The most dramatic depth effect comes from alternating between Parchment (`#f5f4ed`) and Near Black (`#141413`) sections — entire sections shift elevation by changing the ambient light level.
- **Warm ring halos**: Button and card interactions use ring shadows that match the warm palette — never cool-toned or generic gray.
## 7. Do's and Don'ts
### Do
- Use Parchment (`#f5f4ed`) as the primary light background — the warm cream tone IS the Claude personality
- Use Anthropic Serif at weight 500 for all headlines — the single-weight consistency is intentional
- Use Terracotta Brand (`#c96442`) only for primary CTAs and the highest-signal brand moments
- Keep all neutrals warm-toned — every gray should have a yellow-brown undertone
- Use ring shadows (`0px 0px 0px 1px`) for interactive element states instead of drop shadows
- Maintain the editorial serif/sans hierarchy — serif for content headlines, sans for UI
- Use generous body line-height (1.60) for a literary reading experience
- Alternate between light and dark sections to create chapter-like page rhythm
- Apply generous border-radius (12–32px) for a soft, approachable feel
### Don't
- Don't use cool blue-grays anywhere — the palette is exclusively warm-toned
- Don't use bold (700+) weight on Anthropic Serif — weight 500 is the ceiling for serifs
- Don't introduce saturated colors beyond Terracotta — the palette is deliberately muted
- Don't use sharp corners (< 6px radius) on buttons or cards — softness is core to the identity
- Don't apply heavy drop shadows — depth comes from ring shadows and background color shifts
- Don't use pure white (`#ffffff`) as a page background — Parchment (`#f5f4ed`) or Ivory (`#faf9f5`) are always warmer
- Don't use geometric/tech-style illustrations — Claude's illustrations are organic and hand-drawn-feeling
- Don't reduce body line-height below 1.40 — the generous spacing supports the editorial personality
- Don't use monospace fonts for non-code content — Anthropic Mono is strictly for code
- Don't mix in sans-serif for headlines — the serif/sans split is the typographic identity
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Small Mobile | <479px | Minimum layout, stacked everything, compact typography |
| Mobile | 479–640px | Single column, hamburger nav, reduced heading sizes |
| Large Mobile | 640–767px | Slightly wider content area |
| Tablet | 768–991px | 2-column grids begin, condensed nav |
| Desktop | 992px+ | Full multi-column layout, expanded nav, maximum hero typography (64px) |
### Touch Targets
- Buttons use generous padding (8–16px vertical minimum)
- Navigation links adequately spaced for thumb navigation
- Card surfaces serve as large touch targets
- Minimum recommended: 44x44px
### Collapsing Strategy
- **Navigation**: Full horizontal nav collapses to hamburger on mobile
- **Feature sections**: Multi-column → stacked single column
- **Hero text**: 64px → 36px → ~25px progressive scaling
- **Model cards**: 3-column → stacked vertical
- **Section padding**: Reduces proportionally but maintains editorial rhythm
- **Illustrations**: Scale proportionally, maintain aspect ratios
### Image Behavior
- Product screenshots scale proportionally within rounded containers
- Illustrations maintain quality at all sizes
- Video embeds maintain 16:9 aspect ratio with rounded corners
- No art direction changes between breakpoints
## 9. Agent Prompt Guide
### Quick Color Reference
- Brand CTA: "Terracotta Brand (#c96442)"
- Page Background: "Parchment (#f5f4ed)"
- Card Surface: "Ivory (#faf9f5)"
- Primary Text: "Anthropic Near Black (#141413)"
- Secondary Text: "Olive Gray (#5e5d59)"
- Tertiary Text: "Stone Gray (#87867f)"
- Borders (light): "Border Cream (#f0eee6)"
- Dark Surface: "Dark Surface (#30302e)"
### Example Component Prompts
- "Create a hero section on Parchment (#f5f4ed) with a headline at 64px Anthropic Serif weight 500, line-height 1.10. Use Anthropic Near Black (#141413) text. Add a subtitle in Olive Gray (#5e5d59) at 20px Anthropic Sans with 1.60 line-height. Place a Terracotta Brand (#c96442) CTA button with Ivory text, 12px radius."
- "Design a feature card on Ivory (#faf9f5) with a 1px solid Border Cream (#f0eee6) border and comfortably rounded corners (8px). Title in Anthropic Serif at 25px weight 500, description in Olive Gray (#5e5d59) at 16px Anthropic Sans. Add a whisper shadow (rgba(0,0,0,0.05) 0px 4px 24px)."
- "Build a dark section on Anthropic Near Black (#141413) with Ivory (#faf9f5) headline text in Anthropic Serif at 52px weight 500. Use Warm Silver (#b0aea5) for body text. Borders in Dark Surface (#30302e)."
- "Create a button in Warm Sand (#e8e6dc) with Charcoal Warm (#4d4c48) text, 8px radius, and a ring shadow (0px 0px 0px 1px #d1cfc5). Padding: 0px 12px 0px 8px."
- "Design a model comparison grid with three cards on Ivory surfaces. Each card gets a Border Warm (#e8e6dc) top border, model name in Anthropic Serif at 25px, and description in Olive Gray at 15px Anthropic Sans."
### Iteration Guide
1. Focus on ONE component at a time
2. Reference specific color names — "use Olive Gray (#5e5d59)" not "make it gray"
3. Always specify warm-toned variants — no cool grays
4. Describe serif vs sans usage explicitly — "Anthropic Serif for the heading, Anthropic Sans for the label"
5. For shadows, use "ring shadow (0px 0px 0px 1px)" or "whisper shadow" — never generic "drop shadow"
6. Specify the warm background — "on Parchment (#f5f4ed)" or "on Near Black (#141413)"
7. Keep illustrations organic and conceptual — describe "hand-drawn-feeling" style

# Design System Inspired by Clay
> Category: Design & Creative
> Creative agency. Organic shapes, soft gradients, art-directed layout.
## 1. Visual Theme & Atmosphere
Clay's website is a warm, playful celebration of color that treats B2B data enrichment like a craft rather than an enterprise chore. The design language is built on a foundation of warm cream backgrounds (`#faf9f7`) and oat-toned borders (`#dad4c8`, `#eee9df`) that give every surface the tactile quality of handmade paper. Against this artisanal canvas, a vivid swatch palette explodes with personality — Matcha green, Slushie cyan, Lemon gold, Ube purple, Pomegranate pink, Blueberry navy, and Dragonfruit magenta — each named like flavors at a juice bar, not colors in an enterprise UI kit.
The typography is anchored by Roobert, a geometric sans-serif with character, loaded with an extensive set of OpenType stylistic sets (`"ss01"`, `"ss03"`, `"ss10"`, `"ss11"`, `"ss12"`) that give the text a distinctive, slightly quirky personality. At display scale (80px, weight 600), Roobert uses aggressive negative letter-spacing (-3.2px) that compresses headlines into punchy, billboard-like statements. Space Mono serves as the monospace companion for code and technical labels, completing the craft-meets-tech duality.
What makes Clay truly distinctive is its hover micro-animations: buttons on hover rotate slightly (`rotateZ(-8deg)`), translate upward (`translateY(-80%)`), change background to a contrasting swatch color, and cast a hard offset shadow (`rgb(0,0,0) -7px 7px`). This playful hover behavior — where a button literally tilts and jumps on interaction — creates a sense of physical delight that's rare in B2B software. Combined with generously rounded containers (24px–40px radius), dashed borders alongside solid ones, and a multi-layer shadow system that includes inset highlights, Clay feels like a design system that was made by people who genuinely enjoy making things.
**Key Characteristics:**
- Warm cream canvas (`#faf9f7`) with oat-toned borders (`#dad4c8`) — artisanal, not clinical
- Named swatch palette: Matcha, Slushie, Lemon, Ube, Pomegranate, Blueberry, Dragonfruit
- Roobert font with 5 OpenType stylistic sets — quirky geometric character
- Playful hover animations: rotateZ(-8deg) + translateY(-80%) + hard offset shadow
- Space Mono for code and technical labels
- Generous border radius: 24px cards, 40px sections, 1584px pills
- Mixed border styles: solid + dashed in the same interface
- Multi-layer shadow with inset highlight: `0px 1px 1px` + `-1px inset` + `-0.5px`

## 3. Typography Rules
### Font Families
- **Primary**: `Roobert`, fallback: `Arial`
- **Monospace**: `Space Mono`
- **OpenType Features**: `"ss01"`, `"ss03"`, `"ss10"`, `"ss11"`, `"ss12"` on all Roobert text (display uses all 5; body/UI uses `"ss03"`, `"ss10"`, `"ss11"`, `"ss12"`)
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display Hero | Roobert | 80px (5.00rem) | 600 | 1.00 (tight) | -3.2px | All 5 stylistic sets |
| Display Secondary | Roobert | 60px (3.75rem) | 600 | 1.00 (tight) | -2.4px | All 5 stylistic sets |
| Section Heading | Roobert | 44px (2.75rem) | 600 | 1.10 (tight) | -0.88px to -1.32px | All 5 stylistic sets |
| Card Heading | Roobert | 32px (2.00rem) | 600 | 1.10 (tight) | -0.64px | All 5 stylistic sets |
| Feature Title | Roobert | 20px (1.25rem) | 600 | 1.40 | -0.4px | All 5 stylistic sets |
| Sub-heading | Roobert | 20px (1.25rem) | 500 | 1.50 | -0.16px | 4 stylistic sets (no ss01) |
| Body Large | Roobert | 20px (1.25rem) | 400 | 1.40 | normal | 4 stylistic sets |
| Body | Roobert | 18px (1.13rem) | 400 | 1.60 (relaxed) | -0.36px | 4 stylistic sets |
| Body Standard | Roobert | 16px (1.00rem) | 400 | 1.50 | normal | 4 stylistic sets |
| Body Medium | Roobert | 16px (1.00rem) | 500 | 1.20–1.40 | -0.16px to -0.32px | 4–5 stylistic sets |
| Button | Roobert | 16px (1.00rem) | 500 | 1.50 | -0.16px | 4 stylistic sets |
| Button Large | Roobert | 24px (1.50rem) | 400 | 1.50 | normal | 4 stylistic sets |
| Button Small | Roobert | 12.8px (0.80rem) | 500 | 1.50 | -0.128px | 4 stylistic sets |
| Nav Link | Roobert | 15px (0.94rem) | 500 | 1.60 (relaxed) | normal | 4 stylistic sets |
| Caption | Roobert | 14px (0.88rem) | 400 | 1.50–1.60 | -0.14px | 4 stylistic sets |
| Small | Roobert | 12px (0.75rem) | 400 | 1.50 | normal | 4 stylistic sets |
| Uppercase Label | Roobert | 12px (0.75rem) | 600 | 1.20 (tight) | 1.08px | `text-transform: uppercase`, 4 sets |
| Badge | Roobert | 9.6px | 600 | — | — | Pill badges |
### Principles
- **Five stylistic sets as identity**: The combination of `"ss01"`, `"ss03"`, `"ss10"`, `"ss11"`, `"ss12"` on Roobert creates a distinctive typographic personality. `ss01` is reserved for headings and emphasis — body text omits it, creating a subtle hierarchy through glyph variation.
- **Aggressive display compression**: -3.2px at 80px, -2.4px at 60px — the most compressed display tracking alongside the most generous body spacing (1.60 line-height), creating dramatic contrast.
- **Weight 600 for headings, 500 for UI, 400 for body**: Clean three-tier system where each weight has a strict role.
- **Uppercase labels with positive tracking**: 12px uppercase at 1.08px letter-spacing creates the systematic wayfinding pattern.

- Focus: `rgb(20, 110, 245) solid 2px` outline
### Navigation
- Sticky top nav on cream background
- Roobert 15px weight 500 for nav links
- Clay logo left-aligned
- CTA buttons right-aligned with pill radius
- Border bottom: `1px solid #dad4c8`
- Mobile: hamburger collapse at 767px
### Image Treatment
- Product screenshots in white cards with oat borders
- Colorful illustrated sections with swatch background colors
- 8px–24px radius on images
- Full-width colorful section backgrounds
### Distinctive Components
**Swatch Color Sections**
- Full-width sections with swatch-colored backgrounds (matcha green, slushie cyan, ube purple, lemon gold)
- White text on dark swatches, black text on light swatches
- Each section tells a distinct product story through its color
**Playful Hover Buttons**
- Rotate -8deg + translate upward on hover
- Hard offset shadow (`-7px 7px`) instead of soft blur
- Background transitions to contrasting swatch color
- Creates a physical, toy-like interaction quality
**Dashed Border Elements**
- Dashed borders (`1px dashed #dad4c8`) alongside solid borders
- Used for secondary containers and decorative elements
- Adds a hand-drawn, craft-like quality
## 5. Layout Principles
### Spacing System
- Base unit: 8px
- Scale: 1px, 2px, 4px, 6.4px, 8px, 12px, 12.8px, 16px, 18px, 20px, 24px
### Grid & Container
- Max content width centered
- Feature sections alternate between white cards and colorful swatch backgrounds
- Card grids: 2–3 columns on desktop
- Full-width colorful sections break the grid
- Footer with generous 40px radius container
### Whitespace Philosophy
- **Warm, generous breathing**: The cream background provides a warm rest between content blocks. Spacing is generous but not austere — it feels inviting, like a well-set table.
- **Color as spatial rhythm**: The alternating swatch-colored sections create visual rhythm through hue rather than just whitespace. Each color section is its own "room."
- **Craft-like density inside cards**: Within cards, content is compact and well-organized, contrasting with the generous outer spacing.
### Border Radius Scale
- Sharp (4px): Ghost buttons, inputs
- Standard (8px): Small cards, images, links
- Badge (11px): Tag badges
- Card (12px): Standard cards, buttons
- Feature (24px): Feature cards, images, panels
- Section (40px): Large sections, footer, containers
- Pill (1584px): CTAs, pill-shaped buttons
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow, cream canvas | Page background |
| Clay Shadow (Level 1) | `rgba(0,0,0,0.1) 0px 1px 1px, rgba(0,0,0,0.04) 0px -1px inset, rgba(0,0,0,0.05) 0px -0.5px` | Cards, buttons — multi-layer with inset highlight |
| Hover Hard (Level 2) | `rgb(0,0,0) -7px 7px` | Hover state — playful hard offset shadow |
| Focus (Level 3) | `rgb(20, 110, 245) solid 2px` | Keyboard focus ring |
**Shadow Philosophy**: Clay's shadow system is uniquely three-layered: a downward cast (`0px 1px 1px`), an upward inset highlight (`0px -1px 1px inset`), and a subtle edge (`0px -0.5px 1px`). This creates a "pressed into clay" quality where elements feel both raised AND embedded — like a clay tablet where content is stamped into the surface. The hover hard shadow (`-7px 7px`) is deliberately retro-graphic, referencing print-era drop shadows and adding physical playfulness.
### Decorative Depth
- Full-width swatch-colored sections create dramatic depth through color contrast
- Dashed borders add visual texture alongside solid borders
- Product illustrations with warm, organic art style
## 7. Do's and Don'ts
### Do
- Use warm cream (`#faf9f7`) as the page background — the warmth is the identity
- Apply all 5 OpenType stylistic sets on Roobert headings: `"ss01", "ss03", "ss10", "ss11", "ss12"`
- Use the named swatch palette (Matcha, Slushie, Lemon, Ube, Pomegranate, Blueberry) for section backgrounds
- Apply the playful hover animation: `rotateZ(-8deg)`, `translateY(-80%)`, hard shadow `-7px 7px`
- Use warm oat borders (`#dad4c8`) — not neutral gray
- Mix solid and dashed borders for visual variety
- Use generous radius: 24px for cards, 40px for sections
- Use weight 600 exclusively for headings, 500 for UI, 400 for body
### Don't
- Don't use cool gray backgrounds — the warm cream (`#faf9f7`) is non-negotiable
- Don't use neutral gray borders (`#ccc`, `#ddd`) — always use the warm oat tones
- Don't mix more than 2 swatch colors in the same section
- Don't skip the OpenType stylistic sets — they define Roobert's character
- Don't use subtle hover effects — the rotation + hard shadow is the signature interaction
- Don't use small border radius (<12px) on feature cards — the generous rounding is structural
- Don't use standard shadows (blur-based) — Clay uses hard offset and multi-layer inset
- Don't forget the uppercase labels with 1.08px tracking — they're the wayfinding system
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile Small | <479px | Single column, tight padding |
| Mobile | 479–767px | Standard mobile, stacked layout |
| Tablet | 768–991px | 2-column grids, condensed nav |
| Desktop | 992px+ | Full layout, 3-column grids, expanded sections |
### Touch Targets
- Buttons: minimum 6.4px + 12.8px padding for adequate touch area
- Nav links: 15px font with generous spacing
- Mobile: full-width buttons for easy tapping
### Collapsing Strategy
- Hero: 80px → 60px → smaller display text
- Navigation: horizontal → hamburger at 767px
- Feature sections: multi-column → stacked
- Colorful sections: maintain full-width but compress padding
- Card grids: 3-column → 2-column → single column
### Image Behavior
- Product screenshots scale proportionally
- Colorful section illustrations adapt to viewport width
- Rounded corners maintained across breakpoints
## 9. Agent Prompt Guide
### Quick Color Reference
- Background: Warm Cream (`#faf9f7`)
- Text: Clay Black (`#000000`)
- Secondary text: Warm Silver (`#9f9b93`)
- Border: Oat Border (`#dad4c8`)
- Green accent: Matcha 600 (`#078a52`)
- Cyan accent: Slushie 500 (`#3bd3fd`)
- Gold accent: Lemon 500 (`#fbbd41`)
- Purple accent: Ube 800 (`#43089f`)
- Pink accent: Pomegranate 400 (`#fc7981`)
### Example Component Prompts
- "Create a hero on warm cream (#faf9f7) background. Headline at 80px Roobert weight 600, line-height 1.00, letter-spacing -3.2px, OpenType 'ss01 ss03 ss10 ss11 ss12', black text. Subtitle at 20px weight 400, line-height 1.40, #9f9b93 text. Two buttons: white solid pill (12px radius) and ghost outlined (4px radius, 1px solid #717989)."
- "Design a colorful section with Matcha 800 (#02492a) background. Heading at 44px Roobert weight 600, letter-spacing -1.32px, white text. Body at 18px weight 400, line-height 1.60, #84e7a5 text. White card inset with oat border (#dad4c8), 24px radius."
- "Build a button with playful hover: default transparent background, black text, 16px Roobert weight 500. On hover: background #434346, text white, transform rotateZ(-8deg) translateY(-80%), hard shadow rgb(0,0,0) -7px 7px."
- "Create a card: white background, 1px solid #dad4c8 border, 24px radius. Shadow: rgba(0,0,0,0.1) 0px 1px 1px, rgba(0,0,0,0.04) 0px -1px 1px inset. Title at 32px Roobert weight 600, letter-spacing -0.64px."
- "Design an uppercase label: 12px Roobert weight 600, text-transform uppercase, letter-spacing 1.08px, OpenType 'ss03 ss10 ss11 ss12'."
### Iteration Guide
1. Start with warm cream (#faf9f7) — never cool white
2. Swatch colors are for full sections, not small accents — go bold with matcha, slushie, ube
3. Oat borders (#dad4c8) everywhere — dashed variants for decoration
4. OpenType stylistic sets are mandatory — they make Roobert look like Roobert
5. Hover animations are the signature — rotation + hard shadow, not subtle fades
6. Generous radius: 24px cards, 40px sections — nothing looks sharp or corporate
7. Three weights: 600 (headings), 500 (UI), 400 (body) — strict roles

# Design System Inspired by ClickHouse
> Category: Backend & Data
> Fast analytics database. Yellow-accented, technical documentation style.
## 1. Visual Theme & Atmosphere
ClickHouse's interface is a high-performance cockpit rendered in acid yellow-green on obsidian black — a design that screams "speed" before you read a single word. The entire experience lives in darkness: pure black backgrounds (`#000000`) with dark charcoal cards (`#414141` borders) creating a terminal-grade aesthetic where the only chromatic interruption is the signature neon yellow-green (`#faff69`) that slashes across CTAs, borders, and highlighted moments like a highlighter pen on a dark console.
The typography is aggressively heavy — Inter at weight 900 (Black) for the hero headline at 96px creates text blocks that feel like they have physical mass. This "database for AI" site communicates raw power through visual weight: thick type, high-contrast neon accents, and performance stats displayed as oversized numbers. There's nothing subtle about ClickHouse's design, and that's entirely the point — it mirrors the product's promise of extreme speed and performance.
What makes ClickHouse distinctive is the electrifying tension between the near-black canvas and the neon yellow-green accent. This color combination (`#faff69` on `#000000`) creates one of the highest-contrast pairings in any tech brand, making every CTA button, every highlighted card, and every accent border impossible to miss. Supporting this is a forest green (`#166534`) for secondary CTAs that adds depth to the action hierarchy without competing with the neon.
**Key Characteristics:**
- Pure black canvas (#000000) with neon yellow-green (#faff69) accent — maximum contrast
- Extra-heavy display typography: Inter at weight 900 (Black) up to 96px
- Dark charcoal card system with #414141 borders at 80% opacity
- Forest green (#166534) secondary CTA buttons
- Performance stats as oversized display numbers
- Uppercase labels with wide letter-spacing (1.4px) for navigation structure
- Active/pressed state shifts text to pale yellow (#f4f692)
- All links hover to neon yellow-green — unified interactive signal
- Inset shadows on select elements creating "pressed into the surface" depth
## 2. Color Palette & Roles
### Primary
- **Neon Volt** (`#faff69`): The signature brand color — a vivid acid yellow-green that's the sole chromatic accent on the black canvas. Used for primary CTAs, accent borders, link hovers, and highlighted moments.
- **Forest Green** (`#166534`): Secondary CTA color — a deep, saturated green for "Get Started" and primary action buttons that need distinction from the neon.
- **Dark Forest** (`#14572f`): A darker green variant for borders and secondary accents.
### Secondary & Accent
- **Pale Yellow** (`#f4f692`): Active/pressed state text color — a softer, more muted version of Neon Volt for state feedback.
- **Border Olive** (`#4f5100`): A dark olive-yellow for ghost button borders — the neon's muted sibling.
- **Olive Dark** (`#161600`): The darkest neon-tinted color for subtle brand text.
### Surface & Background
- **Pure Black** (`#000000`): The primary page background — absolute black for maximum contrast.
- **Near Black** (`#141414`): Button backgrounds and slightly elevated dark surfaces.
- **Charcoal** (`#414141`): The primary border color at 80% opacity — the workhorse for card and container containment.
- **Deep Charcoal** (`#343434`): Darker border variant for subtle division lines.
- **Hover Gray** (`#3a3a3a`): Button hover state background — slightly lighter than Near Black.
### Neutrals & Text
- **Pure White** (`#ffffff`): Primary text on dark surfaces.
- **Silver** (`#a0a0a0`): Secondary body text and muted content.
- **Mid Gray** (`#585858` at 28%): Subtle gray overlay for depth effects.
- **Border Gray** (`#e5e7eb`): Light border variant (used in rare light contexts).
### Gradient System
- **None in the traditional sense.** ClickHouse uses flat color blocks and high-contrast borders. The "gradient" is the contrast itself — neon yellow-green against pure black creates a visual intensity that gradients would dilute.
## 3. Typography Rules
### Font Family
- **Primary**: `Inter` (Next.js optimized variant `__Inter_d1b8ee`)
- **Secondary Display**: `Basier` (`__basier_a58b65`), with fallbacks: `Arial, Helvetica`
- **Code**: `Inconsolata` (`__Inconsolata_a25f62`)
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display Mega | Inter | 96px (6rem) | 900 | 1.00 (tight) | normal | Maximum impact, extra-heavy |
| Display / Hero | Inter | 72px (4.5rem) | 700 | 1.00 (tight) | normal | Section hero titles |
| Feature Heading | Basier | 36px (2.25rem) | 600 | 1.30 (tight) | normal | Feature section anchors |
| Sub-heading | Inter / Basier | 24px (1.5rem) | 600–700 | 1.17–1.38 | normal | Card headings |
| Feature Title | Inter / Basier | 20px (1.25rem) | 600–700 | 1.40 | normal | Small feature titles |
| Body Large | Inter | 18px (1.13rem) | 400–700 | 1.56 | normal | Intro paragraphs, button text |
| Body / Button | Inter | 16px (1rem) | 400–700 | 1.50 | normal | Standard body, nav, buttons |
| Caption | Inter | 14px (0.88rem) | 400–700 | 1.43 | normal | Metadata, descriptions, links |
| Uppercase Label | Inter | 14px (0.88rem) | 600 | 1.43 | 1.4px | Section overlines, wide-tracked |
| Code | Inconsolata | 16px (1rem) | 600 | 1.50 | normal | Code blocks, commands |
| Small | Inter | 12px (0.75rem) | 500 | 1.33 | normal | Smallest text |
| Micro | Inter | 11.2px (0.7rem) | 500 | 1.79 (relaxed) | normal | Tags, tiny labels |
### Principles
- **Weight 900 is the weapon**: The display headline uses Inter Black (900) — a weight most sites never touch. Combined with 96px size, this creates text with a physical, almost architectural presence.
- **Full weight spectrum**: The system uses 400, 500, 600, 700, and 900 — covering the full gamut. Weight IS hierarchy.
- **Uppercase with maximum tracking**: Section overlines use 1.4px letter-spacing — wider than most systems — creating bold structural labels that stand out against the dense dark background.
- **Dual sans-serif**: Inter handles display and body; Basier handles feature section headings at 600 weight. This creates a subtle personality shift between "data/performance" (Inter) and "product/feature" (Basier) contexts.
## 4. Component Stylings
### Buttons
**Neon Primary**
- Background: Neon Volt (`#faff69`)
- Text: Near Black (`#151515`)

- Radius: 4px (small elements) or 8px (cards, containers)
- Shadow Level 1: subtle (`rgba(0,0,0,0.1) 0px 1px 3px, rgba(0,0,0,0.1) 0px 1px 2px -1px`)
- Shadow Level 2: medium (`rgba(0,0,0,0.1) 0px 10px 15px -3px, rgba(0,0,0,0.1) 0px 4px 6px -4px`)
- Shadow Level 3: inset (`rgba(0,0,0,0.06) 0px 4px 4px, rgba(0,0,0,0.14) 0px 4px 25px inset`) — the "pressed" effect
- Neon-highlighted cards: selected/active cards get neon yellow-green border or accent
### Navigation
- Dark nav on black background
- Logo: ClickHouse wordmark + icon in yellow/neon
- Links: white text, hover to Neon Volt (#faff69)
- CTA: Neon Volt button or Forest Green button
- Uppercase labels for categories
### Distinctive Components
**Performance Stats**
- Oversized numbers (72px+, weight 700–900)
- Brief descriptions beneath
- High-contrast neon accents on key metrics
- The primary visual proof of performance claims
**Neon-Highlighted Card**
- Standard dark card with neon yellow-green border highlight
- Creates "selected" or "featured" treatment
- The accent border makes the card pop against the dark canvas
**Code Blocks**
- Dark surface with Inconsolata at weight 600
- Neon and white syntax highlighting
- Terminal-like aesthetic
**Trust Bar**
- Company logos on dark background
- Monochrome/white logo treatment
- Horizontal layout
## 5. Layout Principles
### Spacing System
- Base unit: 8px
- Scale: 2px, 6px, 7px, 8px, 10px, 12px, 16px, 20px, 24px, 25px, 32px, 40px, 44px, 48px, 64px
- Button padding: 12px 16px (standard), 0px 16px (compact), 0px 32px (wide ghost)
- Section vertical spacing: generous (48–64px)
### Grid & Container
- Max container width: up to 2200px (extra-wide) with responsive scaling
- Hero: full-width dark with massive typography
- Feature sections: multi-column card grids with dark borders
- Stats: horizontal metric bar
- Full-dark page — no light sections
### Whitespace Philosophy
- **Dark void as canvas**: The pure black background provides infinite depth — elements float in darkness.
- **Dense information**: Feature cards and stats are packed with data, reflecting the database product's performance focus.
- **Neon highlights as wayfinding**: Yellow-green accents guide the eye through the dark interface like runway lights.
### Border Radius Scale
- Sharp (4px): Buttons, badges, small elements, code blocks
- Comfortable (8px): Cards, containers, dividers
- Pill (9999px): Toggle buttons, status indicators
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Black background, text blocks |
| Bordered (Level 1) | `1px solid rgba(65,65,65,0.8)` | Standard cards, containers |
| Subtle (Level 2) | `0px 1px 3px rgba(0,0,0,0.1)` | Subtle card lift |
| Elevated (Level 3) | `0px 10px 15px -3px rgba(0,0,0,0.1)` | Feature cards, hover states |
| Pressed/Inset (Level 4) | `0px 4px 25px rgba(0,0,0,0.14) inset` | Active/pressed elements — "sunk into the surface" |
| Neon Highlight (Level 5) | Neon Volt border (`#faff69`) | Featured/selected cards, maximum emphasis |
**Shadow Philosophy**: ClickHouse uses shadows on a black canvas, where they're barely visible — they exist more for subtle dimensionality than obvious elevation. The most distinctive depth mechanism is the **inset shadow** (Level 4), which creates a "pressed into the surface" effect unique to ClickHouse. The neon border highlight (Level 5) is the primary attention-getting depth mechanism.
## 7. Do's and Don'ts
### Do
- Use Neon Volt (#faff69) as the sole chromatic accent — it must pop against pure black
- Use Inter at weight 900 for hero display text — the extreme weight IS the personality
- Keep everything on pure black (#000000) — never use dark gray as the page background
- Use charcoal borders (rgba(65,65,65,0.8)) for all card containment
- Apply Forest Green (#166534) for primary CTA buttons — distinct from neon for action hierarchy
- Show performance stats as oversized display numbers — it's the core visual argument
- Use uppercase with wide letter-spacing (1.4px) for section labels
- Apply Pale Yellow (#f4f692) for active/pressed text states
- Link hovers should ALWAYS shift to Neon Volt — unified interactive feedback
### Don't
- Don't introduce additional colors — the palette is strictly black, neon, green, and gray
- Don't use the neon as a background fill — it's an accent and border color only (except on CTA buttons)
- Don't reduce display weight below 700 — heavy weight is core to the personality
- Don't use light/white backgrounds anywhere — the entire experience is dark
- Don't round corners beyond 8px — the sharp geometry reflects database precision
- Don't use soft/diffused shadows on black — they're invisible. Use border-based depth instead
- Don't skip the inset shadow on active states — the "pressed" effect is distinctive
- Don't use warm neutrals — all grays are perfectly neutral
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | <640px | Single column, stacked cards |
| Small Tablet | 640–768px | Minor adjustments |
| Tablet | 768–1024px | 2-column grids |
| Desktop | 1024–1280px | Standard layout |
| Large Desktop | 1280–1536px | Expanded content |
| Ultra-wide | 1536–2200px | Maximum container width |
### Touch Targets
- Buttons with 12px 16px padding minimum
- Card surfaces as touch targets
- Adequate nav link spacing
### Collapsing Strategy
- **Hero text**: 96px → 72px → 48px → 36px
- **Feature grids**: Multi-column → 2 → 1 column
- **Stats**: Horizontal → stacked
- **Navigation**: Full → hamburger
### Image Behavior
- Product screenshots maintain aspect ratio
- Code blocks use horizontal scroll on narrow screens
- All images on dark backgrounds
## 9. Agent Prompt Guide
### Quick Color Reference
- Brand Accent: "Neon Volt (#faff69)"
- Page Background: "Pure Black (#000000)"
- CTA Green: "Forest Green (#166534)"
- Card Border: "Charcoal (rgba(65,65,65,0.8))"
- Primary Text: "Pure White (#ffffff)"
- Secondary Text: "Silver (#a0a0a0)"
- Active State: "Pale Yellow (#f4f692)"
- Button Surface: "Near Black (#141414)"
### Example Component Prompts
- "Create a hero section on Pure Black (#000000) with a massive headline at 96px Inter weight 900, line-height 1.0. Pure White text. Add a Neon Volt (#faff69) CTA button (dark text, 4px radius, 0px 16px padding) and a ghost button (transparent, 1px solid #4f5100 border)."
- "Design a feature card on black with 1px solid rgba(65,65,65,0.8) border and 8px radius. Title at 24px Inter weight 700, body at 16px in Silver (#a0a0a0). Add a neon-highlighted variant with 1px solid #faff69 border."
- "Build a performance stats bar: large numbers at 72px Inter weight 700 in Pure White. Brief descriptions at 14px in Silver. On black background."
- "Create a Forest Green (#166534) CTA button: white text, 12px 16px padding, 4px radius, 1px solid #141414 border. Hover: bg shifts to #3a3a3a, text to 80% opacity."
- "Design an uppercase section label: 14px Inter weight 600, letter-spacing 1.4px, uppercase. Silver (#a0a0a0) text on black background."
### Iteration Guide
1. Keep everything on pure black — no dark gray alternatives
2. Neon Volt (#faff69) is for accents and CTAs only — never large backgrounds
3. Weight 900 for hero, 700 for headings, 600 for labels, 400-500 for body
4. Active states use Pale Yellow (#f4f692) — not just opacity changes
5. All links hover to Neon Volt — consistent interactive feedback
6. Charcoal borders (rgba(65,65,65,0.8)) are the primary depth mechanism

# Design System Inspired by Cohere
> Category: AI & LLM
> Enterprise AI platform. Vibrant gradients, data-rich dashboard aesthetic.
## 1. Visual Theme & Atmosphere
Cohere's interface is a polished enterprise command deck — confident, clean, and designed to make AI feel like serious infrastructure rather than a consumer toy. The experience lives on a bright white canvas where content is organized into generously rounded cards (22px radius) that create an organic, cloud-like containment language. This is a site that speaks to CTOs and enterprise architects: professional without being cold, sophisticated without being intimidating.
The design language bridges two worlds with a dual-typeface system: CohereText, a custom display serif with tight tracking, gives headlines the gravitas of a technology manifesto, while Unica77 Cohere Web handles all body and UI text with geometric Swiss precision. This serif/sans pairing creates a "confident authority meets engineering clarity" personality that perfectly reflects an enterprise AI platform.
Color is used with extreme restraint — the interface is almost entirely black-and-white with cool gray borders (`#d9d9dd`, `#e5e7eb`). Purple-violet appears only in photographic hero bands, gradient sections, and the interactive blue (`#1863dc`) that signals hover and focus states. This chromatic restraint means that when color DOES appear — in product screenshots, enterprise photography, and the deep purple section — it carries maximum visual weight.
**Key Characteristics:**
- Bright white canvas with cool gray containment borders
- 22px signature border-radius — the distinctive "Cohere card" roundness
- Dual custom typeface: CohereText (display serif) + Unica77 (body sans)
- Enterprise-grade chromatic restraint: black, white, cool grays, minimal purple-blue accent
- Deep purple/violet hero sections providing dramatic contrast
- Ghost/transparent buttons that shift to blue on hover
- Enterprise photography showing diverse real-world applications
- CohereMono for code and technical labels with uppercase transforms
## 2. Color Palette & Roles
### Primary
- **Cohere Black** (`#000000`): Primary headline text and maximum-emphasis elements.
- **Near Black** (`#212121`): Standard body link color — slightly softer than pure black.
- **Deep Dark** (`#17171c`): A blue-tinted near-black for navigation and dark-section text.
### Secondary & Accent
- **Interaction Blue** (`#1863dc`): The primary interactive accent — appears on button hover, focus states, and active links. The sole chromatic action color.
- **Ring Blue** (`#4c6ee6` at 50%): Tailwind ring color for keyboard focus indicators.
- **Focus Purple** (`#9b60aa`): Input focus border color — a muted violet.
### Surface & Background
- **Pure White** (`#ffffff`): The primary page background and card surface.
- **Snow** (`#fafafa`): Subtle elevated surfaces and light-section backgrounds.
- **Lightest Gray** (`#f2f2f2`): Card borders and the softest containment lines.
### Neutrals & Text
- **Muted Slate** (`#93939f`): De-emphasized footer links and tertiary text — a cool-toned gray with a slight blue-violet tint.
- **Border Cool** (`#d9d9dd`): Standard section and list-item borders — a cool, slightly purple-tinted gray.
- **Border Light** (`#e5e7eb`): Lighter border variant — Tailwind's standard gray-200.
### Gradient System
- **Purple-Violet Hero Band**: Deep purple gradient sections that create dramatic contrast against the white canvas. These appear as full-width bands housing product screenshots and key messaging.
- **Dark Footer Gradient**: The page transitions through deep purple/charcoal to the black footer, creating a "dusk" effect.
## 3. Typography Rules
### Font Family
- **Display**: `CohereText`, with fallbacks: `Space Grotesk, Inter, ui-sans-serif, system-ui`
- **Body / UI**: `Unica77 Cohere Web`, with fallbacks: `Inter, Arial, ui-sans-serif, system-ui`
- **Code**: `CohereMono`, with fallbacks: `Arial, ui-sans-serif, system-ui`
- **Icons**: `CohereIconDefault` (custom icon font)
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display / Hero | CohereText | 72px (4.5rem) | 400 | 1.00 (tight) | -1.44px | Maximum impact, serif authority |
| Display Secondary | CohereText | 60px (3.75rem) | 400 | 1.00 (tight) | -1.2px | Large section headings |
| Section Heading | Unica77 | 48px (3rem) | 400 | 1.20 (tight) | -0.48px | Feature section titles |
| Sub-heading | Unica77 | 32px (2rem) | 400 | 1.20 (tight) | -0.32px | Card headings, feature names |
| Feature Title | Unica77 | 24px (1.5rem) | 400 | 1.30 | normal | Smaller section titles |
| Body Large | Unica77 | 18px (1.13rem) | 400 | 1.40 | normal | Intro paragraphs |
| Body / Button | Unica77 | 16px (1rem) | 400 | 1.50 | normal | Standard body, button text |
| Button Medium | Unica77 | 14px (0.88rem) | 500 | 1.71 (relaxed) | normal | Smaller buttons, emphasized labels |
| Caption | Unica77 | 14px (0.88rem) | 400 | 1.40 | normal | Metadata, descriptions |
| Uppercase Label | Unica77 / CohereMono | 14px (0.88rem) | 400 | 1.40 | 0.28px | Uppercase section labels |
| Small | Unica77 | 12px (0.75rem) | 400 | 1.40 | normal | Smallest text, footer links |
| Code Micro | CohereMono | 8px (0.5rem) | 400 | 1.40 | 0.16px | Tiny uppercase code labels |
### Principles
- **Serif for declaration, sans for utility**: CohereText carries the brand voice at display scale — its serif terminals give headlines the authority of published research. Unica77 handles everything functional with Swiss-geometric neutrality.
- **Negative tracking at scale**: CohereText uses -1.2px to -1.44px letter-spacing at 60–72px, creating dense, impactful text blocks.
- **Single body weight**: Nearly all Unica77 usage is weight 400. Weight 500 appears only for small button emphasis. The system relies on size and spacing, not weight contrast.
- **Uppercase code labels**: CohereMono uses uppercase with positive letter-spacing (0.16–0.28px) for technical tags and section markers.
## 4. Component Stylings
### Buttons
**Ghost / Transparent**
- Background: transparent (`rgba(255, 255, 255, 0)`)
- Text: Cohere Black (`#000000`)
- No border visible
- Hover: text shifts to Interaction Blue (`#1863dc`), opacity 0.8
- Focus: solid 2px outline in Interaction Blue
- The primary button style — invisible until interacted with
**Dark Solid**
- Background: dark/black
- Text: Pure White
- For CTA on light surfaces
- Pill-shaped or standard radius
**Outlined**
- Border-based containment
- Used in secondary actions
### Cards & Containers
- Background: Pure White (`#ffffff`)
- Border: thin solid Lightest Gray (`1px solid #f2f2f2`) for subtle cards; Cool Border (`#d9d9dd`) for emphasized
- Radius: **22px** — the signature Cohere radius for primary cards, images, and dialog containers. Also 4px, 8px, 16px, 20px for smaller elements
- Shadow: minimal — Cohere relies on background color and borders rather than shadows
- Special: `0px 0px 22px 22px` radius (bottom-only rounding) for section containers
- Dialog: 8px radius for modal/dialog boxes
### Inputs & Forms
- Text: white on dark input, black on light
- Focus border: Focus Purple (`#9b60aa`) with `1px solid`
- Focus shadow: red ring (`rgb(179, 0, 0) 0px 0px 0px 2px`) — likely for error state indication
- Focus outline: Interaction Blue solid 2px
### Navigation
- Clean horizontal nav on white or dark background
- Logo: Cohere wordmark (custom SVG)
- Links: Dark text at 16px Unica77
- CTA: Dark solid button
- Mobile: hamburger collapse
### Image Treatment
- Enterprise photography with diverse subjects and environments
- Purple-tinted hero photography for dramatic sections
- Product UI screenshots on dark surfaces
- Images with 22px radius matching card system
- Full-bleed purple gradient sections
### Distinctive Components
**22px Card System**
- The 22px border-radius is Cohere's visual signature
- All primary cards, images, and containers use this radius
- Creates a cloud-like, organic softness that's distinctive from the typical 8–12px
**Enterprise Trust Bar**
- Company logos displayed in a horizontal strip
- Demonstrates enterprise adoption
- Clean, monochrome logo treatment
**Purple Hero Bands**
- Full-width deep purple sections housing product showcases
- Create dramatic visual breaks in the white page flow
- Product screenshots float within the purple environment
**Uppercase Code Tags**
- CohereMono in uppercase with letter-spacing
- Used as section markers and categorization labels
- Creates a technical, structured information hierarchy
## 5. Layout Principles
### Spacing System
- Base unit: 8px
- Scale: 2px, 6px, 8px, 10px, 12px, 16px, 20px, 22px, 24px, 28px, 32px, 36px, 40px, 56px, 60px
- Button padding varies by variant
- Card internal padding: approximately 24–32px
- Section vertical spacing: generous (56–60px between sections)
### Grid & Container
- Max container width: up to 2560px (very wide) with responsive scaling
- Hero: centered with dramatic typography
- Feature sections: multi-column card grids
- Enterprise sections: full-width purple bands
- 26 breakpoints detected — extremely granular responsive system
### Whitespace Philosophy
- **Enterprise clarity**: Each section presents one clear proposition with breathing room between.
- **Photography as hero**: Large photographic sections provide visual interest without requiring decorative design elements.
- **Card grouping**: Related content is grouped into 22px-rounded cards, creating natural information clusters.
### Border Radius Scale
- Sharp (4px): Navigation elements, small tags, pagination
- Comfortable (8px): Dialog boxes, secondary containers, small cards
- Generous (16px): Featured containers, medium cards
- Large (20px): Large feature cards
- Signature (22px): Primary cards, hero images, main containers — THE Cohere radius
- Pill (9999px): Buttons, tags, status indicators
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow, no border | Page background, text blocks |
| Bordered (Level 1) | `1px solid #f2f2f2` or `#d9d9dd` | Standard cards, list separators |
| Purple Band (Level 2) | Full-width dark purple background | Hero sections, feature showcases |
**Shadow Philosophy**: Cohere is nearly shadow-free. Depth is communicated through **background color contrast** (white cards on purple bands, white surface on snow), **border containment** (cool gray borders), and the dramatic **light-to-dark section alternation**. When elements need elevation, they achieve it through being white-on-dark rather than through shadow casting.
## 7. Do's and Don'ts
### Do
- Use 22px border-radius on all primary cards and containers — it's the visual signature
- Use CohereText for display headings (72px, 60px) with negative letter-spacing
- Use Unica77 for all body and UI text at weight 400
- Keep the palette black-and-white with cool gray borders
- Use Interaction Blue (#1863dc) only for hover/focus interactive states
- Use deep purple sections for dramatic visual breaks and product showcases
- Apply uppercase + letter-spacing on CohereMono for section labels
- Maintain enterprise-appropriate photography with diverse subjects
### Don't
- Don't use border-radius other than 22px on primary cards — the signature radius matters
- Don't introduce warm colors — the palette is strictly cool-toned
- Don't use heavy shadows — depth comes from color contrast and borders
- Don't use bold (700+) weight on body text — 400–500 is the range
- Don't skip the serif/sans hierarchy — CohereText for headlines, Unica77 for body
- Don't use purple as a surface color for cards — purple is reserved for full-width sections
- Don't reduce section spacing below 40px — enterprise layouts need breathing room
- Don't use decoration on buttons by default — ghost/transparent is the base state
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Small Mobile | <425px | Compact layout, minimal spacing |
| Mobile | 425–640px | Single column, stacked cards |
| Large Mobile | 640–768px | Minor spacing adjustments |
| Tablet | 768–1024px | 2-column grids begin |
| Desktop | 1024–1440px | Full multi-column layout |
| Large Desktop | 1440–2560px | Maximum container width |
*26 breakpoints detected — one of the most granularly responsive sites in the dataset.*
### Touch Targets
- Buttons adequately sized for touch interaction
- Navigation links with comfortable spacing
- Card surfaces as touch targets
### Collapsing Strategy
- **Navigation**: Full nav collapses to hamburger
- **Feature grids**: Multi-column → 2-column → single column
- **Hero text**: 72px → 48px → 32px progressive scaling
- **Purple sections**: Maintain full-width, content stacks
- **Card grids**: 3 → 2 → 1 column
### Image Behavior
- Photography scales proportionally within 22px-radius containers
- Product screenshots maintain aspect ratio
- Purple sections scale background proportionally
## 9. Agent Prompt Guide
### Quick Color Reference
- Primary Text: "Cohere Black (#000000)"
- Page Background: "Pure White (#ffffff)"
- Secondary Text: "Near Black (#212121)"
- Hover Accent: "Interaction Blue (#1863dc)"
- Muted Text: "Muted Slate (#93939f)"
- Card Borders: "Lightest Gray (#f2f2f2)"
- Section Borders: "Border Cool (#d9d9dd)"
### Example Component Prompts
- "Create a hero section on Pure White (#ffffff) with CohereText at 72px weight 400, line-height 1.0, letter-spacing -1.44px. Cohere Black text. Subtitle in Unica77 at 18px weight 400, line-height 1.4."
- "Design a feature card with 22px border-radius, 1px solid Lightest Gray (#f2f2f2) border on white. Title in Unica77 at 32px, letter-spacing -0.32px. Body in Unica77 at 16px, Muted Slate (#93939f)."
- "Build a ghost button: transparent background, Cohere Black text in Unica77 at 16px. On hover, text shifts to Interaction Blue (#1863dc) with 0.8 opacity. Focus: 2px solid Interaction Blue outline."
- "Create a deep purple full-width section with white text. CohereText at 60px for the heading. Product screenshot floats within using 22px border-radius."
- "Design a section label using CohereMono at 14px, uppercase, letter-spacing 0.28px. Muted Slate (#93939f) text."
### Iteration Guide
1. Focus on ONE component at a time
2. Always use 22px radius for primary cards — "the Cohere card roundness"
3. Specify the typeface — CohereText for headlines, Unica77 for body, CohereMono for labels
4. Interactive elements use Interaction Blue (#1863dc) on hover only
5. Keep surfaces white with cool gray borders — no warm tones
6. Purple is for full-width sections, never card backgrounds

# Design System Inspired by Coinbase
> Category: Fintech & Crypto
> Crypto exchange. Clean blue identity, trust-focused, institutional feel.
## 1. Visual Theme & Atmosphere
Coinbase's website is a clean, trustworthy crypto platform that communicates financial reliability through a blue-and-white binary palette. The design uses Coinbase Blue (`#0052ff`) — a deep, saturated blue — as the singular brand accent against white and near-black surfaces. The proprietary font family includes CoinbaseDisplay for hero headlines, CoinbaseSans for UI text, CoinbaseText for body reading, and CoinbaseIcons for iconography — a comprehensive four-font system.
The button system uses a distinctive 56px radius for pill-shaped CTAs with hover transitions to a lighter blue (`#578bfa`). The design alternates between white content sections and dark (`#0a0b0d`, `#282b31`) feature sections, creating a professional, financial-grade interface.
**Key Characteristics:**
- Coinbase Blue (`#0052ff`) as singular brand accent
- Four-font proprietary family: Display, Sans, Text, Icons
- 56px radius pill buttons with blue hover transition
- Near-black (`#0a0b0d`) dark sections + white light sections

# Design System Inspired by Colorful
> Category: Bold & Expressive
> Vibrant, high-contrast palettes and gradients for engaging, memorable, and modern user experiences.
## 1. Visual Theme & Atmosphere
Vibrant, high-contrast palettes and gradients for engaging, memorable, and modern user experiences.
- **Visual style:** high-contrast, playful, premium
- **Color stance:** primary, neutral, success, warning, danger
- **Design intent:** Keep outputs recognizable to this style family while preserving usability and readability.
## 2. Color
- **Primary:** `#3B82F6` — Token from style foundations.
- **Secondary:** `#8B5CF6` — Token from style foundations.
- **Success:** `#16A34A` — Token from style foundations.
- **Warning:** `#D97706` — Token from style foundations.
- **Danger:** `#DC2626` — Token from style foundations.
- **Surface:** `#FFFFFF` — Token from style foundations.
- **Text:** `#111827` — Token from style foundations.
- **Neutral:** `#FFFFFF` — Derived from the surface token for official format compatibility.
- Favor Primary (#3B82F6) for CTA emphasis.
- Use Surface (#FFFFFF) for large backgrounds and cards.
- Keep body copy on Text (#111827) for legibility.
## 3. Typography
- **Scale:** 12/14/16/20/24/32
- **Families:** primary=Inter, display=Inter, mono=JetBrains Mono
- **Weights:** 100, 200, 300, 400, 500, 600, 700, 800, 900
- Headings should carry the style personality; body text should optimize scanability and contrast.
## 4. Spacing & Grid
- **Spacing scale:** 8pt baseline grid
- Keep vertical rhythm consistent across sections and components.
- Align columns and modules to a predictable grid; avoid ad-hoc offsets.
## 5. Layout & Composition
- Prefer clear content blocks with consistent internal padding.
- Keep hierarchy obvious: headline → support text → primary action.
- Use whitespace to separate concerns before adding borders or shadows.
## 6. Components
- Buttons: primary action uses `#3B82F6`; secondary actions stay neutral.
- Inputs: strong focus-visible states, clear labels, and predictable error messaging.
- Cards/sections: use consistent radii, spacing, and elevation strategy across the page.
## 7. Motion & Interaction
- Use subtle transitions that emphasize Primary (#3B82F6) as the interaction signal.
- Default to short, purposeful transitions (150–250ms) with stable easing.
- Ensure hover, focus-visible, active, disabled, and loading states are explicit.
## 8. Voice & Brand
- Tone should reflect the visual style: concise, confident, and product-specific.
- Keep microcopy action-oriented and avoid generic filler language.
- Preserve the style identity in headlines while keeping UI labels literal and clear.
## 9. Anti-patterns

# Design System Inspired by Composio
> Category: Backend & Data
> Tool integration platform. Modern dark with colorful integration icons.
## 1. Visual Theme & Atmosphere
Composio's interface is a nocturnal command center — a dense, developer-focused darkness punctuated by electric cyan and deep cobalt signals. The entire experience is built on an almost-pure-black canvas (`#0f0f0f`) where content floats within barely-visible containment borders, creating the feeling of a high-tech control panel rather than a traditional marketing page. It's a site that whispers authority to developers who live in dark terminals.
The visual language leans heavily into the aesthetic of code editors and terminal windows. JetBrains Mono appears alongside the geometric precision of abcDiatype, reinforcing the message that this is a tool built *by* developers *for* developers. Decorative elements are restrained but impactful — subtle cyan-blue gradient glows emanate from cards and sections like bioluminescent organisms in deep water, while hard-offset shadows (`4px 4px`) on select elements add a raw, brutalist edge that prevents the design from feeling sterile.
What makes Composio distinctive is its tension between extreme minimalism and strategic bursts of luminous color. The site never shouts — headings use tight line-heights (0.87) that compress text into dense, authoritative blocks. Color is rationed like a rare resource: white text for primary content, semi-transparent white (`rgba(255,255,255,0.5-0.6)`) for secondary, and brand blue (`#0007cd`) or electric cyan (`#00ffff`) reserved exclusively for interactive moments and accent glows.
**Key Characteristics:**
- Pitch-black canvas with near-invisible white-border containment (4-12% opacity)
- Dual-font identity: geometric sans-serif (abcDiatype) for content, monospace (JetBrains Mono) for technical credibility
- Ultra-tight heading line-heights (0.87-1.0) creating compressed, impactful text blocks
- Bioluminescent accent strategy — cyan and blue glows that feel like they're emitting light from within
- Hard-offset brutalist shadows (`4px 4px`) on select interactive elements
- Monochrome hierarchy with color used only at the highest-signal moments
- Developer-terminal aesthetic that bridges marketing and documentation
## 2. Color Palette & Roles
### Primary
- **Composio Cobalt** (`#0007cd`): The core brand color — a deep, saturated blue used sparingly for high-priority interactive elements and brand moments. It anchors the identity with quiet intensity.
### Secondary & Accent
- **Electric Cyan** (`#00ffff`): The attention-grabbing accent — used at low opacity (`rgba(0,255,255,0.12)`) for glowing button backgrounds and card highlights. At full saturation, it serves as the energetic counterpoint to the dark canvas.
- **Signal Blue** (`#0089ff` / `rgb(0,137,255)`): Used for select button borders and interactive focus states, bridging the gap between Cobalt and Cyan.
- **Ocean Blue** (`#0096ff` / `rgb(0,150,255)`): Accent border color on CTA buttons, slightly warmer than Signal Blue.
### Surface & Background
- **Void Black** (`#0f0f0f`): The primary page background — not pure black, but a hair warmer, reducing eye strain on dark displays.
- **Pure Black** (`#000000`): Used for card interiors and deep-nested containers, creating a subtle depth distinction from the page background.
- **Charcoal** (`#2c2c2c` / `rgb(44,44,44)`): Used for secondary button borders and divider lines on dark surfaces.
### Neutrals & Text
- **Pure White** (`#ffffff`): Primary heading and high-emphasis text color on dark surfaces.
- **Muted Smoke** (`#444444`): De-emphasized body text, metadata, and tertiary content.
- **Ghost White** (`rgba(255,255,255,0.6)`): Secondary body text and link labels — visible but deliberately receded.
- **Whisper White** (`rgba(255,255,255,0.5)`): Tertiary button text and placeholder content.
- **Phantom White** (`rgba(255,255,255,0.2)`): Subtle button backgrounds and deeply receded UI chrome.
### Semantic & Accent
- **Border Mist 12** (`rgba(255,255,255,0.12)`): Highest-opacity border treatment — used for prominent card edges and content separators.
- **Border Mist 10** (`rgba(255,255,255,0.10)`): Standard container borders on dark surfaces.
- **Border Mist 08** (`rgba(255,255,255,0.08)`): Subtle section dividers and secondary card edges.
- **Border Mist 06** (`rgba(255,255,255,0.06)`): Near-invisible containment borders for background groupings.
- **Border Mist 04** (`rgba(255,255,255,0.04)`): The faintest border — used for atmospheric separation only.
- **Light Border** (`#e0e0e0` / `rgb(224,224,224)`): Reserved for light-surface contexts (rare on this site).
### Gradient System
- **Cyan Glow**: Radial gradients using `#00ffff` at very low opacity, creating bioluminescent halos behind cards and feature sections.
- **Blue-to-Black Fade**: Linear gradients from Composio Cobalt (`#0007cd`) fading into Void Black (`#0f0f0f`), used in hero backgrounds and section transitions.
- **White Fog**: Bottom-of-page gradient transitioning from dark to a diffused white/gray, creating an atmospheric "horizon line" effect near the footer.
## 3. Typography Rules
### Font Family
- **Primary**: `abcDiatype`, with fallbacks: `abcDiatype Fallback, ui-sans-serif, system-ui, Apple Color Emoji, Segoe UI Emoji, Segoe UI Symbol, Noto Color Emoji`
- **Monospace**: `JetBrains Mono`, with fallbacks: `JetBrains Mono Fallback, ui-monospace, SFMono-Regular, Menlo, Monaco, Consolas, Liberation Mono, Courier New`
- **System Monospace** (fallback): `Menlo`, `monospace` for smallest inline code
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display / Hero | abcDiatype | 64px (4rem) | 400 | 0.87 (ultra-tight) | normal | Massive, compressed headings |
| Section Heading | abcDiatype | 48px (3rem) | 400 | 1.00 (tight) | normal | Major feature section titles |
| Sub-heading Large | abcDiatype | 40px (2.5rem) | 400 | 1.00 (tight) | normal | Secondary section markers |
| Sub-heading | abcDiatype | 28px (1.75rem) | 400 | 1.20 (tight) | normal | Card titles, feature names |
| Card Title | abcDiatype | 24px (1.5rem) | 500 | 1.20 (tight) | normal | Medium-emphasis card headings |
| Feature Label | abcDiatype | 20px (1.25rem) | 500 | 1.20 (tight) | normal | Smaller card titles, labels |
| Body Large | abcDiatype | 18px (1.125rem) | 400 | 1.20 (tight) | normal | Intro paragraphs |
| Body / Button | abcDiatype | 16px (1rem) | 400 | 1.50 | normal | Standard body text, nav links, buttons |
| Body Small | abcDiatype | 15px (0.94rem) | 400 | 1.63 (relaxed) | normal | Longer-form body text |
| Caption | abcDiatype | 14px (0.875rem) | 400 | 1.63 (relaxed) | normal | Descriptions, metadata |
| Label | abcDiatype | 13px (0.81rem) | 500 | 1.50 | normal | UI labels, badges |
| Tag / Overline | abcDiatype | 12px (0.75rem) | 500 | 1.00 (tight) | 0.3px | Uppercase overline labels |
| Micro | abcDiatype | 12px (0.75rem) | 400 | 1.00 (tight) | 0.3px | Smallest sans-serif text |
| Code Body | JetBrains Mono | 16px (1rem) | 400 | 1.50 | -0.32px | Inline code, terminal output |
| Code Small | JetBrains Mono | 14px (0.875rem) | 400 | 1.50 | -0.28px | Code snippets, technical labels |
| Code Caption | JetBrains Mono | 12px (0.75rem) | 400 | 1.50 | -0.28px | Small code references |
| Code Overline | JetBrains Mono | 14px (0.875rem) | 400 | 1.43 | 0.7px | Uppercase technical labels |
| Code Micro | JetBrains Mono | 11px (0.69rem) | 400 | 1.33 | 0.55px | Tiny uppercase code tags |
| Code Nano | JetBrains Mono | 9-10px | 400 | 1.33 | 0.45-0.5px | Smallest monospace text |
### Principles
- **Compression creates authority**: Heading line-heights are drastically tight (0.87-1.0), making large text feel dense and commanding rather than airy and decorative.
- **Dual personality**: abcDiatype carries the marketing voice — geometric, precise, friendly. JetBrains Mono carries the technical voice — credible, functional, familiar to developers.
- **Weight restraint**: Almost everything is weight 400 (regular). Weight 500 (medium) is reserved for small labels, badges, and select card titles. Weight 700 (bold) appears only in microscopic system-monospace contexts.
- **Negative letter-spacing on code**: JetBrains Mono uses negative letter-spacing (-0.28px to -0.98px) for dense, compact code blocks that feel like a real IDE.
- **Uppercase is earned**: The `uppercase` + `letter-spacing` treatment is reserved exclusively for tiny overline labels and technical tags — never for headings.
## 4. Component Stylings
### Buttons
**Primary CTA (White Fill)**
- Background: Pure White (`#ffffff`)
- Text: Near Black (`oklch(0.145 0 0)`)
- Padding: comfortable (8px 24px)
- Border: none
- Radius: subtly rounded (likely 4px based on token scale)
- Hover: likely subtle opacity reduction or slight gray shift
**Cyan Accent CTA**
- Background: Electric Cyan at 12% opacity (`rgba(0,255,255,0.12)`)
- Text: Near Black (`oklch(0.145 0 0)`)
- Padding: comfortable (8px 24px)
- Border: thin solid Ocean Blue (`1px solid rgb(0,150,255)`)
- Radius: subtly rounded (4px)
- Creates a "glowing from within" effect on dark backgrounds
**Ghost / Outline (Signal Blue)**
- Background: transparent
- Text: Near Black (`oklch(0.145 0 0)`)
- Padding: balanced (10px)
- Border: thin solid Signal Blue (`1px solid rgb(0,137,255)`)
- Hover: likely fill or border color shift
**Ghost / Outline (Charcoal)**
- Background: transparent
- Text: Near Black (`oklch(0.145 0 0)`)
- Padding: balanced (10px)
- Border: thin solid Charcoal (`1px solid rgb(44,44,44)`)
- For secondary/tertiary actions on dark surfaces
**Phantom Button**
- Background: Phantom White (`rgba(255,255,255,0.2)`)
- Text: Whisper White (`rgba(255,255,255,0.5)`)
- No visible border
- Used for deeply de-emphasized actions
### Cards & Containers
- Background: Pure Black (`#000000`) or transparent
- Border: white at very low opacity, ranging from Border Mist 04 (`rgba(255,255,255,0.04)`) to Border Mist 12 (`rgba(255,255,255,0.12)`) depending on prominence
- Radius: barely rounded corners (2px for inline elements, 4px for content cards)
- Shadow: select cards use the hard-offset brutalist shadow (`rgba(0,0,0,0.15) 4px 4px 0px 0px`) — a distinctive design choice that adds raw depth
- Elevation shadow: deeper containers use soft diffuse shadow (`rgba(0,0,0,0.5) 0px 8px 32px`)
- Hover behavior: likely subtle border opacity increase or faint glow effect
### Inputs & Forms
- No explicit input token data extracted — inputs likely follow the dark-surface pattern with:
- Background: transparent or Pure Black
- Border: Border Mist 10 (`rgba(255,255,255,0.10)`)
- Focus: border shifts to Signal Blue (`#0089ff`) or Electric Cyan
- Text: Pure White with Ghost White placeholder
### Navigation
- Sticky top nav bar on dark/black background
- Logo (white SVG): Composio wordmark on the left
- Nav links: Pure White (`#ffffff`) at standard body size (16px, abcDiatype)
- CTA button in the nav: White Fill Primary style
- Mobile: collapses to hamburger menu, single-column layout
- Subtle bottom border on nav (Border Mist 06-08)
### Image Treatment
- Dark-themed product screenshots and UI mockups dominate
- Images sit within bordered containers matching the card system
- Blue/cyan gradient glows behind or beneath feature images
- No visible border-radius on images beyond container rounding (4px)
- Full-bleed within their card containers
### Distinctive Components
**Stats/Metrics Display**
- Large monospace numbers (JetBrains Mono) — "10k+" style
- Tight layout with subtle label text beneath
**Code Blocks / Terminal Previews**
- Dark containers with JetBrains Mono
- Syntax-highlighted content
- Subtle bordered containers (Border Mist 10)
**Integration/Partner Logos Grid**
- Grid layout of tool logos on dark surface
- Contained within bordered card
- Demonstrates ecosystem breadth
**"COMPOSIO" Brand Display**
- Oversized brand typography — likely the largest text on the page
- Used as a section divider/brand statement
- Stark white on black
## 5. Layout Principles
### Spacing System
- Base unit: 8px
- Scale: 1px, 2px, 4px, 6px, 8px, 10px, 12px, 14px, 16px, 18px, 20px, 24px, 30px, 32px, 40px
- Component padding: typically 10px (buttons) to 24px (CTA buttons horizontal)
- Section padding: generous vertical spacing (estimated 80-120px between major sections)
- Card internal padding: approximately 24-32px
### Grid & Container
- Max container width: approximately 1200px, centered
- Content sections use single-column or 2-3 column grids for feature cards
- Hero: centered single-column with maximum impact
- Feature sections: asymmetric layouts mixing text blocks with product screenshots
### Whitespace Philosophy
- **Breathing room between sections**: Large vertical gaps create distinct "chapters" in the page scroll.
- **Dense within components**: Cards and text blocks are internally compact (tight line-heights, minimal internal padding), creating focused information nodes.
- **Contrast-driven separation**: Rather than relying solely on whitespace, Composio uses border opacity differences and subtle background shifts to delineate content zones.
### Border Radius Scale
- Nearly squared (2px): Inline code spans, small tags, pre blocks — the sharpest treatment, conveying technical precision
- Subtly rounded (4px): Content cards, images, standard containers — the workhorse radius
- Pill-shaped (37px): Select buttons and badges — creates a softer, more approachable feel for key CTAs
- Full round (9999px+): Circular elements, avatar-like containers, decorative dots
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow, no border | Page background, inline text |
| Contained (Level 1) | Border Mist 04-08, no shadow | Background groupings, subtle sections |
| Card (Level 2) | Border Mist 10-12, no shadow | Standard content cards, code blocks |
| Brutalist (Level 3) | Hard offset shadow (`4px 4px`, 15% black) | Select interactive cards, distinctive feature highlights |
| Floating (Level 4) | Soft diffuse shadow (`0px 8px 32px`, 50% black) | Modals, overlays, deeply elevated content |
**Shadow Philosophy**: Composio uses shadows sparingly and with deliberate contrast. The hard-offset brutalist shadow is the signature — it breaks the sleek darkness with a raw, almost retro-computing feel. The soft diffuse shadow is reserved for truly floating elements. Most depth is communicated through border opacity gradations rather than shadows.
### Decorative Depth
- **Cyan Glow Halos**: Radial gradient halos using Electric Cyan at low opacity behind feature cards and images. Creates a "screen glow" effect as if the UI elements are emitting light.
- **Blue-Black Gradient Washes**: Linear gradients from Composio Cobalt to Void Black used as section backgrounds, adding subtle color temperature shifts.
- **White Fog Horizon**: A gradient from dark to diffused white/gray at the bottom of the page, creating an atmospheric "dawn" effect before the footer.
## 7. Do's and Don'ts
### Do
- Use Void Black (`#0f0f0f`) as the primary page background — never pure white for main surfaces
- Keep heading line-heights ultra-tight (0.87-1.0) for compressed, authoritative text blocks
- Use white-opacity borders (4-12%) for containment — they're more important than shadows here
- Reserve Electric Cyan (`#00ffff`) for high-signal moments only — CTAs, glows, interactive accents
- Pair abcDiatype with JetBrains Mono to reinforce the developer-tool identity
- Use the hard-offset shadow (`4px 4px`) intentionally on select elements for brutalist personality
- Keep button text dark (`oklch(0.145 0 0)`) even on the darkest backgrounds — buttons carry their own surface
- Layer opacity-based borders to create subtle depth without shadows
- Use uppercase + letter-spacing only for tiny overline labels (12px or smaller)
### Don't
- Don't use bright backgrounds or light surfaces as primary containers
- Don't apply heavy shadows everywhere — depth comes from border opacity, not box-shadow
- Don't use Composio Cobalt (`#0007cd`) as a text color — it's too dark on dark and too saturated on light
- Don't increase heading line-heights beyond 1.2 — the compressed feel is core to the identity
- Don't use bold (700) weight for body or heading text — 400-500 is the ceiling
- Don't mix warm colors — the palette is strictly cool (blue, cyan, white, black)
- Don't use border-radius larger than 4px on content cards — the precision of near-square corners is intentional
- Don't place Electric Cyan at full opacity on large surfaces — it's an accent, used at 12% max for backgrounds
- Don't use decorative serif or handwritten fonts — the entire identity is geometric sans + monospace
- Don't skip the monospace font for technical content — JetBrains Mono is not decorative, it's a credibility signal
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | <768px | Single column, hamburger nav, full-width cards, reduced section padding, hero text scales down to ~28-40px |
| Tablet | 768-1024px | 2-column grid for cards, condensed nav, slightly reduced hero text |
| Desktop | 1024-1440px | Full multi-column layout, expanded nav with all links visible, large hero typography (64px) |
| Large Desktop | >1440px | Max-width container centered, generous horizontal margins |
### Touch Targets
- Minimum touch target: 44x44px for all interactive elements
- Buttons use comfortable padding (8px 24px minimum) ensuring adequate touch area
- Nav links spaced with sufficient gap for thumb navigation
### Collapsing Strategy
- **Navigation**: Full horizontal nav on desktop collapses to hamburger on mobile
- **Feature grids**: 3-column → 2-column → single-column stacking
- **Hero text**: 64px → 40px → 28px progressive scaling
- **Section padding**: Reduces proportionally but maintains generous vertical rhythm
- **Cards**: Stack vertically on mobile with full-width treatment
- **Code blocks**: Horizontal scroll on smaller viewports rather than wrapping
### Image Behavior
- Product screenshots scale proportionally within their containers
- Dark-themed images maintain contrast on the dark background at all sizes
- Gradient glow effects scale with container size
- No visible art direction changes between breakpoints — same crops, proportional scaling
## 9. Agent Prompt Guide
### Quick Color Reference
- Primary CTA: "Pure White (#ffffff)"
- Page Background: "Void Black (#0f0f0f)"
- Brand Accent: "Composio Cobalt (#0007cd)"
- Glow Accent: "Electric Cyan (#00ffff)"
- Heading Text: "Pure White (#ffffff)"
- Body Text: "Ghost White (rgba(255,255,255,0.6))"
- Card Border: "Border Mist 10 (rgba(255,255,255,0.10))"
- Button Border: "Signal Blue (#0089ff)"
### Example Component Prompts
- "Create a feature card with a near-black background (#000000), barely visible white border at 10% opacity, subtly rounded corners (4px), and a hard-offset shadow (4px right, 4px down, 15% black). Use Pure White for the title in abcDiatype at 24px weight 500, and Ghost White (60% opacity) for the description at 16px."
- "Design a primary CTA button with a solid white background, near-black text, comfortable padding (8px vertical, 24px horizontal), and subtly rounded corners. Place it next to a secondary button with transparent background, Signal Blue border, and matching padding."
- "Build a hero section on Void Black (#0f0f0f) with a massive heading at 64px, line-height 0.87, in abcDiatype. Center the text. Add a subtle blue-to-black gradient glow behind the content. Include a white CTA button and a cyan-accented secondary button below."
- "Create a code snippet display using JetBrains Mono at 14px with -0.28px letter-spacing on a black background. Add a Border Mist 10 border (rgba(255,255,255,0.10)) and 4px radius. Show syntax-highlighted content with white and cyan text."
- "Design a navigation bar on Void Black with the Composio wordmark in white on the left, 4-5 nav links in white abcDiatype at 16px, and a white-fill CTA button on the right. Add a Border Mist 06 bottom border."
### Iteration Guide
When refining existing screens generated with this design system:
1. Focus on ONE component at a time
2. Reference specific color names and hex codes from this document — "use Ghost White (rgba(255,255,255,0.6))" not "make it lighter"
3. Use natural language descriptions — "make the border barely visible" = Border Mist 04-06
4. Describe the desired "feel" alongside specific measurements — "compressed and authoritative heading at 48px with line-height 1.0"
5. For glow effects, specify "Electric Cyan at 12% opacity as a radial gradient behind the element"
6. Always specify which font — abcDiatype for marketing, JetBrains Mono for technical/code content

- Align columns and modules to a predictable grid; avoid ad-hoc offsets.
## 5. Layout & Composition
- Prefer clear content blocks with consistent internal padding.
- Keep hierarchy obvious: headline → support text → primary action.
- Use whitespace to separate concerns before adding borders or shadows.
## 6. Components
- Buttons: primary action uses `#3B82F6`; secondary actions stay neutral.
- Inputs: strong focus-visible states, clear labels, and predictable error messaging.
- Cards/sections: use consistent radii, spacing, and elevation strategy across the page.
## 7. Motion & Interaction
- Use subtle transitions that emphasize Primary (#3B82F6) as the interaction signal.
- Default to short, purposeful transitions (150–250ms) with stable easing.
- Ensure hover, focus-visible, active, disabled, and loading states are explicit.
## 8. Voice & Brand
- Tone should reflect the visual style: concise, confident, and product-specific.
- Keep microcopy action-oriented and avoid generic filler language.
- Preserve the style identity in headlines while keeping UI labels literal and clear.
## 9. Anti-patterns
- Do not introduce off-palette colors when an existing token can solve the problem.
- Do not flatten hierarchy by using the same type size/weight for all text.
- Do not add decorative effects that reduce readability or accessibility.
- Do not mix unrelated visual metaphors in the same interface.

# Design System Inspired by Cursor
> Category: Developer Tools
> AI-first code editor. Sleek dark interface, gradient accents.
## 1. Visual Theme & Atmosphere
Cursor's website is a study in warm minimalism meets code-editor elegance. The entire experience is built on a warm off-white canvas (`#f2f1ed`) with dark warm-brown text (`#26251e`) -- not pure black, not neutral gray, but a deeply warm near-black with a yellowish undertone that evokes old paper, ink, and craft. This warmth permeates every surface: backgrounds lean toward cream (`#e6e5e0`, `#ebeae5`), borders dissolve into transparent warm overlays using `oklab` color space, and even the error state (`#cf2d56`) carries warmth rather than clinical red. The result feels more like a premium print publication than a tech website.
The custom CursorGothic font is the typographic signature -- a gothic sans-serif with aggressive negative letter-spacing at display sizes (-2.16px at 72px) that creates a compressed, engineered feel. As a secondary voice, the jjannon serif font (with OpenType `"cswh"` contextual swash alternates) provides literary counterpoint for body copy and editorial passages. The monospace voice comes from berkeleyMono, a refined coding font that connects the marketing site to Cursor's core identity as a code editor. This three-font system (gothic display, serif body, mono code) gives Cursor one of the most typographically rich palettes in developer tooling.
The border system is particularly distinctive -- Cursor uses `oklab()` color space for border colors, applying warm brown at various alpha levels (0.1, 0.2, 0.55) to create borders that feel organic rather than mechanical. The signature border color `oklab(0.263084 -0.00230259 0.0124794 / 0.1)` is not a simple rgba value but a perceptually uniform color that maintains visual consistency across different backgrounds.
**Key Characteristics:**
- CursorGothic with aggressive negative letter-spacing (-2.16px at 72px, -0.72px at 36px) for compressed display headings
- jjannon serif for body text with OpenType `"cswh"` (contextual swash alternates)
- berkeleyMono for code and technical labels
- Warm off-white background (`#f2f1ed`) instead of pure white -- the entire system is warm-shifted
- Primary text color `#26251e` (warm near-black with yellow undertone)
- Accent orange `#f54e00` for brand highlight and links
- oklab-space borders at various alpha levels for perceptually uniform edge treatment
- Pill-shaped elements with extreme radius (33.5M px, effectively full-pill)
- 8px base spacing system with fine-grained sub-8px increments (1.5px, 2px, 2.5px, 3px, 4px, 5px, 6px)
## 2. Color Palette & Roles
### Primary
- **Cursor Dark** (`#26251e`): Primary text, headings, dark UI surfaces. A warm near-black with distinct yellow-brown undertone -- the defining color of the system.
- **Cursor Cream** (`#f2f1ed`): Page background, primary surface. Not white but a warm cream that sets the entire warm tone.
- **Cursor Light** (`#e6e5e0`): Secondary surface, button backgrounds, card fills. A slightly warmer, slightly darker cream.
- **Pure White** (`#ffffff`): Used sparingly for maximum contrast elements and specific surface highlights.
- **True Black** (`#000000`): Minimal use, specific code/console contexts.
### Accent
- **Cursor Orange** (`#f54e00`): Brand accent, `--color-accent`. A vibrant red-orange used for primary CTAs, active links, and brand moments. Warm and urgent.
- **Gold** (`#c08532`): Secondary accent, warm gold for premium or highlighted contexts.
### Semantic
- **Error** (`#cf2d56`): `--color-error`. A warm crimson-rose rather than cold red.
- **Success** (`#1f8a65`): `--color-success`. A muted teal-green, warm-shifted.
### Timeline / Feature Colors
- **Thinking** (`#dfa88f`): Warm peach for "thinking" state in AI timeline.
- **Grep** (`#9fc9a2`): Soft sage green for search/grep operations.
- **Read** (`#9fbbe0`): Soft blue for file reading operations.
- **Edit** (`#c0a8dd`): Soft lavender for editing operations.
### Surface Scale
- **Surface 100** (`#f7f7f4`): Lightest button/card surface, barely tinted.
- **Surface 200** (`#f2f1ed`): Primary page background.
- **Surface 300** (`#ebeae5`): Button default background, subtle emphasis.
- **Surface 400** (`#e6e5e0`): Card backgrounds, secondary surfaces.
- **Surface 500** (`#e1e0db`): Tertiary button background, deeper emphasis.
### Border Colors
- **Border Primary** (`oklab(0.263084 -0.00230259 0.0124794 / 0.1)`): Standard border, 10% warm brown in oklab space.
- **Border Medium** (`oklab(0.263084 -0.00230259 0.0124794 / 0.2)`): Emphasized border, 20% warm brown.
- **Border Strong** (`rgba(38, 37, 30, 0.55)`): Strong borders, table rules.
- **Border Solid** (`#26251e`): Full-opacity dark border for maximum contrast.
- **Border Light** (`#f2f1ed`): Light border matching page background.
### Shadows & Depth
- **Card Shadow** (`rgba(0,0,0,0.14) 0px 28px 70px, rgba(0,0,0,0.1) 0px 14px 32px, oklab(0.263084 -0.00230259 0.0124794 / 0.1) 0px 0px 0px 1px`): Heavy elevated card with warm oklab border ring.
- **Ambient Shadow** (`rgba(0,0,0,0.02) 0px 0px 16px, rgba(0,0,0,0.008) 0px 0px 8px`): Subtle ambient glow for floating elements.
## 3. Typography Rules

### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display Hero | CursorGothic | 72px (4.50rem) | 400 | 1.10 (tight) | -2.16px | Maximum compression, hero statements |
| Section Heading | CursorGothic | 36px (2.25rem) | 400 | 1.20 (tight) | -0.72px | Feature sections, CTA headlines |
| Sub-heading | CursorGothic | 26px (1.63rem) | 400 | 1.25 (tight) | -0.325px | Card headings, sub-sections |
| Title Small | CursorGothic | 22px (1.38rem) | 400 | 1.30 (tight) | -0.11px | Smaller titles, list headings |
| Body Serif | jjannon | 19.2px (1.20rem) | 500 | 1.50 | normal | Editorial body with `"cswh"` |
| Body Serif SM | jjannon | 17.28px (1.08rem) | 400 | 1.35 | normal | Standard body text, descriptions |
| Body Sans | CursorGothic | 16px (1.00rem) | 400 | 1.50 | normal/0.08px | UI body text |
| Button Label | CursorGothic | 14px (0.88rem) | 400 | 1.00 (tight) | normal | Primary button text |
| Button Caption | CursorGothic | 14px (0.88rem) | 400 | 1.50 | 0.14px | Secondary button with `"ss09"` |
| Caption | CursorGothic | 11px (0.69rem) | 400-500 | 1.50 | normal | Small captions, metadata |
| System Heading | system-ui | 20px (1.25rem) | 700 | 1.55 | normal | System UI headings |
| System Caption | system-ui | 13px (0.81rem) | 500-600 | 1.33 | normal | System UI labels |
| System Micro | system-ui | 11px (0.69rem) | 500 | 1.27 (tight) | 0.048px | Uppercase micro labels |
| Mono Body | berkeleyMono | 12px (0.75rem) | 400 | 1.67 (relaxed) | normal | Code blocks |
| Mono Small | berkeleyMono | 11px (0.69rem) | 400 | 1.33 | -0.275px | Inline code, terminal |
| Lato Heading | Lato | 16px (1.00rem) | 600 | 1.33 | normal | Lato section headings |
| Lato Caption | Lato | 14px (0.88rem) | 400-600 | 1.33 | normal | Lato captions |
| Lato Micro | Lato | 12px (0.75rem) | 400-600 | 1.27 (tight) | 0.053px | Lato small labels |
### Principles
- **Gothic compression for impact**: CursorGothic at display sizes uses -2.16px letter-spacing at 72px, progressively relaxing: -0.72px at 36px, -0.325px at 26px, -0.11px at 22px, normal at 16px and below. The tracking creates a sense of precision engineering.
- **Serif for soul**: jjannon provides literary warmth. The `"cswh"` feature adds contextual swash alternates that give body text a calligraphic quality.
- **Three typographic voices**: Gothic (display/UI), serif (editorial/body), mono (code/technical). Each serves a distinct communication purpose.
- **Weight restraint**: CursorGothic uses weight 400 almost exclusively, relying on size and tracking for hierarchy rather than weight. System-ui components use 500-700 for functional emphasis.

- Links: 14px CursorGothic or system-ui, weight 500
- CTA button: warm surface with Cursor Dark text
- Tab navigation: bottom border `1px solid oklab(0.263 / 0.1)` with active tab differentiation
### Image Treatment
- Code editor screenshots with `1px solid oklab(0.263 / 0.1)` border
- Rounded corners: 8px standard
- AI chat/timeline screenshots dominate feature sections
- Warm gradient or solid cream backgrounds behind hero images
### Distinctive Components

- Vertical timeline showing AI operations: thinking (peach), grep (sage), read (blue), edit (lavender)
- Each step uses its semantic color with matching text
- Connected with vertical lines
- Core visual metaphor for Cursor's AI-first coding experience
**Code Editor Previews**

## 5. Layout Principles
### Spacing System
- Base unit: 8px
- Fine scale: 1.5px, 2px, 2.5px, 3px, 4px, 5px, 6px (sub-8px for micro-adjustments)
- Standard scale: 8px, 10px, 12px, 14px (derived from extraction)
- Extended scale (inferred): 16px, 24px, 32px, 48px, 64px, 96px
- Notable: fine-grained sub-8px increments for precise icon/text alignment
### Grid & Container
- Max content width: approximately 1200px
- Hero: centered single-column with generous top padding (80-120px)
- Feature sections: 2-3 column grids for cards and features
- Full-width sections with warm cream or slightly darker backgrounds
- Sidebar layouts for documentation and settings pages
### Whitespace Philosophy
- **Warm negative space**: The cream background means whitespace has warmth and texture, unlike cold white minimalism. Large empty areas feel cozy rather than clinical.
- **Compressed text, open layout**: Aggressive negative letter-spacing on CursorGothic headlines is balanced by generous surrounding margins. Text is dense; space around it breathes.
- **Section variation**: Alternating surface tones (cream → lighter cream → cream) create subtle section differentiation without harsh boundaries.
### Border Radius Scale
- Micro (1.5px): Fine detail elements
- Small (2px): Inline elements, code spans
- Medium (3px): Small containers, inline badges
- Standard (4px): Cards, images, compact buttons
- Comfortable (8px): Primary buttons, cards, menus
- Featured (10px): Larger containers, featured cards
- Full Pill (33.5M px / 9999px): Pill buttons, tags, badges
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Page background, text blocks |
| Border Ring (Level 1) | `oklab(0.263 / 0.1) 0px 0px 0px 1px` | Standard card/container border (warm oklab) |
| Border Medium (Level 1b) | `oklab(0.263 / 0.2) 0px 0px 0px 1px` | Emphasized borders, active states |
| Ambient (Level 2) | `rgba(0,0,0,0.02) 0px 0px 16px, rgba(0,0,0,0.008) 0px 0px 8px` | Floating elements, subtle glow |
| Elevated Card (Level 3) | `rgba(0,0,0,0.14) 0px 28px 70px, rgba(0,0,0,0.1) 0px 14px 32px, oklab ring` | Modals, popovers, elevated cards |
| Focus | `rgba(0,0,0,0.1) 0px 4px 12px` on button focus | Interactive focus feedback |
**Shadow Philosophy**: Cursor's depth system is built around two ideas. First, borders use perceptually uniform oklab color space rather than rgba, ensuring warm brown borders look consistent across different background tones. Second, elevation shadows use dramatically large blur values (28px, 70px) with moderate opacity (0.14, 0.1), creating a diffused, atmospheric lift rather than hard-edged drop shadows. Cards don't feel like they float above the page -- they feel like the page has gently opened a space for them.
### Decorative Depth
- Warm cream surface variations create subtle tonal depth without shadows
- oklab borders at 10% and 20% create a spectrum of edge definition
- No harsh divider lines -- section separation through background tone shifts and spacing
## 7. Interaction & Motion
### Hover States
- Buttons: text color shifts to `--color-error` (`#cf2d56`) on hover -- a distinctive warm crimson that signals interactivity
- Links: color shift to accent orange (`#f54e00`) or underline decoration with `rgba(38, 37, 30, 0.4)`
- Cards: shadow intensification on hover (ambient → elevated)
### Focus States
- Shadow-based focus: `rgba(0,0,0,0.1) 0px 4px 12px` for depth-based focus indication
- Border focus: `oklab(0.263 / 0.2)` (20% border) for input/form focus
- Consistent warm tone in all focus states -- no cold blue focus rings
### Transitions
- Color transitions: 150ms ease for text/background color changes
- Shadow transitions: 200ms ease for elevation changes
- Transform: subtle scale or translate for interactive feedback
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | <600px | Single column, reduced padding, stacked navigation |
| Tablet Small | 600-768px | 2-column grids begin |
| Tablet | 768-900px | Expanded card grids, sidebar appears |
| Desktop Small | 900-1279px | Full layout forming |
| Desktop | >1279px | Full layout, maximum content width |
### Touch Targets
- Buttons use comfortable padding (6px-14px vertical, 8px-14px horizontal)
- Pill buttons maintain tap-friendly sizing with 3px-10px padding
- Navigation links at 14px with adequate spacing for touch
### Collapsing Strategy
- Hero: 72px CursorGothic → 36px → 26px on smaller screens, maintaining proportional letter-spacing
- Navigation: horizontal links → hamburger menu on mobile
- Feature cards: 3-column → 2-column → single column stacked
- Code editor screenshots: maintain aspect ratio, may shrink with border treatment preserved
- Timeline visualization: horizontal → vertical stacking
- Section spacing: 80px+ → 48px → 32px on mobile
### Image Behavior
- Editor screenshots maintain warm border treatment at all sizes
- AI timeline adapts from horizontal to vertical layout
- Product screenshots use responsive images with consistent border radius
- Full-width hero images scale proportionally
## 9. Agent Prompt Guide
### Quick Color Reference
- Primary CTA background: `#ebeae5` (warm cream button)
- Page background: `#f2f1ed` (warm off-white)
- Text color: `#26251e` (warm near-black)
- Secondary text: `rgba(38, 37, 30, 0.55)` (55% warm brown)
- Accent: `#f54e00` (orange)
- Error/hover: `#cf2d56` (warm crimson)
- Success: `#1f8a65` (muted teal)
- Border: `oklab(0.263084 -0.00230259 0.0124794 / 0.1)` or `rgba(38, 37, 30, 0.1)` as fallback
### Example Component Prompts
- "Create a hero section on `#f2f1ed` warm cream background. Headline at 72px CursorGothic weight 400, line-height 1.10, letter-spacing -2.16px, color `#26251e`. Subtitle at 17.28px jjannon weight 400, line-height 1.35, color `rgba(38,37,30,0.55)`. Primary CTA button (`#ebeae5` bg, 8px radius, 10px 14px padding) with hover text shift to `#cf2d56`."
- "Design a card: `#e6e5e0` background, border `1px solid rgba(38,37,30,0.1)`. Radius 8px. Title at 22px CursorGothic weight 400, letter-spacing -0.11px. Body at 17.28px jjannon weight 400, color `rgba(38,37,30,0.55)`. Use `#f54e00` for link accents."
- "Build a pill tag: `#e6e5e0` background, `rgba(38,37,30,0.6)` text, full-pill radius (9999px), 3px 8px padding, 14px CursorGothic weight 400."
- "Create navigation: sticky `#f2f1ed` background with backdrop-filter blur. 14px system-ui weight 500 for links, `#26251e` text. CTA button right-aligned with `#ebeae5` bg and 8px radius. Bottom border `1px solid rgba(38,37,30,0.1)`."
- "Design an AI timeline showing four steps: Thinking (`#dfa88f`), Grep (`#9fc9a2`), Read (`#9fbbe0`), Edit (`#c0a8dd`). Each step: 14px system-ui label + 16px CursorGothic description + vertical connecting line in `rgba(38,37,30,0.1)`."
### Iteration Guide
1. Always use warm tones -- `#f2f1ed` background, `#26251e` text, never pure white/black for primary surfaces
2. Letter-spacing scales with font size for CursorGothic: -2.16px at 72px, -0.72px at 36px, -0.325px at 26px, normal at 16px
3. Use `rgba(38, 37, 30, alpha)` as a CSS-compatible fallback for oklab borders
4. Three fonts, three voices: CursorGothic (display/UI), jjannon (editorial), berkeleyMono (code)
5. Pill shapes (9999px radius) for tags and filters; 8px radius for primary buttons and cards
6. Hover states use `#cf2d56` text color -- the warm crimson shift is a signature interaction
7. Shadows use large blur values (28px, 70px) for diffused atmospheric depth
8. The sub-8px spacing scale (1.5, 2, 2.5, 3, 4, 5, 6px) is critical for icon/text micro-alignment

# Design System Inspired by Dashboard
> Category: Professional & Corporate
> Dark-themed cloud-platform aesthetic with modular grids, glass-like panels, and strong data hierarchy for productivity dashboards.
## 1. Visual Theme & Atmosphere
Dark-themed cloud-platform aesthetic with modular grids, glass-like panels, and strong data hierarchy for productivity dashboards.
- **Visual style:** modern, clean, cloud-platform aesthetic (Heroku/Vercel/GitHub inspired), dark theme, subtle gradients, soft shadows, glass-like panels, rounded components
- **Color stance:** primary, neutral, success, warning, danger
- **Design intent:** Keep outputs recognizable to this style family while preserving usability and readability.
## 2. Color
- **Primary:** `#0C5CAB` — Token from style foundations.
- **Secondary:** `#0A4A8A` — Token from style foundations.
- **Success:** `#10B981` — Token from style foundations.
- **Warning:** `#F59E0B` — Token from style foundations.
- **Danger:** `#EF4444` — Token from style foundations.
- **Surface:** `#09090B` — Token from style foundations.
- **Text:** `#FAFAFA` — Token from style foundations.
- **Neutral:** `#09090B` — Derived from the surface token for official format compatibility.
- Favor Primary (#0C5CAB) for CTA emphasis.
- Use Surface (#09090B) for large backgrounds and cards.
- Keep body copy on Text (#FAFAFA) for legibility.
## 3. Typography
- **Scale:** 12/14/16/20/24/32
- **Families:** primary=IBM Plex Sans, display=IBM Plex Sans, mono=IBM Plex Sans
- **Weights:** 100, 200, 300, 400, 500, 600, 700, 800, 900
- Headings should carry the style personality; body text should optimize scanability and contrast.
## 4. Spacing & Grid
- **Spacing scale:** 8pt baseline grid
- Keep vertical rhythm consistent across sections and components.
- Align columns and modules to a predictable grid; avoid ad-hoc offsets.
## 5. Layout & Composition
- Prefer clear content blocks with consistent internal padding.
- Keep hierarchy obvious: headline → support text → primary action.
- Use whitespace to separate concerns before adding borders or shadows.
## 6. Components
- Buttons: primary action uses `#0C5CAB`; secondary actions stay neutral.
- Inputs: strong focus-visible states, clear labels, and predictable error messaging.
- Cards/sections: use consistent radii, spacing, and elevation strategy across the page.
## 7. Motion & Interaction
- Use subtle transitions that emphasize Primary (#0C5CAB) as the interaction signal.
- Default to short, purposeful transitions (150–250ms) with stable easing.
- Ensure hover, focus-visible, active, disabled, and loading states are explicit.
## 8. Voice & Brand
- Tone should reflect the visual style: concise, confident, and product-specific.
- Keep microcopy action-oriented and avoid generic filler language.
- Preserve the style identity in headlines while keeping UI labels literal and clear.
## 9. Anti-patterns
- Do not introduce off-palette colors when an existing token can solve the problem.
- Do not flatten hierarchy by using the same type size/weight for all text.
- Do not add decorative effects that reduce readability or accessibility.
- Do not mix unrelated visual metaphors in the same interface.

# Neutral Modern
> Category: Starter
> A clean, product-oriented default. Use when the brief doesn't call for a
> specific mood — good for B2B tools, dashboards, and utility pages.
## Visual Theme & Atmosphere
Calm, functional, quietly confident. No ornament. Content-first, chrome-second.
## Color Palette & Roles
- **Background:** `#FAFAFA`
- **Foreground:** `#111111`
- **Accent:** `#2F6FEB` (cobalt) — primary CTAs, links, one hero element per screen
- **Muted:** `#6B6B6B` — secondary text, captions
- **Border:** `#E5E5E5`
- **Surface:** `#FFFFFF` — cards, modals
- **Success:** `#17A34A`, **Warn:** `#EAB308`, **Danger:** `#DC2626`
Never pure black; never pure white for backgrounds.
## Typography Rules
- **Display / headings:** `'Inter', -apple-system, system-ui, sans-serif`, weight 600
- **Body:** `'Inter', -apple-system, system-ui, sans-serif`, weight 400
- **Mono:** `ui-monospace, 'JetBrains Mono', monospace`
- Scale (px): 12 · 14 · 16 · 20 · 24 · 32 · 48 · 64
- Line-height: 1.5 for body, 1.2 for headings
- Letter-spacing: -0.01em on display sizes ≥32px
## Component Stylings
- **Buttons:** 8px radius, 10px padding-block, 16px padding-inline. Primary = cobalt fill, white label. Secondary = 1px border, transparent fill.
- **Cards:** white, 1px border, 12px radius, 20px internal padding, no shadow by default.
- **Inputs:** 1px border, 8px radius, 10px vertical padding, cobalt border on focus.
- **Links:** cobalt, no underline, underline on hover.
## Layout Principles
- 12-column grid, 1200px max-width, 24px gutters.
- Hero: 40–60vh. Content top-biased, never centered vertically.
- Sections: 80px top+bottom spacing desktop, 48px tablet, 32px phone.
- Use whitespace as the main separator. Dividers only between unrelated top-level sections.
## Depth & Elevation
Two levels only:
- **Flat (0):** default.
- **Raised (1):** dropdowns, modals, floating buttons. 2px y-offset, 8px blur, foreground at 8% opacity.
No neumorphism, no glassmorphism.
## Do's and Don'ts
- ✅ Let whitespace do the work.
- ✅ One accent element per screen.
- ✅ Sentence-case headings by default; title case only for brand names.
- ❌ No gradients (except the accent → accent-at-80% on a hero, sparingly).
- ❌ No drop shadows on inputs.
- ❌ No more than three type sizes on one screen.
## Responsive Behavior
- **Desktop ≥ 1024px:** 12-col grid.
- **Tablet 640–1023px:** 8-col grid, 16px gutters.
- **Phone < 640px:** 4-col grid, 12px gutters; hero drops to 40vh.
## Agent Prompt Guide
- When in doubt, subtract. Fewer boxes, less chrome, more space.
- Use the accent color sparingly — at most one hero accent and one CTA accent per screen.
- Do not invent hex values outside this palette. If the request needs one, surface a warning comment in the artifact and use the closest existing token.

# Design System Inspired by Discord
> Category: Productivity & SaaS
> Voice / chat platform. Deep blurple, dark-first surfaces, playful accent moments.
## 1. Visual Theme & Atmosphere
Discord's product is engineered for evenings, raids, and group voice — so the entire surface is dark-first. The default canvas is the deep `Background Primary` (`#313338` light theme, `#1e1f22` dark theme), with chat columns layered on slightly lighter or darker shades to denote channels, threads, and side panels. The signature **Blurple** (`#5865f2`) is reserved for the brand mark, primary CTAs, mentions, and the "you" affordance — used sparingly so it pops against the muted neutrals.
Typography is **gg sans** (Discord's custom Whitney-replacement) for prose and chrome, with rounded geometric shapes that feel approachable but still legible at the small sizes a chat client demands. Headings step up incrementally; chat rows are tight (4–8px between message groups) so hours of scrollback feel scannable.
The shape language is rounded but not balloon-soft: 8px radii on cards, 4px on inputs, full pills on status badges and tags. Servers are rounded-square avatars at 48px that morph to circles on hover — a tiny piece of motion that has become part of the brand's identity.
**Key Characteristics:**
- Dark-first surfaces: `#1e1f22` / `#2b2d31` / `#313338` (3-step depth)
- Blurple `#5865f2` as the only saturated accent in the chat surface
- gg sans (Whitney-style) for all text — friendly, geometric, neutral
- Rounded-square server avatars (16px radius) that snap to circles on hover
- Tight chat-row spacing, generous side-panel padding
- Status dots: green online, yellow idle, red dnd, gray offline
- Pixel-snapped 1px dividers in subtle off-white at low alpha
## 2. Color Palette & Roles
### Primary
- **Blurple** (`#5865f2`): Brand primary, primary CTA, mention highlight.
- **Blurple Hover** (`#4752c4`): Hover/active for blurple.
- **Blurple Soft** (`#7289da`): Legacy blurple, secondary accent in marketing.
### Surface (Dark Theme — default)
- **Background Tertiary** (`#1e1f22`): Server list rail, deepest background.
- **Background Secondary** (`#2b2d31`): Channel sidebar, settings sidebar.
- **Background Primary** (`#313338`): Chat surface, message column.
- **Background Floating** (`#111214`): Floating popovers, tooltips, autocomplete.
- **Background Modifier Hover** (`rgba(78, 80, 88, 0.3)`): Hover overlay on rows.
- **Background Modifier Selected** (`rgba(78, 80, 88, 0.6)`): Active row.
### Surface (Light Theme)
- **Light Bg Primary** (`#ffffff`): Chat surface in light theme.
- **Light Bg Secondary** (`#f2f3f5`): Sidebar in light theme.
- **Light Bg Tertiary** (`#e3e5e8`): Deepest light surface.
### Text
- **Header Primary** (`#f2f3f5`): Channel headers, modal titles in dark theme.
- **Header Secondary** (`#b5bac1`): Muted headers.
- **Text Normal** (`#dbdee1`): Body text in dark theme — slightly cooler than pure white.
- **Text Muted** (`#949ba4`): Timestamps, server names, secondary metadata.
- **Text Link** (`#00a8fc`): Hyperlinks in messages — sky blue, distinct from blurple.
- **Channels Default** (`#80848e`): Inactive channel name in sidebar.
### Status & Semantic
- **Status Online** (`#23a55a`): Online dot, success states.
- **Status Idle** (`#f0b232`): Idle dot, away.
- **Status DND** (`#f23f43`): Do-not-disturb, also serves as destructive red.
- **Status Streaming** (`#593695`): "Streaming" purple.
- **Status Offline** (`#80848e`): Offline gray.
- **Mention Highlight** (`rgba(88, 101, 242, 0.1)`): Soft blurple wash on @mention rows.
### Border & Divider
- **Background Modifier Accent** (`rgba(255, 255, 255, 0.06)`): Standard divider in dark.
- **Border Subtle** (`#3f4147`): Solid divider for cards.
## 3. Typography Rules
### Font Family
- **Body / UI / Headings**: `gg sans`, with fallback: `"Helvetica Neue", Helvetica, Arial, sans-serif`
- **Display (legacy / Whitney)**: `Whitney`, with fallback: `gg sans`
- **Code / Mono**: `"gg mono"`, with fallback: `Consolas, Andale Mono, Courier New, Courier, monospace`
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display Hero | gg sans | 56px (3.5rem) | 800 | 1.1 | -0.02em | Marketing hero |
| Page Heading | gg sans | 24px (1.5rem) | 700 | 1.25 | normal | Settings/profile titles |
| Channel Name | gg sans | 16px (1rem) | 600 | 1.25 | normal | `#general`, channel header |
| Message Body | gg sans | 16px (1rem) | 400 | 1.375 | normal | Standard chat text |
| Username | gg sans | 16px (1rem) | 500 | 1.25 | normal | Author of a message |
| Timestamp | gg sans | 12px (0.75rem) | 500 | 1.25 | normal | "Today at 4:32 PM" |
| Sidebar Channel | gg sans | 16px (1rem) | 500 | 1.25 | normal | Channel list rows |
| Server Name | gg sans | 16px (1rem) | 600 | 1.25 | normal | Server header |
| Caption / Meta | gg sans | 12px (0.75rem) | 400 | 1.3 | 0.02em | Status text, edited tag |
| Code Inline | gg mono | 0.875em | 400 | inherit | normal | Inline `code` |
| Code Block | gg mono | 14px (0.875rem) | 400 | 1.5 | normal | ```triple-fenced``` block |
### Principles
- **Friendly geometry**: gg sans replaces Whitney with rounded terminals on a/g/s — the brand wants warmth without breaking legibility.
- **Weight contrast over color contrast**: hierarchy comes from 400→500→600→700→800 weight steps; the surface stays neutral.
- **16px body**: chat messages do not shrink below 16px. Density comes from line-height (1.375), not font size.

# Design System Inspired by Duolingo
> Category: Productivity & SaaS
> Language-learning platform. Bright owl green, chunky shadows, gamified joy.
## 1. Visual Theme & Atmosphere
Duolingo is gamification rendered as visual language. The interface is unapologetically bright, with **owl green** (`#58cc02`) as the brand primary and a chunky 4px bottom-shadow on every interactive element that reads like a 3D button waiting to be pressed. The page is white (`#ffffff`) with thick 2–3px borders in a deep gray (`#e5e5e5`) and the entire system reads like an iOS app from 2015 reborn with better hierarchy.
Typography uses **Feather Bold** (a custom rounded sans) for chrome and **Mona Sans** (or Inter) for body. Display sizes are big and confident — Duolingo never whispers. Headings often carry the green underline-stroke or sit on a green pill, and the mascot Duo (a green owl) appears as an active illustration character, not a static logo.
Shape language is friendly: 16–20px radii on cards, 12px on buttons, 9999px on chips and progress bars. Iconography is filled, rounded, and color-coded by skill — every lesson surface has an instantly identifiable color pairing.
**Key Characteristics:**
- Owl green (`#58cc02`) as the dominant brand color, used in 30%+ of the surface
- Chunky 4px bottom-shadow on every button (the "tactile press" affordance)
- 2–3px solid borders, never hairlines
- Feather Bold (rounded display) + Mona Sans (body)
- Big confident type — display sizes start at 48px and climb
- Mascot-as-character: Duo the owl appears in onboarding, errors, streaks
- Streak orange (`#ff9600`) and gem pink (`#ce82ff`) as secondary brand colors
## 2. Color Palette & Roles
### Primary
- **Owl Green** (`#58cc02`): Brand primary, primary CTA, correct answer.
- **Owl Green Deep** (`#58a700`): Pressed/shadow color for green buttons.
- **Owl Green Light** (`#89e219`): Hover, soft fills.
- **Owl Green Pale** (`#dbf8c5`): Soft surface, success banner.
### Secondary Accents
- **Streak Orange** (`#ff9600`): Streak counter, fire icon, premium energy.
- **Streak Orange Deep** (`#cc7a00`): Pressed orange.
- **Gem Pink** (`#ce82ff`): Gem currency, Super Duolingo.
- **Eel Blue** (`#1cb0f6`): Hint button, info link.
- **Cardinal Red** (`#ff4b4b`): Wrong answer, life lost.
- **Bee Yellow** (`#ffc800`): Pro badge, achievement.
### Surface
- **Snow** (`#ffffff`): Primary background.
- **Eel** (`#f7f7f7`): Section break, secondary surface.
- **Swan** (`#e5e5e5`): Disabled background, inset block.
- **Wolf** (`#777777`): Dark divider, secondary text.
### Ink & Text
- **Eel Black** (`#3c3c3c`): Primary text.
- **Wolf** (`#777777`): Secondary text, captions.
- **Hare** (`#afafaf`): Disabled, placeholder.
### Border
- **Swan** (`#e5e5e5`): Standard 2px border.
- **Hare** (`#afafaf`): Emphasized border on hover.
## 3. Typography Rules
### Font Family
- **Display / UI / Headings**: `Feather Bold`, with fallback: `'DIN Round Pro', 'Helvetica Neue', sans-serif`
- **Body / Long-form**: `Mona Sans`, with fallback: `'Helvetica Neue', system-ui, sans-serif`
- **Code (rare, schools/admin)**: `JetBrains Mono`, with fallback: `ui-monospace, Menlo, monospace`
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display | Feather Bold | 56px (3.5rem) | 800 | 1.05 | -0.01em | Onboarding hero |
| H1 | Feather Bold | 32px (2rem) | 800 | 1.15 | -0.005em | Page title |
| H2 | Feather Bold | 24px (1.5rem) | 800 | 1.2 | normal | Section heading |
| H3 | Feather Bold | 18px (1.125rem) | 700 | 1.25 | normal | Card title, lesson row |
| Body Large | Mona Sans | 17px (1.0625rem) | 500 | 1.5 | normal | Lesson prompt, instruction |
| Body | Mona Sans | 15px (0.9375rem) | 400 | 1.5 | normal | Standard prose |
| Caption | Mona Sans | 13px (0.8125rem) | 600 | 1.4 | 0.01em | XP counter, metadata |
| Button | Feather Bold | 16px (1rem) | 800 | 1.2 | 0.02em | Standard button label |
| Streak | Feather Bold | 14px (0.875rem) | 800 | 1.2 | normal | Streak number, on flame |
### Principles
- **800 is default**: Feather Bold runs at 800 across headings and buttons. 700 feels weak in this system.
- **Big type**: heading sizes are 25–40% larger than typical product brands — confidence as identity.
- **Rounded letterforms**: every glyph has soft terminals; sharp serifs would break the friendliness contract.

# Design System Inspired by ElevenLabs
> Category: AI & LLM
> AI voice platform. Dark cinematic UI, audio-waveform aesthetics.
## 1. Visual Theme & Atmosphere
ElevenLabs' website is a study in restrained elegance — a near-white canvas (`#ffffff`, `#f5f5f5`) where typography and subtle shadows do all the heavy lifting. The design feels like a premium audio product brochure: clean, spacious, and confident enough to let the content speak (literally, given ElevenLabs makes voice AI). There's an almost Apple-like quality to the whitespace strategy, but warmer — the occasional warm stone tint (`#f5f2ef`, `#777169`) prevents the purity from feeling clinical.
The typography system is built on a fascinating duality: Waldenburg at weight 300 (light) for display headings creates ethereal, whisper-thin titles that feel like sound waves rendered in type — delicate, precise, and surprisingly impactful at large sizes. This light-weight display approach is the design's signature — where most sites use bold headings to grab attention, ElevenLabs uses lightness to create intrigue. Inter handles all body and UI text with workmanlike reliability, using slight positive letter-spacing (0.14px–0.18px) that gives body text an airy, well-spaced quality. WaldenburgFH appears as a bold uppercase variant for specific button labels.
What makes ElevenLabs distinctive is its multi-layered shadow system. Rather than simple box-shadows, elements use complex stacks: inset border-shadows (`rgba(0,0,0,0.075) 0px 0px 0px 0.5px inset`), outline shadows (`rgba(0,0,0,0.06) 0px 0px 0px 1px`), and soft elevation shadows (`rgba(0,0,0,0.04) 0px 4px 4px`) — all at remarkably low opacities. The result is a design where surfaces seem to barely exist, floating just above the page with the lightest possible touch. Pill-shaped buttons (9999px) with warm-tinted backgrounds (`rgba(245,242,239,0.8)`) and warm shadows (`rgba(78,50,23,0.04)`) add a tactile, physical quality.
**Key Characteristics:**
- Near-white canvas with warm undertones (`#f5f5f5`, `#f5f2ef`)
- Waldenburg weight 300 (light) for display — ethereal, whisper-thin headings
- Inter with positive letter-spacing (0.14–0.18px) for body — airy readability
- Multi-layered shadow stacks at sub-0.1 opacity — surfaces barely exist
- Pill buttons (9999px) with warm stone-tinted backgrounds
- WaldenburgFH bold uppercase for specific CTA labels
- Warm shadow tints: `rgba(78, 50, 23, 0.04)` — shadows have color, not just darkness
- Geist Mono / ui-monospace for code snippets
## 2. Color Palette & Roles
### Primary
- **Pure White** (`#ffffff`): Primary background, card surfaces, button backgrounds
- **Light Gray** (`#f5f5f5`): Secondary surface, subtle section differentiation
- **Warm Stone** (`#f5f2ef`): Button background (at 80% opacity) — the warm signature
- **Black** (`#000000`): Primary text, headings, dark buttons
### Neutral Scale
- **Dark Gray** (`#4e4e4e`): Secondary text, descriptions
- **Warm Gray** (`#777169`): Tertiary text, muted links, decorative underlines
- **Near White** (`#f6f6f6`): Alternate light surface
### Interactive
- **Grid Cyan** (`#7fffff`): `--grid-column-bg`, at 25% opacity — decorative grid overlay

- **Inset Dark** (`rgba(0,0,0,0.1) 0px 0px 0px 0.5px inset`): Stronger inset variant
- **Outline Ring** (`rgba(0,0,0,0.06) 0px 0px 0px 1px`): Shadow-as-border
- **Soft Elevation** (`rgba(0,0,0,0.04) 0px 4px 4px`): Gentle lift
- **Card Shadow** (`rgba(0,0,0,0.4) 0px 0px 1px, rgba(0,0,0,0.04) 0px 4px 4px`): Button/card elevation
- **Warm Shadow** (`rgba(78,50,23,0.04) 0px 6px 16px`): Warm-tinted button shadow
- **Edge Shadow** (`rgba(0,0,0,0.08) 0px 0px 0px 0.5px`): Subtle edge definition
- **Inset Ring** (`rgba(0,0,0,0.1) 0px 0px 0px 1px inset`): Strong inset border
## 3. Typography Rules
### Font Families
- **Display**: `Waldenburg`, fallback: `Waldenburg Fallback`
- **Display Bold**: `WaldenburgFH`, fallback: `WaldenburgFH Fallback`
- **Body / UI**: `Inter`, fallback: `Inter Fallback`
- **Monospace**: `Geist Mono` or `ui-monospace, SFMono-Regular, Menlo, Monaco, Consolas`
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display Hero | Waldenburg | 48px (3.00rem) | 300 | 1.08 (tight) | -0.96px | Whisper-thin, ethereal |
| Section Heading | Waldenburg | 36px (2.25rem) | 300 | 1.17 (tight) | normal | Light display |
| Card Heading | Waldenburg | 32px (2.00rem) | 300 | 1.13 (tight) | normal | Light card titles |
| Body Large | Inter | 20px (1.25rem) | 400 | 1.35 | normal | Introductions |
| Body | Inter | 18px (1.13rem) | 400 | 1.44–1.60 | 0.18px | Standard reading text |
| Body Standard | Inter | 16px (1.00rem) | 400 | 1.50 | 0.16px | UI text |
| Body Medium | Inter | 16px (1.00rem) | 500 | 1.50 | 0.16px | Emphasized body |
| Nav / UI | Inter | 15px (0.94rem) | 500 | 1.33–1.47 | 0.15px | Navigation links |
| Button | Inter | 15px (0.94rem) | 500 | 1.47 | normal | Button labels |
| Button Uppercase | WaldenburgFH | 14px (0.88rem) | 700 | 1.10 (tight) | 0.7px | `text-transform: uppercase` |
| Caption | Inter | 14px (0.88rem) | 400–500 | 1.43–1.50 | 0.14px | Metadata |
| Small | Inter | 13px (0.81rem) | 500 | 1.38 | normal | Tags, badges |
| Code | Geist Mono | 13px (0.81rem) | 400 | 1.85 (relaxed) | normal | Code blocks |
| Micro | Inter | 12px (0.75rem) | 500 | 1.33 | normal | Tiny labels |
| Tiny | Inter | 10px (0.63rem) | 400 | 1.60 (relaxed) | normal | Fine print |
### Principles
- **Light as the hero weight**: Waldenburg at 300 is the defining typographic choice. Where other design systems use bold for impact, ElevenLabs uses lightness — thin strokes that feel like audio waveforms, creating intrigue through restraint.
- **Positive letter-spacing on body**: Inter uses +0.14px to +0.18px tracking across body text, creating an airy, well-spaced reading rhythm that contrasts with the tight display tracking (-0.96px).
- **WaldenburgFH for emphasis**: A bold (700) uppercase variant of Waldenburg appears only in specific CTA button labels with 0.7px letter-spacing — the one place where the type system gets loud.
- **Monospace as ambient**: Geist Mono at relaxed line-height (1.85) for code blocks feels unhurried and readable.

### Inputs & Forms
- Textarea: padding 12px 20px, transparent text at default
- Select: white background, standard styling
- Radio: standard with tw-ring focus
- Focus: `var(--tw-ring-offset-shadow)` ring system
### Navigation
- Clean white sticky header
- Inter 15px weight 500 for nav links
- Pill CTAs right-aligned (black primary, white secondary)
- Mobile: hamburger collapse at 1024px
### Image Treatment
- Product screenshots and audio waveform visualizations
- Warm gradient backgrounds in feature sections
- 20px–24px radius on image containers
- Full-width sections alternating white and light gray
### Distinctive Components
**Audio Waveform Sections**
- Colorful gradient backgrounds showcasing voice AI capabilities
- Warm amber, blue, and green gradients behind product demos
- Screenshots of the ElevenLabs product interface
**Warm Stone CTA Block**
- `rgba(245,242,239,0.8)` background with warm shadow
- Asymmetric padding (more right padding)
- Creates a physical, tactile quality unique to ElevenLabs
## 5. Layout Principles
### Spacing System
- Base unit: 8px
- Scale: 1px, 3px, 4px, 8px, 9px, 10px, 11px, 12px, 16px, 18px, 20px, 24px, 28px, 32px, 40px
### Grid & Container
- Centered content with generous max-width
- Single-column hero, expanding to feature grids
- Full-width gradient sections for product showcases
- White card grids on light gray backgrounds
### Whitespace Philosophy
- **Apple-like generosity**: Massive vertical spacing between sections creates a premium, unhurried pace. Each section is an exhibit.
- **Warm emptiness**: The whitespace isn't cold — the warm stone undertones and warm shadows give empty space a tactile, physical quality.
- **Typography-led rhythm**: The light-weight Waldenburg headings create visual "whispers" that draw the eye through vast white space.
### Border Radius Scale
- Minimal (2px): Small links, inline elements
- Subtle (4px): Nav items, tab panels, tags
- Standard (8px): Small containers
- Comfortable (10px–12px): Medium cards, dropdowns
- Card (16px): Standard cards, articles
- Large (18px–20px): Featured cards, code panels
- Section (24px): Large panels, section containers
- Warm Button (30px): Warm stone CTA
- Pill (9999px): Primary buttons, navigation pills
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Page background, text blocks |
| Inset Edge (Level 0.5) | `rgba(0,0,0,0.075) 0px 0px 0px 0.5px inset, #fff 0px 0px 0px 0px inset` | Internal border definition |
| Outline Ring (Level 1) | `rgba(0,0,0,0.06) 0px 0px 0px 1px` + `rgba(0,0,0,0.04) 0px 1px 2px` + `rgba(0,0,0,0.04) 0px 2px 4px` | Shadow-as-border for cards |
| Card (Level 2) | `rgba(0,0,0,0.4) 0px 0px 1px, rgba(0,0,0,0.04) 0px 4px 4px` | Button elevation, prominent cards |
| Warm Lift (Level 3) | `rgba(78,50,23,0.04) 0px 6px 16px` | Featured CTAs — warm-tinted |
| Focus (Accessibility) | `var(--tw-ring-offset-shadow)` blue ring | Keyboard focus |
**Shadow Philosophy**: ElevenLabs uses the most refined shadow system of any design system analyzed. Every shadow is at sub-0.1 opacity, many include both outward cast AND inward inset components, and the warm CTA shadows use an actual warm color (`rgba(78,50,23,...)`) rather than neutral black. The inset half-pixel borders (`0px 0px 0px 0.5px inset`) create edges so subtle they're felt rather than seen — surfaces define themselves through the lightest possible touch.
## 7. Do's and Don'ts
### Do
- Use Waldenburg weight 300 for all display headings — the lightness IS the brand
- Apply multi-layer shadows (inset + outline + elevation) at sub-0.1 opacity
- Use warm stone tints (`#f5f2ef`, `rgba(245,242,239,0.8)`) for featured elements
- Apply positive letter-spacing (+0.14px to +0.18px) on Inter body text
- Use 9999px radius for primary buttons — pill shape is standard
- Use warm-tinted shadows (`rgba(78,50,23,0.04)`) on featured CTAs
- Keep the page predominantly white with subtle gray section differentiation
- Use WaldenburgFH bold uppercase ONLY for specific CTA button labels
### Don't
- Don't use bold (700) Waldenburg for headings — weight 300 is non-negotiable
- Don't use heavy shadows (>0.1 opacity) — the ethereal quality requires whisper-level depth
- Don't use cool gray borders — the system is warm-tinted throughout
- Don't skip the inset shadow component — half-pixel inset borders define edges
- Don't apply negative letter-spacing to body text — Inter uses positive tracking
- Don't use sharp corners (<8px) on cards — the generous radius is structural
- Don't introduce brand colors — the palette is intentionally achromatic with warm undertones
- Don't make buttons opaque and heavy — the warm translucent stone treatment is the signature
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | <1024px | Single column, hamburger nav, stacked sections |
| Desktop | >1024px | Full layout, horizontal nav, multi-column grids |
### Touch Targets
- Pill buttons with generous padding (12px–20px)
- Navigation links at 15px with adequate spacing
- Select dropdowns maintain comfortable sizing
### Collapsing Strategy
- Navigation: horizontal → hamburger at 1024px
- Feature grids: multi-column → stacked
- Hero: maintains centered layout, font scales proportionally
- Gradient sections: full-width maintained, content stacks
- Spacing compresses proportionally
### Image Behavior
- Product screenshots scale responsively
- Gradient backgrounds simplify on mobile
- Audio waveform previews maintain aspect ratio
- Rounded corners maintained across breakpoints
## 9. Agent Prompt Guide
### Quick Color Reference
- Background: Pure White (`#ffffff`) or Light Gray (`#f5f5f5`)
- Text: Black (`#000000`)
- Secondary text: Dark Gray (`#4e4e4e`)
- Muted text: Warm Gray (`#777169`)
- Warm surface: Warm Stone (`rgba(245, 242, 239, 0.8)`)
- Border: `#e5e5e5` or `rgba(0,0,0,0.05)`

### Iteration Guide
1. Start with white — the warm undertone comes from shadows and stone surfaces, not backgrounds
2. Waldenburg 300 for headings — never bold, the lightness is the identity
3. Multi-layer shadows: always include inset + outline + elevation at sub-0.1 opacity
4. Positive letter-spacing on Inter body (+0.14px to +0.18px) — the airy reading quality
5. Warm stone CTA is the signature — `rgba(245,242,239,0.8)` with `rgba(78,50,23,0.04)` shadow
6. Pill (9999px) for buttons, generous radius (16px–24px) for cards

# Design System Inspired by Expo
> Category: Developer Tools
> React Native platform. Dark theme, tight letter-spacing, code-centric.
## 1. Visual Theme & Atmosphere
Expo's interface is a luminous, confidence-radiating developer platform built on the premise that tools for building apps should feel as polished as the apps themselves. The entire experience lives on a bright, airy canvas — a cool-tinted off-white (`#f0f0f3`) that gives the page a subtle technological coolness without the starkness of pure white. This is a site that breathes: enormous vertical spacing between sections creates a gallery-like pace where each feature gets its own "room."
The design language is decisively monochromatic — pure black (`#000000`) headlines against the lightest possible backgrounds, with a spectrum of cool blue-grays (`#60646c`, `#b0b4ba`, `#555860`) handling all secondary communication. Color is almost entirely absent from the interface itself; when it appears, it's reserved for product screenshots, app icons, and the React universe illustration — making the actual content burst with life against the neutral canvas.
What makes Expo distinctive is its pill-shaped geometry. Buttons, tabs, video containers, and even images use generously rounded or fully pill-shaped corners (24px–9999px), creating an organic, approachable feel that contradicts the typical sharp-edged developer tool aesthetic. Combined with tight letter-spacing on massive headlines (-1.6px to -3px at 64px), the result is a design that's simultaneously premium and friendly — like an Apple product page reimagined for developers.
**Key Characteristics:**
- Luminous cool-white canvas (`#f0f0f3`) with gallery-like vertical spacing
- Strictly monochromatic: pure black headlines, cool blue-gray body text, no decorative color
- Pill-shaped geometry everywhere — buttons, tabs, containers, images (24px–9999px radius)
- Massive display headlines (64px) with extreme negative letter-spacing (-1.6px to -3px)
- Inter as the sole typeface, used at weights 400–900 for full expressive range
- Whisper-soft shadows that barely lift elements from the surface
- Product screenshots as the only source of color in the interface
## 2. Color Palette & Roles
### Primary
- **Expo Black** (`#000000`): The absolute anchor — used for primary headlines, CTA buttons, and the brand identity. Pure black on cool white creates maximum contrast without feeling aggressive.
- **Near Black** (`#1c2024`): The primary text color for body content — a barely perceptible blue-black that's softer than pure #000 for extended reading.
### Secondary & Accent
- **Link Cobalt** (`#0d74ce`): The standard link color — a trustworthy, saturated blue that signals interactivity without competing with the monochrome hierarchy.
- **Legal Blue** (`#476cff`): A brighter, more saturated blue for legal/footer links — slightly more attention-grabbing than Link Cobalt.
- **Widget Sky** (`#47c2ff`): A light, friendly cyan-blue for widget branding elements — the brightest accent in the system.
- **Preview Purple** (`#8145b5`): A rich violet used for "preview" or beta feature indicators — creating clear visual distinction from standard content.
### Surface & Background
- **Cloud Gray** (`#f0f0f3`): The primary page background — a cool off-white with the faintest blue-violet tint. Not warm, not sterile — precisely technological.
- **Pure White** (`#ffffff`): Card surfaces, button backgrounds, and elevated content containers. Creates a clear "lifted" distinction from Cloud Gray.
- **Widget Dark** (`#1a1a1a`): Dark surface for dark-theme widgets and overlay elements.
- **Banner Dark** (`#171717`): The darkest surface variant, used for promotional banners and high-contrast containers.
### Neutrals & Text
- **Slate Gray** (`#60646c`): The workhorse secondary text color (305 instances). A cool blue-gray that's authoritative without being heavy.
- **Mid Slate** (`#555860`): Slightly darker than Slate, used for emphasized secondary text.
- **Silver** (`#b0b4ba`): Tertiary text, placeholders, and de-emphasized metadata. Comfortably readable but clearly receded.
- **Pewter** (`#999999`): Accordion icons and deeply de-emphasized UI elements in dark contexts.
- **Light Silver** (`#cccccc`): Arrow icons and decorative elements in dark contexts.
- **Dark Slate** (`#363a3f`): Borders on dark surfaces, switch tracks, and emphasized containment.
- **Charcoal** (`#333333`): Dark mode switch backgrounds and deep secondary surfaces.
### Semantic & Accent
- **Warning Amber** (`#ab6400`): A warm, deep amber for warning states — deliberately not bright yellow, conveying seriousness.
- **Destructive Rose** (`#eb8e90`): A soft pink-coral for disabled destructive actions — gentler than typical red, reducing alarm fatigue.
- **Border Lavender** (`#e0e1e6`): Standard card/container borders — a cool lavender-gray that's visible without being heavy.
- **Input Border** (`#d9d9e0`): Button and form element borders — slightly warmer/darker than card borders for interactive elements.
- **Dark Focus Ring** (`#2547d0`): Deep blue for keyboard focus indicators in dark theme contexts.
### Gradient System
- The design is notably **gradient-free** in the interface layer. Visual richness comes from product screenshots, the React universe illustration, and careful shadow layering rather than color gradients. This absence IS the design decision — gradients would undermine the clinical precision.
## 3. Typography Rules
### Font Family
- **Primary**: `Inter`, with fallbacks: `-apple-system, system-ui`
- **Monospace**: `JetBrains Mono`, with fallback: `ui-monospace`
- **System Fallback**: `system-ui, Segoe UI, Roboto, Helvetica, Arial, Apple Color Emoji, Segoe UI Emoji`
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display / Hero | Inter | 64px (4rem) | 700–900 | 1.10 (tight) | -1.6px to -3px | Maximum impact, extreme tracking |
| Section Heading | Inter | 48px (3rem) | 600 | 1.10 (tight) | -2px | Feature section anchors |
| Sub-heading | Inter | 20px (1.25rem) | 600 | 1.20 (tight) | -0.25px | Card titles, feature names |
| Body Large | Inter | 18px (1.13rem) | 400–500 | 1.40 | normal | Intro paragraphs, section descriptions |
| Body / Button | Inter | 16px (1rem) | 400–700 | 1.25–1.40 | normal | Standard text, nav links, buttons |
| Caption / Label | Inter | 14px (0.88rem) | 400–600 | 1.00–1.40 | normal | Descriptions, metadata, badge text |
| Tag / Small | Inter | 12px (0.75rem) | 500 | 1.00–1.60 | normal | Smallest sans-serif text, badges |
| Code Body | JetBrains Mono | 16px (1rem) | 400–600 | 1.40 | normal | Inline code, terminal commands |
| Code Caption | JetBrains Mono | 14px (0.88rem) | 400–600 | 1.40 | normal | Code snippets, technical labels |
| Code Small | JetBrains Mono | 12px (0.75rem) | 400 | 1.60 | normal | Uppercase tech tags |
### Principles
- **One typeface, full expression**: Inter is the only sans-serif, used from weight 400 (regular) through 900 (black). This gives the design a unified voice while still achieving dramatic contrast between whisper-light body text and thundering display headlines.
- **Extreme negative tracking at scale**: Headlines at 64px use -1.6px to -3px letter-spacing, creating ultra-dense text blocks that feel like logotypes. This aggressive compression is the signature typographic move.
- **Weight as hierarchy**: 700–900 for display, 600 for headings, 500 for emphasis, 400 for body. The jumps are decisive — no ambiguous in-between weights.
- **Consistent 1.40 body line-height**: Nearly all body and UI text shares 1.40 line-height, creating a rhythmic vertical consistency.
## 4. Component Stylings
### Buttons
**Primary (White on border)**
- Background: Pure White (`#ffffff`)
- Text: Near Black (`#1c2024`)
- Padding: 0px 12px (compact, content-driven height)
- Border: thin solid Input Border (`1px solid #d9d9e0`)
- Radius: subtly rounded (6px)
- Shadow: subtle combined shadow on hover
- The understated default — clean, professional, unheroic
**Primary Pill**
- Same as Primary but with pill-shaped radius (9999px)
- Used for hero CTAs and high-emphasis actions
- The extra roundness signals "start here"
**Dark Primary**
- Background: Expo Black (`#000000`)
- Text: Pure White (`#ffffff`)
- Pill-shaped (9999px) or generously rounded (32–36px)
- No border (black IS the border)
- The maximum-emphasis CTA — reserved for primary conversion actions
### Cards & Containers
- Background: Pure White (`#ffffff`) — clearly lifted from Cloud Gray page
- Border: thin solid Border Lavender (`1px solid #e0e1e6`) for standard cards
- Radius: comfortably rounded (8px) for standard cards; generously rounded (16–24px) for featured containers
- Shadow Level 1: Whisper (`rgba(0,0,0,0.08) 0px 3px 6px, rgba(0,0,0,0.07) 0px 2px 4px`) — barely perceptible lift
- Shadow Level 2: Standard (`rgba(0,0,0,0.1) 0px 10px 20px, rgba(0,0,0,0.05) 0px 3px 6px`) — clear floating elevation
- Hover: likely subtle shadow deepening or background shift
### Inputs & Forms
- Background: Pure White (`#ffffff`)
- Text: Near Black (`#1c2024`)
- Border: thin solid Input Border (`1px solid #d9d9e0`)
- Padding: 0px 12px (inline with button sizing)
- Radius: subtly rounded (6px)
- Focus: blue ring shadow via CSS custom property
### Navigation
- Sticky top nav on transparent/blurred background
- Logo: Expo wordmark in black
- Links: Near Black (`#1c2024`) or Slate Gray (`#60646c`) at 14–16px Inter weight 500
- CTA: Black pill button ("Sign Up") on the right
- GitHub star badge as social proof
- Status indicator ("All Systems Operational") with green dot
### Image Treatment
- Product screenshots and device mockups are the visual heroes
- Generously rounded corners (24px) on video and image containers
- Screenshots shown in realistic device frames
- Dark UI screenshots provide contrast against the light canvas
- Full-bleed within rounded containers
### Distinctive Components
**Universe React Logo**
- Animated/illustrated React logo as the visual centerpiece
- Connects Expo's identity to the React ecosystem
- The only illustrative element on an otherwise photographic page
**Device Preview Grid**
- Multiple device types (phone, tablet, web) shown simultaneously
- Demonstrates cross-platform capability visually
- Each device uses realistic device chrome
**Status Badge**
- "All Systems Operational" pill in the nav
- Green dot + text — compact trust signal
- Pill-shaped (36px radius)
## 5. Layout Principles
### Spacing System
- Base unit: 8px
- Scale: 1px, 2px, 4px, 8px, 12px, 16px, 24px, 32px, 40px, 48px, 64px, 80px, 96px, 144px
- Button padding: 0px 12px (unusually compact — height driven by line-height)
- Card internal padding: approximately 24–32px
- Section vertical spacing: enormous (estimated 96–144px between major sections)
- Component gap: 16–24px between sibling elements
### Grid & Container
- Max container width: approximately 1200–1400px, centered
- Hero: centered single-column with massive breathing room
- Feature sections: alternating layouts (image left/right, full-width showcases)
- Card grids: 2–3 column for feature highlights
- Full-width sections with contained inner content
### Whitespace Philosophy
- **Gallery-like pacing**: Each section feels like its own exhibit, surrounded by vast empty space. This creates a premium, unhurried browsing experience.
- **Breathing room is the design**: The generous whitespace IS the primary design element — it communicates confidence, quality, and that each feature deserves individual attention.
- **Content islands**: Sections float as isolated "islands" in the white space, connected by scrolling rather than visual continuation.
### Border Radius Scale
- Nearly squared (4px): Small inline elements, tags
- Subtly rounded (6px): Buttons, form inputs, combo boxes — the functional interactive radius
- Comfortably rounded (8px): Standard content cards, containers
- Generously rounded (16px): Feature tabs, content panels
- Very rounded (24px): Buttons, video/image containers, tabpanels — the signature softness
- Highly rounded (32–36px): Hero CTAs, status badges, nav buttons
- Pill-shaped (9999px): Primary action buttons, tags, avatars — maximum friendliness
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Cloud Gray page background, inline text |
| Surface (Level 1) | White bg, no shadow | Standard white cards on Cloud Gray |
| Whisper (Level 2) | `rgba(0,0,0,0.08) 0px 3px 6px` + `rgba(0,0,0,0.07) 0px 2px 4px` | Subtle card lift, hover states |
| Elevated (Level 3) | `rgba(0,0,0,0.1) 0px 10px 20px` + `rgba(0,0,0,0.05) 0px 3px 6px` | Feature showcases, product screenshots |
| Modal (Level 4) | Dark overlay (`--dialog-overlay-background-color`) + heavy shadow | Dialogs, overlays |
**Shadow Philosophy**: Expo uses shadows as gentle whispers rather than architectural statements. The primary depth mechanism is **background color contrast** — white cards floating on Cloud Gray — rather than shadow casting. When shadows appear, they're soft, diffused, and directional (downward), creating the feeling of paper hovering millimeters above a desk.
## 7. Do's and Don'ts
### Do
- Use Cloud Gray (`#f0f0f3`) as the page background and Pure White (`#ffffff`) for elevated cards — the two-tone light system is essential
- Keep display headlines at extreme negative letter-spacing (-1.6px to -3px at 64px) for the signature compressed look
- Use pill-shaped (9999px) radius for primary CTA buttons — the organic shape is core to the identity
- Reserve black (`#000000`) for headlines and primary CTAs — it carries maximum authority on the light canvas
- Use Slate Gray (`#60646c`) for secondary text — it's the precise balance between readable and receded
- Maintain enormous vertical spacing between sections (96px+) — the gallery pacing defines the premium feel
- Use product screenshots as the primary visual content — the interface stays monochrome, the products bring color
- Apply Inter at the full weight range (400–900) — weight contrast IS the hierarchy
### Don't
- Don't introduce decorative colors into the interface chrome — the monochromatic palette is intentional
- Don't use sharp corners (border-radius < 6px) on interactive elements — the pill/rounded geometry is the signature
- Don't reduce section spacing below 64px — the breathing room is the design
- Don't use heavy drop shadows — depth comes from background contrast and whisper-soft shadows
- Don't mix in additional typefaces — Inter handles everything from display to caption
- Don't use letter-spacing wider than -0.25px on body text — extreme tracking is reserved for display only
- Don't use borders heavier than 2px — containment is subtle, achieved through background color and gentle borders
- Don't add gradients to the interface — visual richness comes from content, not decoration
- Don't use saturated colors outside of semantic contexts — the palette is strictly grayscale + functional blue
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | <640px | Single column, hamburger nav, stacked cards, hero text scales to ~36px |
| Tablet | 640–1024px | 2-column grids, condensed nav, medium hero text |
| Desktop | >1024px | Full multi-column layout, expanded nav, massive hero (64px) |
*Only one explicit breakpoint detected (640px), suggesting a fluid, container-query or min()/clamp()-based responsive system rather than fixed breakpoint snapping.*
### Touch Targets
- Buttons use generous radius (24–36px) creating large, finger-friendly surfaces
- Navigation links spaced with adequate gap
- Status badge sized for touch (36px radius)
- Minimum recommended: 44x44px
### Collapsing Strategy
- **Navigation**: Full horizontal nav with CTA collapses to hamburger on mobile
- **Feature sections**: Multi-column → stacked single column
- **Hero text**: 64px → ~36px progressive scaling
- **Device previews**: Grid → stacked/carousel
- **Cards**: Side-by-side → vertical stacking
- **Spacing**: Reduces proportionally but maintains generous rhythm
### Image Behavior
- Product screenshots scale proportionally
- Device mockups may simplify or show fewer devices on mobile
- Rounded corners maintained at all sizes
- Lazy loading for below-fold content
## 9. Agent Prompt Guide
### Quick Color Reference
- Primary CTA / Headlines: "Expo Black (#000000)"
- Page Background: "Cloud Gray (#f0f0f3)"
- Card Surface: "Pure White (#ffffff)"
- Body Text: "Near Black (#1c2024)"
- Secondary Text: "Slate Gray (#60646c)"
- Borders: "Border Lavender (#e0e1e6)"
- Links: "Link Cobalt (#0d74ce)"
- Tertiary Text: "Silver (#b0b4ba)"
### Example Component Prompts
- "Create a hero section on Cloud Gray (#f0f0f3) with a massive headline at 64px Inter weight 700, line-height 1.10, letter-spacing -3px. Text in Expo Black (#000000). Below, add a subtitle in Slate Gray (#60646c) at 18px. Place a black pill-shaped CTA button (9999px radius) beneath."
- "Design a feature card on Pure White (#ffffff) with a 1px solid Border Lavender (#e0e1e6) border and comfortably rounded corners (8px). Title in Near Black (#1c2024) at 20px Inter weight 600, description in Slate Gray (#60646c) at 16px. Add a whisper shadow (rgba(0,0,0,0.08) 0px 3px 6px)."
- "Build a navigation bar with Expo logo on the left, text links in Near Black (#1c2024) at 14px Inter weight 500, and a black pill CTA button on the right. Background: transparent with blur backdrop. Bottom border: 1px solid Border Lavender (#e0e1e6)."
- "Create a code block using JetBrains Mono at 14px on a Pure White surface with Border Lavender border and 8px radius. Code in Near Black, keywords in Link Cobalt (#0d74ce)."
- "Design a status badge pill (9999px radius) with a green dot and 'All Systems Operational' text in Inter 12px weight 500. Background: Pure White, border: 1px solid Input Border (#d9d9e0)."
### Iteration Guide
1. Focus on ONE component at a time
2. Reference specific color names and hex codes — "use Slate Gray (#60646c)" not "make it gray"
3. Use radius values deliberately — 6px for buttons, 8px for cards, 24px for images, 9999px for pills
4. Describe the "feel" alongside measurements — "enormous breathing room with 96px section spacing"
5. Always specify Inter and the exact weight — weight contrast IS the hierarchy
6. For shadows, specify "whisper shadow" or "standard elevation" from the elevation table
7. Keep the interface monochrome — let product content be the color

# Design System Inspired by Ferrari
> Category: Automotive
> Luxury automotive. Chiaroscuro editorial, Ferrari Red accents, cinematic black.
## 1. Visual Theme & Atmosphere
Ferrari's website is a digital editorial — a curated magazine where the Prancing Horse brand is presented with the gravitas of an art institution and the precision of Italian coachwork. The page opens onto an expanse of absolute black, broken only by the iconic Prancing Horse emblem floating alone in its own atmosphere. Below, the content unfolds in dramatic alternations between inky-dark cinematic sections and crisp white editorial panels. This chiaroscuro rhythm — darkness yielding to light, machinery yielding to human story — feels more like paging through a Ferrari yearbook than scrolling a commercial website. Every section is a curated vignette: a concept car dissolving from shadow, two F1 drivers posed with sculptural stillness, a lineup of production models arranged in a jewel-toned parade.
The color language is monastically restrained for a brand built on speed and emotion. Ferrari Red (`#DA291C`) appears with almost surgical sparseness — reserved for the Subscribe CTA and accent moments that need to command immediate attention. The vast majority of the interface lives in black, white, and a carefully calibrated gray scale (from `#303030` dark surfaces through `#8F8F8F` mid-tones to `#D2D2D2` light borders). Two yellows — Racing Yellow (`#FFF200`) and the deeper Modena Yellow (`#F6E500`) — exist in the token system as heritage accents for special contexts, honoring Ferrari's racing provenance. The restraint means that when red does appear, it carries the weight of the entire brand.
Typography relies on FerrariSans — a proprietary sans-serif family with medium-weight headings (500–700) and compact proportions. Display text runs at 24–26px for section titles, while the UI chrome lives at 12–16px in weights ranging from regular to bold. A secondary "Body-Font" custom typeface handles captions and utility text, rendered in uppercase with wide letter-spacing (1px) to create a label-like editorial quality. This two-font system — FerrariSans for narrative authority, Body-Font for structural annotation — gives the site a print-magazine hierarchy. No text decoration is gratuitous. Letter-spacing is tight for headlines and deliberately expanded for labels, creating a visual rhythm that alternates between urgency and composure.
**Key Characteristics:**
- Chiaroscuro layout alternating between deep black sections and clean white editorial panels
- Ferrari Red (`#DA291C`) used with extreme sparseness — accent, not atmosphere
- Prancing Horse emblem as isolated hero element on a void-black field
- FerrariSans proprietary typeface with compact proportions and medium weights
- Photo-journalism imagery: concept renders, driver portraits, lineup parades — each section is a story
- Uppercase Body-Font labels with wide letter-spacing (1px) for editorial annotation
- Nearly zero border-radius (2px default) reflecting precision engineering aesthetics
- Dual-framework architecture (PrimeReact + Element Plus) powering 32+ interactive components
- Carousel-driven hero with editorial slides and arrow/dot navigation
## 2. Color Palette & Roles
### Primary
- **Ferrari Red** (`#DA291C`): The iconic Rosso Corsa — primary accent and CTA color. Used for the Subscribe button, key action triggers, and brand moments where maximum visual authority is needed. The single most important color in the system (--f-color-accent-100)
- **Pure White** (`#FFFFFF`): Primary surface for editorial content panels, navigation text on dark backgrounds, and button fills. The canvas that provides breathing room between dark cinematic sections (--f-color-ui-0)
### Secondary & Accent
- **Dark Red** (`#B01E0A`): Deeper variant of Ferrari Red for hover/pressed states and high-contrast contexts — adds dimensionality to the brand color without introducing a new hue (--f-color-accent-90)
- **Deep Red** (`#9D2211`): The most saturated dark red — used for active states and extra emphasis where even Dark Red needs more weight (--f-color-accent-80)
- **Racing Yellow** (`#FFF200`): Heritage accent from Ferrari's racing livery — reserved for special highlights and motorsport-related contexts (--f-color-yellow-hypersail)
- **Modena Yellow** (`#F6E500`): Slightly warmer and more golden than Racing Yellow — used for secondary heritage accents and category markers (--f-color-yellow)
### Surface & Background
- **Absolute Black** (`#000000`): Hero sections, cinematic backgrounds, and the dominant dark surface — the void that makes imagery and the Prancing Horse emblem float
- **Dark Surface** (`#303030`): Secondary dark surface for footer regions, newsletter sections, and layered dark panels — slightly lifted from pure black for depth differentiation (--f-color-ui-90)
- **Light Gray Surface** (`#D2D2D2`): Subtle alternate surface for dividers and border treatments on white panels (--f-color-ui-20)
- **Overlay Dark** (`hsla(0, 0%, 7%, 0.8)`): Semi-transparent near-black for modal overlays and image caption backgrounds (--f-color-overlay-darker)
### Neutrals & Text
- **Near Black** (`#181818`): Primary body text color on light surfaces — slightly softened from absolute black for better readability (link default color)
- **Dark Gray** (`#666666`): Secondary text and subdued UI labels — used where text needs to recede from the primary hierarchy (--f-color-black-60)
- **Mid Gray** (`#8F8F8F`): Tertiary text for metadata, timestamps, and supportive content (--f-color-black-50)
- **Silver Gray** (`#969696`): Placeholder text and disabled state indicators (--f-color-black-55)
### Semantic & Accent
- **Warning Red** (`#F13A2C`): Accessible warning state — brighter and more orange-shifted than Ferrari Red to differentiate semantic alerts from brand expression (--f-color-accessible-warning)
- **Success Green** (`#03904A`): Confirmation and positive status indicators (--f-color-accessible-success)
- **Info Blue** (`#4C98B9`): Informational callouts, tooltips, and neutral status messaging (--f-color-accessible-info)
- **Link Hover Blue** (`#3860BE`): Interactive hover state for text links — a dignified navy-blue that signals interactivity without competing with Ferrari Red
### Gradient System
- No explicit gradients in the token system
- Depth is achieved through photography and the binary contrast between black and white surfaces
- The overlay darker color (`hsla(0, 0%, 7%, 0.8)`) creates depth through transparency layering over imagery
- Occasional photographic gradients (light falloff in studio shots) provide atmospheric depth within image content
## 3. Typography Rules
### Font Family
- **FerrariSans**: Primary typeface for headings, navigation, buttons, and editorial content. A proprietary sans-serif with medium weight as the default (500), compact x-height, and precise letter-spacing control. Fallbacks: Arial, Helvetica, sans-serif
- **Body-Font**: Secondary typeface for captions, labels, and utility text. Frequently rendered in uppercase with expanded letter-spacing (1px) for an editorial label aesthetic. Used for category tags and small annotation text
- **Arial / Helvetica**: System fallback fonts used in cookie consent modals, form elements, and third-party component frameworks
### Hierarchy
| Role | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|--------|-------------|----------------|-------|
| Section Title | 26px (1.63rem) | 500 | 1.20 | normal | FerrariSans, primary editorial headings on white backgrounds |
| Card Heading | 24px (1.50rem) | 400 | normal | normal | FerrariSans, content card titles |
| Subheading | 18px (1.13rem) | 700 | 1.20 (tight) | normal | FerrariSans, bold subsection labels |
| UI Heading | 16px (1.00rem) | 500 | 1.40 | 0.08px | FerrariSans, component headings and nav items |
| Body Bold | 16px (1.00rem) | 700 | 1.30 (tight) | normal | FerrariSans, emphasized inline text |
| Button Label | 16px (1.00rem) | 400 | normal | 1.28px | FerrariSans, primary button text with wide tracking |
| Small Button | 14.4px (0.90rem) | 700 | 1.00 (tight) | normal | FerrariSans, compact action buttons |
| Nav Link | 13px (0.81rem) | 600 | 1.20 (tight) | 0.13px | FerrariSans, navigation and footer links |
| Caption | 13px (0.81rem) | 400 | 1.50 | 0.195px | FerrariSans/Body-Font, metadata and descriptions |
| Micro Button | 12px (0.75rem) | 700 | 1.00 (tight) | 0.96px | FerrariSans, small CTA with wide tracking |
| Label Upper | 12px (0.75rem) | 400 | 1.27 (tight) | 1px | Body-Font, uppercase labels and category tags |
| Micro Label | 11px (0.69rem) | 400 | 1.27 (tight) | 1px | Body-Font, uppercase smallest annotation text |
| Cookie Text | 45px (2.81rem) | 400 | 1.50 | 0.195px | Arial, consent dialog oversized button text |
### Principles
- **Proprietary identity**: FerrariSans is exclusive to Ferrari — it cannot be substituted without losing brand recognition. The font's compact proportions and medium weight default (500) convey engineering precision
- **Two-register system**: FerrariSans handles narrative voice (headings, content, buttons) while Body-Font handles structural annotation (labels, tags, micro-captions) — this mirrors print magazine conventions of editorial text vs. technical labels
- **Uppercase as emphasis tool**: Body-Font captions use `text-transform: uppercase` with expanded letter-spacing (1px) to create a visually distinct label layer that reads as "informational overlay" rather than primary content
- **Compact line-heights**: Headlines use tight line-heights (1.00–1.30) creating dense, impactful text blocks, while body text opens to 1.50 for comfortable reading — the contrast between compressed headers and relaxed body text creates visual tension
- **Weight range 400–700**: Four weights active in the system (400, 500, 600, 700) — significantly more range than Tesla but still controlled. 500 is the default "voice," 700 is for emphasis, 400 for body, 600 for navigation
## 4. Component Stylings
### Buttons
Ferrari's buttons are minimal white rectangles with near-zero radius — the CTA philosophy is "architecture, not decoration."
**Primary CTA (White)** — The default action button:
- Default: bg `#FFFFFF`, text `#000000`, fontSize 16px (FerrariSans), letterSpacing 1.28px, padding 12px 10px, borderRadius 2px, border 1px solid `#000000`
- Hover: bg `#1EAEDB` (Teal), text `#FFFFFF`, opacity 0.9
- Focus: bg `#1EAEDB`, text `#FFFFFF`, border 1px solid `#FFFFFF`, outline 2px solid `#000000`, opacity 0.9
- Used for: "Configure" actions, secondary calls to action on light backgrounds
**Subscribe CTA (Red)** — The high-emphasis action button:
- Default: bg `#DA291C` (Ferrari Red), text `#FFFFFF`, borderRadius 2px, padding 12px 10px
- Used for: Newsletter subscribe, primary conversion actions on dark backgrounds
- The only button that uses Ferrari Red — reserved for maximum visual priority
**Ghost Button (White Border)** — For dark backgrounds:
- Default: bg transparent, text `#FFFFFF`, border 1px solid `#FFFFFF`, borderRadius 2px, padding 12px 10px
- Hover: bg `#1EAEDB` (Teal), text `#FFFFFF`, opacity 0.9
- Focus: same as Primary CTA focus state
- Used for: Actions overlaid on dark imagery and cinematic sections
**Text Link** — Inline navigation:
- Default: text `#181818` (on light surfaces) or `#FFFFFF` (on dark), no border, no background
- Hover: color shifts to `#3860BE` (Link Hover Blue), decoration removes underline
- White variant on dark surfaces uses underline decoration by default
- FerrariSans or Body-Font depending on context (Body-Font for uppercase label links)
### Cards & Containers
**Editorial Card** (Content sections):
- Background: white
- Border: none
- Shadow: none
- Layout: image above, heading + caption below
- Image treatment: full-width within card, no rounded corners on image
- Text: FerrariSans heading (16–24px) + Body-Font caption (12–13px uppercase)
**Dark Cinematic Card** (Hero/feature sections):
- Background: `#000000` (Absolute Black)
- Full-bleed imagery with text overlay
- No border, no shadow — the darkness IS the container
- Text: white, positioned with careful negative space
**Vehicle Lineup** (Model carousel):
- Horizontal scrollable row of vehicle thumbnails
- Each vehicle on a neutral/white background
- Navigation: arrow buttons + dot indicators
- Background shifts to showcase the selected model's color context
### Inputs & Forms
**Newsletter Input** (Footer section):
- Background: transparent on dark surface
- Text: white
- Border: 1px solid `#CCCCCC`
- Placeholder: `#969696` (Silver Gray)
- Focus: border color transitions (standard browser focus ring)
- Label: Body-Font uppercase, 12px, 1px letter-spacing
**Cookie Consent** (Modal):
- Background: white
- Border radius: 8px (dialog)
- Shadow: `rgb(153, 153, 153) 1px 1px 1px 0px`
- Buttons: oversized (45px Arial), white bg with black border
- Uses standard PrimeReact/Element Plus modal framework
### Navigation
- **Desktop**: Prancing Horse logo centered at top of page, primary navigation below — not a traditional horizontal nav bar but a full-width header block on black background
- **Logo**: Centered Prancing Horse emblem (44×42px) on absolute black — the single most prominent UI element
- **Links**: FerrariSans, 13px, weight 600, white text on dark backgrounds
- **Mobile**: Hamburger collapse to vertical navigation drawer
- **Footer**: Multi-column layout on `#303030` (Dark Surface) with category links in Body-Font uppercase
- **No sticky nav behavior** observed — the page scrolls naturally with the header moving off-screen
### Image Treatment
- **Hero**: Full-width editorial photography on black backgrounds — concept cars in atmospheric studio lighting, editorial portraits with cinematic composition
- **Aspect ratios**: Mixed — landscape (16:9) for hero sections, near-square for portrait/driver imagery, wide panoramic for vehicle lineups
- **Full-bleed vs padded**: Hero images are full-bleed edge-to-edge; editorial content images are padded within white containers
- **Lazy loading**: Below-fold sections use progressive loading (PrimeReact framework handles this)
- **Image quality**: High-resolution photography with studio lighting — no user-generated or lifestyle imagery. Every image is art-directed
### Carousel Component
- Editorial carousel with multiple slides
- Dot indicators for slide position
- Arrow navigation (left/right) at slide edges
- Auto-advancing with manual override
- Content: mixed editorial — event recaps, model launches, racing highlights
## 5. Layout Principles
### Spacing System
- **Base unit**: 8px (detected system base)
- **Scale**: 1px, 2px, 4px, 5px, 6px, 9px, 10px, 11.2px, 12px, 13px, 15px, 16px, 19px, 20px, 25px
- **Button padding**: 12px vertical, 10px horizontal — compact and precise
- **Section padding**: Generous vertical spacing (40–80px estimated) between major content blocks
- **Card gaps**: 16–20px between grid items
- **Footer padding**: 25px horizontal sections within the dark footer block
### Grid & Container
- **Max width**: 1920px (largest breakpoint) with content constraining at narrower widths
- **Hero**: Full-bleed on black, content centered
- **Editorial sections**: 2-column layouts with image + text, alternating sides
- **Vehicle lineup**: Horizontal scroll/carousel, 5–6 models visible at desktop width
- **Footer**: 4-column grid for link categories
### Whitespace Philosophy
Ferrari treats white space as a gallery wall. Each section — whether a concept car render on black void or a pair of F1 drivers on neutral gray — is given its own "room" of breathing space. The alternating black/white sections create a pacing rhythm: dark = immersive moment, white = editorial content, dark = immersive moment. This cadence makes scrolling feel like turning pages in a luxury publication. White space between editorial cards is moderate (not Tesla-extreme) because Ferrari is telling stories, not exhibiting single objects.
### Border Radius Scale
| Value | Context |
|-------|---------|
| 1px | Subtle softening on small inline elements (spans) |
| 2px | Default for buttons, inputs, and interactive elements — barely perceptible, razor-precision |
| 8px | Modal dialogs and overlay containers — the "softest" structural radius |
| 50% | Circular elements: carousel dots, avatar thumbnails, slider handles |
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Level 0 (Flat) | No shadow, no border | Default state for all content sections and cards |
| Level 1 (Subtle) | `rgb(153, 153, 153) 1px 1px 1px 0px` | Rare — cookie consent dialogs and dropdown menus |
| Level 2 (Overlay) | `hsla(0, 0%, 7%, 0.8)` backdrop | Modal overlays and image caption backgrounds |
| Level 3 (Border) | `1px solid #CCCCCC` | Input fields, form containers — depth through delineation not shadow |
### Shadow Philosophy
Ferrari's approach to elevation is nearly as flat as Tesla's, but with a different rationale. Where Tesla avoids shadows for minimalism, Ferrari avoids them because the editorial photography provides all the visual depth needed. The single shadow token (`rgb(153, 153, 153) 1px 1px 1px 0px`) is extremely subtle — a 1-pixel whisper used only in utilitarian contexts like consent dialogs. The site communicates hierarchy through three strategies:
1. **Surface color contrast**: Black sections vs. white sections create unmistakable layering
2. **Overlay transparency**: The `--f-color-overlay-darker` at 80% opacity creates depth without shadow
3. **Photographic depth**: Studio-lit car imagery with reflections, ground shadows, and atmospheric haze provides all the visual dimensionality
### Decorative Depth
- No UI gradients, no glows, no blur effects on interface elements
- The Prancing Horse logo on black creates a "floating in void" effect through pure contrast — no glow or shadow needed
- Dark-to-light section transitions are hard cuts, not gradient blends — reinforcing the editorial page-turn metaphor
## 7. Do's and Don'ts
### Do
- Use Ferrari Red (`#DA291C`) sparingly — only for primary CTAs and brand-critical moments. Its power comes from restraint
- Alternate between black cinematic sections and white editorial sections to create the signature chiaroscuro rhythm
- Use FerrariSans at weight 500 as the default heading voice — it's the typographic equivalent of the engine note
- Apply Body-Font in uppercase with 1px letter-spacing for all labels, category tags, and structural annotations
- Keep border-radius at 2px for all interactive elements — razor precision, not rounded friendliness
- Let photography carry the emotional weight — every image should be art-directed studio quality
- Use the Prancing Horse emblem as a standalone hero element on black — never crowd it with adjacent content
- Maintain the 12px/10px button padding ratio — compact, purposeful, no excess
- Use `#181818` (Near Black) for body text instead of pure `#000000` — the subtle warmth improves readability
- Reserve the yellow accents (`#FFF200`, `#F6E500`) strictly for motorsport and racing heritage contexts
### Don't
- Scatter Ferrari Red across the interface as decoration — it's a CTA signal, not a theme color
- Use rounded-pill buttons or large border-radii — the 2px precision is non-negotiable
- Add box-shadows to cards or content containers — depth comes from surface color contrast and photography
- Mix FerrariSans and Body-Font within the same text block — they serve separate hierarchical functions
- Use colorful backgrounds (blue, green, etc.) for sections — the palette is exclusively black/white/gray with red and yellow accents
- Apply text transforms to FerrariSans headings — uppercase is reserved for Body-Font labels only
- Display low-quality or user-generated imagery — every photograph must meet editorial standards
- Use the Link Hover Blue (`#3860BE`) for anything other than interactive hover states — it's not a brand color
- Create busy layouts with multiple competing focal points — each section should have one clear story
- Override the semantic color system (warning, success, info) with brand colors — `#F13A2C` warning is deliberately different from `#DA291C` brand red
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile Small | ≤375px | Single-column, minimal padding (12px), stacked navigation, hero text scales to ~18px, full-width CTAs |
| Mobile | 376–600px | Single-column, slightly larger padding (16px), hamburger nav, body text at 13px |
| Tablet Small | 601–768px | 2-column editorial grid begins, hero images maintain full-width, footer switches to 2-column |
| Tablet | 769–960px | Full 2-column layout, carousel shows 3 vehicles, padding increases to 20px |
| Desktop | 961–1280px | Full navigation, 2-column editorial with larger imagery, vehicle lineup shows 5 models |
| Large Desktop | 1281–1920px | Maximum content width, generous whitespace, hero photography at full cinematic scale |
### Touch Targets
- Primary CTA buttons: minimum 44px height with 12px vertical padding (meets WCAG AAA 44×44px target)
- Navigation links: 13px text with 1.50 line-height and adequate spacing between items
- Carousel arrows: 44px+ touch targets at viewport edges
- Footer links: grouped with sufficient vertical spacing (16–20px) for touch accuracy
### Collapsing Strategy
- **Navigation**: Full horizontal nav collapses to centered Prancing Horse logo + hamburger menu on mobile
- **Editorial sections**: 2-column image+text layouts collapse to single-column with image stacking above text
- **Vehicle lineup**: Horizontal carousel maintains scroll behavior but reduces visible models from 5 to 2–3
- **Footer**: 4-column link grid collapses to 2-column on tablet, single-column accordion on mobile
- **Hero carousel**: Full-width at all breakpoints, dot indicators and arrows scale proportionally
- **Spacing reduction**: Section padding reduces from 40–80px (desktop) to 20–40px (mobile), maintaining proportional breathing room
### Image Behavior
- Hero images: full-bleed at all breakpoints, using `object-fit: cover` to maintain cinematic composition
- Editorial images: responsive within their containers, maintaining aspect ratio
- Vehicle lineup: thumbnail size scales but maintains consistent car-to-frame proportions
- Art direction: mobile crops may tighten on vehicle subjects, reducing environmental context
- Lazy loading: PrimeReact handles progressive image loading for below-fold content
## 9. Agent Prompt Guide
### Quick Color Reference

### Iteration Guide
When refining existing screens generated with this design system:
1. Focus on ONE component at a time — Ferrari's editorial rhythm means each section is a self-contained vignette
2. Reference specific color names and hex codes from this document — the palette is small but each color has a precise role
3. Use natural language descriptions, not CSS values — "razor-sharp 2px corners" conveys intent better than "border-radius: 2px"
4. Describe the desired "feel" alongside specific measurements — "editorial magazine page-turn between sections" communicates the layout philosophy better than "margin-bottom: 80px"
5. Always maintain the chiaroscuro contrast — if a section feels flat, check whether it needs to be on black or white to maintain the alternating rhythm
6. Reserve Ferrari Red for ONE element per screen — if red appears in more than one place, it loses its authority

# Design System Inspired by Figma
> Category: Design & Creative
> Collaborative design tool. Vibrant multi-color, playful yet professional.
## 1. Visual Theme & Atmosphere
Figma's interface is the design tool that designed itself — a masterclass in typographic sophistication where a custom variable font (figmaSans) modulates between razor-thin (weight 320) and bold (weight 700) with stops at unusual intermediates (330, 340, 450, 480, 540) that most type systems never explore. This granular weight control gives every text element a precisely calibrated visual weight, creating hierarchy through micro-differences rather than the blunt instrument of "regular vs bold."
The page presents a fascinating duality: the interface chrome is strictly black-and-white (literally only `#000000` and `#ffffff` detected as colors), while the hero section and product showcases explode with vibrant multi-color gradients — electric greens, bright yellows, deep purples, hot pinks. This separation means the design system itself is colorless, treating the product's colorful output as the hero content. Figma's marketing page is essentially a white gallery wall displaying colorful art.
What makes Figma distinctive beyond the variable font is its circle-and-pill geometry. Buttons use 50px radius (pill) or 50% (perfect circle for icon buttons), creating an organic, tool-palette-like feel. The dashed-outline focus indicator (`dashed 2px`) is a deliberate design choice that echoes selection handles in the Figma editor itself — the website's UI language references the product's UI language.
**Key Characteristics:**
- Custom variable font (figmaSans) with unusual weight stops: 320, 330, 340, 450, 480, 540, 700
- Strictly black-and-white interface chrome — color exists only in product content
- figmaMono for uppercase technical labels with wide letter-spacing
- Pill (50px) and circular (50%) button geometry
- Dashed focus outlines echoing Figma's editor selection handles
- Vibrant multi-color hero gradients (green, yellow, purple, pink)
- OpenType `"kern"` feature enabled globally
- Negative letter-spacing throughout — even body text at -0.14px to -0.26px
## 2. Color Palette & Roles
### Primary
- **Pure Black** (`#000000`): All text, all solid buttons, all borders. The sole "color" of the interface.
- **Pure White** (`#ffffff`): All backgrounds, white buttons, text on dark surfaces. The other half of the binary.
*Note: Figma's marketing site uses ONLY these two colors for its interface layer. All vibrant colors appear exclusively in product screenshots, hero gradients, and embedded content.*
### Surface & Background
- **Pure White** (`#ffffff`): Primary page background and card surfaces.
- **Glass Black** (`rgba(0, 0, 0, 0.08)`): Subtle dark overlay for secondary circular buttons and glass effects.
- **Glass White** (`rgba(255, 255, 255, 0.16)`): Frosted glass overlay for buttons on dark/colored surfaces.
### Gradient System
- **Hero Gradient**: A vibrant multi-stop gradient using electric green, bright yellow, deep purple, and hot pink. This gradient is the visual signature of the hero section — it represents the creative possibilities of the tool.
- **Product Section Gradients**: Individual product areas (Design, Dev Mode, Prototyping) may use distinct color themes in their showcases.
## 3. Typography Rules
### Font Family
- **Primary**: `figmaSans`, with fallbacks: `figmaSans Fallback, SF Pro Display, system-ui, helvetica`
- **Monospace / Labels**: `figmaMono`, with fallbacks: `figmaMono Fallback, SF Mono, menlo`
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display / Hero | figmaSans | 86px (5.38rem) | 400 | 1.00 (tight) | -1.72px | Maximum impact, extreme tracking |
| Section Heading | figmaSans | 64px (4rem) | 400 | 1.10 (tight) | -0.96px | Feature section titles |
| Sub-heading | figmaSans | 26px (1.63rem) | 540 | 1.35 | -0.26px | Emphasized section text |
| Sub-heading Light | figmaSans | 26px (1.63rem) | 340 | 1.35 | -0.26px | Light-weight section text |
| Feature Title | figmaSans | 24px (1.5rem) | 700 | 1.45 | normal | Bold card headings |
| Body Large | figmaSans | 20px (1.25rem) | 330–450 | 1.30–1.40 | -0.1px to -0.14px | Descriptions, intros |
| Body / Button | figmaSans | 16px (1rem) | 330–400 | 1.40–1.45 | -0.14px to normal | Standard body, nav, buttons |
| Body Light | figmaSans | 18px (1.13rem) | 320 | 1.45 | -0.26px to normal | Light-weight body text |
| Mono Label | figmaMono | 18px (1.13rem) | 400 | 1.30 (tight) | 0.54px | Uppercase section labels |
| Mono Small | figmaMono | 12px (0.75rem) | 400 | 1.00 (tight) | 0.6px | Uppercase tiny tags |
### Principles
- **Variable font precision**: figmaSans uses weights that most systems never touch — 320, 330, 340, 450, 480, 540. This creates hierarchy through subtle weight differences rather than dramatic jumps. The difference between 330 and 340 is nearly imperceptible but structurally significant.
- **Light as the base**: Most body text uses 320–340 (lighter than typical 400 "regular"), creating an ethereal, airy reading experience that matches the design-tool aesthetic.
- **Kern everywhere**: Every text element enables OpenType `"kern"` feature — kerning is not optional, it's structural.
- **Negative tracking by default**: Even body text uses -0.1px to -0.26px letter-spacing, creating universally tight text. Display text compresses further to -0.96px and -1.72px.
- **Mono for structure**: figmaMono in uppercase with positive letter-spacing (0.54px–0.6px) creates technical signpost labels.
## 4. Component Stylings
### Buttons
**Black Solid (Pill)**
- Background: Pure Black (`#000000`)

- Secondary action on dark/colored surfaces
### Cards & Containers
- Background: Pure White
- Border: none or minimal
- Radius: 6px (small containers), 8px (images, cards, dialogs)
- Shadow: subtle to medium elevation effects
- Product screenshots as card content
### Navigation
- Clean horizontal nav on white
- Logo: Figma wordmark in black
- Product tabs: pill-shaped (50px) tab navigation
- Links: black text, underline 1px decoration
- CTA: Black pill button
- Hover: text color via CSS variable
### Distinctive Components
**Product Tab Bar**
- Horizontal pill-shaped tabs (50px radius)
- Each tab represents a Figma product area (Design, Dev Mode, Prototyping, etc.)
- Active tab highlighted
**Hero Gradient Section**
- Full-width vibrant multi-color gradient background
- White text overlay with 86px display heading
- Product screenshots floating within the gradient
**Dashed Focus Indicators**
- All interactive elements use `dashed 2px` outline on focus
- References the selection handles in the Figma editor
- A meta-design choice connecting website and product
## 5. Layout Principles
### Spacing System
- Base unit: 8px
- Scale: 1px, 2px, 4px, 4.5px, 8px, 10px, 12px, 16px, 18px, 24px, 32px, 40px, 46px, 48px, 50px
### Grid & Container
- Max container width: up to 1920px
- Hero: full-width gradient with centered content
- Product sections: alternating showcases
- Footer: dark full-width section
- Responsive from 559px to 1920px
### Whitespace Philosophy
- **Gallery-like pacing**: Generous spacing lets each product section breathe as its own exhibit.
- **Color sections as visual breathing**: The gradient hero and product showcases provide chromatic relief between the monochrome interface sections.
### Border Radius Scale
- Minimal (2px): Small link elements
- Subtle (6px): Small containers, dividers
- Comfortable (8px): Cards, images, dialogs
- Pill (50px): Tab buttons, CTAs
- Circle (50%): Icon buttons, circular elements
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Page background, most text |
| Surface (Level 1) | White card on gradient/dark section | Cards, product showcases |
| Elevated (Level 2) | Subtle shadow | Floating cards, hover states |
**Shadow Philosophy**: Figma uses shadows sparingly. The primary depth mechanisms are **background contrast** (white content on colorful/dark sections) and the inherent dimensionality of the product screenshots themselves.
## 7. Do's and Don'ts
### Do
- Use figmaSans with precise variable weights (320–540) — the granular weight control IS the design
- Keep the interface strictly black-and-white — color comes from product content only
- Use pill (50px) and circular (50%) geometry for all interactive elements
- Apply dashed 2px focus outlines — the signature accessibility pattern
- Enable `"kern"` feature on all text
- Use figmaMono in uppercase with positive letter-spacing for labels
- Apply negative letter-spacing throughout (-0.1px to -1.72px)
### Don't
- Don't add interface colors — the monochrome palette is absolute
- Don't use standard font weights (400, 500, 600, 700) — use the variable font's unique stops (320, 330, 340, 450, 480, 540)
- Don't use sharp corners on buttons — pill and circular geometry only
- Don't use solid focus outlines — dashed is the signature
- Don't increase body font weight above 450 — the light-weight aesthetic is core
- Don't use positive letter-spacing on body text — it's always negative
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Small Mobile | <560px | Compact layout, stacked |
| Tablet | 560–768px | Minor adjustments |
| Small Desktop | 768–960px | 2-column layouts |
| Desktop | 960–1280px | Standard layout |
| Large Desktop | 1280–1440px | Expanded |
| Ultra-wide | 1440–1920px | Maximum width |
### Collapsing Strategy
- Hero text: 86px → 64px → 48px
- Product tabs: horizontal scroll on mobile
- Feature sections: stacked single column
- Footer: multi-column → stacked
## 9. Agent Prompt Guide
### Quick Color Reference
- Everything: "Pure Black (#000000)" and "Pure White (#ffffff)"
- Glass Dark: "rgba(0, 0, 0, 0.08)"
- Glass Light: "rgba(255, 255, 255, 0.16)"
### Example Component Prompts
- "Create a hero on a vibrant multi-color gradient (green, yellow, purple, pink). Headline at 86px figmaSans weight 400, line-height 1.0, letter-spacing -1.72px. White text. White pill CTA button (50px radius, 8px 18px padding)."
- "Design a product tab bar with pill-shaped buttons (50px radius). Active: Black bg, white text. Inactive: transparent, black text. figmaSans at 20px weight 480."
- "Build a section label: figmaMono 18px, uppercase, letter-spacing 0.54px, black text. Kern enabled."
- "Create body text at 20px figmaSans weight 330, line-height 1.40, letter-spacing -0.14px. Pure Black on white."
### Iteration Guide
1. Use variable font weight stops precisely: 320, 330, 340, 450, 480, 540, 700
2. Interface is always black + white — never add colors to chrome
3. Dashed focus outlines, not solid
4. Letter-spacing is always negative on body, always positive on mono labels
5. Pill (50px) for buttons/tabs, circle (50%) for icon buttons

# Design System Inspired by Flat
> Category: Modern & Minimal
> Two-dimensional minimalist style with vibrant colors, clean typography, and no 3D effects for fast, user-friendly interfaces.
## 1. Visual Theme & Atmosphere
Two-dimensional minimalist style with vibrant colors, clean typography, and no 3D effects for fast, user-friendly interfaces.
- **Visual style:** minimal, enterprise
- **Color stance:** primary, neutral, success, warning, danger
- **Design intent:** Keep outputs recognizable to this style family while preserving usability and readability.
## 2. Color
- **Primary:** `#F2673C` — Token from style foundations.
- **Secondary:** `#8B5CF6` — Token from style foundations.
- **Success:** `#16A34A` — Token from style foundations.
- **Warning:** `#D97706` — Token from style foundations.
- **Danger:** `#DC2626` — Token from style foundations.
- **Surface:** `#FFFFFF` — Token from style foundations.
- **Text:** `#111827` — Token from style foundations.
- **Neutral:** `#FFFFFF` — Derived from the surface token for official format compatibility.
- Favor Primary (#F2673C) for CTA emphasis.
- Use Surface (#FFFFFF) for large backgrounds and cards.
- Keep body copy on Text (#111827) for legibility.
## 3. Typography
- **Scale:** 12/14/16/20/24/32
- **Families:** primary=Inter, display=Inter, mono=JetBrains Mono
- **Weights:** 100, 200, 300, 400, 500, 600, 700, 800, 900
- Headings should carry the style personality; body text should optimize scanability and contrast.
## 4. Spacing & Grid
- **Spacing scale:** 4/8/12/16/24/32
- Keep vertical rhythm consistent across sections and components.
- Align columns and modules to a predictable grid; avoid ad-hoc offsets.
## 5. Layout & Composition
- Prefer clear content blocks with consistent internal padding.
- Keep hierarchy obvious: headline → support text → primary action.
- Use whitespace to separate concerns before adding borders or shadows.
## 6. Components
- Buttons: primary action uses `#F2673C`; secondary actions stay neutral.
- Inputs: strong focus-visible states, clear labels, and predictable error messaging.
- Cards/sections: use consistent radii, spacing, and elevation strategy across the page.
## 7. Motion & Interaction
- Use subtle transitions that emphasize Primary (#F2673C) as the interaction signal.
- Default to short, purposeful transitions (150–250ms) with stable easing.
- Ensure hover, focus-visible, active, disabled, and loading states are explicit.
## 8. Voice & Brand
- Tone should reflect the visual style: concise, confident, and product-specific.
- Keep microcopy action-oriented and avoid generic filler language.
- Preserve the style identity in headlines while keeping UI labels literal and clear.
## 9. Anti-patterns
- Do not introduce off-palette colors when an existing token can solve the problem.
- Do not flatten hierarchy by using the same type size/weight for all text.
- Do not add decorative effects that reduce readability or accessibility.
- Do not mix unrelated visual metaphors in the same interface.

# Design System Inspired by Framer
> Category: Design & Creative
> Website builder. Bold black and blue, motion-first, design-forward.
## 1. Visual Theme & Atmosphere
Framer's website is a cinematic, tool-obsessed dark canvas that radiates the confidence of a design tool built by designers who worship craft. The entire experience is drenched in pure black — not a warm charcoal or a cozy dark gray, but an absolute void (`#000000`) that makes every element, every screenshot, every typographic flourish feel like it's floating in deep space. This is a website that treats its own product UI as the hero art, embedding full-fidelity screenshots and interactive demos directly into the narrative flow.
The typography is the signature move: GT Walsheim with aggressively tight letter-spacing (as extreme as -5.5px on 110px display text) creates headlines that feel compressed, kinetic, almost spring-loaded — like words under pressure that might expand at any moment. The transition to Inter for body text is seamless, with extensive OpenType feature usage (`cv01`, `cv05`, `cv09`, `cv11`, `ss03`, `ss07`) that gives even small text a refined, custom feel. Framer Blue (`#0099ff`) is deployed sparingly but decisively — as link color, border accents, and subtle ring shadows — creating a cold, electric throughline against the warm-less black.
The overall effect is a nightclub for web designers: dark, precise, seductive, and unapologetically product-forward. Every section exists to showcase what the tool can do, with the website itself serving as proof of concept.
**Key Characteristics:**
- Pure black (`#000000`) void canvas — absolute dark, not warm or gray-tinted
- GT Walsheim display font with extreme negative letter-spacing (-5.5px at 110px)
- Framer Blue (`#0099ff`) as the sole accent color — cold, electric, precise
- Pill-shaped buttons (40px–100px radius) — no sharp corners on interactive elements
- Product screenshots as hero art — the tool IS the marketing
- Frosted glass button variants using `rgba(255, 255, 255, 0.1)` on dark surfaces
- Extensive OpenType feature usage across Inter for refined micro-typography
## 2. Color Palette & Roles
### Primary
- **Pure Black** (`#000000`): Primary background, the void canvas that defines Framer's dark-first identity
- **Pure White** (`#ffffff`): Primary text color on dark surfaces, button text on accent backgrounds
- **Framer Blue** (`#0099ff`): Primary accent color — links, borders, ring shadows, interactive highlights
### Secondary & Accent
- **Muted Silver** (`#a6a6a6`): Secondary text, subdued labels, dimmed descriptions on dark surfaces
- **Near Black** (`#090909`): Elevated dark surface, shadow ring color for subtle depth separation
### Surface & Background
- **Void Black** (`#000000`): Page background, primary canvas
- **Frosted White** (`rgba(255, 255, 255, 0.1)`): Translucent button backgrounds, glass-effect surfaces on dark
- **Subtle White** (`rgba(255, 255, 255, 0.5)`): Slightly more opaque frosted elements for hover states
### Neutrals & Text
- **Pure White** (`#ffffff`): Heading text, high-emphasis body text
- **Muted Silver** (`#a6a6a6`): Body text, descriptions, secondary information
- **Ghost White** (`rgba(255, 255, 255, 0.6)`): Tertiary text, placeholders on dark surfaces
### Semantic & Accent
- **Framer Blue** (`#0099ff`): Links, interactive borders, focus rings
- **Blue Glow** (`rgba(0, 153, 255, 0.15)`): Focus ring shadow, subtle blue halo around interactive elements
- **Default Link Blue** (`#0000ee`): Standard browser link color (used sparingly in content areas)
### Gradient System
- No prominent gradient usage — Framer relies on pure flat black surfaces with occasional blue-tinted glows for depth
- Subtle radial glow effects behind product screenshots using Framer Blue at very low opacity
## 3. Typography Rules
### Font Family
- **Display**: `GT Walsheim Framer Medium` / `GT Walsheim Medium` — custom geometric sans-serif, weight 500. Fallbacks: `GT Walsheim Framer Medium Placeholder`, system sans-serif
- **Body/UI**: `Inter Variable` / `Inter` — variable sans-serif with extensive OpenType features. Fallbacks: `Inter Placeholder`, `-apple-system`, `system-ui`
- **Accent**: `Mona Sans` — GitHub's open-source font, used for select elements at ultra-light weight (100)
- **Monospace**: `Azeret Mono` — companion mono for code and technical labels
- **Rounded**: `Open Runde` — small rounded companion font for micro-labels
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display Hero | GT Walsheim Framer Medium | 110px | 500 | 0.85 | -5.5px | Extreme negative tracking, compressed impact |
| Section Display | GT Walsheim Medium | 85px | 500 | 0.95 | -4.25px | OpenType: ss02, tnum |
| Section Heading | GT Walsheim Medium | 62px | 500 | 1.00 | -3.1px | OpenType: ss02 |
| Feature Heading | GT Walsheim Medium | 32px | 500 | 1.13 | -1px | Tightest of the smaller headings |
| Accent Display | Mona Sans | 61.5px | 100 | 1.00 | -3.1px | Ultra-light weight, ethereal |
| Card Title | Inter Variable | 24px | 400 | 1.30 | -0.01px | OpenType: cv01, cv05, cv09, cv11, ss03, ss07 |
| Feature Title | Inter | 22px | 700 | 1.20 | -0.8px | OpenType: cv05 |
| Sub-heading | Inter | 20px | 600 | 1.20 | -0.8px | OpenType: cv01, cv09 |
| Body Large | Inter Variable | 18px | 400 | 1.30 | -0.01px | OpenType: cv01, cv05, cv09, cv11, ss03, ss07 |
| Body | Inter Variable | 15px | 400 | 1.30 | -0.01px | OpenType: cv11 |
| Nav/UI | Inter Variable | 15px | 400 | 1.00 | -0.15px | OpenType: cv06, cv11, dlig, ss03 |
| Body Readable | Inter Framer Regular | 14px | 400 | 1.60 | normal | Long-form body text |
| Caption | Inter Variable | 14px | 400 | 1.40 | normal | OpenType: cv01, cv06, cv09, cv11, ss03, ss07 |
| Label | Inter | 13px | 500 | 1.60 | normal | OpenType: cv06, cv11, ss03 |
| Small Caption | Inter Variable | 12px | 400 | 1.40 | normal | OpenType: cv01, cv06, cv09, cv11, ss03, ss07 |
| Micro Code | Azeret Mono | 10.4px | 400 | 1.60 | normal | OpenType: cv06, cv11, ss03 |
| Badge | Open Runde | 9px | 600 | 1.11 | normal | OpenType: cv01, cv09 |
| Micro Uppercase | Inter Variable | 7px | 400 | 1.00 | 0.21px | uppercase transform |
### Principles
- **Compression as personality**: GT Walsheim's extreme negative letter-spacing (-5.5px at 110px) is the defining typographic gesture — headlines feel spring-loaded, urgent, almost breathless
- **OpenType maximalism**: Inter is deployed with 6+ OpenType features simultaneously (`cv01`, `cv05`, `cv09`, `cv11`, `ss03`, `ss07`), creating a subtly custom feel even at body sizes
- **Weight restraint on display**: All GT Walsheim usage is weight 500 (medium) — never bold, never regular. This creates a confident-but-not-aggressive display tone
- **Ultra-tight line heights**: Display text at 0.85 line-height means letters nearly overlap vertically — intentional density that rewards reading at arm's length
## 4. Component Stylings
### Buttons
- **Frosted Pill**: `rgba(255, 255, 255, 0.1)` background, black text (`#000000`), pill shape (40px radius). The glass-effect button that lives on dark surfaces — translucent, ambient, subtle
- **Solid White Pill**: `rgb(255, 255, 255)` background, black text (`#000000`), full pill shape (100px radius), padding `10px 15px`. The primary CTA — clean, high-contrast on dark, unmissable
- **Ghost**: No visible background, white text, relies on text styling alone. Hover reveals subtle frosted background
- **Transition**: Scale-based animations (matrix transform with 0.85 scale factor), opacity transitions for reveal effects
### Cards & Containers
- **Dark Surface Card**: Black or near-black (`#090909`) background, `rgba(0, 153, 255, 0.15) 0px 0px 0px 1px` blue ring shadow border, rounded corners (10px–15px radius)
- **Elevated Card**: Multi-layer shadow — `rgba(255, 255, 255, 0.1) 0px 0.5px 0px 0.5px` (subtle top highlight) + `rgba(0, 0, 0, 0.25) 0px 10px 30px` (deep ambient shadow)
- **Product Screenshots**: Full-width or padded within dark containers, 8px–12px border-radius for software UI previews
- **Hover**: Subtle glow increase on Framer Blue ring shadow, or brightness shift on frosted surfaces
### Inputs & Forms
- Minimal form presence on the marketing site
- Input fields follow dark theme: dark background, subtle border, white text
- Focus state: Framer Blue (`#0099ff`) ring border, `1px solid #0099ff`
- Placeholder text in `rgba(255, 255, 255, 0.4)`
### Navigation
- **Dark floating nav bar**: Black background with frosted glass effect, white text links
- **Nav links**: Inter at 15px, weight 400, white text with subtle hover opacity change
- **CTA button**: Pill-shaped, white or frosted, positioned at right end of nav
- **Mobile**: Collapses to hamburger menu, maintains dark theme
- **Sticky behavior**: Nav remains fixed at top on scroll
### Image Treatment
- **Product screenshots as hero art**: Full-width embedded UI screenshots with rounded corners (8px–12px)
- **Dark-on-dark composition**: Screenshots placed on black backgrounds with subtle shadow for depth separation
- **16:9 and custom aspect ratios**: Product demos fill their containers
- **No decorative imagery**: All images are functional — showing the tool, the output, or the workflow
### Trust & Social Proof
- Customer logos and testimonials in muted gray on dark surfaces
- Minimal ornamentation — the product screenshots serve as the trust signal
## 5. Layout Principles
### Spacing System
- **Base unit**: 8px
- **Scale**: 1px, 2px, 3px, 4px, 5px, 6px, 8px, 10px, 12px, 15px, 20px, 30px, 35px
- **Section padding**: Large vertical spacing (80px–120px between sections)
- **Card padding**: 15px–30px internal padding
- **Component gaps**: 8px–20px between related elements
### Grid & Container
- **Max width**: ~1200px container, centered
- **Column patterns**: Full-width hero, 2-column feature sections, single-column product showcases
- **Asymmetric layouts**: Feature sections often pair text (40%) with screenshot (60%)
### Whitespace Philosophy
- **Breathe through darkness**: Generous vertical spacing between sections — the black background means whitespace manifests as void, creating dramatic pauses between content blocks
- **Dense within, spacious between**: Individual components are tightly composed (tight line-heights, compressed text) but float in generous surrounding space
- **Product-first density**: Screenshot areas are allowed to be dense and information-rich, contrasting with the sparse marketing text
### Border Radius Scale
- **1px**: Micro-elements, nearly squared precision edges
- **5px–7px**: Small UI elements, image thumbnails — subtly softened
- **8px**: Standard component radius — code blocks, buttons, interactive elements
- **10px–12px**: Cards, product screenshots — comfortably rounded
- **15px–20px**: Large containers, feature cards — generously rounded
- **30px–40px**: Navigation pills, pagination — noticeably rounded
- **100px**: Full pill shape — primary CTAs, tag elements
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Level 0 (Flat) | No shadow, pure black surface | Page background, empty areas |
| Level 1 (Ring) | `rgba(0, 153, 255, 0.15) 0px 0px 0px 1px` | Card borders, interactive element outlines — Framer Blue glow ring |
| Level 2 (Contained) | `rgb(9, 9, 9) 0px 0px 0px 2px` | Near-black ring for subtle containment on dark surfaces |
| Level 3 (Floating) | `rgba(255, 255, 255, 0.1) 0px 0.5px 0px 0.5px, rgba(0, 0, 0, 0.25) 0px 10px 30px` | Elevated cards, floating elements — subtle white top-edge highlight + deep ambient shadow |
### Shadow Philosophy
Framer's elevation system is inverted from traditional light-theme designs. Instead of darker shadows on light backgrounds, Framer uses:
- **Blue-tinted ring shadows** at very low opacity (0.15) for containment — a signature move that subtly brands every bordered element
- **White edge highlights** (0.5px) on the top edge of elevated elements — simulating light hitting the top surface
- **Deep ambient shadows** for true floating elements — `rgba(0, 0, 0, 0.25)` at large spread (30px)
### Decorative Depth
- **Blue glow auras**: Subtle Framer Blue (`#0099ff`) radial gradients behind key interactive areas
- **No background blur/glassmorphism**: Despite the frosted button effect, there's no heavy glass blur usage — the translucency is achieved through simple rgba opacity
## 7. Do's and Don'ts
### Do
- Use pure black (`#000000`) as the primary background — not dark gray, not charcoal
- Apply extreme negative letter-spacing on GT Walsheim display text (-3px to -5.5px)
- Keep all buttons pill-shaped (40px+ radius) — never use squared or slightly-rounded buttons
- Use Framer Blue (`#0099ff`) exclusively for interactive accents — links, borders, focus states
- Deploy `rgba(255, 255, 255, 0.1)` for frosted glass surfaces on dark backgrounds
- Maintain GT Walsheim at weight 500 only — the medium weight IS the brand
- Use extensive OpenType features on Inter text (cv01, cv05, cv09, cv11, ss03, ss07)
- Let product screenshots be the visual centerpiece — the tool markets itself
- Apply blue ring shadows (`rgba(0, 153, 255, 0.15) 0px 0px 0px 1px`) for card containment
### Don't
- Use warm dark backgrounds (no `#1a1a1a`, `#2d2d2d`, or brownish blacks)
- Apply bold (700+) weight to GT Walsheim display text — medium 500 only
- Introduce additional accent colors beyond Framer Blue — this is a one-accent-color system
- Use large border-radius on non-interactive elements (cards use 10px–15px, only buttons get 40px+)
- Add decorative imagery, illustrations, or icons — the product IS the illustration
- Use positive letter-spacing on headlines — everything is compressed, negative tracking
- Create heavy drop shadows — depth is communicated through subtle rings and minimal ambients
- Place light/white backgrounds behind content sections — the void is sacred
- Use serif or display-weight fonts — the system is geometric sans-serif only
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | <809px | Single column, stacked feature sections, reduced hero text (62px→40px), hamburger nav |
| Tablet | 809px–1199px | 2-column features begin, nav links partially visible, screenshots scale down |
| Desktop | >1199px | Full layout, expanded nav with all links + CTA, 110px display hero, side-by-side features |
### Touch Targets
- Pill buttons: minimum 40px height with 10px vertical padding — exceeds 44px WCAG minimum
- Nav links: 15px text with generous padding for touch accessibility
- Mobile CTA buttons: Full-width pills on mobile for easy thumb reach
### Collapsing Strategy
- **Navigation**: Full horizontal nav → hamburger menu at mobile breakpoint
- **Hero text**: 110px display → 85px → 62px → ~40px across breakpoints, maintaining extreme negative tracking proportionally
- **Feature sections**: Side-by-side (text + screenshot) → stacked vertically on mobile
- **Product screenshots**: Scale responsively within containers, maintaining aspect ratios
- **Section spacing**: Reduces proportionally — 120px desktop → 60px mobile
### Image Behavior
- Product screenshots are responsive, scaling within their container boundaries
- No art direction changes — same crops across breakpoints
- Dark background ensures screenshots maintain visual impact at any size
- Screenshots lazy-load as user scrolls into view
## 9. Agent Prompt Guide
### Quick Color Reference
- Primary Background: Void Black (`#000000`)
- Primary Text: Pure White (`#ffffff`)
- Accent/CTA: Framer Blue (`#0099ff`)
- Secondary Text: Muted Silver (`#a6a6a6`)
- Frosted Surface: Translucent White (`rgba(255, 255, 255, 0.1)`)
- Elevation Ring: Blue Glow (`rgba(0, 153, 255, 0.15)`)
### Example Component Prompts
- "Create a hero section on pure black background with 110px GT Walsheim heading in white, letter-spacing -5.5px, line-height 0.85, and a pill-shaped white CTA button (100px radius) with black text"
- "Design a feature card on black background with a 1px Framer Blue ring shadow border (rgba(0,153,255,0.15)), 12px border-radius, white heading in Inter at 22px weight 700, and muted silver (a6a6a6) body text"
- "Build a navigation bar with black background, white Inter text links at 15px, and a frosted pill button (rgba(255,255,255,0.1) background, 40px radius) as the CTA"
- "Create a product showcase section with a full-width screenshot embedded on black, 10px border-radius, subtle multi-layer shadow (white 0.5px top highlight + rgba(0,0,0,0.25) 30px ambient)"
- "Design a pricing card using pure black surface, Framer Blue (#0099ff) accent for the selected plan border, white text hierarchy (24px Inter bold heading, 14px regular body), and a solid white pill CTA button"
### Iteration Guide
When refining existing screens generated with this design system:
1. Focus on ONE component at a time — the dark canvas makes each element precious
2. Always verify letter-spacing on GT Walsheim headings — the extreme negative tracking is non-negotiable
3. Check that Framer Blue appears ONLY on interactive elements — never as decorative background or text color for non-links
4. Ensure all buttons are pill-shaped — any squared corner immediately breaks the Framer aesthetic
5. Test frosted glass surfaces by checking they have exactly `rgba(255, 255, 255, 0.1)` — too opaque looks like a bug, too transparent disappears

# Design System Inspired by GitHub
> Category: Developer Tools
> Code-forward platform. Functional density, blue-on-white precision, Primer foundations.
## 1. Visual Theme & Atmosphere
GitHub's surface is engineered, not decorated. Every pixel announces a stance: this is a tool for people who care about diffs, builds, and pull requests. The page background is a clean `#ffffff` (light) or `#0d1117` (dark), with content arranged on dense rectangular panes separated by hairline borders rather than negative space. Information density is the brand — list rows, code lines, repository headers, and notification cards are all packed close together so a power user can scan a hundred items without scrolling.
The signature accents are the **Primer blue** (`#0969da`) for links and primary actions, and **GitHub green** (`#1a7f37`) for merged states, success, and the merge button itself. Both feel slightly muted compared to consumer-product blues and greens — saturated enough to read against the dense gray text, restrained enough to disappear into the background when several appear in one viewport.
Typography uses the **system-ui** stack across the entire product so text renders crisply on every OS, paired with **SFMono / Menlo / Consolas** for code. There is no editorial display font; GitHub's voice is the voice of the system you're already on.
**Key Characteristics:**
- True white canvas (`#ffffff`) or deep navy-black (`#0d1117`) — no warmth, no tint
- Hairline gray borders (`#d0d7de`) define every pane and panel
- Primer blue (`#0969da`) for links/primary; GitHub green (`#1a7f37`) for success/merge
- system-ui for prose; SFMono for code — no custom typeface
- Dense list rows with minimal padding; whitespace is rare
- Octicon iconography at 16px / 24px — single-stroke, geometric, consistent
- Pill-shaped status badges with strong color semantics
## 2. Color Palette & Roles
### Primary
- **Canvas Default** (`#ffffff`): Primary page background, light theme.
- **Canvas Subtle** (`#f6f8fa`): Secondary surface, sidebar, input background, header strip.
- **Canvas Inset** (`#eaeef2`): Code block background, deep-inset surface.
- **Fg Default** (`#1f2328`): Primary text, headlines, ink.
- **Fg Muted** (`#656d76`): Secondary text, captions, file paths.
### Brand Accent
- **Primer Blue** (`#0969da`): Links, primary CTAs, focus ring base — the universal interactive color.
- **Primer Blue Hover** (`#0550ae`): Hover/pressed for primary blue.
- **Accent Subtle** (`#ddf4ff`): Soft blue surface for callouts, info banners.
### Semantic
- **Success / Merge Green** (`#1a7f37`): Merged PRs, success badges, merge button.
- **Success Subtle** (`#dafbe1`): Success surface tint.
- **Open Green** (`#1a7f37`): "Open" issue/PR state.
- **Closed / Danger Red** (`#cf222e`): Closed PRs, destructive action, validation error.
- **Danger Subtle** (`#ffebe9`): Error banner surface.
- **Attention / Warning Yellow** (`#9a6700`): Warning text on amber surface.
- **Attention Subtle** (`#fff8c5`): Warning banner surface.
- **Done Purple** (`#8250df`): Merged-and-archived, "done" state, premium badge.
- **Sponsor Pink** (`#bf3989`): Sponsors heart, GitHub sponsors brand.
### Border & Divider
- **Border Default** (`#d0d7de`): Standard hairline border, panel outline.
- **Border Muted** (`#d8dee4`): Inner dividers within a panel.
- **Border Subtle** (`#eaeef2`): Faint table row dividers.
### Dark Theme
- **Dark Canvas** (`#0d1117`): Dark page background.
- **Dark Surface** (`#161b22`): Sidebar, header, secondary surface.
- **Dark Border** (`#30363d`): Standard dark-mode border.
- **Dark Fg** (`#e6edf3`): Primary text on dark.
## 3. Typography Rules
### Font Family
- **Body / UI**: `-apple-system, BlinkMacSystemFont, "Segoe UI", "Noto Sans", Helvetica, Arial, sans-serif`
- **Code / Mono**: `ui-monospace, SFMono-Regular, "SF Mono", Menlo, Consolas, "Liberation Mono", monospace`
- **Emoji**: `"Apple Color Emoji", "Segoe UI Emoji"`
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display | system-ui | 32px (2rem) | 600 | 1.25 | -0.01em | Repo header, marketing hero |
| H1 | system-ui | 24px (1.5rem) | 600 | 1.25 | normal | Page heading |
| H2 | system-ui | 20px (1.25rem) | 600 | 1.25 | normal | Section heading |
| H3 | system-ui | 16px (1rem) | 600 | 1.25 | normal | Sub-section, panel header |
| Body | system-ui | 14px (0.875rem) | 400 | 1.5 | normal | Default text size — not 16px |
| Body Small | system-ui | 12px (0.75rem) | 400 | 1.4 | normal | Captions, file metadata |
| Code | SFMono | 12px (0.75rem) | 400 | 1.45 | normal | Code blocks, diff |
| Code Inline | SFMono | 0.85em | 400 | inherit | normal | Inline `code` spans |
### Principles
- **14px body, not 16px**: GitHub's prose density is its identity. The product reads at 14px to fit more rows in a viewport.
- **Weight binary**: 400 for everything by default; 600 for headlines and emphasis. No 500, no 700.
- **System fonts always**: never load a webfont for chrome — text must render instantly on slow connections.
## 4. Component Stylings

HashiCorp's website is enterprise infrastructure made tangible — a design system that must communicate the complexity of cloud infrastructure management while remaining approachable. The visual language splits between two modes: a clean white light-mode for informational sections and a dramatic dark-mode (`#15181e`, `#0d0e12`) for hero areas and product showcases, creating a day/night duality that mirrors the "build in light, deploy in dark" developer workflow.
The typography is anchored by a custom brand font (HashiCorp Sans, loaded as `__hashicorpSans_96f0ca`) that carries substantial weight — literally. Headings use 600–700 weights with tight line-heights (1.17–1.19), creating dense, authoritative text blocks that communicate enterprise confidence. The hero headline at 82px weight 600 with OpenType `"kern"` enabled is not decorative — it's infrastructure-grade typography.
What distinguishes HashiCorp is its multi-product color system. Each product in the portfolio has its own brand color — Terraform purple (`#7b42bc`), Vault yellow (`#ffcf25`), Waypoint teal (`#14c6cb`), Vagrant blue (`#1868f2`) — and these colors appear throughout as accent tokens via a CSS custom property system (`--mds-color-*`). This creates a design system within a design system: the parent brand is black-and-white with blue accents, while each child product injects its own chromatic identity.
The component system uses the `mds` (Markdown Design System) prefix, indicating a systematic, token-driven approach where colors, spacing, and states are all managed through CSS variables. Shadows are remarkably subtle — dual-layer micro-shadows using `rgba(97, 104, 117, 0.05)` that are nearly invisible but provide just enough depth to separate interactive surfaces from the background.
**Key Characteristics:**
- Dual-mode: clean white sections + dramatic dark (`#15181e`) hero/product areas
- Custom HashiCorp Sans font with 600–700 weights and `"kern"` feature
- Multi-product color system via `--mds-color-*` CSS custom properties
- Product brand colors: Terraform purple, Vault yellow, Waypoint teal, Vagrant blue
- Uppercase letter-spaced captions (13px, weight 600, 1.3px letter-spacing)
- Micro-shadows: dual-layer at 0.05 opacity — depth through whisper, not shout
- Token-driven `mds` component system with semantic variable names
- Tight border radius: 2px–8px, nothing pill-shaped or circular
- System-ui fallback stack for secondary text

### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display Hero | HashiCorp Sans | 82px (5.13rem) | 600 | 1.17 (tight) | normal | `"kern"` enabled |
| Section Heading | HashiCorp Sans | 52px (3.25rem) | 600 | 1.19 (tight) | normal | `"kern"` enabled |
| Feature Heading | HashiCorp Sans | 42px (2.63rem) | 700 | 1.19 (tight) | -0.42px | Negative tracking |
| Sub-heading | HashiCorp Sans | 34px (2.13rem) | 600–700 | 1.18 (tight) | normal | Feature blocks |
| Card Title | HashiCorp Sans | 26px (1.63rem) | 700 | 1.19 (tight) | normal | Card and panel headings |
| Small Title | HashiCorp Sans | 19px (1.19rem) | 700 | 1.21 (tight) | normal | Compact headings |
| Body Emphasis | HashiCorp Sans | 17px (1.06rem) | 600–700 | 1.18–1.35 | normal | Bold body text |
| Body Large | system-ui | 20px (1.25rem) | 400–600 | 1.50 | normal | Hero descriptions |
| Body | system-ui | 16px (1.00rem) | 400–500 | 1.63–1.69 (relaxed) | normal | Standard body text |
| Nav Link | system-ui | 15px (0.94rem) | 500 | 1.60 (relaxed) | normal | Navigation items |
| Small Body | system-ui | 14px (0.88rem) | 400–500 | 1.29–1.71 | normal | Secondary content |
| Caption | system-ui | 13px (0.81rem) | 400–500 | 1.23–1.69 | normal | Metadata, footer links |
| Uppercase Label | HashiCorp Sans | 13px (0.81rem) | 600 | 1.69 (relaxed) | 1.3px | `text-transform: uppercase` |
### Principles
- **Brand/System split**: HashiCorp Sans for headings and brand-critical text; system-ui for body, navigation, and functional text. The brand font carries the weight, system-ui carries the words.
- **Kern always on**: All HashiCorp Sans text enables OpenType `"kern"` — letterfitting is non-negotiable.
- **Tight headings**: Every heading uses 1.17–1.21 line-height, creating dense, stacked text blocks that feel infrastructural — solid, load-bearing.
- **Relaxed body**: Body text uses 1.50–1.69 line-height (notably generous), creating comfortable reading rhythm beneath the dense headings.
- **Uppercase labels as wayfinding**: 13px uppercase with 1.3px letter-spacing serves as the systematic category/section marker — always HashiCorp Sans weight 600.

- HashiCorp logo left-aligned
- system-ui 15px weight 500 for links
- Product categories organized by lifecycle management group
- "Get started" and "Contact us" CTAs in header
- Dark mode variant for hero sections
## 5. Layout Principles
### Spacing System
- Base unit: 8px
- Scale: 2px, 3px, 4px, 6px, 7px, 8px, 9px, 11px, 12px, 16px, 20px, 24px, 32px, 40px, 48px
### Grid & Container
- Max content width: ~1150px (xl breakpoint)
- Full-width dark hero sections with contained content
- Card grids: 2–3 column layouts
- Generous horizontal padding at desktop scale
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile Small | <375px | Tight single column |
| Mobile | 375–480px | Standard mobile |
| Small Tablet | 480–600px | Minor adjustments |
| Tablet | 600–768px | 2-column grids begin |
| Small Desktop | 768–992px | Full nav visible |
| Desktop | 992–1120px | Standard layout |
| Large Desktop | 1120–1440px | Max-width content |
| Ultra-wide | >1440px | Centered, generous margins |
### Whitespace Philosophy
- **Enterprise breathing room**: Generous vertical spacing between sections (48px–80px+) communicates stability and seriousness.
- **Dense headings, spacious body**: Tight line-height headings sit above relaxed body text, creating visual "weight at the top" of each section.
- **Dark as canvas**: Dark hero sections use extra vertical padding to let 3D illustrations and gradients breathe.
### Border Radius Scale
- Minimal (2px): Links, small inline elements
- Subtle (3px): Checkboxes, small inputs
- Standard (4px): Secondary buttons
- Comfortable (5px): Primary buttons, badges, inputs
- Card (8px): Cards, containers, images
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Default surfaces, text blocks |
| Whisper (Level 1) | `rgba(97, 104, 117, 0.05) 0px 1px 1px, rgba(97, 104, 117, 0.05) 0px 2px 2px` | Cards, buttons, interactive surfaces |
| Focus (Level 2) | `3px solid var(--mds-color-focus-action-external)` outline | Focus rings — color-matched to context |
**Shadow Philosophy**: HashiCorp uses arguably the subtlest shadow system in modern web design. The dual-layer shadows at 5% opacity are nearly invisible — they exist not to create visual depth but to signal interactivity. If you can see the shadow, it's too strong. This restraint communicates the enterprise value of stability — nothing floats, nothing is uncertain.
## 7. Do's and Don'ts
### Do
- Use HashiCorp Sans for headings and brand text, system-ui for body and UI text
- Enable `"kern"` on all HashiCorp Sans text
- Use product brand colors ONLY for their respective products (Terraform = purple, Vault = yellow, etc.)
- Apply uppercase labels at 13px weight 600 with 1.3px letter-spacing for section markers
- Keep shadows at the "whisper" level (0.05 opacity dual-layer)
- Use the `--mds-color-*` token system for consistent color application
- Maintain the tight-heading / relaxed-body rhythm (1.17–1.21 vs 1.50–1.69 line-heights)
- Use `3px solid` focus outlines for accessibility
### Don't
- Don't use product brand colors outside their product context (no Terraform purple on Vault content)
- Don't increase shadow opacity above 0.1 — the whisper level is intentional
- Don't use pill-shaped buttons (>8px radius) — the sharp, minimal radius is structural
- Don't skip the `"kern"` feature on headings — the font requires it
- Don't use HashiCorp Sans for small body text — it's designed for 17px+ heading use
- Don't mix product colors in the same component — each product has one color
- Don't use pure black (`#000000`) for dark backgrounds — use `#15181e` or `#0d0e12`
- Don't forget the asymmetric button padding — 9px 9px 9px 15px is intentional
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | <768px | Single column, hamburger nav, stacked CTAs |
| Tablet | 768–992px | 2-column grids, nav begins expanding |
| Desktop | 992–1150px | Full layout, mega-menu nav |
| Large | >1150px | Max-width centered, generous margins |
### Collapsing Strategy
- Hero: 82px → 52px → 42px heading sizes
- Navigation: mega-menu → hamburger
- Product cards: 3-column → 2-column → stacked
- Dark sections maintain full-width but compress padding
- Buttons: inline → full-width stacked on mobile
## 9. Agent Prompt Guide
### Quick Color Reference
- Light bg: `#ffffff`, `#f1f2f3`
- Dark bg: `#15181e`, `#0d0e12`
- Text light: `#000000`, `#3b3d45`
- Text dark: `#efeff1`, `#d5d7db`
- Links: `#2264d6` (light), `#1060ff` (dark), `#2b89ff` (active)
- Helper text: `#656a76`
- Borders: `rgba(178, 182, 189, 0.4)`, `rgb(97, 104, 117)`
- Focus: `3px solid` product-appropriate color
### Example Component Prompts
- "Create a hero on dark background (#15181e). Headline at 82px HashiCorp Sans weight 600, line-height 1.17, kern enabled, white text. Sub-text at 20px system-ui weight 400, line-height 1.50, #d5d7db text. Two buttons: primary dark (#15181e, 5px radius, 9px 15px padding) and secondary white (#ffffff, 4px radius, 8px 12px padding)."
- "Design a product card: white background, 8px radius, dual-layer shadow at rgba(97,104,117,0.05). Title at 26px HashiCorp Sans weight 700, body at 16px system-ui weight 400 line-height 1.63."
- "Build an uppercase section label: 13px HashiCorp Sans weight 600, line-height 1.69, letter-spacing 1.3px, text-transform uppercase, #656a76 color."
- "Create a product-specific CTA button: Terraform → #7b42bc background, Vault → #ffcf25 with dark text, Waypoint → #14c6cb. All: 5px radius, 500 weight text, 16px system-ui."
- "Design a dark form: #0d0e12 input background, #efeff1 text, 1px solid rgb(97,104,117) border, 5px radius, 11px padding. Focus: 3px solid accent-color outline."
### Iteration Guide
1. Always start with the mode decision: light (white) for informational, dark (#15181e) for hero/product
2. HashiCorp Sans for headings only (17px+), system-ui for everything else
3. Shadows are at whisper level (0.05 opacity) — if visible, reduce
4. Product colors are sacred — each product owns exactly one color
5. Focus rings are always 3px solid, color-matched to product context
6. Uppercase labels are the systematic wayfinding pattern — 13px, 600, 1.3px tracking

# Design System Inspired by Hugging Face
> Category: AI & LLM
> ML community hub. Sunny yellow accent, monospace identity, cheerful and dense.
## 1. Visual Theme & Atmosphere
Hugging Face is the rare ML brand that refuses to look serious. The hub leans into a sunshine-yellow accent (`#ffd21e`), a cartoon hugging-face emoji as the logo, and a confident **IBM Plex Mono** voice that reads more like a community zine than a research lab. The page background is a clean off-white (`#fafafa`) with text in a deep slate (`#0d1117`), and the yellow appears in pull quotes, tags, "new" badges, and the model-card header strip — never as an entire surface, always as punctuation.
The typographic system is monospace-forward in a way few product brands attempt: **IBM Plex Mono** for headings and tags, **Source Sans Pro** (or Inter) for body. The mix gives every page a "config file is the README" vibe — fitting for a platform built around `.gitattributes` and `model-card.md`.
Shapes are crisp, not soft: 4–6px radii, 1px solid borders that announce themselves rather than hide. Tables are dense, with row hover in a faint gray (`#f3f4f6`). The brand emoji punctuates everything — chips, headings, even error states wear a 🤗 — so the system feels human even when displaying technical data.
**Key Characteristics:**
- Sunshine yellow `#ffd21e` as the lone saturated accent
- IBM Plex Mono for headings and tags; Source Sans Pro for body
- Off-white canvas (`#fafafa`) with crisp 1px borders (`#e5e7eb`)
- 4–6px radii — closer to brutalist than rounded
- Hugging-face emoji 🤗 used unironically as a system glyph
- Dense tables, minimal padding — a community hub for power users
- Color-coded model categories (NLP blue, vision green, audio purple)
## 2. Color Palette & Roles
### Primary
- **HF Yellow** (`#ffd21e`): Brand primary, badges, "new" pill, model-card header bar.
- **HF Yellow Deep** (`#f59e0b`): Hover/active for yellow.
- **HF Yellow Soft** (`#fff4cc`): Surface tint, callout background.
### Surface & Background
- **Canvas** (`#ffffff`): Primary page background.
- **Canvas Subtle** (`#fafafa`): Alternate section background, footer.
- **Canvas Inset** (`#f3f4f6`): Code block background, hover row.
- **Canvas Dark** (`#0d1117`): Dark theme background.
### Ink & Text
- **Ink Primary** (`#0d1117`): Primary text, headings.
- **Ink Secondary** (`#374151`): Body prose.
- **Ink Muted** (`#6b7280`): Captions, file paths, model authors.
- **Ink Inverse** (`#f9fafb`): Text on dark surface.
### Category Accents (Model Tasks)
- **NLP Blue** (`#2563eb`): Text/NLP task badges.
- **Vision Green** (`#16a34a`): Computer-vision task badges.
- **Audio Purple** (`#9333ea`): Audio/speech task badges.
- **Multimodal Pink** (`#db2777`): Multimodal/diffusion task badges.
- **Tabular Orange** (`#ea580c`): Tabular/structured task badges.
### Semantic
- **Success** (`#16a34a`): Build succeeded, deploy live.
- **Warning** (`#f59e0b`): Slow inference, rate limit.
- **Error** (`#dc2626`): Failed build, broken model.
- **Info** (`#2563eb`): Notice banner.
### Border
- **Border Default** (`#e5e7eb`): Standard 1px hairline.
- **Border Strong** (`#d1d5db`): Emphasized border on hover.
- **Border Subtle** (`#f3f4f6`): Inner divider.
## 3. Typography Rules
### Font Family
- **Display / UI / Headings / Tags**: `IBM Plex Mono`, with fallback: `ui-monospace, SFMono-Regular, Menlo, Consolas, monospace`
- **Body / Prose**: `Source Sans Pro`, with fallback: `Inter, system-ui, -apple-system, sans-serif`
- **Editorial (rare, blog only)**: `Source Serif Pro`, with fallback: `Georgia, serif`
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display | IBM Plex Mono | 48px (3rem) | 600 | 1.1 | -0.01em | Marketing hero |
| H1 | IBM Plex Mono | 32px (2rem) | 600 | 1.2 | normal | Page heading, model name |
| H2 | IBM Plex Mono | 24px (1.5rem) | 600 | 1.25 | normal | Section heading |
| H3 | IBM Plex Mono | 18px (1.125rem) | 600 | 1.3 | normal | Sub-section |
| Body Large | Source Sans Pro | 18px (1.125rem) | 400 | 1.6 | normal | Lede, blog intro |
| Body | Source Sans Pro | 15px (0.9375rem) | 400 | 1.55 | normal | Standard prose, model card |
| Caption | Source Sans Pro | 13px (0.8125rem) | 500 | 1.4 | 0.01em | Author byline, timestamp |
| Tag / Badge | IBM Plex Mono | 12px (0.75rem) | 500 | 1.2 | 0.02em | Task tags, framework chips |
| Code | IBM Plex Mono | 14px (0.875rem) | 400 | 1.55 | normal | Code blocks, inline `model_id` |
### Principles
- **Mono everywhere it matters**: nav links, headings, tags, and metadata are all monospaced. Sans is reserved for paragraphs of prose.
- **Weight under 600**: 600 is the cap; 700 is too loud against yellow. Hierarchy is size and color.
- **Tags read as code**: model tags use mono so they look like the strings developers will paste into Python.

# Design System Inspired by IBM
> Category: Media & Consumer
> Enterprise technology. Carbon design system, structured blue palette.
## 1. Visual Theme & Atmosphere
IBM's website is the digital embodiment of enterprise authority built on the Carbon Design System — a design language so methodically structured it reads like an engineering specification rendered as a webpage. The page operates on a stark duality: a bright white (`#ffffff`) canvas with near-black (`#161616`) text, punctuated by a single, unwavering accent — IBM Blue 60 (`#0f62fe`). This isn't playful tech-startup minimalism; it's corporate precision distilled into pixels. Every element exists within Carbon's rigid 2x grid, every color maps to a semantic token, every spacing value snaps to the 8px base unit.
The IBM Plex type family is the system's backbone. IBM Plex Sans at light weight (300) for display headlines creates an unexpectedly airy, almost delicate quality at large sizes — a deliberate counterpoint to IBM's corporate gravity. At body sizes, regular weight (400) with 0.16px letter-spacing on 14px captions introduces the meticulous micro-tracking that makes Carbon text feel engineered rather than designed. IBM Plex Mono serves code, data, and technical labels, completing the family trinity alongside the rarely-surfaced IBM Plex Serif.
What defines IBM's visual identity beyond monochrome-plus-blue is the reliance on Carbon's component token system. Every interactive state maps to a CSS custom property prefixed with `--cds-` (Carbon Design System). Buttons don't have hardcoded colors; they reference `--cds-button-primary`, `--cds-button-primary-hover`, `--cds-button-primary-active`. This tokenized architecture means the entire visual layer is a thin skin over a deeply systematic foundation — the design equivalent of a well-typed API.
**Key Characteristics:**
- IBM Plex Sans at weight 300 (Light) for display — corporate gravitas through typographic restraint
- IBM Plex Mono for code and technical content with consistent 0.16px letter-spacing at small sizes
- Single accent color: IBM Blue 60 (`#0f62fe`) — every interactive element, every CTA, every link
- Carbon token system (`--cds-*`) driving all semantic colors, enabling theme-switching at the variable level
- 8px spacing grid with strict adherence — no arbitrary values, everything aligns
- Flat, borderless cards on `#f4f4f4` Gray 10 surface — depth through background-color layering, not shadows
- Bottom-border inputs (not boxed) — the signature Carbon form pattern
- 0px border-radius on primary buttons — unapologetically rectangular, no softening

### Principles
- **Light weight at display sizes**: Carbon's expressive type set uses weight 300 (Light) at 42px+. This creates a distinctive tension — the content speaks with corporate authority while the letterforms whisper with typographic lightness.
- **Micro-tracking at small sizes**: 0.16px letter-spacing at 14px and 0.32px at 12px. These seemingly negligible values are Carbon's secret weapon for readability at compact sizes — they open up the tight IBM Plex letterforms just enough.
- **Three functional weights**: 300 (display/expressive), 400 (body/reading), 600 (emphasis/UI labels). Weight 700 is intentionally absent from the production type scale.
- **Productive vs. Expressive**: Productive sets use tighter line-heights (1.29) for dense UI. Expressive sets breathe more (1.40-1.50) for marketing and editorial content.

## 5. Layout Principles
### Spacing System
- Base unit: 8px (Carbon 2x grid)
- Component spacing scale: 2px, 4px, 8px, 12px, 16px, 24px, 32px, 40px, 48px
- Layout spacing scale: 16px, 24px, 32px, 48px, 64px, 80px, 96px, 160px
- Mini unit: 8px (smallest usable spacing)
- Padding within components: typically 16px
- Gap between cards/tiles: 1px (hairline) or 16px (standard)
### Grid & Container
- 16-column grid (Carbon's 2x grid system)
- Max content width: 1584px (max breakpoint)
- Column gutters: 32px (16px on mobile)
- Margin: 16px (mobile), 32px (tablet+)
- Content typically spans 8-12 columns for readable line lengths
- Full-bleed sections alternate with contained content
### Whitespace Philosophy
- **Functional density**: Carbon favors productive density over expansive whitespace. Sections are tightly packed compared to consumer design systems — this reflects IBM's enterprise DNA.
- **Background-color zoning**: Instead of massive padding between sections, IBM uses alternating background colors (white → gray 10 → white) to create visual separation with minimal vertical space.
- **Consistent 48px rhythm**: Major section transitions use 48px vertical spacing. Hero sections may use 80px–96px.
### Border Radius Scale
- **0px**: Primary buttons, inputs, tiles, cards — the dominant treatment. Carbon is fundamentally rectangular.
- **2px**: Occasionally on small interactive elements (tags)
- **24px**: Tags/labels (pill shape — the sole rounded exception)
- **50%**: Avatar circles, icon containers
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow, `#ffffff` background | Default page surface |
| Layer 01 | No shadow, `#f4f4f4` background | Cards, tiles, alternating sections |
| Layer 02 | No shadow, `#e0e0e0` background | Elevated panels within Layer 01 |
| Raised | `0 2px 6px rgba(0,0,0,0.3)` | Dropdowns, tooltips, overflow menus |
| Overlay | `0 2px 6px rgba(0,0,0,0.3)` + dark scrim | Modal dialogs, side panels |
| Focus | `2px solid #0f62fe` inset + `1px solid #ffffff` | Keyboard focus ring |
| Bottom-border | `2px solid #161616` on bottom edge | Active input, active tab indicator |
**Shadow Philosophy**: Carbon is deliberately shadow-averse. IBM achieves depth primarily through background-color layering — stacking surfaces of progressively darker grays rather than adding box-shadows. This creates a flat, print-inspired aesthetic where hierarchy is communicated through color value, not simulated light. Shadows are reserved exclusively for floating elements (dropdowns, tooltips, modals) where the element genuinely overlaps content. This restraint gives the rare shadow meaningful impact — when something floats in Carbon, it matters.
## 7. Do's and Don'ts
### Do
- Use IBM Plex Sans at weight 300 for display sizes (42px+) — the lightness is intentional
- Apply 0.16px letter-spacing on 14px body text and 0.32px on 12px captions
- Use 0px border-radius on buttons, inputs, cards, and tiles — rectangles are the system
- Reference `--cds-*` token names when implementing (e.g., `--cds-button-primary`, `--cds-text-primary`)
- Use background-color layering (white → gray 10 → gray 20) for depth instead of shadows
- Use bottom-border (not box) for input field indicators
- Maintain the 48px default button height and asymmetric padding for icon accommodation
- Apply Blue 60 (`#0f62fe`) as the sole accent — one blue to rule them all
### Don't
- Don't round button corners — 0px radius is the Carbon identity
- Don't use shadows on cards or tiles — flatness is the point
- Don't introduce additional accent colors — IBM's system is monochromatic + blue
- Don't use weight 700 (Bold) — the scale stops at 600 (Semibold)
- Don't add letter-spacing to display-size text — tracking is only for 14px and below
- Don't box inputs with full borders — Carbon inputs use bottom-border only
- Don't use gradient backgrounds — IBM's surfaces are flat, solid colors
- Don't deviate from the 8px spacing grid — every value should be divisible by 8 (with 2px and 4px for micro-adjustments)
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Small (sm) | 320px | Single column, hamburger nav, 16px margins |
| Medium (md) | 672px | 2-column grids begin, expanded content |
| Large (lg) | 1056px | Full navigation visible, 3-4 column grids |
| X-Large (xlg) | 1312px | Maximum content density, wide layouts |
| Max | 1584px | Maximum content width, centered with margins |
### Touch Targets
- Button height: 48px default, minimum 40px (compact)
- Navigation links: 48px row height for touch
- Input height: 40px default, 48px large
- Icon buttons: 48px square touch target
- Mobile menu items: full-width 48px rows
### Collapsing Strategy
- Hero: 60px display → 42px → 32px heading as viewport narrows
- Navigation: full horizontal masthead → hamburger with slide-out panel
- Grid: 4-column → 2-column → single column
- Tiles/cards: horizontal grid → vertical stack
- Images: maintain aspect ratio, max-width 100%
- Footer: multi-column link groups → stacked single column
- Section padding: 48px → 32px → 16px
### Image Behavior
- Responsive images with `max-width: 100%`
- Product illustrations scale proportionally
- Hero images may shift from side-by-side to stacked below
- Data visualizations maintain aspect ratio with horizontal scroll on mobile

- "Build a tag component: Blue 10 (#edf5ff) background, Blue 60 (#0f62fe) text, 4px 8px padding, 24px border-radius, 12px IBM Plex Sans weight 400."
### Iteration Guide
1. Always use 0px border-radius on buttons, inputs, and cards — this is non-negotiable in Carbon
2. Letter-spacing only at small sizes: 0.16px at 14px, 0.32px at 12px — never on display text
3. Three weights: 300 (display), 400 (body), 600 (emphasis) — no bold
4. Blue 60 is the only accent color — do not introduce secondary accent hues
5. Depth comes from background-color layering (white → #f4f4f4 → #e0e0e0), not shadows
6. Inputs have bottom-border only, never fully boxed
7. Use `--cds-` prefix for token naming to stay Carbon-compatible
8. 48px is the universal interactive element height

# Design System Inspired by Intercom
> Category: Productivity & SaaS
> Customer messaging. Friendly blue palette, conversational UI patterns.
## 1. Visual Theme & Atmosphere
Intercom's website is a warm, confident customer service platform that communicates "AI-first helpdesk" through a clean, editorial design language. The page operates on a warm off-white canvas (`#faf9f6`) with off-black (`#111111`) text, creating an intimate, magazine-like reading experience. The signature Fin Orange (`#ff5600`) — named after Intercom's AI agent — serves as the singular vibrant accent against the warm neutral palette.
The typography uses Saans — a custom geometric sans-serif with aggressive negative letter-spacing (-2.4px at 80px, -0.48px at 24px) and a consistent 1.00 line-height across all heading sizes. This creates ultra-compressed, billboard-like headlines that feel engineered and precise. Serrif provides the serif companion for editorial moments, and SaansMono handles code and uppercase technical labels. MediumLL and LLMedium appear for specific UI contexts, creating a rich five-font ecosystem.
What distinguishes Intercom is its remarkably sharp geometry — 4px border-radius on buttons creates near-rectangular interactive elements that feel industrial and precise, contrasting with the warm surface colors. Button hover states use `scale(1.1)` expansion, creating a physical "growing" interaction. The border system uses warm oat tones (`#dedbd6`) and oklab-based opacity values for sophisticated color management.
**Key Characteristics:**
- Warm off-white canvas (`#faf9f6`) with oat-toned borders (`#dedbd6`)
- Saans font with extreme negative tracking (-2.4px at 80px) and 1.00 line-height
- Fin Orange (`#ff5600`) as singular brand accent
- Sharp 4px border-radius — near-rectangular buttons and elements
- Scale(1.1) hover with scale(0.85) active — physical button interaction
- SaansMono uppercase labels with wide tracking (0.6px–1.2px)
- Rich multi-color report palette (blue, green, red, pink, lime, orange)
- oklab color values for sophisticated opacity management

# Design System Inspired by kami (紙 / 纸)
> Category: Editorial & Print
> Editorial paper system: warm parchment canvas, ink-blue accent, serif-led hierarchy. Built for resumes, one-pagers, white papers, portfolios, slide decks — anything that should feel like high-quality print rather than UI. Multilingual by design (EN · zh-CN · ja).
## 1. Visual Theme & Atmosphere
kami compresses into one sentence: **warm parchment canvas, ink-blue accent, serif carries hierarchy, no cool grays, no hard shadows.** It is not a UI framework — it is a constraint system for the page, designed to keep deliverables stable, clear, and unmistakably *printed*. The name reads as **kami / 紙 / 纸** — the same word for "paper" across Japanese and Chinese — and the system is co-designed across English, Simplified Chinese, and Japanese typesetting from the ground up, not retrofitted.
The page background is parchment (`#f5f4ed`), never pure white. Text sits on cream. The single chromatic move is ink-blue (`#1B365D`) — used on section numbers, primary CTAs, the left rule of a quote, the W500 weight in a metric. Everything else is a warm neutral with a yellow-brown undertone; cool blue-grays are absent on purpose.
Hierarchy is carried almost entirely by **serif type at a single weight (500)**. There is no bold, no italic, no second accent color. Density is achieved through tight line-heights (1.10–1.55), four-level gray ramps, and ring/whisper shadows that act as halos rather than drops. The aesthetic borrows from editorial print, technical white papers, and old typewritten correspondence — the goal is "good content on good paper," not "modern app UI."
**Key Characteristics:**
- Warm parchment canvas (`#f5f4ed`) — never `#ffffff`
- Single accent: ink-blue (`#1B365D`), covers ≤ 5% of any surface
- All grays warm (R ≈ G > B), no cool blue-grays anywhere
- Serif everywhere for hierarchy: Charter (EN), TsangerJinKai02 / Source Han Serif (CN), YuMincho (JA)
- Locked at weight 500 — no synthetic bold (700/900) and **no italic**
- Tight print rhythm (line-heights 1.10–1.55), much denser than typical web body
- Depth via 1px rings and whisper shadows (`0 4px 24px rgba(0,0,0,0.05)`), never hard drop shadows
- Tag fills are solid hex (e.g. `#E4ECF5`), never `rgba()` — print renderers double-paint alpha tags
- Numbers sit in `font-variant-numeric: tabular-nums` so columns of metrics don't shimmy
## 2. Color Palette & Roles
### Brand
- **Ink Blue** (`#1B365D`): The only chromatic color. CTAs, section numbers, link text on light surfaces, the left rule on a section title or quote, the active state of a switcher, the W500 metric value.
- **Ink Light** (`#2D5A8A`): Brighter variant, only for links sitting on dark surfaces.
> Rule: ink-blue covers ≤ **5% of document surface area**. More than that turns into ornament and the restraint collapses.
### Surface
- **Parchment** (`#f5f4ed`): The page background — warm cream, the emotional foundation. Never replace with white.
- **Ivory** (`#faf9f5`): Cards and lifted containers. Sits one half-shade brighter than parchment.
- **Warm Sand** (`#e8e6dc`): Default button background, secondary interactive surfaces.
- **Dark Surface** (`#30302e`): Dark-theme containers — warm charcoal, not slate.
- **Deep Dark** (`#141413`): Dark-theme page background. Olive-tinted near-black, never `#000000`.
### Text (four levels — no fifth)
- **Near Black** (`#141413`): Primary text. Slight olive warmth, gentler than pure black.
- **Dark Warm** (`#3d3d3a`): Secondary text, table headers, link defaults.
- **Olive** (`#504e49`): Subtext, captions, descriptions. (JA override: `#4d4c48` because YuMincho strokes are thinner.)
- **Stone** (`#6b6a64`): Tertiary — dates, metadata, meta labels.
### Border
- **Border** (`#e8e6dc`): Primary border — section dividers, card edges, table headers.
- **Border Soft** (`#e5e3d8`): Row separators, inner dividers, subtle internal lines.
### Tag tints (solid, NOT rgba)
Print renderers (WeasyPrint and friends) double-paint alpha fills, leaving a visible "double rectangle" on zoom. Tag and chip backgrounds must be solid hex, pre-blended over parchment:
| Effective alpha of `#1B365D` over parchment | Solid hex |
|---|---|
| 0.08 | `#EEF2F7` |
| 0.14 | `#E4ECF5` |
| **0.18 (default tag)** | **`#E4ECF5`** |
| 0.22 | `#D0DCE9` |
| 0.30 | `#D6E1EE` |
### Gradient System
kami is **gradient-free** by default. The only sanctioned gradient is the soft tag brush running `#D6E1EE → #E4ECF5 → #EEF2F7` left-to-right at very low contrast — used at most once per page on a single decorative tag. Do not introduce hero gradients, brand-color washes, or backdrop-filter blurs.
### Forbidden colors
- `#ffffff` as a page background
- `#000000` anywhere
- Any cool-gray surface (`#f8f9fa`, `#f3f4f6`, `slate-*`)
- Any second saturated color (no second accent — pick ink-blue or pick nothing)
## 3. Typography Rules
### Font Stacks
```css
/* English (default) */
--serif: Charter, Georgia, Palatino, "Times New Roman", serif;
/* Chinese */
--serif: "TsangerJinKai02", "Source Han Serif SC", "Noto Serif CJK SC",
"Songti SC", "STSong", Georgia, serif;
/* Japanese */
--serif: "YuMincho", "Yu Mincho", "Hiragino Mincho ProN",
"Noto Serif CJK JP", "Source Han Serif JP",
"TsangerJinKai02", Georgia, serif;
/* Mono — must include CJK fallback so labels/comments don't render as boxes */
--mono: "JetBrains Mono", "SF Mono", "Fira Code", Consolas, Monaco,
"TsangerJinKai02", "Source Han Serif SC", monospace;
/* Sans always equals serif. There is no separate sans-serif family. */
--sans: var(--serif);
```
### When to swap the stack
The three stacks above are **alternative values for `--serif`**, not three families layered together. When generating an artifact, set the primary stack on `:root` based on the dominant language of the content; let the browser's per-glyph fallback resolve mixed-script text inline. Concretely:
- `<html lang="en">` (or English-dominant content) → leave `--serif` on the EN stack. CJK glyphs that appear inline will fall through to the system Han fallback.
- `<html lang="zh-CN">` → override `--serif` to the CN stack on `:root` or on `html[lang="zh-CN"]`. Latin glyphs render via the Georgia tail of the stack.
- `<html lang="ja">` → override `--serif` to the JA stack and apply the `--olive: #4d4c48` text-color override (YuMincho strokes are thinner; the standard olive looks anemic against parchment).
- Multi-language artifacts (e.g. a deck with one Japanese chapter): set the dominant-language stack on `:root`, then scope the override on a wrapper element (`section[lang="ja"] { --serif: …; }`). Do **not** chain all three families inside a single `font-family` — that dilutes the visual character of every page.
### Hierarchy (screen, px)
The hierarchy table below is sized for **screen-rendered web pages** (resume, one-pager, portfolio shown at desktop width). For other surfaces, scale from the print pt baseline using these ratios — the same rules the kami `slides.py` template applies:
| Surface | Macro tokens (font, padding) | Micro tokens (border, radius, tracking) |
|---|---|---|
| Page / web artifact (one-pager, resume, white paper) | print pt × ~1.33 | print pt × 1 |
| Slide / 1920×1080 deck | print pt × ~1.6 | print pt × ~0.6 |
Concretely: a 22pt H1 in print becomes ~29px on a web page and ~36px on a slide; an 8pt letter-spacing value that reads as confident in print drops to ~5px on a slide. Letter-spacing always uses the slide micro ratio — print tracking applied at slide scale falls apart.
| Role | Family | Size | Weight | Line-height | Letter-spacing | Notes |
|------|--------|------|--------|-------------|----------------|-------|
| Hero / Display | serif | 96–106px | 500 | 1.05–1.10 | -1.2px | One per page max — cover or one-pager hero |
| Display CN/JA | serif | 48–64px | 500 | 1.10–1.12 | 0–0.3px | CJK glyphs need looser tracking and smaller absolute size |
| Section title | serif | 28–32px | 500 | 1.20 | 0.4px | Anchors a chapter; preceded by section number |
| H2 | serif | 22px | 500 | 1.25 | 0 | Subsection |
| H3 | serif | 17–18px | 500 | 1.30 | 0 | Item title, card heading |
| Manifesto / pull quote | serif | 20px | 400 | 1.65 | 0.05em | The one place letter-spacing earns its keep |
| Lede | serif | 15–16px | 500 | 1.55 | 0 | Intro paragraph under a section title |
| Body | serif | 14px | 400 | 1.55 | 0 (EN) · 0.35px (CN) · 0.02em (JA) | Reading body |
| Body dense | serif | 13–14px | 400 | 1.40–1.45 | 0 | Resume, one-pager, dense lists |
| Caption | serif | 12px | 500 | 1.45 | 0 | Notes, figure captions |
| Eyebrow / overline | sans | 12px | 500 | 1 | 1.2px, **uppercase** | Section eyebrow, switcher, meta header |
| Label | sans | 12px | 500 | 1.35 | 0.4px, uppercase | Small inline label, ink-blue if active |
| Mono / spec | mono | 12–13px | 400 | 1.55 | 0.4px | Hex codes, type specs, code |
### Weight rules
- Serif uses **only weights 400 and 500**. No 600, no 700, no 900.
- `strong { font-weight: 500 }` is explicitly set so browsers don't synthesize bold.
- Sans labels may use 500 or 600 at small sizes for legibility.
- **No italic anywhere.** No `font-style: italic`. If emphasis is needed, switch the color to ink-blue or wrap in a tag.
### Line-height
- Tight headline: 1.10–1.30 (display, H1, H2)
- Dense body: 1.40–1.45 (resume, one-pager, dense lists)
- Reading body: 1.50–1.55 (long-form chapters, letters)
- Label / caption: 1.30–1.40
Forbidden: 1.6+ (web rhythm, floats off the page) and 1.0–1.05 (lines collide except at giant display sizes).
### Letter-spacing
- EN body: `0`
- CN body (TsangerJinKai02): `0.35px` to compensate for the font's natural density
- JA body: `0.02em`
- All-caps overlines and small labels (< 10pt): +0.5 to +1.2px is mandatory
- Display CJK at 24px+: `0.2–1px` of optical breathing room
- On slides, tracking is roughly **half** of print values — 8px tracking that reads as confident in a printed deck disintegrates at slide scale.
### Tabular-nums contexts
`font-variant-numeric: tabular-nums` is mandatory anywhere kami numbers stack vertically or sit alongside other numbers — uneven proportional digits read as a layout bug at print resolution. Apply it to:
- Metric values (the big ink-blue number in `.metric-value`) and any side-by-side metric row
- Slide footers and slide counters (`02 / 05`), page numbers, deck pagination
- Section numbers in chapter heads (`01`, `02`, …) when they appear in a stacked TOC
- Resume dates, employment ranges, and education years
- Financial figures: revenue, ARR/MRR, valuations, tables of P&L line items
- White-paper and equity-report data tables (every numeric column)
- Stat-dashboard hero numbers and KPI grids
- Changelog version numbers (`1.4.2 → 1.4.3`) and any inline release dates
- Any inline numeric span inside a paragraph that compares values (`from 142 to 168`)
Do **not** apply tabular-nums to running prose where a single number appears mid-sentence — proportional digits read better there. The rule is "stacks and tables, yes; sentences, no."
## 4. Component Stylings
### Cards / Containers
```css
background: var(--ivory); /* never parchment — cards lift one shade */
border: 1px solid var(--border);
border-radius: 8px; /* default; featured cards 12px; hero 16–24px */
padding: 28px 28px 24px; /* component interior */
transition: box-shadow 0.2s;
/* Hover lifts via whisper shadow only — no transform, no brightness shift */
&:hover { box-shadow: 0 4px 24px rgba(0,0,0,0.05); }
```
### Buttons
```css
.btn-primary {
background: var(--brand); /* #1B365D */
color: var(--ivory);
box-shadow: 0 0 0 1px var(--brand); /* ring shadow as edge */
padding: 8px 14px;
border-radius: 8px;
font: 500 12px/1 var(--sans);
letter-spacing: 0.4px;
}
.btn-secondary {
background: var(--warm-sand);
color: var(--dark-warm);
box-shadow: 0 0 0 1px var(--border);
}
.btn-ghost {
background: transparent;
color: var(--brand);
box-shadow: 0 0 0 1px var(--brand);
}
```
### Tags / Chips
```css
.tag {
font: 500 12px/1 var(--sans);
padding: 2px 7px;
border-radius: 2px;
color: var(--brand);
background: #EEF2F7; /* solid hex, NOT rgba */
letter-spacing: 0.4px;
}
.tag.standard { background: #E4ECF5; padding: 2px 8px; border-radius: 4px; }
/* The single sanctioned gradient — see §2 "Gradient System".
* Use at most once per page on a "featured" or "new" tag. The gradient
* runs darkest-to-lightest left-to-right so the eye reads it as a
* watercolor wash, not a button highlight. */
.tag.brush {
background: linear-gradient(to right, #D6E1EE, #E4ECF5 70%, #EEF2F7);
}
```
```html
<!-- Example: a single brush tag flagging the new chapter in a long doc -->
<span class="tag brush">New · Edition 02</span>
```
### Quote
```css
.quote {
border-left: 2px solid var(--brand);
padding: 4px 0 4px 14px;
font: 500 15px/1.55 var(--serif);
color: var(--olive);
}
```
### Section title pattern
```html
<div class="section-head">
<p class="section-num">01</p> <!-- ink-blue, 14px serif, tracking 0.4px -->
<h2 class="section-title">Color</h2> <!-- 32px serif 500 -->
<p class="section-lede">Optional one-line description in olive.</p>
</div>
```
The number is set in the same serif as the title, in ink-blue, the same size as caption text. There is no underline, no left bar, no eyebrow — the number *is* the marker.
### Metrics
```html
<div class="metric">
<div class="metric-value">8.4×</div> <!-- serif 500 24px ink-blue, tabular-nums -->
<div class="metric-label">faster ship</div> <!-- serif 12px olive -->
</div>
```
Numbers always sit in `font-variant-numeric: tabular-nums` so adjacent metrics align.
### Lists
```css
ul.dash {
list-style: none; padding: 0;
}
ul.dash li {
position: relative; padding-left: 14px;
}
ul.dash li::before {
content: "\2013"; /* en-dash, ink-blue */
position: absolute; left: 0;
color: var(--brand);
}
```
Bullets are en-dashes in ink-blue, never filled discs.
### Code block
```css
.code {
background: var(--ivory);
border: 1px solid var(--border);
border-radius: 6px;
padding: 12px 14px;
font: 12px/1.55 var(--mono);
color: var(--near-black);
white-space: pre;
}
.code .k { color: var(--brand); } /* keyword */
.code .c { color: var(--stone); } /* comment */
```
## 5. Layout Principles
### Page geometry (print A4)
| Document | Top | Right | Bottom | Left |
|---|---|---|---|---|
| Resume (dense) | 11mm | 13mm | 11mm | 13mm |
| One-Pager | 15mm | 18mm | 15mm | 18mm |
| Long Doc | 20mm | 22mm | 22mm | 22mm |
| Letter | 25mm | 25mm | 25mm | 25mm |
| Portfolio | 12mm | 15mm | 12mm | 15mm |
Rule: **denser = smaller margins, more formal = larger margins.**
### Web / screen pages
- Max content width: `1120px`, centered, with `padding: 88px 64px 120px` on desktop.
- Section gap: `72px` between top-level sections.
- Card-grid columns: 2 by default at desktop; collapse to 1 below 768px.
- Table columns sized in absolute px (not %), so kami tables don't reflow into spaghetti.
### Slides (1920×1080)
- Four-side padding baseline: `--slide-pad: 80px`.
- Padding-top of a content slide: 72–80px (print is 96–120px; slides are more compact).
- Sizing follows the surface ratios from §3 ("Hierarchy"): macro tokens × 1.6, micro tokens × 0.6 against the print pt baseline.
- Cover and chapter slides may flip background to ink-blue (`#1B365D`) with ivory text; everything else stays on parchment.
## 6. Depth & Elevation
Three sanctioned levels — that is the entire system:
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (0) | No shadow, no border | Body text, manifesto, paragraphs on parchment |
| Ring (1) | `1px solid var(--border)` or `0 0 0 1px var(--brand)` | Cards, primary buttons, table edges |
| Whisper (2) | `0 4px 24px rgba(0,0,0,0.05)` | Hovered cards, lifted hero containers, screenshots |
Forbidden:
- Hard drop shadows (`0 12px 40px rgba(0,0,0,0.25)` and the like) — the page is paper, not a UI panel
- Neumorphism, glassmorphism, backdrop-filter blurs
- Multi-layer composite shadows
### Border radius scale
`2px → 4px → 6px → 8px (default) → 12px → 16px`. Tags hover at 2–4px, buttons and cards at 8px, featured / hero containers at 12–16px. Anything above 16px is reserved for cover-slide visuals.
## 7. Do's and Don'ts
### Do
- Use parchment (`#f5f4ed`) as the page background — the warm cream tone *is* the kami personality.
- Use a single serif weight (500) for every heading; let size carry hierarchy.
- Use ink-blue (`#1B365D`) only for primary CTAs, section numbers, links, the left rule of a quote, and the W500 in metrics.
- Keep every gray warm (yellow-brown undertone). When in doubt, sample with `R ≈ G > B`.
- Use ring shadows or whisper shadows for elevation; never hard drops.
- Set tag backgrounds as solid hex pre-blended over parchment, never `rgba()`.
- Set numbers in `font-variant-numeric: tabular-nums`.
- Pair the section number with the section title in the same serif — no eyebrow needed.
- Default bullets to ink-blue en-dashes (`–`).
### Don't
- Don't use `#ffffff` as page background, anywhere.
- Don't introduce a second accent color or a chromatic gradient.
- Don't use cool blue-grays (`slate-*`, `#f3f4f6`, `#6b7280`). Every neutral is warm.
- Don't use bold (700+) on serif — weight 500 is the ceiling.
- **Don't use italic anywhere.** No `font-style: italic`. Swap to ink-blue or a tag instead.
- Don't use sans-serif for headlines or body — sans is reserved for eyebrows, switchers, and small labels (and the sans stack literally equals the serif stack).
- Don't drop body line-height below 1.4 or push it above 1.55 — that range *is* kami's reading rhythm.
- Don't use round-disc bullets, drop shadows, or pill-shaped chips with heavy borders.
- Don't apply `backdrop-filter`, `mix-blend-mode`, or any modern compositing trick — the system targets print fidelity.
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Phone | < 768px | Single column. Hero 46px, section title 24px, manifesto 17px. Card padding drops to 20px 16px. Hide `.hero-tokens` row. |
| Tablet | 768–979px | Most 2-col grids hold; switch tag tints from 5 to 3 columns. |
| Desktop | ≥ 980px | Full 2-col / 4-col grids, JA gets `white-space: nowrap` rescue rules on long ledes. |
### Touch targets
- Buttons keep `8 14px` padding minimum.
- Tap targets stay above 44×44 by giving cards generous internal padding rather than oversizing chrome.
### Print
- `@page { size: A4; margin: 14mm 16mm; background: #f5f4ed; }`.
- Section, hero, family, comp, swatch, tint, quote, blockquote, pre, tr, anti-pattern blocks all use `break-inside: avoid` so kami pages don't snap mid-card.
- `-webkit-print-color-adjust: exact` is required so the parchment background actually reaches paper.
## 9. Agent Prompt Guide
### Quick Color Reference
- Page Background: "Parchment (#f5f4ed)"
- Card Surface: "Ivory (#faf9f5)"
- Brand / CTA: "Ink Blue (#1B365D)"
- Primary Text: "Near Black (#141413)"
- Secondary Text: "Dark Warm (#3d3d3a)"
- Subtext / Caption: "Olive (#504e49)"
- Tertiary / Meta: "Stone (#6b6a64)"
- Border: "Border (#e8e6dc)"
- Tag fill (default): "#E4ECF5 solid (NOT rgba)"
### Example Component Prompts
- "Build a kami one-pager hero on Parchment (#f5f4ed). Eyebrow row in 12px sans uppercase Stone (#6b6a64), letter-spacing 1.2px. Headline in serif 500 at 96px Near Black (#141413), line-height 1.05, letter-spacing -1.2px. Tagline below in serif 500 at 21px Olive (#504e49)."
- "Design a kami section header. A two-line stack: section number `01` in serif 500 at 14px Ink Blue (#1B365D) tracking 0.4px, then the title in serif 500 at 32px Near Black. Optional lede in serif 500 at 16px Olive."
- "Render a kami metric row of three metrics. Each metric is a vertical pair: value in serif 500 at 24px Ink Blue with `font-variant-numeric: tabular-nums`, label in 12px Olive. Gap between metrics: 28px."
- "Build a kami card on Ivory (#faf9f5) with 1px Border (#e8e6dc), 8px radius, 28px padding. Title in serif 500 at 16px Near Black. Hint underneath in 12px mono Stone. On hover, add a whisper shadow `0 4px 24px rgba(0,0,0,0.05)`. No transform, no color shift."
- "Build a kami slide cover at 1920×1080. Background ink-blue (#1B365D). Centered title in serif 500 at 96px Ivory (#faf9f5). Below, a 1px ivory rule, 96px wide. Author and date below in serif 500 at 18px Ivory at 70% opacity."
### Iteration Guide
1. **Start by checking the gray temperature.** If a gray reads cool, the design is no longer kami. Replace with the warm ramp.
2. **Audit the accent.** If ink-blue covers more than ~5% of the visible surface, reduce — push elements back to Olive or Dark Warm.
3. **Audit weight.** Any weight above 500 on serif is wrong. Replace with weight 500 and let size carry the contrast.
4. **Audit italic.** No italic, ever. Swap to ink-blue color or a small tag.
5. **Audit shadows.** If a shadow is visible at a glance, it's too strong. The only shadows are 1px rings and the `0 4px 24px rgba(0,0,0,0.05)` whisper.
6. **Tag fills must be solid hex.** If you wrote `rgba(27, 54, 93, 0.18)`, replace with `#E4ECF5`.
7. **Numbers tabular-nums.** Any column of numbers without `font-variant-numeric: tabular-nums` will look wrong on a print render.

# Design System Inspired by Kraken
> Category: Fintech & Crypto
> Crypto trading. Purple-accented dark UI, data-dense dashboards.
## 1. Visual Theme & Atmosphere
Kraken's website is a clean, trustworthy crypto exchange that uses purple as its commanding brand color. The design operates on white backgrounds with Kraken Purple (`#7132f5`, `#5741d8`, `#5b1ecf`) creating a distinctive, professional crypto identity. The proprietary Kraken-Brand font handles display headings with bold (700) weight and negative tracking, while Kraken-Product (with IBM Plex Sans fallback) serves as the UI workhorse.
**Key Characteristics:**
- Kraken Purple (`#7132f5`) as primary brand with darker variants (`#5741d8`, `#5b1ecf`)
- Kraken-Brand (display) + Kraken-Product (UI) dual font system
- Near-black (`#101114`) text with cool blue-gray neutral scale
- 12px radius buttons (rounded but not pill)
- Subtle shadows (`rgba(0,0,0,0.03) 0px 4px 24px`) — whisper-level
- Green accent (`#149e61`) for positive/success states
## 2. Color Palette & Roles
### Primary
- **Kraken Purple** (`#7132f5`): Primary CTA, brand accent, links
- **Purple Dark** (`#5741d8`): Button borders, outlined variants

# Design System Inspired by Lamborghini
> Category: Automotive
> Supercar brand. True black surfaces, gold accents, dramatic uppercase typography.
## 1. Visual Theme & Atmosphere
Lamborghini's website is a cathedral of darkness — a digital stage where jet-black surfaces stretch infinitely and every element emerges from the void like a machine under a spotlight. The page is almost entirely black. Not dark gray, not near-black — true, uncompromising black (`#000000`) that saturates the viewport and refuses to yield. Into this abyss, white type and Lamborghini Gold (`#FFC000`) are deployed with surgical precision, creating a visual language that feels like walking through a nighttime motorsport event where every surface absorbs light except the things that matter.
The hero is a full-viewport video — dark, cinematic, immersive — showing event footage or vehicle reveals with the Lamborghini bull logo floating ethereally above. The navigation is minimal: a centered bull logo, a "MENU" hamburger on the left, and search/bookmark icons on the right, all rendered in white against the black canvas. There are no borders, no visible nav containers, no background color on the header — just white marks floating in darkness. The overall mood is nocturnal luxury: exclusive, theatrical, and deliberately intimidating. Each section transition is a scroll through darkness into the next revelation.
Typography is the voice of this darkness. LamboType — a custom Neo-Grotesk typeface created by Character Type and design agency Strichpunkt — is used for everything from 120px uppercase display headlines to 10px micro labels. Its distinctive 12° angled terminals are inspired by the aerodynamic lines of Lamborghini's super sports cars, and its proportions range from Normal to Ultracompressed width. Headlines SHOUT in uppercase at enormous scales with tight line-heights (0.92 at 120px), creating dense blocks of text that feel stamped from steel. The typeface carries hexagonal geometric DNA — constructed from hexagons, three-armed stars, and circles — that echoes throughout the interface in the hexagonal pause button and UI icons. Built on Bootstrap grid with 68 Element Plus/UI components, the technical infrastructure is substantial beneath the theatrical surface.
**Key Characteristics:**
- True black (`#000000`) dominant surfaces with white and gold as the only relief colors
- LamboType custom Neo-Grotesk font with 12° angled terminals inspired by aerodynamic car lines
- Lamborghini Gold (`#FFC000`) as the sole accent color — used exclusively for primary CTA buttons
- All-uppercase display typography at extreme scales (120px, 80px, 54px) with tight line-heights
- Full-viewport video heroes with cinematic event/vehicle content
- Zero border-radius on buttons — sharp, angular, uncompromising rectangles
- Hexagonal motifs in UI elements (pause button, icon system) echoing brand geometry
- Bootstrap grid system + Element Plus/UI 68 components underneath
- Transparent ghost buttons with white borders at 50% opacity as the secondary CTA pattern
## 2. Color Palette & Roles
### Primary
- **Lamborghini Gold** (`#FFC000`): The signature accent color — a warm, saturated amber-gold (rgb 255, 192, 0) used exclusively for primary action buttons ("Discover More", "Tickets", "Start Configuration"). The only chromatic color in the entire interface, it ignites against the black canvas like a headlight cutting through night
- **Pure White** (`#FFFFFF`): Primary text color on dark surfaces, logo rendering, nav elements, and light-mode button fills — the voice that speaks from the darkness
### Secondary & Accent
- **Dark Gold** (`#917300`): Hover/pressed state for gold buttons — a deep amber (rgb 145, 115, 0) that darkens the gold to signal interaction
- **Gold Text** (`#FFCE3E`): Slightly lighter gold variant (rgb 255, 206, 62) used for inline text accents and highlighted labels
- **Cyan Pulse** (`#29ABE2`): Electric blue-cyan (rgb 41, 171, 226) appearing as an informational accent and interactive element highlight
- **Link Blue** (`#3860BE`): Medium blue (rgb 56, 96, 190) used universally for link hover states across all text colors
### Surface & Background
- **Absolute Black** (`#000000`): The dominant surface color — used for page background, hero sections, header, footer, and most containers
- **Charcoal** (`#202020`): Elevated dark surface (rgb 32, 32, 32) — the primary "dark gray" for cards, panels, and text containers sitting above the black canvas
- **Dark Iron** (`#181818`): Subtle surface variant (rgb 24, 24, 24) — barely distinguishable from black, used for footer and deep sections
- **Overlay Black** (`rgba(0,0,0,0.7)`): Semi-transparent overlay for modals and video dimming
- **Near White** (`#F8F8F8`): Rare light surface (rgb 248, 248, 248) for content blocks in white-mode sections
- **Mist** (`#E6E6E6`): Light gray surface for secondary light-mode containers
### Neutrals & Text
- **Pure White** (`#FFFFFF`): Primary text on dark backgrounds — headlines, body, nav labels
- **Smoke** (`#F5F5F5`): Secondary text on dark surfaces — slightly softer than pure white
- **Graphite** (`#494949`): Dark gray text on light surfaces (rgb 73, 73, 73)
- **Ash** (`#7D7D7D`): Mid-range gray for muted text, timestamps, and metadata (rgb 125, 125, 125)
- **Steel** (`#969696`): Lighter gray for disabled text and subtle labels (rgb 150, 150, 150)
- **Slate** (`#666666`): Alternative mid-gray for secondary content
- **Iron** (`#555555`): Dark mid-gray for body text variants
- **Shadow** (`#313131`): Very dark gray for text on dark surfaces where white is too strong
### Semantic & Accent
- **Cyan Pulse** (`#29ABE2`): Used for informational highlights and interactive feedback
- **Link Blue** (`#3860BE`): Universal hover state for all hyperlinks
- **Teal Action** (`#1EAEDB`): Button hover background for transparent/ghost variants (rgb 30, 174, 219)
### Gradient System
- No explicit gradients in the color palette — the dark-to-light progression is achieved through surface layering: `#000000` → `#181818` → `#202020` → `#494949` → `#7D7D7D`
- Video heroes use natural atmospheric gradients from the content itself
- Top-of-page gradient: subtle dark-to-darker fade at the edges of full-bleed imagery
## 3. Typography Rules
### Font Family
- **Display & UI**: `LamboType`, Roboto, Helvetica Neue, Arial — custom Neo-Grotesk typeface by Character Type for Lamborghini's 2024 brand refresh. Available in widths from Normal to Ultracompressed and weights from Light (300) to Black. Features 12° angled terminals inspired by aerodynamic car geometry, hexagonal construction logic, and support for 200+ languages including Latin, Cyrillic, and Greek
- **Fallback/UI**: `Open Sans` — used for some button/form contexts as system fallback
- **No italic variants** observed on the marketing site — the brand voice is always upright
### Hierarchy
| Role | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|--------|-------------|----------------|-------|
| Hero Display | 120px (7.50rem) | 400 | 0.92 | normal | LamboType, uppercase, maximum impact |
| Display 2 | 80px (5.00rem) | 400 | 1.13 | normal | LamboType, uppercase, major section titles |
| Section Title | 54px (3.38rem) | 400 | 1.19 | normal | LamboType, uppercase |
| Sub-section | 40px (2.50rem) | 400 | 1.15 | normal | LamboType, uppercase |
| Feature Heading | 27px (1.69rem) | 400 | 1.37 | normal | LamboType, uppercase |
| Card Title | 24px (1.50rem) | 400 | — | normal | LamboType |
| Body Large | 18px (1.13rem) | 400 | 1.56 | normal | LamboType, mixed case and uppercase variants |
| Body / UI | 16px (1.00rem) | 400/700 | 1.50 | normal/0.16px | LamboType, primary body text |
| Button Large | 16px (1.00rem) | 400 | 1.50 | normal | Gold CTA buttons |
| Button Standard | 14.4px (0.90rem) | 300/700 | 1.00 | 0.14–0.2px | LamboType, uppercase, ghost buttons |
| Button Small | 13px (0.81rem) | 300/500 | 1.20 | 0.13–0.2px | LamboType, compact button variant |
| Caption | 14px (0.88rem) | 600/700 | 1.14–1.50 | -0.42px | LamboType, uppercase, negative tracking |
| Label | 12px (0.75rem) | 400/500 | 1.83 | 0.96px | LamboType, uppercase badges and micro labels |
| Micro | 10px (0.63rem) | 400 | 1.00–2.00 | 0.225px | LamboType, uppercase, smallest text |
### Principles
- **ALL-CAPS is the default voice**: Display and feature headings are universally uppercase. This creates a shouting, commanding tone that matches the brand's aggression
- **Extreme scale range**: From 120px heroes to 10px micro labels — a 12:1 ratio that creates dramatic visual hierarchy
- **Tight line-heights at scale**: Display sizes use 0.92-1.19 line-height, creating dense, compressed blocks of type that feel stamped rather than typeset
- **Weight 400 dominates**: Unlike many design systems that use bold for emphasis, Lamborghini's regular weight carries the headlines — the typeface itself is so distinctive it doesn't need weight variation
- **Negative tracking on captions**: -0.42px letter-spacing on 14px captions creates a compressed, technical aesthetic
- **Positive tracking on micro text**: +0.225px at 10px ensures legibility at the smallest sizes
- **Single typeface discipline**: LamboType handles everything — the 12° angled terminals and hexagonal geometry provide visual coherence across all sizes
## 4. Component Stylings
### Buttons
All buttons use **zero border-radius** — sharp, angular rectangles that echo the aggressive lines of Lamborghini vehicles.
**Gold Accent CTA** — The primary action:
- Default: bg `#FFC000` (Lamborghini Gold), text `#000000`, padding 24px, fontSize 16px, fontWeight 400, borderRadius 0px, no border
- Hover: bg `#917300` (Dark Gold), darkens significantly
- Class: `btn-accent btn-large`
- Used for: "Discover More", "Tickets", "Start Configuration"
**Transparent Ghost** — The secondary action on dark backgrounds:
- Default: bg transparent, text `#FFFFFF`, border 1px solid `#FFFFFF`, padding 16px, opacity 0.5
- Hover: bg `#1EAEDB` (Teal Action), text white, opacity 0.7
- Focus: bg `#1EAEDB`, border 1px solid `#000000`, outline 2px solid `#000000`
- Used for: secondary CTAs on hero sections and dark panels
**White Filled** — Light-mode primary:
- Default: bg `#FFFFFF`, text `#202020`, no border
- Used for: CTAs on dark sections where gold isn't appropriate
**Black Filled** — Dark filled variant:
- Default: bg `#000000`, text `#202020`
- Used for: Inverted CTA on light sections
**Gray Neutral** — Subtle action:
- Default: bg `#969696`, text `#202020`
- Used for: secondary/tertiary actions, badge-like buttons
### Cards & Containers
- Background: `#202020` (Charcoal) on black canvas, or `#000000` on lighter sections
- Border: `0px 1px solid #202020` bottom borders for section dividers
- Border-radius: 0px (completely sharp corners)
- Shadow: minimal, uses overlay opacity for depth
- Content: full-bleed photography + overlaid text in white
### Inputs & Forms
- Minimal form presence on the marketing site
- Switch elements: border-radius 20px (the only rounded element), border 1px solid `#DDDDDD`
- Cookie banner input style: white text on black with `#7D7D7D` borders
### Navigation
- **Desktop**: Centered bull logo, "MENU" hamburger with icon on left, search icon + bookmarks icon on right
- **Background**: Transparent (inherits black page background)
- **Sticky**: Fixed to top, floats above content
- **No visible borders or shadows** — elements float in the darkness
- **"MENU" label**: White text at 14px weight 400, uppercase, accompanies hamburger icon
- **Hexagonal motifs**: Pause button on hero sections uses hexagonal outline shape
### Image Treatment
- **Hero**: Full-viewport video sections (100vh) with cinematic event/vehicle footage
- **Event photography**: Full-bleed aerial shots of Lamborghini Arena events
- **Vehicle imagery**: High-contrast studio shots on dark backgrounds, full-width
- **Aspect ratios**: Predominantly 16:9 and wider for cinematic feel
- **Dark gradient overlays**: Subtle darkening at top/bottom edges of video to ensure text legibility
### Distinctive Components
- **Hexagonal Pause Button**: Video control uses a hexagonal outline (matching the brand's geometric DNA from the typeface), positioned bottom-right of hero sections
- **Progress Bar**: Thin white line at bottom of hero sections indicating video/slide progress
- **Badge/Tag**: bg `#969696`, text white, padding 8px, fontSize 10px, borderRadius 2px — tiny metallic pills
## 5. Layout Principles
### Spacing System
- **Base unit**: 8px
- **Full scale**: 2px, 4px, 5px, 8px, 10px, 12px, 15px, 16px, 20px, 24px, 32px, 40px, 48px, 56px
- **Button padding**: 16px (ghost), 24px (gold accent)
- **Section padding**: 48–56px vertical, 40px horizontal
- **Small spacing**: 2–5px for fine adjustments (badge padding, border spacing)
### Grid & Container
- **Framework**: Bootstrap grid system (container + row + col)
- **Max width**: 1440px (largest breakpoint)
- **Columns**: Standard 12-column Bootstrap grid
- **Full-bleed**: Hero sections break out of grid to fill viewport edge-to-edge
- **Content areas**: Centered within 1200px max-width containers
### Whitespace Philosophy
Lamborghini uses darkness as whitespace. The generous black expanses between content blocks serve the same function as white space in a light design — creating breathing room that elevates each element to the status of exhibit. A model name floating in the middle of a black viewport has the same visual weight as a gallery piece on a white wall. The absence of color IS the design.
### Border Radius Scale
| Value | Context |
|-------|---------|
| 0px | Default for everything — buttons, cards, containers, images |
| 1px | Subtle span elements |
| 2px | Badges, close buttons, cookie elements — barely perceptible |
| 20px | Toggle switches only — the sole rounded element |
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Level 0 (Abyss) | `#000000` flat | Page background, deepest layer |
| Level 1 (Surface) | `#181818` or `#202020` | Cards, content panels, elevated sections |
| Level 2 (Overlay) | `rgba(0,0,0,0.7)` | Modal backdrops, video dimming |
| Level 3 (Fog) | `rgba(0,0,0,0.5)` | Lighter overlays, hover states |
| Level 4 (Mist) | `rgba(0,0,0,0.25)` | Subtle depth hints |
### Shadow Philosophy
Lamborghini achieves depth through surface color layering rather than shadows. On a black canvas, traditional drop shadows are invisible — instead, the system creates elevation by shifting from absolute black to progressively lighter dark grays: `#000000` → `#181818` → `#202020` → `#494949`. This "darkness gradient" approach means that elevated elements are literally lighter than their surroundings, inverting the traditional shadow model.
### Decorative Depth
- Full-bleed video provides atmospheric depth through cinematic lighting
- The hexagonal pause button floats with a thin white outline stroke
- Progress bars at hero section bottoms create a subtle horizon line
- No gradients, glows, or blur effects on UI elements — the photography provides all visual richness
## 7. Do's and Don'ts
### Do
- Use absolute black (`#000000`) as the primary background — never dark gray as a substitute
- Apply Lamborghini Gold (`#FFC000`) exclusively for primary CTA buttons — never for decorative purposes
- Set all display headings in uppercase with LamboType — the brand voice is always SHOUTING
- Use zero border-radius on buttons and cards — sharp angles are non-negotiable
- Maintain tight line-heights (0.92–1.19) on display type to create dense, architectural text blocks
- Use the transparent ghost button (white border, 50% opacity) as the secondary CTA on dark backgrounds
- Let full-viewport video/photography carry emotional weight — UI is infrastructure, not decoration
- Reserve hexagonal geometry for UI icons and the video control button
- Use weight 400 (regular) for headlines — the typeface is distinctive enough without bold emphasis
- Keep the gray palette achromatic — all neutrals are pure gray without color tinting
### Don't
- Introduce additional accent colors beyond gold — the monochrome-plus-gold system is sacred
- Apply border-radius to buttons or cards — curved edges contradict the angular vehicle aesthetic
- Use LamboType in italic or decorative styles — the brand is always upright and direct
- Add gradients to buttons or surfaces — depth comes from surface layering, not blending
- Use light backgrounds as the primary canvas — darkness is the default state, light is the exception
- Mix lowercase into display headings — the uppercase convention communicates authority and power
- Add hover animations with scale or translate — interactions should be color-only (background/opacity shifts)
- Use Open Sans for display text — LamboType must handle all visible typography
- Create busy layouts with many small elements — Lamborghini's design is about singular, bold statements
- Apply shadows to elements — on a black canvas, shadows are meaningless; use surface color shifts instead
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile Small | <425px | Single column, reduced type scale, stacked buttons |
| Mobile | 425-576px | Single column, hamburger nav, hero text ~40px |
| Tablet Small | 576-768px | 2-column grid begins, padding adjusts |
| Tablet | 768-1024px | 2-column layout, expanded hero, vehicle cards side-by-side |
| Desktop | 1024-1280px | Full navigation, 3+ column grids, display text at 80px |
| Desktop Large | 1280-1440px | Full layout, hero at 120px display, max-width containers |
| Wide | >1440px | Content centered, margins expand, hero fills viewport |
### Touch Targets
- Gold CTA buttons: 48px+ minimum height with 24px padding (exceeds WCAG 44×44px)
- Ghost buttons: 48px+ with 16px padding
- Hamburger menu: large touch target (~48px square)
- Hexagonal pause button: approximately 48px diameter
### Collapsing Strategy
- **Navigation**: Always hamburger-based ("MENU" + icon) — no horizontal nav expansion on any breakpoint
- **Hero video**: Maintains full-viewport height across all breakpoints, adjusting object-fit
- **Display type**: Scales from 120px (desktop) → 80px (tablet) → 54px/40px (mobile)
- **Button layout**: Side-by-side on desktop, stacks vertically on mobile
- **Grid columns**: 3-column → 2-column → 1-column progression
- **Section spacing**: Reduces from 56px → 40px → 24px vertical padding
### Image Behavior
- Hero videos use `object-fit: cover` to maintain cinematic framing at all sizes
- Vehicle images scale within their containers with maintained aspect ratios
- Event photography crops to viewport width on narrow screens
- Background images darken at edges to maintain text contrast on all viewports
## 9. Agent Prompt Guide
### Quick Color Reference
- Primary CTA: "Lamborghini Gold (#FFC000)"
- Background: "Absolute Black (#000000)"
- Surface: "Charcoal (#202020)"
- Heading text: "Pure White (#FFFFFF)"
- Body text: "Ash (#7D7D7D)"
- Link hover: "Link Blue (#3860BE)"
- Accent: "Cyan Pulse (#29ABE2)"
- Border: "Pure White (#FFFFFF) at 50% opacity"
### Example Component Prompts
- "Create a hero section with a full-viewport black background, the model name 'TEMERARIO' in LamboType at 120px uppercase weight 400 white text with 0.92 line-height, centered vertically, with a Lamborghini Gold (#FFC000) 'Discover More' button below — sharp corners, 0px radius, 24px padding, black text"
- "Design a transparent ghost button with 1px solid white border at 50% opacity, white text at 14.4px uppercase with 0.2px letter-spacing, padding 16px, on a black background — hover state changes to Teal Action (#1EAEDB) background with 70% opacity"
- "Build a navigation bar with zero visible background on absolute black, a centered bull logo, 'MENU' text label with hamburger icon on the left, and search + bookmark icons on the right — all in white, sticky position"
- "Create a news card grid on charcoal (#202020) background with white headlines at 27px uppercase, body text in #7D7D7D at 16px, and a white underlined 'Read More' link that turns #3860BE on hover"
- "Design a section divider using a 1px solid bottom border in #202020 on a black canvas — the elevation difference is purely through surface color shift, not shadow"
### Iteration Guide
When refining existing screens generated with this design system:
1. Focus on ONE component at a time — Lamborghini's system is extreme and every element must feel aggressive
2. Reference specific color names and hex codes from this document — the palette has only about 5 active colors
3. Use natural language descriptions, not CSS values — "sharp-cut golden rectangle" not "border-radius: 0px; background: #FFC000"
4. Describe the desired "feel" alongside specific measurements — "floating in total darkness" communicates the black canvas better than "background: #000000"
5. Remember that UPPERCASE IS THE DEFAULT — if text isn't uppercase at display sizes, it probably should be

> Conversion-focused design that removes friction and guides users toward action through clarity, trust, and speed.
## 1. Visual Theme & Atmosphere
Conversion-focused design that removes friction and guides users toward action through clarity, trust, and speed.
- **Visual style:** modern, clean
- **Color stance:** primary, neutral, success, warning, danger
- **Design intent:** Keep outputs recognizable to this style family while preserving usability and readability.
## 2. Color
- **Primary:** `#27272A` — Token from style foundations.
- **Secondary:** `#8B5CF6` — Token from style foundations.
- **Success:** `#16A34A` — Token from style foundations.
- **Warning:** `#D97706` — Token from style foundations.
- **Danger:** `#DC2626` — Token from style foundations.
- **Surface:** `#FFFFFF` — Token from style foundations.
- **Text:** `#111827` — Token from style foundations.
- **Neutral:** `#FFFFFF` — Derived from the surface token for official format compatibility.
- Favor Primary (#27272A) for CTA emphasis.
- Use Surface (#FFFFFF) for large backgrounds and cards.
- Keep body copy on Text (#111827) for legibility.
## 3. Typography
- **Scale:** 12/14/16/20/24/32
- **Families:** primary=Inter, display=Inter, mono=JetBrains Mono
- **Weights:** 100, 200, 300, 400, 500, 600, 700, 800, 900
- Headings should carry the style personality; body text should optimize scanability and contrast.
## 4. Spacing & Grid
- **Spacing scale:** 4/8/12/16/24/32
- Keep vertical rhythm consistent across sections and components.
- Align columns and modules to a predictable grid; avoid ad-hoc offsets.
## 5. Layout & Composition
- Prefer clear content blocks with consistent internal padding.
- Keep hierarchy obvious: headline → support text → primary action.
- Use whitespace to separate concerns before adding borders or shadows.
## 6. Components
- Buttons: primary action uses `#27272A`; secondary actions stay neutral.
- Inputs: strong focus-visible states, clear labels, and predictable error messaging.
- Cards/sections: use consistent radii, spacing, and elevation strategy across the page.
## 7. Motion & Interaction
- Use subtle transitions that emphasize Primary (#27272A) as the interaction signal.
- Default to short, purposeful transitions (150–250ms) with stable easing.
- Ensure hover, focus-visible, active, disabled, and loading states are explicit.
## 8. Voice & Brand
- Tone should reflect the visual style: concise, confident, and product-specific.
- Keep microcopy action-oriented and avoid generic filler language.
- Preserve the style identity in headlines while keeping UI labels literal and clear.
## 9. Anti-patterns
- Do not introduce off-palette colors when an existing token can solve the problem.
- Do not flatten hierarchy by using the same type size/weight for all text.
- Do not add decorative effects that reduce readability or accessibility.
- Do not mix unrelated visual metaphors in the same interface.

# Design System Inspired by Linear
> Category: Productivity & SaaS
> Project management. Ultra-minimal, precise, purple accent.
## 1. Visual Theme & Atmosphere
Linear's website is a masterclass in dark-mode-first product design — a near-black canvas (`#08090a`) where content emerges from darkness like starlight. The overall impression is one of extreme precision engineering: every element exists in a carefully calibrated hierarchy of luminance, from barely-visible borders (`rgba(255,255,255,0.05)`) to soft, luminous text (`#f7f8f8`). This is not a dark theme applied to a light design — it is darkness as the native medium, where information density is managed through subtle gradations of white opacity rather than color variation.
The typography system is built entirely on Inter Variable with OpenType features `"cv01"` and `"ss03"` enabled globally, giving the typeface a cleaner, more geometric character. Inter is used at a remarkable range of weights — from 300 (light body) through 510 (medium, Linear's signature weight) to 590 (semibold emphasis). The 510 weight is particularly distinctive: it sits between regular and medium, creating a subtle emphasis that doesn't shout. At display sizes (72px, 64px, 48px), Inter uses aggressive negative letter-spacing (-1.584px to -1.056px), creating compressed, authoritative headlines that feel engineered rather than designed. Berkeley Mono serves as the monospace companion for code and technical labels, with fallbacks to ui-monospace, SF Mono, and Menlo.
The color system is almost entirely achromatic — dark backgrounds with white/gray text — punctuated by a single brand accent: Linear's signature indigo-violet (`#5e6ad2` for backgrounds, `#7170ff` for interactive accents). This accent color is used sparingly and intentionally, appearing only on CTAs, active states, and brand elements. The border system uses ultra-thin, semi-transparent white borders (`rgba(255,255,255,0.05)` to `rgba(255,255,255,0.08)`) that create structure without visual noise, like wireframes drawn in moonlight.
**Key Characteristics:**
- Dark-mode-native: `#08090a` marketing background, `#0f1011` panel background, `#191a1b` elevated surfaces
- Inter Variable with `"cv01", "ss03"` globally — geometric alternates for a cleaner aesthetic
- Signature weight 510 (between regular and medium) for most UI text
- Aggressive negative letter-spacing at display sizes (-1.584px at 72px, -1.056px at 48px)
- Brand indigo-violet: `#5e6ad2` (bg) / `#7170ff` (accent) / `#828fff` (hover) — the only chromatic color in the system
- Semi-transparent white borders throughout: `rgba(255,255,255,0.05)` to `rgba(255,255,255,0.08)`
- Button backgrounds at near-zero opacity: `rgba(255,255,255,0.02)` to `rgba(255,255,255,0.05)`
- Multi-layered shadows with inset variants for depth on dark surfaces
- Radix UI primitives as the component foundation (6 detected primitives)
- Success green (`#27a644`, `#10b981`) used only for status indicators
## 2. Color Palette & Roles
### Background Surfaces
- **Marketing Black** (`#010102` / `#08090a`): The deepest background — the canvas for hero sections and marketing pages. Near-pure black with an imperceptible blue-cool undertone.
- **Panel Dark** (`#0f1011`): Sidebar and panel backgrounds. One step up from the marketing black.
- **Level 3 Surface** (`#191a1b`): Elevated surface areas, card backgrounds, dropdowns.
- **Secondary Surface** (`#28282c`): The lightest dark surface — used for hover states and slightly elevated components.
### Text & Content
- **Primary Text** (`#f7f8f8`): Near-white with a barely-warm cast. The default text color — not pure white, preventing eye strain on dark backgrounds.
- **Secondary Text** (`#d0d6e0`): Cool silver-gray for body text, descriptions, and secondary content.
- **Tertiary Text** (`#8a8f98`): Muted gray for placeholders, metadata, and de-emphasized content.
- **Quaternary Text** (`#62666d`): The most subdued text — timestamps, disabled states, subtle labels.
### Brand & Accent
- **Brand Indigo** (`#5e6ad2`): Primary brand color — used for CTA button backgrounds, brand marks, and key interactive surfaces.
- **Accent Violet** (`#7170ff`): Brighter variant for interactive elements — links, active states, selected items.
- **Accent Hover** (`#828fff`): Lighter, more saturated variant for hover states on accent elements.
- **Security Lavender** (`#7a7fad`): Muted indigo used specifically for security-related UI elements.
### Status Colors
- **Green** (`#27a644`): Primary success/active status. Used for "in progress" indicators.
- **Emerald** (`#10b981`): Secondary success — pill badges, completion states.
### Border & Divider
- **Border Primary** (`#23252a`): Solid dark border for prominent separations.
- **Border Secondary** (`#34343a`): Slightly lighter solid border.
- **Border Tertiary** (`#3e3e44`): Lightest solid border variant.
- **Border Subtle** (`rgba(255,255,255,0.05)`): Ultra-subtle semi-transparent border — the default.
- **Border Standard** (`rgba(255,255,255,0.08)`): Standard semi-transparent border for cards, inputs, code blocks.
- **Line Tint** (`#141516`): Nearly invisible line for the subtlest divisions.
- **Line Tertiary** (`#18191a`): Slightly more visible divider line.
### Light Mode Neutrals (for light theme contexts)
- **Light Background** (`#f7f8f8`): Page background in light mode.
- **Light Surface** (`#f3f4f5` / `#f5f6f7`): Subtle surface tinting.
- **Light Border** (`#d0d6e0`): Visible border in light contexts.
- **Light Border Alt** (`#e6e6e6`): Alternative lighter border.
- **Pure White** (`#ffffff`): Card surfaces, highlights.
### Overlay
- **Overlay Primary** (`rgba(0,0,0,0.85)`): Modal/dialog backdrop — extremely dark for focus isolation.
## 3. Typography Rules
### Font Family
- **Primary**: `Inter Variable`, with fallbacks: `SF Pro Display, -apple-system, system-ui, Segoe UI, Roboto, Oxygen, Ubuntu, Cantarell, Open Sans, Helvetica Neue`
- **Monospace**: `Berkeley Mono`, with fallbacks: `ui-monospace, SF Mono, Menlo`
- **OpenType Features**: `"cv01", "ss03"` enabled globally — cv01 provides an alternate lowercase 'a' (single-story), ss03 adjusts specific letterforms for a cleaner geometric appearance.

| Mono Label | Berkeley Mono | 12px (0.75rem) | 400 | 1.40 | normal | Code metadata, sometimes uppercase |
### Principles
- **510 is the signature weight**: Linear uses Inter Variable's 510 weight (between regular 400 and medium 500) as its default emphasis weight. This creates a subtly bolded feel without the heaviness of traditional medium or semibold.
- **Compression at scale**: Display sizes use progressively tighter letter-spacing — -1.584px at 72px, -1.408px at 64px, -1.056px at 48px, -0.704px at 32px. Below 24px, spacing relaxes toward normal.
- **OpenType as identity**: `"cv01", "ss03"` aren't decorative — they transform Inter into Linear's distinctive typeface, giving it a more geometric, purposeful character.
- **Three-tier weight system**: 400 (reading), 510 (emphasis/UI), 590 (strong emphasis). The 300 weight appears only in deliberately de-emphasized contexts.

## 5. Layout Principles
### Spacing System
- Base unit: 8px
- Scale: 1px, 4px, 7px, 8px, 11px, 12px, 16px, 19px, 20px, 22px, 24px, 28px, 32px, 35px
- The 7px and 11px values suggest micro-adjustments for optical alignment
- Primary rhythm: 8px, 16px, 24px, 32px (standard 8px grid)
### Grid & Container
- Max content width: approximately 1200px
- Hero: centered single-column with generous vertical padding
- Feature sections: 2–3 column grids for feature cards
- Full-width dark sections with internal max-width constraints
- Changelog: single-column timeline layout
### Whitespace Philosophy
- **Darkness as space**: On Linear's dark canvas, empty space isn't white — it's absence. The near-black background IS the whitespace, and content emerges from it.
- **Compressed headlines, expanded surroundings**: Display text at 72px with -1.584px tracking is dense and compressed, but sits within vast dark padding. The contrast between typographic density and spatial generosity creates tension.
- **Section isolation**: Each feature section is separated by generous vertical padding (80px+) with no visible dividers — the dark background provides natural separation.
### Border Radius Scale
- Micro (2px): Inline badges, toolbar buttons, subtle tags
- Standard (4px): Small containers, list items
- Comfortable (6px): Buttons, inputs, functional elements
- Card (8px): Cards, dropdowns, popovers
- Panel (12px): Panels, featured cards, section containers
- Large (22px): Large panel elements
- Full Pill (9999px): Chips, filter pills, status tags
- Circle (50%): Icon buttons, avatars, status dots
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow, `#010102` bg | Page background, deepest canvas |
| Subtle (Level 1) | `rgba(0,0,0,0.03) 0px 1.2px 0px` | Toolbar buttons, micro-elevation |
| Surface (Level 2) | `rgba(255,255,255,0.05)` bg + `1px solid rgba(255,255,255,0.08)` border | Cards, input fields, containers |
| Inset (Level 2b) | `rgba(0,0,0,0.2) 0px 0px 12px 0px inset` | Recessed panels, inner shadows |
| Ring (Level 3) | `rgba(0,0,0,0.2) 0px 0px 0px 1px` | Border-as-shadow technique |
| Elevated (Level 4) | `rgba(0,0,0,0.4) 0px 2px 4px` | Floating elements, dropdowns |
| Dialog (Level 5) | Multi-layer stack: `rgba(0,0,0,0) 0px 8px 2px, rgba(0,0,0,0.01) 0px 5px 2px, rgba(0,0,0,0.04) 0px 3px 2px, rgba(0,0,0,0.07) 0px 1px 1px, rgba(0,0,0,0.08) 0px 0px 1px` | Popovers, command palette, modals |
| Focus | `rgba(0,0,0,0.1) 0px 4px 12px` + additional layers | Keyboard focus on interactive elements |
**Shadow Philosophy**: On dark surfaces, traditional shadows (dark on dark) are nearly invisible. Linear solves this by using semi-transparent white borders as the primary depth indicator. Elevation isn't communicated through shadow darkness but through background luminance steps — each level slightly increases the white opacity of the surface background (`0.02` → `0.04` → `0.05`), creating a subtle stacking effect. The inset shadow technique (`rgba(0,0,0,0.2) 0px 0px 12px 0px inset`) creates a unique "sunken" effect for recessed panels, adding dimensional depth that traditional dark themes lack.
## 7. Do's and Don'ts
### Do
- Use Inter Variable with `"cv01", "ss03"` on ALL text — these features are fundamental to Linear's typeface identity
- Use weight 510 as your default emphasis weight — it's Linear's signature between-weight
- Apply aggressive negative letter-spacing at display sizes (-1.584px at 72px, -1.056px at 48px)
- Build on near-black backgrounds: `#08090a` for marketing, `#0f1011` for panels, `#191a1b` for elevated surfaces
- Use semi-transparent white borders (`rgba(255,255,255,0.05)` to `rgba(255,255,255,0.08)`) instead of solid dark borders
- Keep button backgrounds nearly transparent: `rgba(255,255,255,0.02)` to `rgba(255,255,255,0.05)`
- Reserve brand indigo (`#5e6ad2` / `#7170ff`) for primary CTAs and interactive accents only
- Use `#f7f8f8` for primary text — not pure `#ffffff`, which would be too harsh
- Apply the luminance stacking model: deeper = darker bg, elevated = slightly lighter bg
### Don't
- Don't use pure white (`#ffffff`) as primary text — `#f7f8f8` prevents eye strain
- Don't use solid colored backgrounds for buttons — transparency is the system (rgba white at 0.02–0.05)
- Don't apply the brand indigo decoratively — it's reserved for interactive/CTA elements only
- Don't use positive letter-spacing on display text — Inter at large sizes always runs negative
- Don't use visible/opaque borders on dark backgrounds — borders should be whisper-thin semi-transparent white
- Don't skip the OpenType features (`"cv01", "ss03"`) — without them, it's generic Inter, not Linear's Inter
- Don't use weight 700 (bold) — Linear's maximum weight is 590, with 510 as the workhorse
- Don't introduce warm colors into the UI chrome — the palette is cool gray with blue-violet accent only
- Don't use drop shadows for elevation on dark surfaces — use background luminance stepping instead
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile Small | <600px | Single column, compact padding |
| Mobile | 600–640px | Standard mobile layout |
| Tablet | 640–768px | Two-column grids begin |
| Desktop Small | 768–1024px | Full card grids, expanded padding |
| Desktop | 1024–1280px | Standard desktop, full navigation |
| Large Desktop | >1280px | Full layout, generous margins |
### Touch Targets
- Buttons use comfortable padding with 6px radius minimum
- Navigation links at 13–14px with adequate spacing
- Pill tags have 10px horizontal padding for touch accessibility
- Icon buttons at 50% radius ensure circular, easy-to-tap targets
- Search trigger is prominently placed with generous hit area
### Collapsing Strategy
- Hero: 72px → 48px → 32px display text, tracking adjusts proportionally
- Navigation: horizontal links + CTAs → hamburger menu at 768px
- Feature cards: 3-column → 2-column → single column stacked
- Product screenshots: maintain aspect ratio, may reduce padding
- Changelog: timeline maintains single-column through all sizes
- Footer: multi-column → stacked single column
- Section spacing: 80px+ → 48px on mobile
### Image Behavior
- Dashboard screenshots maintain border treatment at all sizes
- Hero visuals simplify on mobile (fewer floating UI elements)
- Product screenshots use responsive sizing with consistent radius
- Dark background ensures screenshots blend naturally at any viewport

- "Create a hero section on `#08090a` background. Headline at 48px Inter Variable weight 510, line-height 1.00, letter-spacing -1.056px, color `#f7f8f8`, font-feature-settings `'cv01', 'ss03'`. Subtitle at 18px weight 400, line-height 1.60, color `#8a8f98`. Brand CTA button (`#5e6ad2`, 6px radius, 8px 16px padding) and ghost button (`rgba(255,255,255,0.02)` bg, `1px solid rgba(255,255,255,0.08)` border, 6px radius)."
- "Design a card on dark background: `rgba(255,255,255,0.02)` background, `1px solid rgba(255,255,255,0.08)` border, 8px radius. Title at 20px Inter Variable weight 590, letter-spacing -0.24px, color `#f7f8f8`. Body at 15px weight 400, color `#8a8f98`, letter-spacing -0.165px."
- "Build a pill badge: transparent background, `#d0d6e0` text, 9999px radius, 0px 10px padding, `1px solid #23252a` border, 12px Inter Variable weight 510."
- "Create navigation: dark sticky header on `#0f1011`. Inter Variable 13px weight 510 for links, `#d0d6e0` text. Brand indigo CTA `#5e6ad2` right-aligned with 6px radius. Bottom border: `1px solid rgba(255,255,255,0.05)`."
- "Design a command palette: `#191a1b` background, `1px solid rgba(255,255,255,0.08)` border, 12px radius, multi-layer shadow stack. Input at 16px Inter Variable weight 400, `#f7f8f8` text. Results list with 13px weight 510 labels in `#d0d6e0` and 12px metadata in `#62666d`."
### Iteration Guide
1. Always set font-feature-settings `"cv01", "ss03"` on all Inter text — this is non-negotiable for Linear's look
2. Letter-spacing scales with font size: -1.584px at 72px, -1.056px at 48px, -0.704px at 32px, normal below 16px
3. Three weights: 400 (read), 510 (emphasize/navigate), 590 (announce)
4. Surface elevation via background opacity: `rgba(255,255,255, 0.02 → 0.04 → 0.05)` — never solid backgrounds on dark
5. Brand indigo (`#5e6ad2` / `#7170ff`) is the only chromatic color — everything else is grayscale
6. Borders are always semi-transparent white, never solid dark colors on dark backgrounds
7. Berkeley Mono for any code or technical content, Inter Variable for everything else

# Design System Inspired by Lovable
> Category: Developer Tools
> AI full-stack builder. Playful gradients, friendly dev aesthetic.
## 1. Visual Theme & Atmosphere
Lovable's website radiates warmth through restraint. The entire page sits on a creamy, parchment-toned background (`#f7f4ed`) that immediately separates it from the cold-white conventions of most developer tool sites. This isn't minimalism for minimalism's sake — it's a deliberate choice to feel approachable, almost analog, like a well-crafted notebook. The near-black text (`#1c1c1c`) against this warm cream creates a contrast ratio that's easy on the eyes while maintaining sharp readability.
The custom Camera Plain Variable typeface is the system's secret weapon. Unlike geometric sans-serifs that signal "tech company," Camera Plain has a humanist warmth — slightly rounded terminals, organic curves, and a comfortable reading rhythm. At display sizes (48px–60px), weight 600 with aggressive negative letter-spacing (-0.9px to -1.5px) compresses headlines into confident, editorial statements. The font uses `ui-sans-serif, system-ui` as fallbacks, acknowledging that the custom typeface carries the brand personality.
What makes Lovable's visual system distinctive is its opacity-driven depth model. Rather than using a traditional gray scale, the system modulates `#1c1c1c` at varying opacities (0.03, 0.04, 0.4, 0.82–0.83) to create a unified tonal range. Every shade of gray on the page is technically the same hue — just more or less transparent. This creates a visual coherence that's nearly impossible to achieve with arbitrary hex values. The border system follows suit: `1px solid #eceae4` for light divisions and `1px solid rgba(28, 28, 28, 0.4)` for stronger interactive boundaries.
**Key Characteristics:**
- Warm parchment background (`#f7f4ed`) — not white, not beige, a deliberate cream that feels hand-selected
- Camera Plain Variable typeface with humanist warmth and editorial letter-spacing at display sizes
- Opacity-driven color system: all grays derived from `#1c1c1c` at varying transparency levels
- Inset shadow technique on buttons: `rgba(255,255,255,0.2) 0px 0.5px 0px 0px inset, rgba(0,0,0,0.2) 0px 0px 0px 0.5px inset`
- Warm neutral border palette: `#eceae4` for subtle, `rgba(28,28,28,0.4)` for interactive elements
- Full-pill radius (`9999px`) used extensively for action buttons and icon containers
- Focus state uses `rgba(0,0,0,0.1) 0px 4px 12px` shadow for soft, warm emphasis
- shadcn/ui + Radix UI component primitives with Tailwind CSS utility styling
## 2. Color Palette & Roles
### Primary
- **Cream** (`#f7f4ed`): Page background, card surfaces, button surfaces. The foundation — warm, paper-like, human.
- **Charcoal** (`#1c1c1c`): Primary text, headings, dark button backgrounds. Not pure black — organic warmth.
- **Off-White** (`#fcfbf8`): Button text on dark backgrounds, subtle highlight. Barely distinguishable from pure white.
### Neutral Scale (Opacity-Based)
- **Charcoal 100%** (`#1c1c1c`): Primary text, headings, dark surfaces.
- **Charcoal 83%** (`rgba(28,28,28,0.83)`): Strong secondary text.
- **Charcoal 82%** (`rgba(28,28,28,0.82)`): Body copy.
- **Muted Gray** (`#5f5f5d`): Secondary text, descriptions, captions.
- **Charcoal 40%** (`rgba(28,28,28,0.4)`): Interactive borders, button outlines.
- **Charcoal 4%** (`rgba(28,28,28,0.04)`): Subtle hover backgrounds, micro-tints.
- **Charcoal 3%** (`rgba(28,28,28,0.03)`): Barely-visible overlays, background depth.
### Surface & Border
- **Light Cream** (`#eceae4`): Card borders, dividers, image outlines. The warm divider line.
- **Cream Surface** (`#f7f4ed`): Card backgrounds, section fills — same as page background for seamless integration.
### Interactive
- **Ring Blue** (`#3b82f6` at 50% opacity): `--tw-ring-color`, Tailwind focus ring.
- **Focus Shadow** (`rgba(0,0,0,0.1) 0px 4px 12px`): Focus and active state shadow — soft, warm, diffused.
### Inset Shadows
- **Button Inset** (`rgba(255,255,255,0.2) 0px 0.5px 0px 0px inset, rgba(0,0,0,0.2) 0px 0px 0px 0.5px inset, rgba(0,0,0,0.05) 0px 1px 2px 0px`): The signature multi-layer inset shadow on dark buttons.
## 3. Typography Rules
### Font Family
- **Primary**: `Camera Plain Variable`, with fallbacks: `ui-sans-serif, system-ui`
- **Weight range**: 400 (body/reading), 480 (special display), 600 (headings/emphasis)
- **Feature**: Variable font with continuous weight axis — allows fine-tuned intermediary weights like 480.
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display Hero | Camera Plain Variable | 60px (3.75rem) | 600 | 1.00–1.10 (tight) | -1.5px | Maximum impact, editorial |
| Display Alt | Camera Plain Variable | 60px (3.75rem) | 480 | 1.00 (tight) | normal | Lighter hero variant |
| Section Heading | Camera Plain Variable | 48px (3.00rem) | 600 | 1.00 (tight) | -1.2px | Feature section titles |
| Sub-heading | Camera Plain Variable | 36px (2.25rem) | 600 | 1.10 (tight) | -0.9px | Sub-sections |
| Card Title | Camera Plain Variable | 20px (1.25rem) | 400 | 1.25 (tight) | normal | Card headings |
| Body Large | Camera Plain Variable | 18px (1.13rem) | 400 | 1.38 | normal | Introductions |
| Body | Camera Plain Variable | 16px (1.00rem) | 400 | 1.50 | normal | Standard reading text |
| Button | Camera Plain Variable | 16px (1.00rem) | 400 | 1.50 | normal | Button labels |
| Button Small | Camera Plain Variable | 14px (0.88rem) | 400 | 1.50 | normal | Compact buttons |
| Link | Camera Plain Variable | 16px (1.00rem) | 400 | 1.50 | normal | Underline decoration |
| Link Small | Camera Plain Variable | 14px (0.88rem) | 400 | 1.50 | normal | Footer links |
| Caption | Camera Plain Variable | 14px (0.88rem) | 400 | 1.50 | normal | Metadata, small text |
### Principles
- **Warm humanist voice**: Camera Plain Variable gives Lovable its approachable personality. The slightly rounded terminals and organic curves contrast with the sharp geometric sans-serifs used by most developer tools.
- **Variable weight as design tool**: The font supports continuous weight values (e.g., 480), enabling nuanced hierarchy beyond standard weight stops. Weight 480 at 60px creates a display style that feels lighter than semibold but stronger than regular.
- **Compression at scale**: Headlines use negative letter-spacing (-0.9px to -1.5px) for editorial impact. Body text stays at normal tracking for comfortable reading.
- **Two weights, clear roles**: 400 (body/UI/links/buttons) and 600 (headings/emphasis). The narrow weight range creates hierarchy through size and spacing, not weight variation.

## 5. Layout Principles
### Spacing System
- Base unit: 8px
- Scale: 8px, 10px, 12px, 16px, 24px, 32px, 40px, 56px, 80px, 96px, 128px, 176px, 192px, 208px
- The scale expands generously at the top end — sections use 80px–208px vertical spacing for editorial breathing room
### Grid & Container
- Max content width: approximately 1200px (centered)
- Hero: centered single-column with massive vertical padding (96px+)
- Feature sections: 2–3 column grids
- Full-width footer with multi-column link layout
- Showcase sections with centered card grids
### Whitespace Philosophy
- **Editorial generosity**: Lovable's spacing is lavish at section boundaries (80px–208px). The warm cream background makes these expanses feel cozy rather than empty.
- **Content-driven rhythm**: Tight internal spacing within cards (12–24px) contrasts with wide section gaps, creating a reading rhythm that alternates between focused content and visual rest.
- **Section separation**: Footer uses `1px solid #eceae4` border and 16px radius container. Sections defined by generous spacing rather than border lines.
### Border Radius Scale
- Micro (4px): Small buttons, interactive elements
- Standard (6px): Buttons, inputs, navigation menu
- Comfortable (8px): Compact cards, divs
- Card (12px): Standard cards, image containers, templates
- Container (16px): Large containers, footer sections
- Full Pill (9999px): Action pills, icon buttons, toggles
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow, cream background | Page surface, most content |
| Bordered (Level 1) | `1px solid #eceae4` | Cards, images, dividers |
| Inset (Level 2) | `rgba(255,255,255,0.2) 0px 0.5px 0px inset, rgba(0,0,0,0.2) 0px 0px 0px 0.5px inset, rgba(0,0,0,0.05) 0px 1px 2px` | Dark buttons, primary actions |
| Focus (Level 3) | `rgba(0,0,0,0.1) 0px 4px 12px` | Active/focus states |
| Ring (Accessibility) | `rgba(59,130,246,0.5)` 2px ring | Keyboard focus on inputs |
**Shadow Philosophy**: Lovable's depth system is intentionally shallow. Instead of floating cards with dramatic drop-shadows, the system relies on warm borders (`#eceae4`) against the cream surface to create gentle containment. The only notable shadow pattern is the inset shadow on dark buttons — a subtle multi-layer technique where a white highlight line sits at the top edge while a dark ring and soft drop handle the bottom. This creates a tactile, pressed-into-surface feeling rather than a hovering-above-surface feeling. The warm focus shadow (`rgba(0,0,0,0.1) 0px 4px 12px`) is deliberately diffused and large, creating a soft glow rather than a sharp outline.
### Decorative Depth
- Hero: soft, warm multi-color gradient wash (pinks, oranges, blues) behind hero — atmospheric, barely visible
- Footer: gradient background with warm tones transitioning to the bottom
- No harsh section dividers — spacing and background warmth handle transitions
## 7. Do's and Don'ts
### Do
- Use the warm cream background (`#f7f4ed`) as the page foundation — it's the brand's signature warmth
- Use Camera Plain Variable at display sizes with negative letter-spacing (-0.9px to -1.5px)
- Derive all grays from `#1c1c1c` at varying opacity levels for tonal unity
- Use the inset shadow technique on dark buttons for tactile depth
- Use `#eceae4` borders instead of shadows for card containment
- Keep the weight system narrow: 400 for body/UI, 600 for headings
- Use full-pill radius (9999px) only for action pills and icon buttons
- Apply opacity 0.8 on active states for responsive tactile feedback
### Don't
- Don't use pure white (`#ffffff`) as a page background — the cream is intentional
- Don't use heavy box-shadows for cards — borders are the containment mechanism
- Don't introduce saturated accent colors — the palette is intentionally warm-neutral
- Don't use weight 700 (bold) — 600 is the maximum weight in the system
- Don't apply 9999px radius on rectangular buttons — pills are for icon/action toggles
- Don't use sharp focus outlines — the system uses soft shadow-based focus indicators
- Don't mix border styles — `#eceae4` for passive, `rgba(28,28,28,0.4)` for interactive
- Don't increase letter-spacing on headings — Camera Plain is designed to run tight at scale
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile Small | <600px | Tight single column, reduced padding |
| Mobile | 600–640px | Standard mobile layout |
| Tablet Small | 640–700px | 2-column grids begin |
| Tablet | 700–768px | Card grids expand |
| Desktop Small | 768–1024px | Multi-column layouts |
| Desktop | 1024–1280px | Full feature layout |
| Large Desktop | 1280–1536px | Maximum content width, generous margins |
### Touch Targets
- Buttons: 8px 16px padding (comfortable touch)
- Navigation: adequate spacing between items
- Pill buttons: 9999px radius creates large tap-friendly targets
- Menu toggle: 6px radius button with adequate sizing
### Collapsing Strategy
- Hero: 60px → 48px → 36px headline scaling with proportional letter-spacing
- Navigation: horizontal links → hamburger menu at 768px
- Feature cards: 3-column → 2-column → single column stacked
- Template gallery: grid → stacked vertical cards
- Stats bar: horizontal → stacked vertical
- Footer: multi-column → stacked single column
- Section spacing: 128px+ → 64px on mobile
### Image Behavior
- Template screenshots maintain `1px solid #eceae4` border at all sizes
- 12px border radius preserved across breakpoints
- Gallery images responsive with consistent aspect ratios
- Hero gradient softens/simplifies on mobile
## 9. Agent Prompt Guide
### Quick Color Reference
- Primary CTA: Charcoal (`#1c1c1c`)
- Background: Cream (`#f7f4ed`)
- Heading text: Charcoal (`#1c1c1c`)
- Body text: Muted Gray (`#5f5f5d`)
- Border: `#eceae4` (passive), `rgba(28,28,28,0.4)` (interactive)
- Focus: `rgba(0,0,0,0.1) 0px 4px 12px`
- Button text on dark: `#fcfbf8`
### Example Component Prompts
- "Create a hero section on cream background (#f7f4ed). Headline at 60px Camera Plain Variable weight 600, line-height 1.10, letter-spacing -1.5px, color #1c1c1c. Subtitle at 18px weight 400, line-height 1.38, color #5f5f5d. Dark CTA button (#1c1c1c bg, #fcfbf8 text, 6px radius, 8px 16px padding, inset shadow) and ghost button (transparent bg, 1px solid rgba(28,28,28,0.4) border, 6px radius)."
- "Design a card on cream (#f7f4ed) background. Border: 1px solid #eceae4. Radius 12px. No box-shadow. Title at 20px Camera Plain Variable weight 400, line-height 1.25, color #1c1c1c. Body at 14px weight 400, color #5f5f5d."
- "Build a template gallery: grid of cards with 12px radius, 1px solid #eceae4 border, cream backgrounds. Each card: image with 12px top radius, title below. Hover: subtle border darkening."
- "Create navigation: sticky on cream (#f7f4ed). Camera Plain 16px weight 400 for links, #1c1c1c text. Dark CTA button right-aligned with inset shadow. Mobile: hamburger menu with 6px radius."
- "Design a stats section: large numbers at 48px Camera Plain weight 600, letter-spacing -1.2px, #1c1c1c. Labels below at 16px weight 400, #5f5f5d. Horizontal layout with 32px gap."
### Iteration Guide
1. Always use cream (`#f7f4ed`) as the base — never pure white
2. Derive grays from `#1c1c1c` at opacity levels rather than using distinct hex values
3. Use `#eceae4` borders for containment, not shadows
4. Letter-spacing scales with size: -1.5px at 60px, -1.2px at 48px, -0.9px at 36px, normal at 16px
5. Two weights: 400 (everything except headings) and 600 (headings)
6. The inset shadow on dark buttons is the signature detail — don't skip it
7. Camera Plain Variable at weight 480 is for special display moments only

- Buttons: primary action uses `#FAFAFA`; secondary actions stay neutral.
- Inputs: strong focus-visible states, clear labels, and predictable error messaging.
- Cards/sections: use consistent radii, spacing, and elevation strategy across the page.
## 7. Motion & Interaction
- Use subtle transitions that emphasize Primary (#FAFAFA) as the interaction signal.
- Default to short, purposeful transitions (150–250ms) with stable easing.
- Ensure hover, focus-visible, active, disabled, and loading states are explicit.
## 8. Voice & Brand
- Tone should reflect the visual style: concise, confident, and product-specific.
- Keep microcopy action-oriented and avoid generic filler language.
- Preserve the style identity in headlines while keeping UI labels literal and clear.
## 9. Anti-patterns
- Do not introduce off-palette colors when an existing token can solve the problem.
- Do not flatten hierarchy by using the same type size/weight for all text.
- Do not add decorative effects that reduce readability or accessibility.
- Do not mix unrelated visual metaphors in the same interface.

# Design System Inspired by Mastercard
> Category: Fintech & Crypto
> Global payments network. Warm cream canvas, orbital pill shapes, editorial warmth.
## 1. Visual Theme & Atmosphere
Mastercard's experience reads like a warm, editorial magazine built from soft stone and signal orange. The canvas is a muted putty-cream (`#F3F0EE`) — not white, not gray, but a color that feels like the paper of a premium annual report. On top of that canvas, everything that matters is shaped like a stadium, a pill, or a perfect circle. The dominant visual gesture is the **oversized radius**: heroes carry 40-point corners, cards go fully pill-shaped, service images are cropped into circular orbits, and buttons either complete the pill or fit snugly at 20 points. There are almost no sharp corners anywhere on the page.
The second gesture is **orbit and trajectory**. Circular image masks don't sit still — they're connected by thin, hand-drawn-feeling orange arcs that span entire viewport widths, implying a constellation of services rather than a list. Each circle has a small attached "satellite" — a white micro-CTA holding an arrow icon — docked onto its perimeter like a moon. This is the most distinctive thing about Mastercard's current design language: the circles feel like they're in motion even though the page is still.
Typography is rendered entirely in **MarkForMC**, Mastercard's proprietary geometric sans. Headlines are set at a medium weight (500) with tight negative letter-spacing (-2%), giving them confidence without shouting. Body copy runs at the same family in a slightly lighter weight (450) — a weight you rarely see on the web, chosen because it reads softer than regular 400 without feeling thin. The whole system — warm cream surfaces, pill shapes, circular portraits, traced-orange orbits, black CTAs — feels simultaneously institutional (a 60-year-old payments network) and editorial (a modern brand magazine), which is exactly the tension Mastercard wants to hold.
**Key Characteristics:**
- Warm cream canvas (`#F3F0EE`) replaces traditional white — every surface is tinted, never sterile
- Extreme border-radius as design language: 40px, 99px, 1000px dominate; anything square is a cookie-banner third-party
- Circular image portraits with attached white satellite-CTAs and traced-orange orbital paths
- Ghost "watermark" headlines (cream-on-cream text at heading scale) layered behind circle portraits
- Black primary CTAs with 20px radius in the body — the cookie-banner orange is kept to consent flows
- Floating pill-shaped navigation that docks below the viewport top with rounded shoulders
- Eyebrow labels with a tiny accent dot + uppercase bold tracking — used as the section-category signal
- Dark warm-black footer (`#141413`) with four-column link layout and large conversational headline
## 2. Color Palette & Roles
### Primary
- **Mastercard Red** (`#EB001B`): The left circle of the Mastercard mark — used only in the brand logo, never as a UI color.
- **Mastercard Yellow** (`#F79E1B`): The right circle of the Mastercard mark — used only in the brand logo, never as a UI color.
- **Ink Black** (`#141413`): The warm near-black used for primary CTAs, headline text on cream, and the footer surface. Slightly warm (the `13` blue value pulls toward the cream) so it never feels jet-black on the warm canvas.
### Secondary & Accent
- **Signal Orange** (`#CF4500`): The burnt/rust CTA orange used on consent actions and eyebrow dots. Deeper than the brand yellow, brighter than ink — it's the page's single aggressive color and must be used sparingly.
- **Light Signal Orange** (`#F37338`): A lighter carroty orange used for carousel active indicators and decorative orbital arcs. Always acts as an attention cue, never as body color.
- **Clay Brown** (`#9A3A0A`): The deep rust used for secondary link-style buttons (e.g., cookie details). Sits between ink and signal orange.
### Surface & Background
- **Canvas Cream** (`#F3F0EE`): The page canvas. Warm, putty-toned, the default body background. All editorial sections sit on this.
- **Lifted Cream** (`#FCFBFA`): One step lighter than canvas — used for nested "raised" sections that want to feel like paper laid on paper.
- **White** (`#FFFFFF`): Reserved for the floating navigation pill, modal cards, secondary button fills, and small satellite-CTA circles attached to image portraits.
- **Soft Bone** (`#F4F4F4`): A cool-gray alternative surface used inside a handful of component subregions.
### Neutrals & Text
- **Ink Black** (`#141413`): Primary headline and body text color.
- **Charcoal** (`#262627`): A slightly softer black used for some text alternates.
- **Slate Gray** (`#696969`): Muted secondary text — eyebrow label alternative, disabled states, "Privacy Choices" bottom-row text.
- **Granite** (`#555555`) and **Graphite** (`#565656`): Deeper gray for inline body accents and link alternates.
- **Dust Taupe** (`#D1CDC7`): Very muted cream-gray used for disabled or "whisper" text (e.g., placeholder-like empty state labels). Low contrast on cream; use only for subdued content.
### Semantic & Accent
- **Link Blue** (`#3860BE`): A deep, slightly dusty blue used for inline links and informational callouts. Saturated enough to read as a link without being neon.
- **Priceless Red + Yellow**: The full-color Mastercard logo mark is the only place the brand's red and yellow appear together; they lock the identity to the page without acting as a UI palette.
### Gradient System
Mastercard uses no programmatic gradients in the core UI. The visual impression of "gradient" comes from two places:
- **Circular image portraits** where a warm-orange photo subject (a card, a sunflower, a beverage) fades to the cream canvas at its edge
- **Deep card shadows** on elevated content (`rgba(0,0,0,0.08) 0px 24px 48px`) that create a soft halo beneath pill-shaped media
## 3. Typography Rules
### Font Family
- **Primary**: `MarkForMC` — Mastercard's proprietary geometric sans. Every headline, body paragraph, button, nav link, and footer link on the page.
- **Secondary**: `MarkOffcForMC` — an "Official" cut used in a minority of contexts (legal text, some forms).
- **Fallback stack**: `SofiaSans, Arial, sans-serif` — Sofia Sans is a reasonable open-source stand-in; Arial is the final web-safe fallback.
### Hierarchy
| Role | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|--------|-------------|----------------|-------|
| H1 (hero) | 64px | 500 | 64px | -1.28px (-2%) | Set to `1:1` line-height for very tight vertical rhythm on multi-line hero |
| H2 (section) | 36px | 500 | 44px | -0.72px (-2%) | Used in ghost-watermark headline treatments and section titles |
| H3 (card title) | 24px | 500 | 28.8px (1.2) | -0.48px (-2%) | Titles inside service/solution cards |
| H4 (subhead) | 14px | 700 | 18.2px (1.3) | normal | Rarely used in marketing surfaces |
| Eyebrow (H5) | 14px | 700 | 14px | 0.56px (+4%) | Uppercase, paired with a tiny accent dot (e.g., "• SERVICES") |
| Body paragraph | 16px | 450 | 22.4px (1.4) | normal | The half-step 450 weight is MarkForMC's signature — softer than 500, firmer than 400 |
| Nav link / Button label | 16px | 500 | 16px | -0.48px (-3%) | Tight, compact, no text-transform |
| Footer link | 14px | 450 | ~20px | normal | Lighter weight on dark footer for airier density |
| Footer column header | 12–14px | 700 | 14px | 0.56px (+4%) | Uppercase, muted gray, short tracking |
### Principles
- **Weight 450 is load-bearing**. Most brands use 400/500/700; Mastercard uses 450 for body copy, which creates an unusually soft reading tone. Replacing it with 400 flattens the identity.
- **Tight negative tracking on headlines** (-2%) gives display text its editorial density — the words lock together rather than breathe.
- **Uppercase tracking only on the eyebrow scale** (14px / 700 / +4% tracking). Don't use uppercase anywhere else; no shouty section titles.
- **One-font system**. Resist the urge to add a second typeface for contrast. The contrast comes from scale, weight, and letter-spacing, not from a serif or display accent.
- **Line-height ratio drops with size**. H1 is 1:1, H3 is 1.2, body is 1.4. Tight display, comfortable reading.
### Note on Font Substitutes
MarkForMC is proprietary and licensed. When rebuilding a matching aesthetic without access to the original:
- **Sofia Sans** (Google Fonts) is the closest open-source match — it's already in Mastercard's declared fallback stack.
- **Inter** at weights 450/500/700 works as a generic stand-in; expect slightly taller x-height and looser letter shapes.
- **Neue Haas Grotesk** or **Geist** can approximate the geometric feel for commercial projects.
- Whichever substitute is used, preserve the **-2% letter-spacing on headlines** and the **450 body weight** (use `font-weight: 450` with variable fonts, or substitute `font-weight: 400` and tighten the letter-spacing by ~-0.5% to compensate).
## 4. Component Stylings
### Buttons
**Primary — Ink Pill**
- Background: Ink Black (`#141413`)
- Text: Canvas Cream (`#F3F0EE`) — not pure white
- Border: 1.5px solid Ink Black (same as bg, creates crisp edge)
- Radius: 20px
- Padding: 6px 24px
- Font: MarkForMC 16px / weight 500 / letter-spacing -0.32px
- Default: as above; solid warm-black pill on cream canvas
- Active / pressed: subtle inward-shrink or 2px offset (not a hover variant)
- Use for: all marketing CTAs in the page body ("Learn more", "Explore", "Discover")
**Secondary — Outlined Pill**
- Background: White (`#FFFFFF`)
- Text: Ink Black (`#141413`)
- Border: 1.5px solid Ink Black
- Radius: 20px
- Padding: 6px 24px
- Font: MarkForMC 16px / weight 450 / line-height 20.8px
- Default: white-on-cream pill with crisp ink outline
- Active / pressed: subtle compression
- Use for: secondary actions paired with a primary, or standalone utility CTAs
**Consent / Signal — Orange Pill**
- Background: Signal Orange (`#CF4500`)
- Text: White (`#FFFFFF`)
- Border: 0
- Radius: 24px
- Padding: 1px 30px (very tight vertical, wide horizontal)
- Font: MarkForMC 13px / weight 400 / letter-spacing 0.13px
- Default: as above; bright rust pill with white text
- Use for: cookie consent, privacy preference, and other legally-distinct confirmations. **Do not** use this orange for marketing CTAs — it reads as a compliance color.
**Satellite — Circular Micro-CTA**
- Background: White (`#FFFFFF`)
- Icon: Ink Black arrow (`→`) at ~20px
- Border: none
- Radius: 50% (perfect circle)
- Size: ~50–60px diameter
- Shadow: none or very subtle (the portrait's shadow carries the elevation)
- Default: docks onto the bottom-right edge of a circular portrait, protruding partway outside the portrait's circle
- Use for: the primary entry point into service/solution cards; always paired with a circular portrait
**Icon-Only Circle Button (carousel, play/pause)**
- Background: transparent or white
- Icon: 10–20px centered
- Border: 1px solid Ink Black (when on cream) or none (when over media)
- Radius: 50%
- Size: 40px diameter minimum for carousel controls; 80px for hero video play
- Use for: carousel pagination/play-pause, hero video play, search toggle
### Cards & Containers
**Hero Media Frame (Stadium)**
- Background: Dark video or full-bleed imagery (typically black `#000000` or `#2B2B2B` behind video)
- Radius: 40px all corners (creates a stadium shape on wide viewports)
- Width: ~full viewport minus ~48px gutter on each side
- Height: ~60–70% of viewport
- Shadow: none (sits directly on canvas)
- Corners: the extreme 40px radius on a media element is the most iconic Mastercard gesture — do not round less
**Service / Solution Portrait Card**
- Shape: Perfect circle (radius 50%) or ellipse (radius 999px / 1000px)
- Diameter: 260–340px desktop; ~220px mobile
- Image crop: square source, cropped to circle
- Attached element: White satellite circular CTA (see above) docked bottom-right, ~40% outside the portrait
- Eyebrow below: accent dot + uppercase label (e.g., "• SERVICES", "• SOLUTIONS")
- Title below: H3 (24px / weight 500 / -2% tracking), 1–2 lines max
- Decorative orbit: thin ~1px Light Signal Orange curved line spanning from this card outward to the next, implying connection
**Pill Carousel Card**
- Radius: 1000px (full pill) or 40px corners (rounded stadium)
- Width: ~40–60% of viewport
- Height: ~380–420px (portrait-pill orientation)
- Content: full-bleed photography with small overlaid chip labels
- Chip inside: White pill (~ 999px radius), Ink Black text, padding 8px 20px, used for category tags like "Story"
- Large inline CTA inside: Ink Pill button, oversized (padding 16px 40px, radius 40px)
**Ghost Watermark Text Block**
- Font: MarkForMC 72–128px / weight 500 / tight -2% tracking
- Color: Canvas Cream slightly darkened (`#E8E2DA` or similar — cream-on-cream)
- Position: layered behind portrait circles, bleeding off the viewport edge
- Purpose: sets section theme without competing with foreground copy
### Inputs & Forms
Minimal form surface on the marketing page. The search input in the nav header is:
- Initial state: a 48px circular button with a magnifier icon
- Expanded state: horizontal input field, border `1px solid` Ink Black at ~50% opacity, radius 999px, padding 12px 24px, white background
**Country/language selector (footer)**
- Background: Ink Black (same as footer)
- Text: White
- Border: 1px solid `rgba(255,255,255,0.4)`
- Radius: 999px (full pill)
- Icon: downward chevron on the right
### Navigation
**Floating Nav Pill (desktop)**
- Container: white-to-translucent-white pill floating below the very top of the viewport with a ~24px top margin
- Radius: 999px / 1000px (full pill)
- Padding: ~16px 40px internal
- Shadow: very soft (`rgba(0, 0, 0, 0.04) 0px 4px 24px 0px`) — just enough to lift it off the cream canvas
- Content: Mastercard logo left, primary link group center ("For you", "For business", "For the world", "For innovators", "News and trends"), search icon right
- Link spacing: ~48–56px gap between primary links
- Link style: Ink Black, weight 500, 16px, no underline, no pill surround until active
**Mobile Nav**
- The same pill shape but collapsed to: logo + hamburger menu button + search icon only
- Menu opens into a full-screen overlay with the primary links stacked vertically
### Image Treatment
- **Aspect ratios used**: 1:1 (all service portraits — cropped to circle), ~3:4 or ~4:5 (carousel pill cards), 16:9 or wider (hero video frame)
- **Full-bleed vs padded**: Hero is viewport-wide with gutters; service portraits are always centered in their column with generous whitespace around; footer imagery is rare
- **Masking**: Aggressive circular masking is the defining treatment — square source images are cropped to perfect circles of matching diameter. Never use rectangular service imagery.
- **Lazy loading**: Standard `loading="lazy"` with a soft blur-up transition from a cream-tinted placeholder, preserving the warm palette during load
### Decorative Orbital Lines
A signature motif: thin (~1–1.5px) single-weight curved lines in Light Signal Orange (`#F37338`) tracing arcs between circular portraits. These lines:
- Imply connection between service cards without literal arrows
- Span widths from ~200px up to full-viewport arcs
- Feel hand-drawn (subtle irregularity) rather than perfect CSS curves
- Appear only in sections with circular portrait content — never on pill sections, never in the footer
### Footer
- Background: Ink Black (`#141413`)
- Text: White
- Padding: 48px horizontal 100px / bottom 148px (very tall bottom space)
- Structure: large conversational H2 ("We're always here when you need us") left-aligned, then a 4-column link grid below
- Column headers: uppercase, muted, weight 700, letter-spacing +4%
- Link rows: white, weight 450, 14px; entries prefixed with a small icon (support bubble, card, map pin, question mark) for the "NEED HELP?" column
- External link marker: a small upper-right arrow (`↗`) after link text
- Bottom row (below a 1px white-at-opacity divider): copyright + privacy small-print + country-language pill dropdown + four social icons (LinkedIn, Facebook, X, YouTube)
## 5. Layout Principles
### Spacing System
- **Base unit**: 8px (confirmed by dembrandt extraction and computed styles)
- **Scale**: 8 / 16 / 24 / 32 / 48 / 64 / 96 / 128 (powers of 8)
- **Section vertical padding**: ~96–128px between major sections on desktop; ~48–64px on mobile
- **Card internal padding**: 32–40px on desktop, ~24px on mobile
- **Nav top margin**: ~24px from viewport top (the pill floats, doesn't touch)
### Grid & Container
- **Max content width**: ~1200–1280px centered, with ~48–100px horizontal gutter
- **Column pattern**: 12-column implied, but practical layouts use 2-up asymmetric (large headline left, supporting text right), 1-up full-bleed (hero, video), or staggered single-portrait placement (service cards sit in varying grid positions creating the "constellation" feel)
- **Footer grid**: 4 equal columns on desktop, collapses to single column accordion on mobile
### Whitespace Philosophy
Mastercard treats whitespace as structure, not absence. A typical service section has:
- A ghost headline occupying the top ~40% of the section (mostly empty cream)
- A single circular portrait positioned ~60% down, asymmetric to left or right
- ~300–500px of blank canvas between the portrait and the next section
This deliberate emptiness tells the eye "slow down, read one thing at a time" — the opposite of dense dashboard UIs.
### Border Radius Scale
| Radius | Use |
|--------|-----|
| 3–6px | Tiny decorative elements, cookie banner micro-chips |
| 20px | Primary and secondary body CTAs (the signature button radius) |
| 24px | Consent/orange pill buttons, modal inner chips |
| 40px | Hero media frames, large section container corners, H2 pill labels |
| 50% | Circular portraits, icon-only buttons, satellite CTAs |
| 99px / 999px / 1000px | Full pill shapes — navigation, carousel cards, footer country selector, primary inline chips |
The scale is unusual: most systems use 4/8/12/16. Mastercard skips those and commits to **either small (≤6), medium-large (20–40), or full-pill (99+)**. The middle ground of 8–12 is absent, which is why the UI feels either "precise and utility" or "soft and editorial" with no in-between.
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| 0 | No shadow | The default — 95% of surfaces sit directly on cream canvas |
| 1 | `rgba(0, 0, 0, 0.04) 0px 4px 24px 0px` | Floating nav pill — barely-there lift |
| 2 | `rgba(0, 0, 0, 0.08) 0px 24px 48px 0px` | Hero media frames, elevated cards — a soft large-radius halo rather than a hard drop |
| 3 | `rgba(0, 0, 0, 0.25) 0px 70px 110px 0px` | Rare; dramatic elevation on a feature tile |
### Shadow Philosophy
Mastercard uses shadows as **atmospheric cushioning**, not directional light. The Level 2 shadow has a 48px spread and only 8% opacity — it barely exists as dark pixels but creates a "the card is breathing above the canvas" feel. There are almost no hard-edged, tight shadows anywhere in the system. Border lines are preferred over shadows for functional delineation (form inputs, footer divider).
### Decorative Depth
- **Orbital arcs** (Light Signal Orange, ~1px): trace connective paths across sections
- **Ghost watermark headlines**: cream-on-cream text gives sections an almost-pressed-paper quality
- **Circle-image fade**: warm-toned photography at the edge of circular portraits dissolves into the canvas, implying soft atmospheric depth
## 7. Do's and Don'ts
### Do
- Use Canvas Cream (`#F3F0EE`) as the default body background — never pure white
- Mask service/feature imagery as perfect circles, not rectangles or rounded rectangles
- Attach a white satellite CTA to the bottom-right of each circular portrait
- Set headlines in MarkForMC weight 500 with -2% letter-spacing
- Use weight 450 (not 400) for body paragraphs
- Keep primary CTAs as Ink Black pills (20px radius) with cream text
- Use Signal Orange only on consent, legal, or compliance actions
- Float the nav as a rounded white pill below the viewport top, not flush at y=0
- Build page rhythm from three surface tones: canvas cream → lifted cream → ink footer
- Use thin Light Signal Orange arcs between service cards to imply connection
### Don't
- Don't use pure white as a page background — it breaks the warm editorial tone
- Don't round image frames at 8–16px — Mastercard either uses full-pill, 40px, or full-circle. In-between radii look generic
- Don't use Signal Orange for marketing CTAs — it reads as cookie-consent orange and dilutes the legal color signal
- Don't mix typefaces — no serif accent, no script, no secondary display font
- Don't crowd the nav with more than six top-level links — the pill is meant to feel airy
- Don't drop hard shadows — all elevation should use 48px+ spread and ≤10% opacity
- Don't use uppercase for anything larger than the 14px eyebrow label
- Don't omit the tiny accent dot before eyebrow labels — it's the identity
- Don't place circular portraits on a grid — their magic comes from asymmetric placement
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | ≤ 767px | Nav pill shows logo + menu + search only; primary links hide behind hamburger; service portraits stack single-column centered; hero headline drops from 64px to ~40px; footer columns collapse into a vertical accordion |
| Tablet | 768–1023px | Nav pill shows 2–3 primary links truncated; service portraits arrange 2-up; hero headline ~48px |
| Desktop | ≥ 1024px | Full nav with 5 primary links centered; service portraits asymmetrically placed with decorative orbital lines; hero headline 64px |
| Wide | ≥ 1440px | Content max-width caps at ~1280px; gutters grow symmetrically; orbital lines extend further |
### Touch Targets
All interactive elements comfortably exceed 44×44px. The satellite CTA (circle + arrow) is ~50–60px. The nav pill buttons are ~48px tall. Mobile hamburger and search are 48×48px. No link or button drops below 40px in any breakpoint.
### Collapsing Strategy
- **Nav**: full pill → compact pill with hamburger. Pill shape is preserved across breakpoints — always rounded, always floating.
- **Service grid**: asymmetric constellation → 2-up → 1-up stack. Orbital arcs are removed on mobile (they only work with asymmetric placement).
- **Spacing**: section vertical padding compresses from 128px to 48px on mobile.
- **Content**: two-column hero (headline left / supporting text right) becomes stacked (headline on top, supporting text below).
- **Footer**: 4 columns → 1 column accordion with chevron toggles per section.
### Image Behavior
Circular portraits scale proportionally (maintaining the perfect circle at every size). Hero video frames maintain their 40px radius at every breakpoint, but the frame itself shrinks with the viewport. Lazy loading is standard with a cream-tinted blur-up placeholder, preserving the palette during load.
## 9. Agent Prompt Guide
### Quick Color Reference
- Primary CTA: "Ink Black (`#141413`) — the warm near-black used for primary pill buttons and footer"
- Background: "Canvas Cream (`#F3F0EE`) — warm putty body canvas, never pure white"
- Lifted surface: "Lifted Cream (`#FCFBFA`) — one step lighter than canvas for nested sections"
- Heading text: "Ink Black (`#141413`)"
- Body text: "Ink Black (`#141413`) at weight 450"
- Muted text: "Slate Gray (`#696969`)"
- Signal / Consent: "Signal Orange (`#CF4500`) — reserve for cookie consent and legal actions"
- Accent arc: "Light Signal Orange (`#F37338`) — orbital decorative lines only"
- Border / Outline: "Ink Black at 1.5px for pill buttons; 1px at low opacity elsewhere"
- Footer: "Ink Black (`#141413`) with White text"
### Example Component Prompts
- "Create a circular portrait card 300px in diameter, with a square photograph cropped to a perfect circle. Attach a 56px white satellite button with a dark arrow icon at the bottom-right, so it protrudes ~40% outside the portrait. Below the portrait, add an eyebrow label with a Light Signal Orange dot and uppercase 'SERVICES' text in MarkForMC weight 700 at 14px. Below the eyebrow, set a 24px / weight 500 title in Ink Black."
- "Design a primary CTA button: Ink Black (`#141413`) background, Canvas Cream (`#F3F0EE`) text, 20px border-radius, 6px vertical and 24px horizontal padding, MarkForMC font at 16px weight 500 with -2% letter-spacing."
- "Build a floating navigation pill: white background with `rgba(0, 0, 0, 0.04) 0px 4px 24px 0px` shadow, 999px border-radius, ~16px vertical and 40px horizontal internal padding. Position it 24px below the viewport top, centered, with the Mastercard logo at the left, five primary links centered with 48px gap, and a circular 48px search button at the right."
- "Create a hero media frame: 40px border-radius on all corners, full viewport width minus 48px gutters, ~60% viewport height, dark background for video content. Place it directly on the cream canvas with no shadow."
- "Design a footer: Ink Black (`#141413`) background, white text, 4-column link grid with uppercase muted column headers at 14px weight 700 +4% tracking. Include a large conversational H2 above the grid, a 1px white-at-30%-opacity horizontal divider below, and a bottom row with copyright, legal small-print links, a pill-shaped country selector, and four social icons."
### Iteration Guide
When refining existing screens generated with this design system:
1. Focus on ONE component at a time — don't redesign multiple surfaces in parallel
2. Reference specific color names AND hex codes from this document
3. Use natural language ("warm putty cream", "stadium pill", "circular portrait with satellite CTA") alongside technical values
4. Describe the desired "feel" (editorial, soft, institutional) alongside specific measurements
5. When in doubt, reach for one of three radii: 20px (buttons), 40px (hero/stadium), or 999px (pill/nav)
6. Default backgrounds to Canvas Cream (`#F3F0EE`), not white — this single change shifts the entire mood toward Mastercard
### Known Gaps
- The live page uses MarkForMC, a proprietary licensed typeface. Sofia Sans is the closest open-source substitute and is listed in Mastercard's own fallback stack.
- Tablet breakpoint specifics (768–1023px) were inferred from desktop and mobile captures; intermediate layouts may vary per section.
- The exact "whisper" cream tone used for ghost-watermark headlines behind circular portraits reads between `#E8E2DA` and `#D1CDC7` in captures; the precise value varies per section.
- Third-party consent orange (`#CF4500`) is Mastercard's documented consent signal and should not be confused with any marketing CTA color.
- The Mastercard logo mark (red `#EB001B` + yellow `#F79E1B`) is a brand asset, not a UI palette entry.

# Design System Inspired by Meta (Store)
> Category: E-Commerce & Retail
> Tech retail store. Photography-first, binary light/dark surfaces, Meta Blue CTAs.
## 1. Visual Theme & Atmosphere
The Meta Store is a product-forward retail experience built to sell hardware — Quest VR headsets, Ray-Ban Meta smart glasses, and accessories. The design walks a tightrope between consumer electronics showroom and lifestyle editorial, deploying cinematic product photography against expansive white canvas to create a gallery-like sense of aspiration. Every design decision serves the merchandise: generous negative space frames hero product shots like museum pieces, while alternating light and dark surface sections create a visual rhythm that mimics the experience of walking through a physical retail space.
The "Dolly" design system (Meta's internal name for the store layer) sits atop the broader FDS (Facebook Design System) foundation, inheriting its gray scale and semantic tokens while overlaying its own product-focused palette. The result is a system that feels distinctly Meta — the custom Optimistic typeface brings warmth and approachability to what could otherwise be cold tech retail — yet flexible enough to showcase wildly different product lines (from VR headsets to fashion eyewear) without feeling disjointed. The surface strategy is binary: pure white for browsing and information, rich dark for immersive product moments.
The store's visual hierarchy is ruthlessly simple. Photography does the heavy lifting, supported by short, punchy headlines in Optimistic Medium and body text that stays brief and scannable. Calls to action are pill-shaped, unmistakable, and always Meta Blue. There is no visual noise, no decoration for decoration's sake — every element either sells or navigates.
**Key Characteristics:**
- Photography-first retail design where products are the visual heroes, not UI
- Binary surface strategy: pure white for information, deep dark for immersive product moments
- Pill-shaped CTAs in saturated blue create unmistakable action points
- Optimistic VF typeface with OpenType ss01/ss02 features brings geometric warmth
- Generous whitespace frames products like gallery exhibits
- 8px spacing grid with disciplined vertical rhythm
- Alternating light/dark sections create a "walkthrough" retail cadence

- **Blue Infinity Gradient**: The Meta symbol uses a blue-to-teal gradient on brand materials, though the store uses flat blue
- **Shadow Alpha Scale**: 0.05, 0.10, 0.15, 0.20, 0.30, 0.40, 0.50, 0.60, 0.80 — both black and white alpha ramps for layered transparency
## 3. Typography Rules
### Font Family
**Primary:** Optimistic VF (variable font by Dalton Maag, commissioned by Meta)
- Fallbacks: Montserrat, Helvetica, Arial, Noto Sans
- OpenType features: `"ss01", "ss02"` — stylistic sets that activate Meta-specific alternate glyphs
- Variable font with continuous weight axis (observed: 300, 400, 500, 700)
**Secondary:** Helvetica
- Fallbacks: Arial
- Used for small utility text (12px footer links, legal copy)
### Hierarchy
| Role | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|--------|-------------|----------------|-------|
| Display 1 | 64px | 500 (Medium) | 1.16 | — | Hero headlines on desktop, ss01+ss02 |
| Display 2 | 48px | 500 (Medium) | 1.17 | — | Section heroes, product titles |
| Heading 1 | 36px | 500 (Medium) | 1.28 | — | Major section headings |
| Heading 2 | 28px | 300 (Light) | 1.21 | — | Subheadings, lighter feel |
| Heading 3 | 18px | 700 (Bold) | 1.44 | — | Card titles, bold callouts, ss01+ss02 |
| Body | 18px | 400 (Regular) | 1.44 | — | Product descriptions, body copy |
| Body Compact | 16px | 500 (Medium) | 1.50 | -0.16px | Navigation links, UI labels |
| Caption Bold | 14px | 700 (Bold) | 1.43 | — | Emphasized labels, price text |
| Caption | 14px | 400 (Regular) | 1.43 | -0.14px | Secondary labels, metadata |
| Small | 12px | 400 (Regular) | 1.33 | — | Footer links, legal text, timestamps |
| Button | 14px | 400 (Regular) | 1.43 | -0.14px | Button label text |
### Principles
Optimistic VF is the cornerstone of Meta's typographic identity — a humanist sans-serif with geometric underpinnings that strikes a balance between Silicon Valley precision and consumer warmth. The "ss01" and "ss02" stylistic sets introduce alternate glyphs that give headlines a distinctive Meta character. Weight 500 (Medium) dominates headlines, creating a presence that commands without shouting, while the unexpected use of weight 300 (Light) at 28px adds an airy, editorial quality to subheadings. Negative letter-spacing at smaller sizes (-0.14px to -0.16px) tightens the optical rhythm for UI elements, keeping the reading experience crisp and efficient.

- **Portal sections**: Teal-blue palette (`#C8E4E8`, `#ADD4E0`), navy accents (`#1B365D`)
## 5. Layout Principles
### Spacing System
Base unit: 8px
| Token | Value | Use |
|-------|-------|-----|
| space-1 | 1px | Hairline borders |
| space-2 | 4px | Tight internal padding |
| space-3 | 8px | Base unit, icon gaps |
| space-4 | 10px | Card horizontal padding |
| space-5 | 12px | Button icon spacing, tight margins |
| space-6 | 14px | Caption line height spacing |
| space-7 | 16px | Standard paragraph spacing, nav padding |
| space-8 | 18px | Body text vertical rhythm |
| space-9 | 24px | Card section spacing, grid gaps |
| space-10 | 32px | Section content padding |
| space-11 | 40px | Major content block spacing |
| space-12 | 48px | Section vertical padding (compact) |
| space-13 | 64px | Section vertical padding (standard) |
| space-14 | 80px | Hero section padding, large section gaps |
### Grid & Container
- Max container width: ~1440px, centered with auto margins
- Product grid: 3-column on desktop, 2-column on tablet, 1-column on mobile
- Feature grid: 2-column split (image + content), stacks on mobile
- Grid gap: 24px between cards, 16px on mobile
- Page horizontal padding: 24-40px depending on breakpoint
### Whitespace Philosophy
Whitespace is the store's primary luxury signifier. Sections breathe with 64-80px vertical padding, creating a sense of unhurried browsing. Product images float in generous negative space rather than being crammed edge-to-edge. This restrained spacing communicates premium positioning — the visual equivalent of wide aisles in a high-end retail store.
### Border Radius Scale
| Value | Context |
|-------|---------|
| 8px | Inputs, small UI elements, glimmer placeholders |
| 20px | Cards (--card-corner-radius) |
| 24px | Feature cards, product highlight areas, ghost buttons |
| 100px | Pill buttons, tags, badges (fully rounded) |
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat | No shadow, background differentiation only | Default cards, sections |
| Level 1 | `0 2px 4px 0 rgba(0,0,0,0.1)` | Subtle lift for interactive cards |
| Level 2 | `0 12px 28px 0 rgba(0,0,0,0.2), 0 2px 4px 0 rgba(0,0,0,0.1)` | Elevated cards, dropdowns |
| Overlay | `rgba(0,0,0,0.6)` full-screen | Modal/lightbox backdrop |
| Inset | `rgba(255,255,255,0.5)` inset | Inner glow on glass-effect surfaces |
The Meta Store favors a primarily flat elevation model. Most surface differentiation comes from background color shifts (white → soft gray → dark) rather than shadows. When shadows appear, they are soft, diffused, and use the dual-shadow pattern (a large blurred shadow for ambient light + a small sharp shadow for direct light). This creates a physically plausible depth feel without heavy visual weight.
### Decorative Depth
- **Frosted glass nav**: `rgba(241, 244, 247, 0.8)` background with backdrop-filter blur, creating a translucent navigation bar
- **Dark section gradient**: `linear-gradient(rgba(0,0,0,0), rgba(0,0,0,0.6))` overlay on product photography for text legibility
- **Glimmer loading states**: Pulsating opacity animation (0.25 → 1.0) on `#979A9F` base color with 8px radius, 1000ms steps timing — used for skeleton screens during product image loading
## 7. Do's and Don'ts
### Do
- Use pill-shaped (100px radius) buttons for all primary and secondary CTAs
- Let product photography dominate — make images the visual hero of every section
- Alternate between light and dark surface sections to create visual rhythm
- Use Optimistic VF with ss01 and ss02 features for all display text
- Keep body copy brief and scannable — this is retail, not editorial
- Use the dual-shadow pattern (ambient + direct) when elevation is needed
- Apply Meta Blue (`#0064E0`) exclusively for actionable elements
- Use generous whitespace (64-80px section padding) to convey premium feel
- Apply gradient overlays on dark photography when placing text over images
- Use the semantic color tokens (success, error, warning) consistently for status communication
### Don't
- Don't use sharp corners (< 8px radius) — the Meta Store is all smooth curves
- Don't mix product-specific accents (Ray-Ban Red with Quest Purple in the same section)
- Don't add decorative borders or ornamental dividers — dividers are functional only
- Don't place important text directly on photography without a gradient scrim
- Don't use weight 300 for anything smaller than 28px — it becomes too thin
- Don't use Facebook Blue (`#1877F2`) as a primary CTA color — use Meta Blue (`#0064E0`) instead
- Don't crowd product images — maintain generous padding around all photography
- Don't use more than 2 levels of text hierarchy in a single card
- Don't add drop shadows to cards in dark sections — rely on border and color separation
- Don't use long paragraphs — limit to 2-3 lines of body copy per block
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | <768px | Single column, hamburger nav, hero text shrinks to 36px, full-width product cards, 48px section padding |
| Tablet | 768-1024px | 2-column product grid, compact nav, hero text at 48px |
| Desktop | 1024-1440px | 3-column product grid, full horizontal nav, hero text at 64px, 80px section padding |
| Large Desktop | >1440px | Max-width container (1440px) centered, increased horizontal margins |
### Touch Targets
- Minimum touch target: 44x44px (WCAG AAA compliant)
- Mobile button height: minimum 44px with 10px vertical padding
- Nav hamburger icon: 48x48px touch area
- Product card tappable area: full card surface
### Collapsing Strategy
- **Navigation**: Horizontal links collapse to hamburger menu below 768px; CTA button remains visible
- **Product grids**: 3-col → 2-col at 1024px → 1-col at 768px
- **Hero sections**: Display text scales from 64px → 48px → 36px; CTA buttons stack vertically on mobile
- **Feature sections**: 2-column (image + text) → full-width stacked below 768px, image on top
- **Section padding**: 80px → 64px → 48px → 32px as viewport narrows
- **Card radius**: Remains consistent at 20-24px across all breakpoints
### Image Behavior
- Responsive images via srcset with multiple resolutions
- WebP format with progressive JPEG fallback
- Hero images: full-bleed on mobile, contained on desktop
- Product grid images: maintain aspect ratio, scale proportionally
- Art direction: hero crop changes between desktop (wide cinematic) and mobile (tighter product focus)
- Lazy loading with glimmer skeleton (pulsating gray placeholder) during load
## 9. Agent Prompt Guide
### Quick Color Reference
- Primary CTA: Meta Blue (`#0064E0`)
- Background: White (`#FFFFFF`)
- Heading text: Dark Charcoal (`#1C2B33`)
- Body text: Slate Gray (`#5D6C7B`)
- Border/divider: Divider Gray (`#DEE3E9`)
- Secondary surface: Soft Gray (`#F1F4F7`)
- Dark sections: Near Black (`#1C1E21`)
### Example Component Prompts
- "Create a product hero section with a full-width cinematic image, `linear-gradient(rgba(0,0,0,0), rgba(0,0,0,0.6))` text overlay, Optimistic-style 64px/500 white headline, and a Meta Blue (`#0064E0`) pill button (100px radius, 10px 22px padding)"
- "Design a 3-column product card grid with 20px rounded corners, white backgrounds, edge-to-edge product images at top, 18px/400 body text in Slate Gray (`#5D6C7B`), and 24px grid gap"
- "Build a sticky navigation bar with white background, `rgba(241, 244, 247, 0.8)` frosted glass effect, 16px/500 dark text links, and a right-aligned Meta Blue pill CTA"
- "Create a dark product showcase section with `#1C1E21` background, white 48px/500 headline, `#5D6C7B` body text, and a secondary outlined pill button with `rgba(10, 19, 23, 0.12)` border"
- "Design a feature comparison grid with Soft Gray (`#F1F4F7`) background, 24px rounded cards, Meta Blue checkmark icons, and 14px/700 bold labels"
### Iteration Guide
When refining existing screens generated with this design system:
1. Focus on ONE component at a time
2. Reference specific color names and hex codes from this document
3. Use natural language descriptions, not CSS values — "pill-shaped Meta Blue button" not "border-radius: 100px; background: #0064E0"
4. Describe the desired "feel" alongside specific measurements — "generous whitespace like a gallery" means 64-80px section padding
5. For dark sections, specify which product context (Quest dark `#181A1B`, pure black `#000000`, or standard dark `#1C1E21`)
6. Always specify the Optimistic VF weight explicitly (300, 400, 500, or 700) — each creates a dramatically different feel

- Do not introduce off-palette colors when an existing token can solve the problem.
- Do not flatten hierarchy by using the same type size/weight for all text.
- Do not add decorative effects that reduce readability or accessibility.
- Do not mix unrelated visual metaphors in the same interface.

# Design System Inspired by MiniMax
> Category: AI & LLM
> AI model provider. Bold dark interface with neon accents.
## 1. Visual Theme & Atmosphere
MiniMax's website is a clean, product-showcase platform for a Chinese AI technology company that bridges consumer-friendly appeal with technical credibility. The design language is predominantly white-space-driven with a light, airy feel — pure white backgrounds (`#ffffff`) dominate, letting colorful product cards and AI model illustrations serve as the visual anchors. The overall aesthetic sits at the intersection of Apple's product marketing clarity and a playful, rounded design language that makes AI technology feel approachable.
The typography system is notably multi-font: DM Sans serves as the primary UI workhorse, Outfit handles display headings with geometric elegance, Poppins appears for mid-tier headings, and Roboto handles data-heavy contexts. This variety reflects a brand in rapid growth — each font serves a distinct communicative purpose rather than competing for attention. The hero heading at 80px weight 500 in both DM Sans and Outfit with a tight 1.10 line-height creates a bold but not aggressive opening statement.
What makes MiniMax distinctive is its pill-button geometry (9999px radius) for navigation and primary actions, combined with softer 8px–24px radiused cards for product showcases. The product cards themselves are richly colorful — vibrant gradients in pink, purple, orange, and blue — creating a "gallery of AI capabilities" feel. Against the white canvas, these colorful cards pop like app icons on a phone home screen, making each AI model/product feel like a self-contained creative tool.
**Key Characteristics:**
- White-dominant layout with colorful product card accents
- Multi-font system: DM Sans (UI), Outfit (display), Poppins (mid-tier), Roboto (data)
- Pill buttons (9999px radius) for primary navigation and CTAs
- Generous rounded cards (20px–24px radius) for product showcases
- Brand blue spectrum: from `#1456f0` (brand-6) through `#3b82f6` (primary-500) to `#60a5fa` (light)
- Brand pink (`#ea5ec1`) as secondary accent
- Near-black text (`#222222`, `#18181b`) on white backgrounds
- Purple-tinted shadows (`rgba(44, 30, 116, 0.16)`) creating subtle brand-colored depth
- Dark footer section (`#181e25`) with product/company links

- **Mid-tier**: `Poppins`
- **Data/Technical**: `Roboto`, with fallbacks: `Helvetica Neue, Helvetica, Arial`
### Hierarchy
| Role | Font | Size | Weight | Line Height | Notes |
|------|------|------|--------|-------------|-------|
| Display Hero | DM Sans / Outfit | 80px (5.00rem) | 500 | 1.10 (tight) | Hero headlines |
| Section Heading | Outfit | 31px (1.94rem) | 600 | 1.50 | Feature section titles |
| Section Heading Alt | Roboto / DM Sans | 32px (2.00rem) | 600 | 0.88 (tight) | Compact headers |
| Card Title | Outfit | 28px (1.75rem) | 500–600 | 1.71 (relaxed) | Product card headings |
| Sub-heading | Poppins | 24px (1.50rem) | 500 | 1.50 | Mid-tier headings |
| Feature Label | Poppins | 18px (1.13rem) | 500 | 1.50 | Feature names |
| Body Large | DM Sans | 20px (1.25rem) | 500 | 1.50 | Emphasized body |
| Body | DM Sans | 16px (1.00rem) | 400–500 | 1.50 | Standard body text |
| Body Bold | DM Sans | 16px (1.00rem) | 700 | 1.50 | Strong emphasis |
| Nav/Link | DM Sans | 14px (0.88rem) | 400–500 | 1.50 | Navigation, links |
| Button Small | DM Sans | 13px (0.81rem) | 600 | 1.50 | Compact buttons |
| Caption | DM Sans / Poppins | 13px (0.81rem) | 400 | 1.70 (relaxed) | Metadata |
| Small Label | DM Sans | 12px (0.75rem) | 500–600 | 1.25–1.50 | Tags, badges |
| Micro | DM Sans / Outfit | 10px (0.63rem) | 400–500 | 1.50–1.80 | Tiny annotations |
### Principles
- **Multi-font purpose**: DM Sans = UI workhorse (body, nav, buttons); Outfit = geometric display (headings, product names); Poppins = friendly mid-tier (sub-headings, features); Roboto = technical/data contexts.
- **Universal 1.50 line-height**: The overwhelming majority of text uses 1.50 line-height, creating a consistent reading rhythm regardless of font or size. Exceptions: display (1.10 tight) and some captions (1.70 relaxed).
- **Weight 500 as default emphasis**: Most headings use 500 (medium) rather than bold, creating a modern, approachable tone. 600 for section titles, 700 reserved for strong emphasis.
- **Compact hierarchy**: The size scale jumps from 80px display straight to 28–32px section, then 16–20px body — a deliberate compression that keeps the visual hierarchy feeling efficient.
## 4. Component Stylings
### Buttons
**Pill Primary Dark**
- Background: `#181e25`

- Shadow: `rgba(44, 30, 116, 0.16) 0px 0px 15px` (brand purple glow)
- Content: Product name, model version, descriptive text
- Each card has its own color palette matching the product identity
### AI Product Cards (Matrix)
- Background: white with subtle shadow
- Radius: 13px–16px
- Shadow: `rgba(0, 0, 0, 0.08) 0px 4px 6px`
- Icon/illustration centered above product name
- Product name in DM Sans 14–16px weight 500
### Links
- **Primary**: `#18181b` or `#181e25`, underline on dark text
- **Secondary**: `#8e8e93`, muted for less emphasis
- **On Dark**: `rgba(255, 255, 255, 0.8)` for footer and dark sections
### Navigation
- Clean horizontal nav on white background
- MiniMax logo left-aligned (red accent in logo)
- DM Sans 14px weight 500 for nav items
- Pill-shaped active indicators (9999px radius)
- "Login" text link, minimal right-side actions
- Sticky header behavior
## 5. Layout Principles
### Spacing System
- Base unit: 8px
- Scale: 1px, 2px, 4px, 6px, 8px, 10px, 11px, 14px, 16px, 24px, 32px, 40px, 50px, 64px, 80px
### Grid & Container
- Max content width centered on page
- Product card grids: horizontal scroll or 3–4 column layout
- Full-width white sections with contained content
- Dark footer at full-width
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | <768px | Single column, stacked cards |
| Tablet | 768–1024px | 2-column grids |
| Desktop | >1024px | Full layout, horizontal card scrolls |
### Whitespace Philosophy
- **Gallery spacing**: Products are presented like gallery items with generous white space between cards, letting each AI model breathe as its own showcase.
- **Section rhythm**: Large vertical gaps (64px–80px) between major sections create distinct "chapters" of content.
- **Card breathing**: Product cards use internal padding of 16px–24px with ample whitespace around text.
### Border Radius Scale
- Minimal (4px): Small tags, micro badges
- Standard (8px): Buttons, small cards
- Comfortable (11px–13px): Medium cards, panels
- Generous (16px–20px): Large product cards
- Large (22px–24px): Hero product cards, major containers
- Pill (30px–32px): Badge pills, rounded panels
- Full (9999px): Buttons, nav tabs
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | White background, text blocks |
| Subtle (Level 1) | `rgba(0, 0, 0, 0.08) 0px 4px 6px` | Standard cards, containers |
| Ambient (Level 2) | `rgba(0, 0, 0, 0.08) 0px 0px 22.576px` | Soft glow around elements |
| Brand Glow (Level 3) | `rgba(44, 30, 116, 0.16) 0px 0px 15px` | Featured product cards |
| Elevated (Level 4) | `rgba(36, 36, 36, 0.08) 0px 12px 16px -4px` | Lifted cards, hover states |
**Shadow Philosophy**: MiniMax uses a distinctive purple-tinted shadow (`rgba(44, 30, 116, ...)`) for featured elements, creating a subtle brand-color glow that connects the shadow system to the blue brand identity. Standard shadows use neutral black but at low opacity (0.08), keeping everything feeling light and airy. The directional shadow variant (6.5px offset) adds dimensional interest to hero product cards.
## 7. Do's and Don'ts
### Do
- Use white as the dominant background — let product cards provide the color
- Apply pill radius (9999px) for navigation tabs and toggle buttons
- Use generous border radius (20px–24px) for product showcase cards
- Employ the purple-tinted shadow for featured/hero product cards
- Keep body text at DM Sans weight 400–500 — heavier weights for buttons only
- Use Outfit for display headings, DM Sans for everything functional
- Maintain the universal 1.50 line-height across body text
- Let colorful product illustrations/gradients serve as the primary visual interest
### Don't
- Don't add colored backgrounds to main content sections — white is structural
- Don't use sharp corners (0–4px radius) on product cards — the rounded aesthetic is core
- Don't apply the brand pink (`#ea5ec1`) to text or buttons — it's for logo and decorative accents only
- Don't mix more than one display font per section (Outfit OR Poppins, not both)
- Don't use weight 700 for headings — 500–600 is the range, 700 is reserved for strong emphasis in body text
- Don't darken shadows beyond 0.16 opacity — the light, airy feel requires restraint
- Don't use Roboto for headings — it's the data/technical context font only
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | <768px | Single column, stacked product cards, hamburger nav |
| Tablet | 768–1024px | 2-column product grids, condensed spacing |
| Desktop | >1024px | Full horizontal card layouts, expanded spacing |
### Collapsing Strategy
- Hero: 80px → responsive scaling to ~40px on mobile
- Product card grid: horizontal scroll → 2-column → single column stacked
- Navigation: horizontal → hamburger menu
- Footer: multi-column → stacked sections
- Spacing: 64–80px gaps → 32–40px on mobile
## 9. Agent Prompt Guide
### Quick Color Reference
- Background: `#ffffff` (primary), `#181e25` (dark/footer)
- Text: `#222222` (primary), `#45515e` (secondary), `#8e8e93` (muted)
- Brand Blue: `#1456f0` (brand), `#3b82f6` (primary-500), `#2563eb` (hover)
- Brand Pink: `#ea5ec1` (accent only)
- Borders: `#e5e7eb`, `#f2f3f5`
### Example Component Prompts
- "Create a hero section on white background. Headline at 80px Outfit weight 500, line-height 1.10, near-black (#222222) text. Sub-text at 16px DM Sans weight 400, line-height 1.50, #45515e. Dark CTA button (#181e25, 8px radius, 11px 20px padding, white text)."
- "Design a product card grid: white cards with 20px border-radius, shadow rgba(44,30,116,0.16) 0px 0px 15px. Product name at 28px Outfit weight 600. Internal gradient background for the product illustration area."
- "Build navigation bar: white background, DM Sans 14px weight 500 for links, #18181b text. Pill-shaped active tab (9999px radius, rgba(0,0,0,0.05) background). MiniMax logo left-aligned."
- "Create an AI product matrix: 4-column grid of cards with 13px radius, subtle shadow rgba(0,0,0,0.08) 0px 4px 6px. Centered icon above product name in DM Sans 16px weight 500."
- "Design footer on dark (#181e25) background. Product links in DM Sans 14px, rgba(255,255,255,0.8). Multi-column layout."
### Iteration Guide
1. Start with white — color comes from product cards and illustrations only
2. Pill buttons (9999px) for nav/tabs, standard radius (8px) for CTA buttons
3. Purple-tinted shadows for featured cards, neutral shadows for everything else
4. DM Sans handles 70% of text — Outfit is display-only, Poppins is mid-tier only
5. Keep weights moderate (500–600 for headings) — the brand tone is confident but approachable
6. Large radius cards (20–24px) for products, smaller radius (8–13px) for UI elements

# Design System Inspired by Mintlify
> Category: Productivity & SaaS
> Documentation platform. Clean, green-accented, reading-optimized.
## 1. Visual Theme & Atmosphere
Mintlify's website is a study in documentation-as-product design — a white, airy, information-rich surface that treats clarity as its highest aesthetic value. The page opens with a luminous white (`#ffffff`) background, near-black (`#0d0d0d`) text, and a signature green brand accent (`#18E299`) that signals freshness and intelligence without dominating the palette. The overall mood is calm, confident, and engineered for legibility — a design system that whispers "we care about your developer experience" in every pixel.
The Inter font family carries the entire typographic load. At display sizes (40–64px), it uses tight negative letter-spacing (-0.8px to -1.28px) and semibold weight (600), creating headlines that feel focused and compressed like well-written documentation headers. Body text at 16–18px with 150% line-height provides generous reading comfort. Geist Mono appears exclusively for code and technical labels — uppercase, tracked-out, small — the voice of the terminal inside the marketing page.
What distinguishes Mintlify from other documentation platforms is its atmospheric gradient hero. A soft, cloud-like green-to-white gradient wash behind the hero content creates a sense of ethereal intelligence — documentation that floats above the noise. Below the hero, the page settles into a disciplined alternation of white sections separated by subtle 5% opacity borders. Cards use generous padding (24px+) with large radii (16px–24px) and whisper-thin borders, creating containers that feel open rather than boxed.
**Key Characteristics:**
- Inter with tight negative tracking at display sizes (-0.8px to -1.28px) — compressed yet readable
- Geist Mono for code labels: uppercase, 12px, tracked-out, the terminal voice
- Brand green (`#18E299`) used sparingly — CTAs, hover states, focus rings, and accent touches
- Atmospheric gradient hero with cloud-like green-white wash
- Ultra-round corners: 16px for containers, 24px for featured cards, full-round (9999px) for buttons and pills
- Subtle 5% opacity borders (`rgba(0,0,0,0.05)`) creating barely-there separation
- 8px base spacing system with generous section padding (48px–96px)
- Clean white canvas — no gray backgrounds, no color sections, depth through borders and whitespace alone
## 2. Color Palette & Roles
### Primary
- **Near Black** (`#0d0d0d`): Primary text, headings, dark surfaces. Not pure black — the micro-softness improves reading comfort.
- **Pure White** (`#ffffff`): Page background, card surfaces, input backgrounds.
- **Brand Green** (`#18E299`): The signature accent — CTAs, links on hover, focus rings, brand identity.
### Secondary Accents
- **Brand Green Light** (`#d4fae8`): Tinted green surface for badges, hover states, subtle backgrounds.
- **Brand Green Deep** (`#0fa76e`): Darker green for text on light-green badges, hover states on brand elements.
- **Warm Amber** (`#c37d0d`): Warning states, caution badges — `--twoslash-warn-bg`.
- **Soft Blue** (`#3772cf`): Tag backgrounds, informational annotations — `--twoslash-tag-bg`.
- **Error Red** (`#d45656`): Error states, destructive actions — `--twoslash-error-bg`.
### Neutral Scale
- **Gray 900** (`#0d0d0d`): Primary heading text, nav links.
- **Gray 700** (`#333333`): Secondary text, descriptions, body copy.
- **Gray 500** (`#666666`): Tertiary text, muted labels.
- **Gray 400** (`#888888`): Placeholder text, disabled states, code annotations.
- **Gray 200** (`#e5e5e5`): Borders, dividers, card outlines.
- **Gray 100** (`#f5f5f5`): Subtle surface backgrounds, hover states.
- **Gray 50** (`#fafafa`): Near-white surface tint.
### Interactive
- **Link Default** (`#0d0d0d`): Links match text color, relying on underline/context.
- **Link Hover** (`#18E299`): Brand green on hover — `var(--color-brand)`.
- **Focus Ring** (`#18E299`): Brand green focus outline for inputs and interactive elements.
### Surface & Overlay
- **Card Background** (`#ffffff`): White cards on white background, separated by borders.
- **Border Subtle** (`rgba(0,0,0,0.05)`): 5% black opacity borders — the primary separation mechanism.
- **Border Medium** (`rgba(0,0,0,0.08)`): Slightly stronger borders for interactive elements.
- **Input Border Focus** (`var(--color-brand)`): Green ring on focused inputs.
### Shadows & Depth
- **Card Shadow** (`rgba(0,0,0,0.03) 0px 2px 4px`): Barely-there ambient shadow for subtle lift.
- **Button Shadow** (`rgba(0,0,0,0.06) 0px 1px 2px`): Micro-shadow for button depth.
- **No heavy shadows**: Mintlify relies on borders, not shadows, for depth.
## 3. Typography Rules
### Font Family
- **Primary**: `Inter`, with fallback: `Inter Fallback, system-ui, -apple-system, sans-serif`
- **Monospace**: `Geist Mono`, with fallback: `Geist Mono Fallback, ui-monospace, SFMono-Regular, monospace`
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display Hero | Inter | 64px (4.00rem) | 600 | 1.15 (tight) | -1.28px | Maximum impact, hero headlines |
| Section Heading | Inter | 40px (2.50rem) | 600 | 1.10 (tight) | -0.8px | Feature section titles |
| Sub-heading | Inter | 24px (1.50rem) | 500 | 1.30 (tight) | -0.24px | Card headings, sub-sections |
| Card Title | Inter | 20px (1.25rem) | 600 | 1.30 (tight) | -0.2px | Feature card titles |
| Card Title Light | Inter | 20px (1.25rem) | 500 | 1.30 (tight) | -0.2px | Secondary card headings |
| Body Large | Inter | 18px (1.13rem) | 400 | 1.50 | normal | Hero descriptions, introductions |
| Body | Inter | 16px (1.00rem) | 400 | 1.50 | normal | Standard reading text |
| Body Medium | Inter | 16px (1.00rem) | 500 | 1.50 | normal | Navigation, emphasized text |
| Button | Inter | 15px (0.94rem) | 500 | 1.50 | normal | Button labels |
| Link | Inter | 14px (0.88rem) | 500 | 1.50 | normal | Navigation links, small CTAs |
| Caption | Inter | 14px (0.88rem) | 400–500 | 1.50–1.71 | normal | Metadata, descriptions |
| Label Uppercase | Inter | 13px (0.81rem) | 500 | 1.50 | 0.65px | `text-transform: uppercase`, section labels |
| Small | Inter | 13px (0.81rem) | 400–500 | 1.50 | -0.26px | Small body text |
| Mono Code | Geist Mono | 12px (0.75rem) | 500 | 1.50 | 0.6px | `text-transform: uppercase`, technical labels |
| Mono Badge | Geist Mono | 12px (0.75rem) | 600 | 1.50 | 0.6px | `text-transform: uppercase`, status badges |
| Mono Micro | Geist Mono | 10px (0.63rem) | 500 | 1.50 | normal | `text-transform: uppercase`, tiny labels |
### Principles
- **Tight tracking at display sizes**: Inter at 40–64px uses -0.8px to -1.28px letter-spacing. This compression creates headlines that feel deliberate and space-efficient — documentation headings, not billboard copy.
- **Relaxed reading at body sizes**: 16–18px body text uses normal tracking with 150% line-height, creating generous reading lanes. Documentation demands comfort.
- **Two-font system**: Inter for all human-readable content, Geist Mono exclusively for technical/code contexts. The boundary is strict — no mixing.
- **Uppercase as hierarchy signal**: Section labels and technical tags use uppercase + positive tracking (0.6px–0.65px) as a clear visual delimiter between content types.
- **Three weights**: 400 (body/reading), 500 (UI/navigation/emphasis), 600 (headings/titles). No bold (700) in the system.

- Dual CTA buttons (dark primary + ghost secondary)
- The gradient creates a sense of elevation and intelligence
**Trust Bar / Logo Grid**
- "Loved by your favorite companies" section
- Company logos in muted grayscale
- Grid or horizontal layout with consistent sizing
- Subtle border separation between logos
**Feature Cards with Icons**
- Icon or illustration at top
- Title at 20px weight 600

- Consistent padding and border treatment
- Grid layout: 2–3 columns on desktop
**CTA Footer Section**
- Dark or gradient background
- Large headline: "Make documentation your winning advantage"
- Email input with pill styling
- Brand green accent on CTAs
## 5. Layout Principles
### Spacing System
- Base unit: 8px
- Scale: 2px, 4px, 5px, 6px, 7px, 8px, 10px, 12px, 16px, 24px, 32px, 48px, 64px
- Section padding: 48px–96px vertical
- Card padding: 24px–32px
- Component gaps: 8px–16px
### Grid & Container
- Max content width: approximately 1200px
- Hero: centered single-column with generous top padding (96px+)
- Feature sections: 2–3 column CSS Grid for cards
- Full-width sections with contained content
- Consistent horizontal padding: 24px (mobile) to 32px (desktop)
### Whitespace Philosophy
- **Documentation-grade breathing room**: Every element has generous surrounding whitespace. Mintlify sells documentation, so the marketing page itself demonstrates reading comfort.
- **Sections as chapters**: Each feature section is a self-contained unit with 48px–96px vertical padding, creating clear "chapter breaks."
- **Content density is low**: Unlike developer tools that pack the page, Mintlify uses 1–2 key messages per section with supporting imagery.
### Border Radius Scale
- Small (4px): Inline code, small tags, tooltips
- Medium (8px): Nav buttons, transparent buttons, small containers
- Standard (16px): Cards, content containers, image wrappers
- Large (24px): Featured cards, hero containers, section panels
- Full Pill (9999px): Buttons, inputs, badges, pills — the signature shape
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow, no border | Page background, text blocks |
| Subtle Border (Level 1) | `1px solid rgba(0,0,0,0.05)` | Standard card borders, dividers |
| Medium Border (Level 1b) | `1px solid rgba(0,0,0,0.08)` | Interactive elements, input borders |
| Ambient Shadow (Level 2) | `rgba(0,0,0,0.03) 0px 2px 4px` | Cards with subtle lift |
| Button Shadow (Level 2b) | `rgba(0,0,0,0.06) 0px 1px 2px` | Button micro-depth |
| Focus Ring (Accessibility) | `1px solid #18E299` outline | Focused inputs, active interactive elements |
**Shadow Philosophy**: Mintlify barely uses shadows. The depth system is almost entirely border-driven — ultra-subtle 5% opacity borders create separation without visual weight. When shadows appear, they're atmospheric whispers (`0.03 opacity, 2px blur, 4px spread`) that add the barest sense of lift. This restraint keeps the page feeling flat and paper-like — appropriate for a documentation company whose product is about clarity and readability.
### Decorative Depth
- Hero gradient: atmospheric green-white cloud gradient behind hero content
- No background color alternation — white on white throughout
- Depth comes from border opacity variation (5% → 8%) and whitespace
## 7. Dark Mode
### Color Inversions
- **Background**: `#0d0d0d` (near-black)
- **Text Primary**: `#ededed` (near-white)
- **Text Secondary**: `#a0a0a0` (muted gray)
- **Brand Green**: `#18E299` (unchanged — the green works on both backgrounds)
- **Border**: `rgba(255,255,255,0.08)` (white at 8% opacity)
- **Card Background**: `#141414` (slightly lighter than page)
- **Shadow**: `rgba(0,0,0,0.4) 0px 2px 4px` (stronger shadow for contrast)
### Key Adjustments
- Buttons invert: white background dark text becomes dark background light text
- Badge backgrounds shift to deeper tones with lighter text
- Focus ring remains brand green
- Hero gradient shifts to dark-tinted green atmospheric wash
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | <768px | Single column, stacked layout, hamburger nav |
| Tablet | 768–1024px | Two-column grids begin, expanded padding |
| Desktop | >1024px | Full layout, 3-column grids, maximum content width |
### Touch Targets
- Buttons with full-pill shape have comfortable 8px+ vertical padding
- Navigation links spaced with adequate 16px+ gaps
- Mobile menu provides full-width tap targets
### Collapsing Strategy
- Hero: 64px → 40px headline, maintains tight tracking proportionally
- Navigation: horizontal links + CTA → hamburger menu at 768px
- Feature cards: 3-column → 2-column → single column stacked
- Section spacing: 96px → 48px on mobile
- Footer: multi-column → stacked single column
- Trust bar: grid → horizontal scroll or stacked
### Image Behavior
- Product screenshots maintain aspect ratio with responsive containers
- Hero gradient simplifies on mobile
- Full-width sections maintain edge-to-edge treatment
## 9. Agent Prompt Guide
### Quick Color Reference
- Primary CTA: Near Black (`#0d0d0d`)
- Background: Pure White (`#ffffff`)
- Heading text: Near Black (`#0d0d0d`)
- Body text: Gray 700 (`#333333`)
- Border: `rgba(0,0,0,0.05)` (5% opacity)
- Brand accent: Green (`#18E299`)
- Link hover: Brand Green (`#18E299`)
- Focus ring: Brand Green (`#18E299`)
### Example Component Prompts
- "Create a hero section on white background with atmospheric green-white gradient wash. Headline at 64px Inter weight 600, line-height 1.15, letter-spacing -1.28px, color #0d0d0d. Subtitle at 18px Inter weight 400, line-height 1.50, color #666666. Dark pill CTA (#0d0d0d, 9999px radius, 8px 24px padding) and ghost pill button (white, 1px solid rgba(0,0,0,0.08), 9999px radius)."
- "Design a card: white background, 1px solid rgba(0,0,0,0.05) border, 16px radius, 24px padding, shadow rgba(0,0,0,0.03) 0px 2px 4px. Title at 20px Inter weight 600, letter-spacing -0.2px. Body at 14px weight 400, #666666."
- "Build a pill badge: #d4fae8 background, #0fa76e text, 9999px radius, 4px 12px padding, 13px Inter weight 500, uppercase."
- "Create navigation: white sticky header with backdrop-filter blur(12px). Inter 15px weight 500 for links, #0d0d0d text. Dark pill CTA 'Get Started' right-aligned, 9999px radius. Bottom border: 1px solid rgba(0,0,0,0.05)."
- "Design a trust section showing company logos in muted gray. Grid layout with 16px radius containers, 1px border at 5% opacity. Label above: 'Loved by your favorite companies' at 13px Inter weight 500, uppercase, tracking 0.65px."
### Iteration Guide
1. Always use full-pill radius (9999px) for buttons and inputs — this is Mintlify's signature shape
2. Keep borders at 5% opacity (`rgba(0,0,0,0.05)`) — stronger borders break the airy feeling
3. Letter-spacing scales with font size: -1.28px at 64px, -0.8px at 40px, -0.24px at 24px, normal at 16px
4. Three weights only: 400 (read), 500 (interact), 600 (announce)
5. Brand green (`#18E299`) is used sparingly — CTAs and hover states only, never for decorative fills
6. Geist Mono uppercase for technical labels, Inter for everything else
7. Section padding is generous: 64px–96px on desktop, 48px on mobile
8. No gray background sections — white throughout, separation through borders and whitespace

# Design System Inspired by Miro
> Category: Design & Creative
> Visual collaboration. Bright yellow accent, infinite canvas aesthetic.
## 1. Visual Theme & Atmosphere
Miro's website is a clean, collaborative-tool-forward platform that communicates "visual thinking" through generous whitespace, pastel accent colors, and a confident geometric font. The design uses a predominantly white canvas with near-black text (`#1c1c1e`) and a distinctive pastel color palette — coral, rose, teal, orange, yellow, moss — each representing different collaboration contexts.
The typography uses Roobert PRO Medium as the primary display font with OpenType character variants (`"blwf", "cv03", "cv04", "cv09", "cv11"`) and negative letter-spacing (-1.68px at 56px). Noto Sans handles body text with its own stylistic set (`"liga" 0, "ss01", "ss04", "ss05"`). The design is built with Framer, giving it smooth animations and modern component patterns.
**Key Characteristics:**
- White canvas with near-black (`#1c1c1e`) text
- Roobert PRO Medium with multiple OpenType character variants
- Pastel accent palette: coral, rose, teal, orange, yellow, moss (light + dark pairs)
- Blue 450 (`#5b76fe`) as primary interactive color
- Success green (`#00b473`) for positive states
- Generous border-radius: 8px–50px range

# Design System Inspired by Mistral AI
> Category: AI & LLM
> Open-weight LLM provider. French-engineered minimalism, purple-toned.
## 1. Visual Theme & Atmosphere
Mistral AI's interface is a sun-drenched landscape rendered in code — a warm, bold, unapologetically European design that trades the typical blue-screen AI aesthetic for golden amber, burnt orange, and the feeling of late-afternoon light in southern France. Every surface glows with warmth: backgrounds fade from pale cream to deep amber, shadows carry golden undertones (`rgba(127, 99, 21, ...)`), and the brand's signature orange (`#fa520f`) burns through the page like a signal fire.
The design language is maximalist in its warmth but minimalist in its structure. Huge display headlines (82px) crash into the viewport with aggressive negative tracking (-2.05px), creating text blocks that feel like billboards or protest posters — declarations rather than descriptions. The typography uses Arial (likely a custom font with Arial as fallback) at extreme sizes, creating a raw, unadorned voice that says "we build frontier AI" with no decoration needed.
What makes Mistral distinctive is the complete commitment to a warm color temperature. The signature "block" identity — a gradient system flowing from bright yellow (`#ffd900`) through amber (`#ffa110`) to burnt orange (`#fa520f`) — creates a visual identity that's immediately recognizable. Even the shadows are warm, using amber-tinted blacks instead of cool grays. Combined with dramatic landscape photography in golden tones, the design feels less like a tech company and more like a European luxury brand that happens to build language models.
**Key Characteristics:**
- Golden-amber color universe: every tone from pale cream (#fffaeb) to burnt orange (#fa520f)
- Massive display typography (82px) with aggressive negative letter-spacing (-2.05px)
- Warm golden shadow system using amber-tinted rgba values
- The Mistral "M" block identity — a gradient from yellow to orange
- Dramatic landscape photography in warm golden tones
- Uppercase typography used strategically for section labels and CTAs
- Near-zero border-radius — sharp, architectural geometry
- French-European confidence: bold, warm, declarative
## 2. Color Palette & Roles
### Primary
- **Mistral Orange** (`#fa520f`): The core brand color — a vivid, saturated orange-red that anchors the entire identity. Used for primary emphasis, the brand block, and the highest-signal moments.
- **Mistral Flame** (`#fb6424`): A slightly warmer, lighter variant of the brand orange used for secondary brand moments and hover states.
- **Block Orange** (`#ff8105`): A pure orange used in the gradient block system — warmer and less red than Mistral Orange.
### Secondary & Accent
- **Sunshine 900** (`#ff8a00`): Deep golden amber — the darkest sunshine tone, used for strong accent moments.
- **Sunshine 700** (`#ffa110`): Warm amber-gold — the core sunshine accent for backgrounds and interactive elements.
- **Sunshine 500** (`#ffb83e`): Medium golden — balanced warmth for mid-level emphasis.
- **Sunshine 300** (`#ffd06a`): Light golden — for subtle warm tints and secondary backgrounds.
- **Block Gold** (`#ffe295`): Pale gold — soft background accents and gentle warmth.
- **Bright Yellow** (`#ffd900`): The brightest tone in the gradient — used at the "top" of the block identity.
### Surface & Background
- **Warm Ivory** (`#fffaeb`): The lightest page background — barely tinted with warmth, the foundation canvas.
- **Cream** (`#fff0c2`): The primary warm surface and secondary button background — noticeably golden.
- **Pure White** (`#ffffff`): Used for maximum contrast elements and popover surfaces.
- **Mistral Black** (`#1f1f1f`): The primary dark surface for buttons, text, and dark sections.
- **Accent Orange** (defined as `hsl(17, 96%, 52%)`): The functional accent color for interactive states.
### Neutrals & Text
- **Mistral Black** (`#1f1f1f`): Primary text color and dark button backgrounds — a near-black that's warmer than pure #000.
- **Black Tint** (defined as `hsl(0, 0%, 24%)`): A medium dark gray for secondary text on light backgrounds.
- **Pure White** (`#ffffff`): Text on dark surfaces and CTA labels.
### Semantic & Accent
- **Input Border** (defined as `hsl(240, 5.9%, 90%)`): A cool-tinted light gray for form borders — one of the few cool tones in the system.
- **White Overlay** (`oklab(1, 0, 0 / 0.088–0.1)`): Semi-transparent white for frosted glass effects and button overlays.
### Gradient System
- **Mistral Block Gradient**: The signature identity — a multi-step gradient flowing through Yellow (`#ffd900`) → Gold (`#ffe295`) → Amber (`#ffa110`) → Orange (`#ff8105`) → Flame (`#fb6424`) → Mistral Orange (`#fa520f`). This gradient appears in the logo blocks, section backgrounds, and decorative elements.
- **Golden Landscape Wash**: Photography and backgrounds use warm amber overlays creating a consistent golden temperature across the page.
- **Warm Shadow Cascade**: Multi-layered golden shadows that build depth with amber-tinted transparency rather than gray.
## 3. Typography Rules
### Font Family
- **Primary**: Likely a custom font (Font Source detected) with `Arial` as fallback, and extended stack: `ui-sans-serif, system-ui, Apple Color Emoji, Segoe UI Emoji, Segoe UI Symbol, Noto Color Emoji`
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display / Hero | Arial (custom) | 82px (5.13rem) | 400 | 1.00 (tight) | -2.05px | Maximum impact, billboard scale |
| Section Heading | Arial (custom) | 56px (3.5rem) | 400 | 0.95 (ultra-tight) | normal | Feature section anchors |
| Sub-heading Large | Arial (custom) | 48px (3rem) | 400 | 0.95 (ultra-tight) | normal | Secondary section titles |
| Sub-heading | Arial (custom) | 32px (2rem) | 400 | 1.15 (tight) | normal | Card headings, feature names |
| Card Title | Arial (custom) | 30px (1.88rem) | 400 | 1.20 (tight) | normal | Mid-level headings |
| Feature Title | Arial (custom) | 24px (1.5rem) | 400 | 1.33 | normal | Small headings |
| Body / Button | Arial (custom) | 16px (1rem) | 400 | 1.50 | normal | Standard body, button text |
| Button Uppercase | Arial (custom) | 16px (1rem) | 400 | 1.50 | normal | Uppercase CTA labels |
| Caption / Link | Arial (custom) | 14px (0.88rem) | 400 | 1.43 | normal | Metadata, secondary links |
### Principles
- **Single weight, maximum impact**: The entire system uses weight 400 (regular) — even at 82px. This creates a surprisingly elegant effect where the size alone carries authority without needing bold weight.
- **Ultra-tight at scale**: Line-heights of 0.95–1.00 at display sizes create text blocks where ascenders nearly touch descenders from the line above — creating dense, poster-like composition.
- **Aggressive tracking on display**: -2.05px letter-spacing at 82px compresses the hero text into a monolithic block.
- **Uppercase as emphasis**: Strategic `text-transform: uppercase` on button labels and section markers creates a formal, European signage quality.
- **No weight variation**: Unlike most systems that use 300–700 weight range, Mistral uses 400 everywhere. Hierarchy comes from size and color, never weight.
## 4. Component Stylings
### Buttons
**Cream Surface**
- Background: Cream (`#fff0c2`)
- Text: Mistral Black (`#1f1f1f`)
- No visible border
- The warm, inviting secondary CTA
**Dark Solid**
- Background: Mistral Black (`#1f1f1f`)
- Text: Pure White (`#ffffff`)
- Padding: 12px (all sides)
- No visible border
- The primary action button — dark on warm
**Ghost / Transparent**
- Background: transparent with slight dark overlay (`oklab(0, 0, 0 / 0.1)`)
- Text: Mistral Black (`#1f1f1f`)
- Opacity: 0.4
- For secondary/de-emphasized actions
**Text / Underline**
- Background: transparent
- Text: Mistral Black (`#1f1f1f`)
- Padding: 8px 0px 0px (top-only)
- Minimal styling — text link as button
- For tertiary navigation actions
### Cards & Containers
- Background: Warm Ivory (`#fffaeb`), Cream (`#fff0c2`), or Pure White
- Border: minimal to none — containers defined by background color
- Radius: near-zero — sharp, architectural corners
- Shadow: warm golden multi-layer (`rgba(127, 99, 21, 0.12) -8px 16px 39px, rgba(127, 99, 21, 0.1) -33px 64px 72px, rgba(127, 99, 21, 0.06) -73px 144px 97px, ...`) — a dramatic, cascading warm shadow
- Distinctive: the golden shadow creates a "golden hour" lighting effect
### Inputs & Forms
- Border: `hsl(240, 5.9%, 90%)` — the sole cool-toned element
- Focus: accent color ring
- Minimal styling consistent with sparse aesthetic
### Navigation
- Transparent nav overlaying the warm hero
- Logo: Mistral "M" wordmark
- Links: Dark text (white on dark sections)
- CTA: Dark solid button or cream surface button
- Minimal, wide-spaced layout
### Image Treatment
- Dramatic landscape photography in warm golden tones
- The winding road through golden hills — a recurring visual motif
- The Mistral "M" rendered at large scale on golden backgrounds
- Warm color grading on all photography
- Full-bleed sections with photography
### Distinctive Components
**Mistral Block Identity**
- A row of colored blocks forming the gradient: yellow → amber → orange → burnt orange
- Each block gets progressively more orange/red
- The visual DNA of the brand — recognizable at any size
**Golden Shadow Cards**
- Cards elevated with warm amber multi-layered shadows
- 5 layers of shadow from 16px to 400px offset
- Creates a "floating in golden light" effect unique to Mistral
**Dark Footer Gradient**
- Footer transitions from warm amber to dark through a dramatic gradient
- Creates a "sunset" effect as the page ends
## 5. Layout Principles
### Spacing System
- Base unit: 8px
- Scale: 2px, 4px, 8px, 10px, 12px, 16px, 20px, 24px, 32px, 40px, 48px, 64px, 80px, 98px, 100px
- Button padding: 12px or 8px 0px (compact)
- Section vertical spacing: very generous (80px–100px)
### Grid & Container
- Max container width: approximately 1280px, centered
- Hero: full-width with massive typography overlaying warm backgrounds
- Feature sections: wide-format layouts with dramatic imagery
- Card grids: 2–3 column layouts
### Whitespace Philosophy
- **Bold declarations**: Huge headlines surrounded by generous whitespace create billboard-like impact — each statement gets its own breathing space.
- **Warm void**: Empty space itself feels warm because the backgrounds are tinted ivory/cream rather than pure white.
- **Photography as space-filler**: Large landscape images serve double duty as content and decorative whitespace.
### Border Radius Scale
- Near-zero: The dominant radius — sharp, architectural corners on most elements
- This extreme sharpness contrasts with the warmth of the colors, creating a tension between soft color and hard geometry.
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Page backgrounds, text blocks |
| Golden Float (Level 1) | Multi-layer warm shadow (5 layers, 12%→0% opacity, amber-tinted) | Feature cards, product showcases, elevated content |
**Shadow Philosophy**: Mistral uses a single but extraordinarily complex shadow — **five cascading layers** of amber-tinted shadow (`rgba(127, 99, 21, ...)`) that build from a close 16px offset to a distant 400px offset. The result is a rich, warm, "golden hour" lighting effect that makes elevated elements look like they're bathed in afternoon sunlight. This is the most distinctive shadow system in any major AI brand.
## 7. Do's and Don'ts
### Do
- Use the warm color spectrum exclusively: ivory, cream, amber, gold, orange
- Keep display typography at 82px+ with -2.05px letter-spacing for hero sections
- Use the Mistral block gradient (yellow → amber → orange) for brand moments
- Apply warm golden shadows (amber-tinted rgba) for elevated elements
- Use Mistral Black (#1f1f1f) for text — never pure #000000
- Keep font weight at 400 throughout — let size and color carry hierarchy
- Use sharp, architectural corners — near-zero border-radius
- Apply uppercase on button labels and section markers for European formality
- Use warm landscape photography with golden color grading
### Don't
- Don't introduce cool colors (blue, green, purple) — the palette is exclusively warm
- Don't use bold (700+) weight — 400 is the only weight
- Don't round corners — the sharp geometry is intentional
- Don't use cool-toned shadows — shadows must carry amber warmth
- Don't use pure white as a page background — always warm-tinted (#fffaeb minimum)
- Don't reduce hero text below 48px on desktop — the billboard scale is core
- Don't use more than 2 font weights — size variation replaces weight variation
- Don't add gradients outside the warm spectrum — no blue-to-purple, no cool transitions
- Don't use generic gray for text — even neutrals should be warm-tinted
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | <640px | Single column, stacked everything, hero text reduces to ~32px |
| Tablet | 640–768px | Minor layout adjustments |
| Small Desktop | 768–1024px | 2-column layouts begin |
| Desktop | 1024–1280px | Full layout with maximum typography scale |
### Touch Targets
- Buttons use generous padding (12px minimum)
- Navigation elements adequately spaced
- Cards serve as large touch targets
### Collapsing Strategy
- **Navigation**: Collapses to hamburger on mobile
- **Hero text**: 82px → 56px → 48px → 32px progressive scaling
- **Feature sections**: Multi-column → stacked
- **Photography**: Scales proportionally, may crop on mobile
- **Block identity**: Scales down proportionally
### Image Behavior
- Landscape photography scales proportionally
- Warm color grading maintained at all sizes
- Block gradient elements resize fluidly
- No art direction changes — same warm composition at all sizes
## 9. Agent Prompt Guide
### Quick Color Reference
- Brand Orange: "Mistral Orange (#fa520f)"
- Page Background: "Warm Ivory (#fffaeb)"
- Warm Surface: "Cream (#fff0c2)"
- Primary Text: "Mistral Black (#1f1f1f)"
- Sunshine Amber: "Sunshine 700 (#ffa110)"
- Bright Gold: "Bright Yellow (#ffd900)"
- Text on Dark: "Pure White (#ffffff)"
### Example Component Prompts
- "Create a hero section on Warm Ivory (#fffaeb) with a massive headline at 82px Arial weight 400, line-height 1.0, letter-spacing -2.05px. Mistral Black (#1f1f1f) text. Add a dark solid CTA button (#1f1f1f bg, white text, 12px padding, sharp corners) and a cream secondary button (#fff0c2 bg)."
- "Design a feature card on Cream (#fff0c2) with sharp corners (no border-radius). Apply the golden shadow system: rgba(127, 99, 21, 0.12) -8px 16px 39px as the primary layer. Title at 32px weight 400, body at 16px."
- "Build the Mistral block identity: a row of colored blocks from Bright Yellow (#ffd900) through Sunshine 700 (#ffa110) to Mistral Orange (#fa520f). Sharp corners, no gaps."
- "Create a dark footer section on Mistral Black (#1f1f1f) with Pure White (#ffffff) text. Footer links at 14px. Add a warm gradient from Sunshine 700 (#ffa110) at the top fading to Mistral Black."
### Iteration Guide
1. Keep the warm temperature — "shift toward amber" not "shift toward gray"
2. Use size for hierarchy — 82px → 56px → 48px → 32px → 24px → 16px
3. Never add border-radius — sharp corners only
4. Shadows are always warm: "golden shadow with amber tones"
5. Font weight is always 400 — describe emphasis through size and color

# Design System Inspired by MongoDB
> Category: Backend & Data
> Document database. Green leaf branding, developer documentation focus.
## 1. Visual Theme & Atmosphere
MongoDB's website is a deep-forest-meets-terminal experience — a design system rooted in the darkest teal-black (`#001e2b`) that evokes both the density of a database and the depth of a forest canopy. Against this near-black canvas, a striking neon green (`#00ed64`) pulses as the brand accent — bright enough to feel electric, organic enough to feel alive. This isn't the cold neon of cyberpunk; it's the bioluminescent green of something growing in the dark.
The typography system is architecturally ambitious: MongoDB Value Serif for massive hero headlines (96px) creates an editorial, authoritative presence — serif type at database-company scale is a bold choice that says "we're not just another tech company." Euclid Circular A handles the heavy lifting of body and UI text with an unusually wide weight range (300–700), while Source Code Pro serves as the code and label font with distinctive uppercase treatments featuring very wide letter-spacing (1px–3px). This three-font system creates a hierarchy that spans editorial elegance → geometric professionalism → engineering precision.
What makes MongoDB distinctive is its dual-mode design: a dark hero/feature section world (`#001e2b` with neon green accents) and a light content world (white with teal-gray borders `#b8c4c2`). The transition between these modes creates dramatic contrast. The shadow system uses teal-tinted dark shadows (`rgba(0, 30, 43, 0.12)`) that maintain the forest-dark atmosphere even on light surfaces. Buttons use pill shapes (100px–999px radius) with MongoDB Green borders (`#00684a`), and the entire component system references the LeafyGreen design system.
**Key Characteristics:**
- Deep teal-black backgrounds (`#001e2b`) — forest-dark, not space-dark
- Neon MongoDB Green (`#00ed64`) as the singular brand accent — electric and organic
- MongoDB Value Serif for hero headlines — editorial authority at tech scale
- Euclid Circular A for body with weight 300 (light) as a distinctive body weight
- Source Code Pro with wide uppercase letter-spacing (1px–3px) for technical labels
- Teal-tinted shadows: `rgba(0, 30, 43, 0.12)` — shadows carry the forest color
- Dual-mode: dark teal hero sections + light white content sections
- Pill buttons (100px radius) with green borders (`#00684a`)
- Link Blue (`#006cfa`) and hover transition to `#3860be`
## 2. Color Palette & Roles
### Primary Brand
- **Forest Black** (`#001e2b`): Primary dark background — the deepest teal-black
- **MongoDB Green** (`#00ed64`): Primary brand accent — neon green for highlights, underlines, gradients
- **Dark Green** (`#00684a`): Button borders, link text on light — muted green for functional use
### Interactive
- **Action Blue** (`#006cfa`): Secondary accent — links, interactive highlights
- **Hover Blue** (`#3860be`): All link hover states transition to this blue
- **Teal Active** (`#1eaedb`): Button hover background — bright teal
### Neutral Scale
- **Deep Teal** (`#1c2d38`): Dark button backgrounds, secondary dark surfaces
- **Teal Gray** (`#3d4f58`): Dark borders on dark surfaces
- **Dark Slate** (`#21313c`): Dark link text variant
- **Cool Gray** (`#5c6c75`): Muted text on dark, secondary button text
- **Silver Teal** (`#b8c4c2`): Borders on light surfaces, dividers
- **Light Input** (`#e8edeb`): Input text on dark surfaces
- **Pure White** (`#ffffff`): Light section background, button text on dark
- **Black** (`#000000`): Text on light surfaces, darkest elements
### Shadows
- **Forest Shadow** (`rgba(0, 30, 43, 0.12) 0px 26px 44px, rgba(0, 0, 0, 0.13) 0px 7px 13px`): Primary card elevation — teal-tinted
- **Standard Shadow** (`rgba(0, 0, 0, 0.15) 0px 3px 20px`): General elevation
- **Subtle Shadow** (`rgba(0, 0, 0, 0.1) 0px 2px 4px`): Light card lift
## 3. Typography Rules
### Font Families
- **Display Serif**: `MongoDB Value Serif` — editorial hero headlines
- **Body / UI**: `Euclid Circular A` — geometric sans-serif workhorse
- **Code / Labels**: `Source Code Pro` — monospace with uppercase label treatments
- **Fallbacks**: `Akzidenz-Grotesk Std` (with CJK: Noto Sans KR/SC/JP), `Times`, `Arial`, `system-ui`
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display Hero | MongoDB Value Serif | 96px (6.00rem) | 400 | 1.20 (tight) | normal | Serif authority |
| Display Secondary | MongoDB Value Serif | 64px (4.00rem) | 400 | 1.00 (tight) | normal | Serif sub-hero |
| Section Heading | Euclid Circular A | 36px (2.25rem) | 500 | 1.33 | normal | Geometric precision |
| Sub-heading | Euclid Circular A | 24px (1.50rem) | 500 | 1.33 | normal | Feature titles |
| Body Large | Euclid Circular A | 20px (1.25rem) | 400 | 1.60 (relaxed) | normal | Introductions |
| Body | Euclid Circular A | 18px (1.13rem) | 400 | 1.33 | normal | Standard body |
| Body Light | Euclid Circular A | 16px (1.00rem) | 300 | 1.50–2.00 | normal | Light-weight reading text |
| Nav / UI | Euclid Circular A | 16px (1.00rem) | 500 | 1.00–1.88 | 0.16px | Navigation, emphasized |
| Body Bold | Euclid Circular A | 15px (0.94rem) | 700 | 1.50 | normal | Strong emphasis |
| Button | Euclid Circular A | 13.5px–16px | 500–700 | 1.00 | 0.135px–0.9px | CTA labels |
| Caption | Euclid Circular A | 14px (0.88rem) | 400 | 1.71 (relaxed) | normal | Metadata |
| Small | Euclid Circular A | 11px (0.69rem) | 600 | 1.82 (relaxed) | 0.2px | Tags, annotations |
| Code Heading | Source Code Pro | 40px (2.50rem) | 400 | 1.60 (relaxed) | normal | Code showcase titles |
| Code Body | Source Code Pro | 16px (1.00rem) | 400 | 1.50 | normal | Code blocks |
| Code Label | Source Code Pro | 14px (0.88rem) | 400–500 | 1.14 (tight) | 1px–2px | `text-transform: uppercase` |
| Code Micro | Source Code Pro | 9px (0.56rem) | 600 | 2.67 (relaxed) | 2.5px | `text-transform: uppercase` |
### Principles
- **Serif for authority**: MongoDB Value Serif at hero scale creates an editorial presence unusual in tech — it communicates that MongoDB is an institution, not a startup.
- **Weight 300 as body default**: Euclid Circular A uses light (300) for body text, creating an airy reading experience that contrasts with the dense, dark backgrounds.
- **Wide-tracked monospace labels**: Source Code Pro uppercase at 1px–3px letter-spacing creates technical signposts that feel like database field labels — systematic, structured, classified.
- **Four-weight range**: 300 (light body) → 400 (standard) → 500 (UI/nav) → 700 (bold CTA) — a wider range than most systems, enabling fine-grained hierarchy.
## 4. Component Stylings
### Buttons
**Primary Green (Dark Surface)**
- Background: `#00684a` (muted MongoDB green)
- Text: `#000000`

- Dark mode: `#001e2b` or `#1c2d38` background with `1px solid #3d4f58`
- Radius: 16px (standard), 24px (medium), 48px (large/hero)
- Shadow: `rgba(0,30,43,0.12) 0px 26px 44px` (forest-tinted)
- Image containers: 30px–32px radius
### Inputs & Forms
- Textarea: text `#e8edeb`, padding 12px 12px 12px 8px
- Borders: `1px solid #b8c4c2` on light, `1px solid #3d4f58` on dark
- Input radius: 4px
### Navigation
- Dark header on forest-black background
- Euclid Circular A 16px weight 500 for nav links
- MongoDB logo (leaf icon + wordmark) left-aligned
- Green CTA pill buttons right-aligned
- Mega-menu dropdowns with product categories
### Image Treatment
- Dashboard screenshots on dark backgrounds
- Green-accented UI elements in screenshots
- 30px–32px radius on image containers
- Full-width dark sections for product showcases
### Distinctive Components
**Neon Green Accent Underlines**
- `0px 2px 2px 0px solid #00ed64` — bottom + right border creating accent underlines
- Used on feature headings and highlighted text
- Also appears as `#006cfa` (blue) variant
**Source Code Label System**
- 14px uppercase Source Code Pro with 1px–2px letter-spacing
- Used as section category markers above headings
- Creates a "database field label" aesthetic
## 5. Layout Principles
### Spacing System
- Base unit: 8px
- Scale: 1px, 4px, 7px, 8px, 10px, 12px, 14px, 15px, 16px, 18px, 20px, 24px, 32px
### Grid & Container
- Max content width centered
- Dark hero section with contained content
- Light content sections below
- Card grids: 2–3 columns
- Full-width dark footer
### Whitespace Philosophy
- **Dramatic mode transitions**: The shift from dark teal sections to white content creates built-in visual breathing through contrast, not just space.
- **Generous dark sections**: Dark hero and feature areas use extra vertical padding (80px+) to let the forest-dark background breathe.
- **Compact light sections**: White content areas are denser, with tighter card grids and less vertical spacing.
### Border Radius Scale
- Minimal (1px–2px): Small spans, badges
- Subtle (4px): Inputs, small buttons
- Standard (8px): Cards, links
- Card (16px): Standard cards, containers
- Toggle (20px): Switch elements
- Large (24px): Large panels
- Image (30px–32px): Image containers
- Hero (48px): Hero cards
- Pill (100px–999px): Buttons, navigation pills
- Full (9999px): Maximum pill
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Default surfaces |
| Subtle (Level 1) | `rgba(0,0,0,0.1) 0px 2px 4px` | Light card lift |
| Standard (Level 2) | `rgba(0,0,0,0.15) 0px 3px 9px` | Standard cards |
| Prominent (Level 3) | `rgba(0,0,0,0.15) 0px 3px 20px` | Elevated panels |
| Forest (Level 4) | `rgba(0,30,43,0.12) 0px 26px 44px, rgba(0,0,0,0.13) 0px 7px 13px` | Hero cards — teal-tinted |
**Shadow Philosophy**: MongoDB's shadow system is unique in that the primary elevation shadow uses `rgba(0, 30, 43, 0.12)` — a teal-tinted shadow that carries the forest-dark brand color into the depth system. This means even on white surfaces, shadows feel like they belong to the MongoDB color world rather than being generic neutral black.
## 7. Do's and Don'ts
### Do
- Use `#001e2b` (forest-black) for dark sections — not pure black
- Apply MongoDB Green (`#00ed64`) sparingly for maximum electric impact
- Use MongoDB Value Serif ONLY for hero/display headings — Euclid Circular A for everything else
- Apply Source Code Pro uppercase with wide tracking (1px–3px) for technical labels
- Use teal-tinted shadows (`rgba(0,30,43,0.12)`) for primary card elevation
- Maintain the dark/light section duality — dramatic contrast between modes
- Use weight 300 for body text — the light weight is the readable voice
- Apply pill radius (100px) to primary action buttons
### Don't
- Don't use pure black (`#000000`) for dark backgrounds — always use teal-black (`#001e2b`)
- Don't use MongoDB Green (`#00ed64`) on backgrounds — it's an accent for text, underlines, and small highlights
- Don't use standard gray shadows — always use teal-tinted (`rgba(0,30,43,...)`)
- Don't apply serif font to body text — MongoDB Value Serif is hero-only
- Don't use narrow letter-spacing on Source Code Pro labels — the wide tracking IS the identity
- Don't mix dark and light section treatments within the same section
- Don't use warm colors — the palette is strictly cool (teal, green, blue)
- Don't forget the green accent underlines — they're the signature decorative element
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile Small | <425px | Tight single column |
| Mobile | 425–768px | Standard mobile |
| Tablet | 768–1024px | 2-column grids begin |
| Desktop | 1024–1280px | Standard layout |
| Large Desktop | 1280–1440px | Expanded layout |
| Ultra-wide | >1440px | Maximum width, generous margins |
### Touch Targets
- Pill buttons with generous padding
- Navigation links at 16px with adequate spacing
- Card surfaces as full-area touch targets
### Collapsing Strategy
- Hero: MongoDB Value Serif 96px → 64px → scales further
- Navigation: horizontal mega-menu → hamburger
- Feature cards: multi-column → stacked
- Dark/light sections maintain their mode at all sizes
- Source Code Pro labels maintain uppercase treatment
### Image Behavior
- Dashboard screenshots scale proportionally
- Dark section backgrounds maintained full-width
- Image radius maintained across breakpoints
## 9. Agent Prompt Guide
### Quick Color Reference
- Dark background: Forest Black (`#001e2b`)
- Brand accent: MongoDB Green (`#00ed64`)
- Functional green: Dark Green (`#00684a`)
- Link blue: Action Blue (`#006cfa`)
- Text on light: Black (`#000000`)
- Text on dark: White (`#ffffff`) or Light Input (`#e8edeb`)
- Border light: Silver Teal (`#b8c4c2`)
- Border dark: Teal Gray (`#3d4f58`)
### Example Component Prompts
- "Create a hero on forest-black (#001e2b) background. Headline at 96px MongoDB Value Serif weight 400, line-height 1.20, white text with 'potential' highlighted in MongoDB Green (#00ed64). Subtitle at 18px Euclid Circular A weight 400. Green pill CTA (#00684a, 100px radius). Neon green gradient glow behind product screenshot."
- "Design a card on white background: 1px solid #b8c4c2 border, 16px radius, shadow rgba(0,30,43,0.12) 0px 26px 44px. Title at 24px Euclid Circular A weight 500. Body at 16px weight 300. Source Code Pro 14px uppercase label above title with 2px letter-spacing."
- "Build a dark section: #001e2b background, 1px solid #3d4f58 border on cards. White text. MongoDB Green (#00ed64) accent underlines on headings using bottom-border 2px solid."
- "Create technical label: Source Code Pro 14px, text-transform uppercase, letter-spacing 2px, weight 500, #00ed64 color on dark background."
- "Design a pill button: #1c2d38 background, 1px solid #3d4f58 border, 100px radius, #5c6c75 text. Hover: #1eaedb background, white text, translateX(5px)."
### Iteration Guide
1. Start with the mode decision: dark (#001e2b) for hero/features, white for content
2. MongoDB Green (#00ed64) is electric — use once per section for maximum impact
3. Serif headlines (MongoDB Value Serif) create the editorial authority — never use for body
4. Weight 300 body text creates the airy reading experience — don't default to 400
5. Source Code Pro uppercase with wide tracking for technical labels — the database voice
6. Teal-tinted shadows keep everything in the MongoDB color world

# Design System Inspired by Nike
> Category: E-Commerce & Retail
> Athletic retail. Monochrome UI, massive uppercase type, full-bleed photography.
## 1. Visual Theme & Atmosphere
Nike.com is a kinetic retail cathedral — a site that channels the explosive energy of sport into a digital shopping experience. The design operates on a principle of radical simplicity: strip everything back to black, white, and grey so that athletic photography and product color can dominate without competition. The result feels less like a website and more like a sports editorial laid out with the precision of a luxury magazine. Every pixel of real estate is either selling product or driving toward product.
The "Podium CDS" (Nike's internal Core Design System) establishes an aggressively monochromatic foundation. The UI disappears into black (`#111111`) text and white surfaces, allowing hero photography — sweating athletes, mid-air shoes, stadium energy — to carry the emotional weight. When color does appear in the UI, it's almost exclusively functional: red for errors, blue for links, green for success. The product itself is the color story. This restraint creates a visual paradox: the most colorful pages on the internet feel the most minimal, because all vibrancy comes from merchandise rather than interface.
The typography system is the other half of Nike's visual identity. Massive uppercase headlines in Nike Futura ND — a custom condensed Futura variant with impossibly tight line-height (0.90) — punch through hero imagery like a typographic shockwave. Below the headlines, the workhorse Helvetica Now family handles everything from navigation to product descriptions with Swiss-precision clarity. This split between expressive display type and functional body type mirrors Nike's brand duality: inspiration meets execution.
**Key Characteristics:**
- Monochromatic UI (black/white/grey) that lets product photography be the only color source
- Massive uppercase display typography (96px, line-height 0.90) that punches through hero images
- Full-bleed photography with no border radius — imagery fills every available edge
- Pill-shaped buttons (30px radius) as the primary interactive element
- 8px spacing grid with athletic discipline — every measurement snaps to the system
- Category-driven shopping architecture with large navigational image cards
- Shadow-free, border-minimal elevation model — surface differentiation through grey shifts only
## 2. Color Palette & Roles
### Primary
- **Nike Black** (`#111111`): The foundation — primary text, button backgrounds, nav text, hero overlays. Deliberately not pure black (#000000), creating a fractionally softer reading experience
- **Nike White** (`#FFFFFF`): Primary page canvas, button text on dark, card surfaces, nav bar background
### Surface & Background
- **Snow** (`#FAFAFA`): Lightest surface, near-white subtle differentiation (--podium-cds-color-grey-50)
- **Light Gray** (`#F5F5F5`): Secondary background, search input fill, image placeholder, loading skeleton (--podium-cds-color-grey-100)
- **Hover Gray** (`#E5E5E5`): Hover state background, disabled button fill (--podium-cds-color-grey-200)
- **Dark Surface** (`#28282A`): Primary background on dark/inverted sections (--podium-cds-color-grey-800)
- **Deep Charcoal** (`#1F1F21`): Inverse primary background, darkest non-black surface (--podium-cds-color-grey-900)
- **Dark Hover** (`#39393B`): Hover state on dark backgrounds (--podium-cds-color-grey-700)
### Neutrals & Text
- **Primary Text** (`#111111`): Main body text, headings, nav links (--podium-cds-color-text-primary)
- **Secondary Text** (`#707072`): Descriptive copy, metadata, timestamps, price labels (--podium-cds-color-text-secondary)
- **Disabled Text** (`#9E9EA0`): Inactive elements, unavailable options (--podium-cds-color-text-disabled)
- **Disabled Inverse** (`#4B4B4D`): Disabled text on dark backgrounds (--podium-cds-color-text-disabled-inverse)
- **Border Primary** (`#707072`): Standard border color, matching secondary text
- **Border Secondary** (`#CACACB`): Subtle borders, input borders, divider lines (--podium-cds-color-grey-300)
- **Border Disabled** (`#CACACB`): Inactive border state
- **Border Active** (`#111111`): Active/focused border, matching primary text
### Semantic & Accent
- **Nike Red** (`#D30005`): Critical errors, sale badges, urgent notifications (--podium-cds-color-red-600)
- **Bright Red** (`#EE0005`): Red-500, slightly lighter red for emphasis
- **Nike Orange Badge** (`#D33918`): Badge text, promotional callouts (--podium-cds-color-text-badge)
- **Orange Flash** (`#FF5000`): Expressive orange accent (--podium-cds-color-orange-400)
- **Success Green** (`#007D48`): Confirmation, availability, positive states (--podium-cds-color-green-600)
- **Success Inverse** (`#1EAA52`): Success on dark backgrounds (--podium-cds-color-green-500)
- **Link Blue** (`#1151FF`): Text links, informational highlights (--podium-cds-color-blue-500)
- **Info Inverse** (`#1190FF`): Links on dark backgrounds (--podium-cds-color-blue-400)
- **Warning Yellow** (`#FEDF35`): Warning backgrounds, attention banners (--podium-cds-color-yellow-200)
- **Focus Ring** (`rgba(39, 93, 197, 1)`): Keyboard focus indicator ring
### Extended Color Spectrum (Podium CDS)
Each color ramp runs 50–900 for expressive use in campaigns and product pages:
- **Red**: `#FFE5E5` → `#EE0005` → `#530300`
- **Orange**: `#FFE2D6` → `#FF5000` → `#3E1009`
- **Yellow**: `#FEF087` → `#FCA600` → `#99470A`
- **Green**: `#DFFFB9` → `#1EAA52` → `#003C2A`
- **Teal**: `#D4FFFB` → `#008E98` → `#043441`
- **Blue**: `#D6EEFF` → `#1151FF` → `#020664`
- **Purple**: `#E4E1FC` → `#6E0FF6` → `#1C0060`
- **Pink**: `#FFE1F3` → `#ED1AA0` → `#4C012D`
### Gradient System
Nike avoids UI gradients. When gradients appear, they are photographic — applied to product hero backgrounds (e.g., a red shoe on a red-to-deeper-red gradient). The design system itself is flat-color only.
## 3. Typography Rules
### Font Family
**Display:** Nike Futura ND (custom condensed Futura variant exclusive to Nike)
- Fallbacks: Helvetica Now Text Medium, Helvetica, Arial

**Body:** Helvetica Now Text (weight 400)
- Fallbacks: Helvetica, Arial
- Used for standard body copy, descriptions, metadata
**Arabic:** Neue Frutiger Arabic — locale-specific alternative
### Hierarchy
| Role | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|--------|-------------|----------------|-------|
| Display | 96px | 500 | 0.90 | — | Nike Futura ND, uppercase, hero headlines |
| Heading 1 | 32px | 500 | 1.20 | — | Helvetica Now Display Medium, section titles |
| Heading 2 | 24px | 500 | 1.20 | — | Helvetica Now Display Medium, subsections |
| Heading 3 | 16px | 500 | 1.50 | — | Helvetica Now Text Medium, card titles |
| Body | 16px | 400 | 1.75 | — | Helvetica Now Text, product descriptions |
| Body Medium | 16px | 500 | 1.75 | — | Helvetica Now Text Medium, emphasized text |
| Link | 16px | 500 | 1.75 | — | Helvetica Now Text Medium, navigation links |
| Link Small | 14px | 500 | 1.86 | — | Helvetica Now Text Medium, footer/utility links |
| Button | 16px | 500 | 1.50 | — | Helvetica Now Text Medium, CTA text |
| Button Small | 14px | 500 | 1.50 | — | Helvetica Now Text Medium, secondary buttons |
| Caption | 14px | 500 | 1.50 | — | Helvetica Now Text Medium, price labels |
| Small | 12px | 500 | 1.50 | — | Helvetica Now Text Medium, timestamps |
| Tiny | 12px | 400 | 1.50 | — | Helvetica Now Text, legal text |
### Principles
Nike's typography is a study in tension. The display layer — Nike Futura ND at 96px with a devastating 0.90 line-height — is engineered to feel like a stadium scoreboard: massive, condensed, uppercase, impossible to ignore. It transforms headlines into battle cries. Below the display layer, Helvetica Now provides a clinical counterpoint: Swiss-precision legibility with generous 1.75 line-height for comfortable product browsing. Weight 500 (Medium) dominates throughout the body text, giving Nike's prose a slight assertiveness without the heaviness of bold — every sentence reads like a confident recommendation, not a shout.

## 5. Layout Principles
### Spacing System
Base unit: 4px (primary grid is 8px multiples)
| Token | Value | Use |
|-------|-------|-----|
| space-1 | 4px | Tight icon gaps, inline spacing |
| space-2 | 8px | Base unit, button icon gaps |
| space-3 | 12px | Card internal padding, tight margins |
| space-4 | 16px | Standard padding, nav spacing |
| space-5 | 20px | Product card gaps |
| space-6 | 24px | Section internal padding, grid gaps |
| space-7 | 32px | Section breaks |
| space-8 | 48px | Major section padding |
| space-9 | 64px | Hero section padding |
| space-10 | 80px | Large section spacing |
### Grid & Container
- Max container width: 1920px
- Standard content width: ~1440px with horizontal padding
- Product grid: 3-column on desktop, 2-column on tablet, 1-column on mobile
- Category grid: 3-column with full-bleed images
- Grid gap: 4-12px between product cards (intentionally tight)
- Horizontal padding: 48px desktop, 24px tablet, 16px mobile
### Whitespace Philosophy
Nike's whitespace strategy is deliberately aggressive — not in the luxurious, breathing way of a fashion brand, but in a compressed, high-density way that fills every pixel with either content or intentional absence. Product grids use minimal gaps (4-12px) to create a sense of abundance and choice. Section breaks are generous (48-80px) to separate shopping contexts. The overall effect is a store that feels packed with product while remaining navigable — like a well-organized athletic superstore.
### Border Radius Scale
| Value | Context |
|-------|---------|
| 0px | Product images, hero photography (sharp edges) |
| 8px | Form inputs (non-search) |
| 18px | Small interactive elements |
| 20px | Containers, cards with UI content |
| 24px | Search inputs, medium pills |
| 30px | Buttons, tags, filters (full pill) |
| 50% | Circular icon buttons, avatar placeholders |
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat | No shadow, no border | Default state for everything |
| Divider | `0px -1px 0px 0px #E5E5E5 inset` | Subtle inset line between sections |
| Focus | `0 0 0 2px rgba(39, 93, 197, 1)` | Keyboard focus ring |
| Overlay | Dark scrim over photography | Text-on-image legibility |
Nike's elevation philosophy is radically flat. There are no card shadows, no hover lifts, no floating elements. Depth is communicated exclusively through color — dark sections recede, light sections advance, grey shifts indicate state changes. This flatness reinforces the athletic, no-nonsense brand personality: no visual frills, just direct communication. The only "shadow" in the entire system is a 1px inset divider line and the accessibility-required focus ring.
### Decorative Depth
- **Hero photography overlays**: Dark gradient scrims over full-bleed photography for text readability
- **Product background gradients**: Colored backgrounds behind hero product shots (e.g., red shoe on red gradient)
- **Banner bars**: Solid dark (#111111) promotional strips at page top
## 7. Do's and Don'ts
### Do
- Use Nike Black (#111111) for all primary text — never pure #000000
- Keep buttons pill-shaped (30px radius) and limited to primary/secondary variants
- Use full-bleed, edge-to-edge photography for hero sections — no border radius on images
- Let product photography provide all color vibrancy; keep UI monochromatic
- Use uppercase Nike Futura ND ONLY for display headlines (96px+)
- Maintain tight product grid gaps (4-12px) for a dense, abundant feel
- Use Grey-100 (#F5F5F5) for all input and placeholder backgrounds
- Reserve color exclusively for semantic meaning (red=error, green=success, blue=link)
- Use weight 500 (Medium) for all interactive text elements
### Don't
- Don't add shadows to cards — Nike's elevation model is entirely flat
- Don't use border radius on product imagery — only UI elements get rounded corners
- Don't introduce brand colors beyond the grey scale for UI elements
- Don't use Nike Futura ND below 24px — it's exclusively a display face
- Don't add hover lift effects — Nike cards don't animate on hover
- Don't use regular weight (400) for buttons or links — always use 500
- Don't place colored backgrounds behind UI elements — color is reserved for product contexts
- Don't use more than two levels of text hierarchy per card (title + body)
- Don't add decorative dividers — the 1px inset is the only divider pattern
- Don't soften the contrast — Nike's design deliberately pushes black-on-white to maximum
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | <640px | Single column, hamburger nav, display text scales down, tight 16px padding |
| Small Tablet | 640-768px | 2-column product grid begins, nav still collapsed |
| Tablet | 768-960px | 2-column grids, category cards scale, horizontal padding 24px |
| Small Desktop | 960-1024px | Nav expands to full horizontal, 3-column product grid |
| Desktop | 1024-1440px | Full layout, expanded nav, 3-column grids, 48px padding |
| Large Desktop | >1440px | Max-width container centered, increased margins, hero images full-bleed |
### Touch Targets
- Minimum touch target: 44x44px (WCAG AAA)
- Mobile nav icons: 48x48px touch area
- Product cards: full surface is tappable
- Filter pills: minimum 36px height with 12px padding
### Collapsing Strategy
- **Navigation**: Full category links → hamburger menu below 960px; search, favorites, cart icons remain visible
- **Product grids**: 3-col → 2-col at 960px → 1-col at 640px
- **Hero sections**: Display text scales from 96px → 64px → 48px; hero images remain full-bleed at all sizes
- **Category cards**: 3-col → 2-col → 1-col with maintained full-bleed imagery
- **Section padding**: 80px → 48px → 32px → 24px as viewport narrows
- **Promotional banner**: text wraps or truncates, maintains dark background
### Image Behavior
- Responsive images via Nike CDN (`c.static-nike.com`) with width parameters
- Product images: srcset with multiple resolutions (w_320, w_640, w_960, w_1920)
- Hero images: full-bleed at all breakpoints, aspect ratio shifts (16:9 desktop → 4:3 mobile)
- Lazy loading: native loading="lazy", grey-100 placeholder during load
- Art direction: hero crops change between desktop and mobile compositions

- Link: Link Blue (`#1151FF`)
### Example Component Prompts
- "Create a product hero section with full-bleed edge-to-edge photography, no border radius, a dark gradient overlay for text, and a massive uppercase 96px/500 headline in Nike Futura style with 0.90 line-height and a Nike Black (#111111) pill button (30px radius)"
- "Design a 3-column product card grid with square images (no border radius), 4px gap between cards, product name in 16px/500 Nike Black (#111111), price in 14px/500, and secondary text in Grey-500 (#707072)"
- "Build a sticky white navigation bar with a left-aligned logo, centered category links in 16px/500 (#111111) with hover color #707072, and right-aligned search (24px radius, #F5F5F5 background), favorites, and cart icons"
- "Create a promotional banner strip with #111111 background, white 12px/500 centered text, and 8px vertical padding — full width, no border radius"
- "Design a secondary outlined button with transparent background, 1.5px #CACACB border, 30px pill radius, 16px/500 #111111 text, hover border darkening to #707072"
### Iteration Guide
When refining existing screens generated with this design system:
1. Focus on ONE component at a time
2. Reference specific color names and hex codes from this document
3. Remember: product photography is the color — UI stays monochromatic
4. Use the grey scale for state changes: #F5F5F5 → #E5E5E5 → #CACACB → #707072
5. If something feels too colorful in the UI, it probably is — Nike keeps UI greyscale
6. Display type (Nike Futura) should ALWAYS be uppercase and never below 24px
7. Body type (Helvetica Now) should almost always be weight 500 for interactive elements

# Design System Inspired by Notion
> Category: Productivity & SaaS
> All-in-one workspace. Warm minimalism, serif headings, soft surfaces.
## 1. Visual Theme & Atmosphere
Notion's website embodies the philosophy of the tool itself: a blank canvas that gets out of your way. The design system is built on warm neutrals rather than cold grays, creating a distinctly approachable minimalism that feels like quality paper rather than sterile glass. The page canvas is pure white (`#ffffff`) but the text isn't pure black -- it's a warm near-black (`rgba(0,0,0,0.95)`) that softens the reading experience imperceptibly. The warm gray scale (`#f6f5f4`, `#31302e`, `#615d59`, `#a39e98`) carries subtle yellow-brown undertones, giving the interface a tactile, almost analog warmth.
The custom NotionInter font (a modified Inter) is the backbone of the system. At display sizes (64px), it uses aggressive negative letter-spacing (-2.125px), creating headlines that feel compressed and precise. The weight range is broader than typical systems: 400 for body, 500 for UI elements, 600 for semi-bold labels, and 700 for display headings. OpenType features `"lnum"` (lining numerals) and `"locl"` (localized forms) are enabled on larger text, adding typographic sophistication that rewards close reading.
What makes Notion's visual language distinctive is its border philosophy. Rather than heavy borders or shadows, Notion uses ultra-thin `1px solid rgba(0,0,0,0.1)` borders -- borders that exist as whispers, barely perceptible division lines that create structure without weight. The shadow system is equally restrained: multi-layer stacks with cumulative opacity never exceeding 0.05, creating depth that's felt rather than seen.
**Key Characteristics:**
- NotionInter (modified Inter) with negative letter-spacing at display sizes (-2.125px at 64px)
- Warm neutral palette: grays carry yellow-brown undertones (`#f6f5f4` warm white, `#31302e` warm dark)
- Near-black text via `rgba(0,0,0,0.95)` -- not pure black, creating micro-warmth
- Ultra-thin borders: `1px solid rgba(0,0,0,0.1)` throughout -- whisper-weight division
- Multi-layer shadow stacks with sub-0.05 opacity for barely-there depth
- Notion Blue (`#0075de`) as the singular accent color for CTAs and interactive elements
- Pill badges (9999px radius) with tinted blue backgrounds for status indicators
- 8px base spacing unit with an organic, non-rigid scale
## 2. Color Palette & Roles
### Primary
- **Notion Black** (`rgba(0,0,0,0.95)` / `#000000f2`): Primary text, headings, body copy. The 95% opacity softens pure black without sacrificing readability.
- **Pure White** (`#ffffff`): Page background, card surfaces, button text on blue.
- **Notion Blue** (`#0075de`): Primary CTA, link color, interactive accent -- the only saturated color in the core UI chrome.
### Brand Secondary
- **Deep Navy** (`#213183`): Secondary brand color, used sparingly for emphasis and dark feature sections.
- **Active Blue** (`#005bab`): Button active/pressed state -- darker variant of Notion Blue.
### Warm Neutral Scale
- **Warm White** (`#f6f5f4`): Background surface tint, section alternation, subtle card fill. The yellow undertone is key.
- **Warm Dark** (`#31302e`): Dark surface background, dark section text. Warmer than standard grays.
- **Warm Gray 500** (`#615d59`): Secondary text, descriptions, muted labels.
- **Warm Gray 300** (`#a39e98`): Placeholder text, disabled states, caption text.
### Semantic Accent Colors
- **Teal** (`#2a9d99`): Success states, positive indicators.
- **Green** (`#1aae39`): Confirmation, completion badges.
- **Orange** (`#dd5b00`): Warning states, attention indicators.
- **Pink** (`#ff64c8`): Decorative accent, feature highlights.
- **Purple** (`#391c57`): Premium features, deep accents.
- **Brown** (`#523410`): Earthy accent, warm feature sections.
### Interactive
- **Link Blue** (`#0075de`): Primary link color with underline-on-hover.
- **Link Light Blue** (`#62aef0`): Lighter link variant for dark backgrounds.
- **Focus Blue** (`#097fe8`): Focus ring on interactive elements.
- **Badge Blue Bg** (`#f2f9ff`): Pill badge background, tinted blue surface.
- **Badge Blue Text** (`#097fe8`): Pill badge text, darker blue for readability.
### Shadows & Depth
- **Card Shadow** (`rgba(0,0,0,0.04) 0px 4px 18px, rgba(0,0,0,0.027) 0px 2.025px 7.84688px, rgba(0,0,0,0.02) 0px 0.8px 2.925px, rgba(0,0,0,0.01) 0px 0.175px 1.04062px`): Multi-layer card elevation.
- **Deep Shadow** (`rgba(0,0,0,0.01) 0px 1px 3px, rgba(0,0,0,0.02) 0px 3px 7px, rgba(0,0,0,0.02) 0px 7px 15px, rgba(0,0,0,0.04) 0px 14px 28px, rgba(0,0,0,0.05) 0px 23px 52px`): Five-layer deep elevation for modals and featured content.
- **Whisper Border** (`1px solid rgba(0,0,0,0.1)`): Standard division border -- cards, dividers, sections.
## 3. Typography Rules
### Font Family
- **Primary**: `NotionInter`, with fallbacks: `Inter, -apple-system, system-ui, Segoe UI, Helvetica, Apple Color Emoji, Arial, Segoe UI Emoji, Segoe UI Symbol`
- **OpenType Features**: `"lnum"` (lining numerals) and `"locl"` (localized forms) enabled on display and heading text.
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display Hero | NotionInter | 64px (4.00rem) | 700 | 1.00 (tight) | -2.125px | Maximum compression, billboard headlines |
| Display Secondary | NotionInter | 54px (3.38rem) | 700 | 1.04 (tight) | -1.875px | Secondary hero, feature headlines |
| Section Heading | NotionInter | 48px (3.00rem) | 700 | 1.00 (tight) | -1.5px | Feature section titles, with `"lnum"` |
| Sub-heading Large | NotionInter | 40px (2.50rem) | 700 | 1.50 | normal | Card headings, feature sub-sections |
| Sub-heading | NotionInter | 26px (1.63rem) | 700 | 1.23 (tight) | -0.625px | Section sub-titles, content headers |
| Card Title | NotionInter | 22px (1.38rem) | 700 | 1.27 (tight) | -0.25px | Feature cards, list titles |
| Body Large | NotionInter | 20px (1.25rem) | 600 | 1.40 | -0.125px | Introductions, feature descriptions |
| Body | NotionInter | 16px (1.00rem) | 400 | 1.50 | normal | Standard reading text |
| Body Medium | NotionInter | 16px (1.00rem) | 500 | 1.50 | normal | Navigation, emphasized UI text |
| Body Semibold | NotionInter | 16px (1.00rem) | 600 | 1.50 | normal | Strong labels, active states |
| Body Bold | NotionInter | 16px (1.00rem) | 700 | 1.50 | normal | Headlines at body size |
| Nav / Button | NotionInter | 15px (0.94rem) | 600 | 1.33 | normal | Navigation links, button text |
| Caption | NotionInter | 14px (0.88rem) | 500 | 1.43 | normal | Metadata, secondary labels |
| Caption Light | NotionInter | 14px (0.88rem) | 400 | 1.43 | normal | Body captions, descriptions |
| Badge | NotionInter | 12px (0.75rem) | 600 | 1.33 | 0.125px | Pill badges, tags, status labels |
| Micro Label | NotionInter | 12px (0.75rem) | 400 | 1.33 | 0.125px | Small metadata, timestamps |
### Principles
- **Compression at scale**: NotionInter at display sizes uses -2.125px letter-spacing at 64px, progressively relaxing to -0.625px at 26px and normal at 16px. The compression creates density at headlines while maintaining readability at body sizes.
- **Four-weight system**: 400 (body/reading), 500 (UI/interactive), 600 (emphasis/navigation), 700 (headings/display). The broader weight range compared to most systems allows nuanced hierarchy.
- **Warm scaling**: Line height tightens as size increases -- 1.50 at body (16px), 1.23-1.27 at sub-headings, 1.00-1.04 at display. This creates denser, more impactful headlines.
- **Badge micro-tracking**: The 12px badge text uses positive letter-spacing (0.125px) -- the only positive tracking in the system, creating wider, more legible small text.

- Warm white (`#f6f5f4`) background variant for alternating sections
**Trust Bar / Logo Grid**
- Company logos (trusted teams section) in their brand colors
- Horizontal scroll or grid layout with team counts
- Metric display: large number + description pattern
**Metric Cards**
- Large number display (e.g., "$4,200 ROI")
- NotionInter 40px+ weight 700 for the metric
- Description below in warm gray body text
- Whisper-bordered card container
## 5. Layout Principles
### Spacing System
- Base unit: 8px
- Scale: 2px, 3px, 4px, 5px, 6px, 7px, 8px, 11px, 12px, 14px, 16px, 24px, 32px
- Non-rigid organic scale with fractional values (5.6px, 6.4px) for micro-adjustments
### Grid & Container
- Max content width: approximately 1200px
- Hero: centered single-column with generous top padding (80-120px)
- Feature sections: 2-3 column grids for cards
- Full-width warm white (`#f6f5f4`) section backgrounds for alternation
- Code/dashboard screenshots as contained with whisper border
### Whitespace Philosophy
- **Generous vertical rhythm**: 64-120px between major sections. Notion lets content breathe with vast vertical padding.
- **Warm alternation**: White sections alternate with warm white (`#f6f5f4`) sections, creating gentle visual rhythm without harsh color breaks.
- **Content-first density**: Body text blocks are compact (line-height 1.50) but surrounded by ample margin, creating islands of readable content in a sea of white space.
### Border Radius Scale
- Micro (4px): Buttons, inputs, functional interactive elements
- Subtle (5px): Links, list items, menu items
- Standard (8px): Small cards, containers, inline elements
- Comfortable (12px): Standard cards, feature containers, image tops
- Large (16px): Hero cards, featured content, promotional blocks
- Full Pill (9999px): Badges, pills, status indicators
- Circle (100%): Tab indicators, avatars
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow, no border | Page background, text blocks |
| Whisper (Level 1) | `1px solid rgba(0,0,0,0.1)` | Standard borders, card outlines, dividers |
| Soft Card (Level 2) | 4-layer shadow stack (max opacity 0.04) | Content cards, feature blocks |
| Deep Card (Level 3) | 5-layer shadow stack (max opacity 0.05, 52px blur) | Modals, featured panels, hero elements |
| Focus (Accessibility) | `2px solid var(--focus-color)` outline | Keyboard focus on all interactive elements |
**Shadow Philosophy**: Notion's shadow system uses multiple layers with extremely low individual opacity (0.01 to 0.05) that accumulate into soft, natural-looking elevation. The 4-layer card shadow spans from 1.04px to 18px blur, creating a gradient of depth rather than a single hard shadow. The 5-layer deep shadow extends to 52px blur at 0.05 opacity, producing ambient occlusion that feels like natural light rather than computer-generated depth. This layered approach makes elements feel embedded in the page rather than floating above it.
### Decorative Depth
- Hero section: decorative character illustrations (playful, hand-drawn style)
- Section alternation: white to warm white (`#f6f5f4`) background shifts
- No hard section borders -- separation comes from background color changes and spacing
## 7. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile Small | <400px | Tight single column, minimal padding |
| Mobile | 400-600px | Standard mobile, stacked layout |
| Tablet Small | 600-768px | 2-column grids begin |
| Tablet | 768-1080px | Full card grids, expanded padding |
| Desktop Small | 1080-1200px | Standard desktop layout |
| Desktop | 1200-1440px | Full layout, maximum content width |
| Large Desktop | >1440px | Centered, generous margins |
### Touch Targets
- Buttons use comfortable padding (8px-16px vertical)
- Navigation links at 15px with adequate spacing
- Pill badges have 8px horizontal padding for tap targets
- Mobile menu toggle uses standard hamburger button
### Collapsing Strategy
- Hero: 64px display -> scales to 40px -> 26px on mobile, maintains proportional letter-spacing
- Navigation: horizontal links + blue CTA -> hamburger menu
- Feature cards: 3-column -> 2-column -> single column stacked
- Product screenshots: maintain aspect ratio with responsive images
- Trust bar logos: grid -> horizontal scroll on mobile
- Footer: multi-column -> stacked single column
- Section spacing: 80px+ -> 48px on mobile
### Image Behavior
- Workspace screenshots maintain whisper border at all sizes
- Hero illustrations scale proportionally
- Product screenshots use responsive images with consistent border radius
- Full-width warm white sections maintain edge-to-edge treatment
## 8. Accessibility & States
### Focus System
- All interactive elements receive visible focus indicators
- Focus outline: `2px solid` with focus color + shadow level 200
- Tab navigation supported throughout all interactive components
- High contrast text: near-black on white exceeds WCAG AAA (>14:1 ratio)
### Interactive States
- **Default**: Standard appearance with whisper borders
- **Hover**: Color shift on text, scale(1.05) on buttons, underline on links
- **Active/Pressed**: scale(0.9) transform, darker background variant
- **Focus**: Blue outline ring with shadow reinforcement
- **Disabled**: Warm gray (`#a39e98`) text, reduced opacity
### Color Contrast
- Primary text (rgba(0,0,0,0.95)) on white: ~18:1 ratio
- Secondary text (#615d59) on white: ~5.5:1 ratio (WCAG AA)
- Blue CTA (#0075de) on white: ~4.6:1 ratio (WCAG AA for large text)
- Badge text (#097fe8) on badge bg (#f2f9ff): ~4.5:1 ratio (WCAG AA for large text)
## 9. Agent Prompt Guide
### Quick Color Reference
- Primary CTA: Notion Blue (`#0075de`)
- Background: Pure White (`#ffffff`)
- Alt Background: Warm White (`#f6f5f4`)
- Heading text: Near-Black (`rgba(0,0,0,0.95)`)
- Body text: Near-Black (`rgba(0,0,0,0.95)`)

### Example Component Prompts
- "Create a hero section on white background. Headline at 64px NotionInter weight 700, line-height 1.00, letter-spacing -2.125px, color rgba(0,0,0,0.95). Subtitle at 20px weight 600, line-height 1.40, color #615d59. Blue CTA button (#0075de, 4px radius, 8px 16px padding, white text) and ghost button (transparent bg, near-black text, underline on hover)."
- "Design a card: white background, 1px solid rgba(0,0,0,0.1) border, 12px radius. Use shadow stack: rgba(0,0,0,0.04) 0px 4px 18px, rgba(0,0,0,0.027) 0px 2.025px 7.85px, rgba(0,0,0,0.02) 0px 0.8px 2.93px, rgba(0,0,0,0.01) 0px 0.175px 1.04px.

- "Design an alternating section layout: white sections alternate with warm white (#f6f5f4) sections. Each section has 64-80px vertical padding, max-width 1200px centered. Section heading at 48px weight 700, line-height 1.00, letter-spacing -1.5px."
### Iteration Guide
1. Always use warm neutrals -- Notion's grays have yellow-brown undertones (#f6f5f4, #31302e, #615d59, #a39e98), never blue-gray
2. Letter-spacing scales with font size: -2.125px at 64px, -1.875px at 54px, -0.625px at 26px, normal at 16px
3. Four weights: 400 (read), 500 (interact), 600 (emphasize), 700 (announce)
4. Borders are whispers: 1px solid rgba(0,0,0,0.1) -- never heavier
5. Shadows use 4-5 layers with individual opacity never exceeding 0.05
6. The warm white (#f6f5f4) section background is essential for visual rhythm
7. Pill badges (9999px) for status/tags, 4px radius for buttons and inputs
8. Notion Blue (#0075de) is the only saturated color in core UI -- use it sparingly for CTAs and links

# Design System Inspired by NVIDIA
> Category: Media & Consumer
> GPU computing. Green-black energy, technical power aesthetic.
## 1. Visual Theme & Atmosphere
NVIDIA's website is a high-contrast, technology-forward experience that communicates raw computational power through design restraint. The page is built on a stark black (`#000000`) and white (`#ffffff`) foundation, punctuated by NVIDIA's signature green (`#76b900`) -- a color so specific it functions as a brand fingerprint. This is not the lush green of nature; it's the electric, lime-shifted green of GPU-rendered light, a color that sits between chartreuse and kelly green and immediately signals "NVIDIA" to anyone in technology.
The custom NVIDIA-EMEA font family (with Arial and Helvetica fallbacks) creates a clean, industrial typographic voice. Headings at 36px bold with tight 1.25 line-height create dense, authoritative blocks of text. The font lacks the geometric playfulness of Silicon Valley sans-serifs -- it's European, pragmatic, and engineering-focused. Body text runs at 15-16px, comfortable for reading but not generous, maintaining the sense that screen real estate is optimized like GPU memory.
What distinguishes NVIDIA's design from other dark-background tech sites is the disciplined use of the green accent. The `#76b900` appears in borders (`2px solid #76b900`), link underlines (`underline 2px rgb(118, 185, 0)`), and CTAs -- but never as backgrounds or large surface areas on the main content. The green is a signal, not a surface. Combined with a deep shadow system (`rgba(0, 0, 0, 0.3) 0px 0px 5px`) and minimal border radius (1-2px), the overall effect is of precision engineering hardware rendered in pixels.
**Key Characteristics:**
- NVIDIA Green (`#76b900`) as pure accent -- borders, underlines, and interactive highlights only
- Black (`#000000`) dominant background with white (`#ffffff`) text on dark sections
- NVIDIA-EMEA custom font with Arial/Helvetica fallback -- industrial, European, clean
- Tight line-heights (1.25 for headings) creating dense, authoritative text blocks
- Minimal border radius (1-2px) -- sharp, engineered corners throughout
- Green-bordered buttons (`2px solid #76b900`) as primary interactive pattern
- Font Awesome 6 Pro/Sharp icon system at weight 900 for sharp iconography
- Multi-framework architecture (PrimeReact, Fluent UI, Element Plus) enabling rich interactive components
## 2. Color Palette & Roles
### Primary Brand

- **Link Default (light bg)** (`#000000`): Black links with green underline on light backgrounds.
- **Link Hover** (`#3860be`): Blue shift on hover across all link variants.
- **Button Hover** (`#1eaedb`): Teal highlight for button hover states.
- **Button Active** (`#007fff`): Bright blue for active/pressed button states.
- **Focus Ring** (`#000000 solid 2px`): Black outline for keyboard focus.
### Shadows & Depth
- **Card Shadow** (`rgba(0, 0, 0, 0.3) 0px 0px 5px 0px`): Subtle ambient shadow for elevated cards.
## 3. Typography Rules
### Font Family
- **Primary**: `NVIDIA-EMEA`, with fallbacks: `Arial, Helvetica, sans-serif`
- **Icon Font**: `Font Awesome 6 Pro` (weight 900 for solid icons, 700 for regular)
- **Icon Sharp**: `Font Awesome 6 Sharp` (weight 300 for light icons, 400 for regular)
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |

| Body Small Bold | NVIDIA-EMEA | 15px (0.94rem) | 700 | 1.50 | normal | Emphasized secondary content |
| Button Large | NVIDIA-EMEA | 18px (1.13rem) | 700 | 1.25 (tight) | normal | Primary CTA buttons |
| Button | NVIDIA-EMEA | 16px (1.00rem) | 700 | 1.25 (tight) | normal | Standard buttons |
| Button Compact | NVIDIA-EMEA | 14.4px (0.90rem) | 700 | 1.00 (tight) | 0.144px | Small/compact buttons |
| Link | NVIDIA-EMEA | 14px (0.88rem) | 700 | 1.43 | normal | Navigation links |
| Link Uppercase | NVIDIA-EMEA | 14px (0.88rem) | 700 | 1.43 | normal | `text-transform: uppercase`, nav labels |
| Caption | NVIDIA-EMEA | 14px (0.88rem) | 600 | 1.50 | normal | Metadata, timestamps |
| Caption Small | NVIDIA-EMEA | 12px (0.75rem) | 400 | 1.25 (tight) | normal | Fine print, legal |
| Micro Label | NVIDIA-EMEA | 10px (0.63rem) | 700 | 1.50 | normal | `text-transform: uppercase`, tiny badges |
| Micro | NVIDIA-EMEA | 11px (0.69rem) | 700 | 1.00 (tight) | normal | Smallest UI text |
### Principles
- **Bold as the default voice**: NVIDIA leans heavily on weight 700 for headings, buttons, links, and labels. The 400 weight is reserved for body text and descriptions -- everything else is bold, projecting confidence and authority.
- **Tight headings, relaxed body**: Heading line-height is consistently 1.25 (tight), while body text relaxes to 1.50-1.67. This contrast creates visual density at the top of content blocks and comfortable readability in paragraphs.
- **Uppercase for navigation**: Link labels use `text-transform: uppercase` with weight 700, creating a navigation voice that reads like hardware specification labels.
- **No decorative tracking**: Letter-spacing is normal throughout, except for compact buttons (0.144px). The font itself carries the industrial character without manipulation.
## 4. Component Stylings
### Buttons
**Primary (Green Border)**
- Background: `transparent`

- Logo left-aligned, prominent NVIDIA wordmark
- Links: NVIDIA-EMEA 14px weight 700 uppercase, `#ffffff`
- Hover: color shift, no underline change
- Mega-menu dropdowns for product categories
- Sticky on scroll with backdrop
### Image Treatment
- Product/GPU renders as hero images, often full-width
- Screenshot images with subtle shadow for depth
- Green gradient overlays on dark hero sections
- Circular avatar containers with 50% radius
### Distinctive Components
**Product Cards**
- Clean white or dark card with minimal radius (2px)
- Green accent border or underline on title
- Bold heading + lighter description pattern
- CTA with green border at bottom
**Tech Spec Tables**
- Industrial grid layouts
- Alternating row backgrounds (subtle gray shift)
- Bold labels, regular values
- Green highlights for key metrics
**Cookie/Consent Banner**
- Fixed bottom positioning
- Rounded buttons (2px radius)
- Gray border treatments
## 5. Layout Principles
### Spacing System
- Base unit: 8px
- Scale: 1px, 2px, 3px, 4px, 5px, 6px, 7px, 8px, 9px, 10px, 11px, 12px, 13px, 15px
- Primary padding values: 8px, 11px, 13px, 16px, 24px, 32px
- Section spacing: 48-80px vertical padding
### Grid & Container
- Max content width: approximately 1200px (contained)
- Full-width hero sections with contained text
- Feature sections: 2-3 column grids for product cards
- Single-column for article/blog content
- Sidebar layouts for documentation
### Whitespace Philosophy
- **Purposeful density**: NVIDIA uses tighter spacing than typical SaaS sites, reflecting the density of technical content. White space exists to separate concepts, not to create luxury emptiness.
- **Section rhythm**: Dark sections alternate with white sections, using background color (not just spacing) to separate content blocks.
- **Card density**: Product cards sit close together with 16-20px gaps, creating a catalog feel rather than a gallery feel.
### Border Radius Scale
- Micro (1px): Inline spans, tiny elements
- Standard (2px): Buttons, cards, containers, inputs -- the default for nearly everything
- Circle (50%): Avatar images, circular tab indicators
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Page backgrounds, inline text |
| Subtle (Level 1) | `rgba(0,0,0,0.3) 0px 0px 5px 0px` | Standard cards, modals |
| Border (Level 1b) | `1px solid #5e5e5e` | Content dividers, section borders |
| Green accent (Level 2) | `2px solid #76b900` | Active elements, CTAs, selected items |
| Focus (Accessibility) | `2px solid #000000` outline | Keyboard focus ring |
**Shadow Philosophy**: NVIDIA's depth system is minimal and utilitarian. There is essentially one shadow value -- a 5px ambient blur at 30% opacity -- used sparingly for cards and modals. The primary depth signal is not shadow but _color contrast_: black backgrounds next to white sections, green borders on black surfaces. This creates hardware-like visual layering where depth comes from material difference, not simulated light.
### Decorative Depth
- Green gradient washes behind hero content
- Dark-to-darker gradients (black to near-black) for section transitions
- No glassmorphism or blur effects -- clarity over atmosphere
## 7. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile Small | <375px | Compact single column, reduced padding |
| Mobile | 375-425px | Standard mobile layout |
| Mobile Large | 425-600px | Wider mobile, some 2-col hints |
| Tablet Small | 600-768px | 2-column grids begin |
| Tablet | 768-1024px | Full card grids, expanded nav |
| Desktop | 1024-1350px | Standard desktop layout |
| Large Desktop | >1350px | Maximum content width, generous margins |
### Touch Targets
- Buttons use 11px 13px padding for comfortable tap targets
- Navigation links at 14px uppercase with adequate spacing
- Green-bordered buttons provide high-contrast touch targets on dark backgrounds
- Mobile: hamburger menu collapse with full-screen overlay
### Collapsing Strategy
- Hero: 36px heading scales down proportionally
- Navigation: full horizontal nav collapses to hamburger menu at ~1024px
- Product cards: 3-column to 2-column to single column stacked
- Footer: multi-column grid collapses to single stacked column
- Section spacing: 64-80px reduces to 32-48px on mobile
- Images: maintain aspect ratio, scale to container width
### Image Behavior
- GPU/product renders maintain high resolution at all sizes
- Hero images scale proportionally with viewport
- Card images use consistent aspect ratios
- Full-bleed dark sections maintain edge-to-edge treatment
## 8. Responsive Behavior (Extended)
### Typography Scaling
- Display 36px scales to ~24px on mobile
- Section headings 24px scale to ~20px on mobile
- Body text maintains 15-16px across all breakpoints
- Button text maintains 16px for consistent tap targets
### Dark/Light Section Strategy
- Dark sections (black bg, white text) alternate with light sections (white bg, black text)
- The green accent remains consistent across both surface types
- On dark: links are white, underlines are green
- On light: links are black, underlines are green
- This alternation creates natural scroll rhythm and content grouping
## 9. Agent Prompt Guide
### Quick Color Reference
- Primary accent: NVIDIA Green (`#76b900`)
- Background dark: True Black (`#000000`)
- Background light: Pure White (`#ffffff`)
- Heading text (dark bg): White (`#ffffff`)
- Heading text (light bg): Black (`#000000`)
- Body text (light bg): Black (`#000000`) or Near Black (`#1a1a1a`)
- Body text (dark bg): White (`#ffffff`) or Gray 300 (`#a7a7a7`)
- Link hover: Blue (`#3860be`)
- Border accent: `2px solid #76b900`
- Button hover: Teal (`#1eaedb`)
### Example Component Prompts
- "Create a hero section on black background. Headline at 36px NVIDIA-EMEA weight 700, line-height 1.25, color #ffffff. Subtitle at 18px weight 400, line-height 1.67, color #a7a7a7. CTA button with transparent background, 2px solid #76b900 border, 2px radius, 11px 13px padding, text #ffffff. Hover: background #1eaedb, text white."
- "Design a product card: white background, 2px border-radius, box-shadow rgba(0,0,0,0.3) 0px 0px 5px. Title at 20px NVIDIA-EMEA weight 700, line-height 1.25, color #000000. Body at 15px weight 400, line-height 1.67, color #757575. Green underline accent on title: border-bottom 2px solid #76b900."
- "Build a navigation bar: #000000 background, sticky top. NVIDIA logo left-aligned. Links at 14px NVIDIA-EMEA weight 700 uppercase, color #ffffff. Hover: color #3860be. Green-bordered CTA button right-aligned."
- "Create a dark feature section: #000000 background. Section label at 14px weight 700 uppercase, color #76b900. Heading at 24px weight 700, color #ffffff. Description at 16px weight 400, color #a7a7a7. Three product cards in a row with 20px gap."
- "Design a footer: #000000 background. Multi-column layout with link groups. Links at 14px weight 400, color #a7a7a7. Hover: color #76b900. Bottom bar with legal text at 12px, color #757575."
### Iteration Guide
1. Always use `#76b900` as accent, never as a background fill -- it's a signal color for borders, underlines, and highlights
2. Buttons are transparent with green borders by default -- filled backgrounds appear only on hover/active states
3. Weight 700 is the dominant voice for all interactive and heading elements; 400 is only for body paragraphs
4. Border radius is 2px for everything -- this sharp, minimal rounding is core to the industrial aesthetic
5. Dark sections use white text; light sections use black text -- green accent works identically on both
6. Link hover is always `#3860be` (blue) regardless of the link's default color
7. Line-height 1.25 for headings, 1.50-1.67 for body text -- maintain this contrast for visual hierarchy
8. Navigation uses uppercase 14px bold -- this hardware-label typography is part of the brand voice

# Design System Inspired by Ollama
> Category: AI & LLM
> Run LLMs locally. Terminal-first, monochrome simplicity.
## 1. Visual Theme & Atmosphere
Ollama's interface is radical minimalism taken to its logical conclusion — a pure-white void where content floats without decoration, shadow, or color. The design philosophy mirrors the product itself: strip away everything unnecessary until only the essential tool remains. This is the digital equivalent of a Dieter Rams object — every pixel earns its place, and the absence of design IS the design.
The entire page exists in pure grayscale. There is zero chromatic color in the interface — no brand blue, no accent green, no semantic red. The only colors that exist are shades between pure black (`#000000`) and pure white (`#ffffff`), creating a monochrome environment that lets the user's mental model of "open models" remain uncolored by brand opinion. The Ollama llama mascot, rendered in simple black line art, is the only illustration — and even it's monochrome.
What makes Ollama distinctive is the combination of SF Pro Rounded (Apple's rounded system font) with an exclusively pill-shaped geometry (9999px radius on everything interactive). The rounded letterforms + rounded buttons + rounded containers create a cohesive "softness language" that makes a developer CLI tool feel approachable and friendly rather than intimidating. This is minimalism with warmth — not cold Swiss-style grid minimalism, but the kind where the edges are literally softened.
**Key Characteristics:**
- Pure white canvas with zero chromatic color — completely grayscale
- SF Pro Rounded headlines creating a distinctively Apple-like softness
- Binary border-radius system: 12px (containers) or 9999px (everything interactive)
- Zero shadows — depth comes exclusively from background color shifts and borders
- Pill-shaped geometry on all interactive elements (buttons, tabs, inputs, tags)
- The Ollama llama as the sole illustration — black line art, no color
- Extreme content restraint — the homepage is short, focused, and uncluttered
## 2. Color Palette & Roles
### Primary
- **Pure Black** (`#000000`): Primary headlines, primary links, and the darkest text. The only "color" that demands attention.
- **Near Black** (`#262626`): Button text on light surfaces, secondary headline weight.
- **Darkest Surface** (`#090909`): The darkest possible surface — barely distinguishable from pure black, used for footer or dark containers.
### Surface & Background
- **Pure White** (`#ffffff`): The primary page background — not off-white, not cream, pure white. Button surfaces for secondary actions.
- **Snow** (`#fafafa`): The subtlest possible surface distinction from white — used for section backgrounds and barely-elevated containers.
- **Light Gray** (`#e5e5e5`): Button backgrounds, borders, and the primary containment color. The workhorse neutral.
### Neutrals & Text
- **Stone** (`#737373`): Secondary body text, footer links, and de-emphasized content. The primary "muted" tone.
- **Mid Gray** (`#525252`): Emphasized secondary text, slightly darker than Stone.
- **Silver** (`#a3a3a3`): Tertiary text, placeholders, and deeply de-emphasized metadata.
- **Button Text Dark** (`#404040`): Specific to white-surface button text.
### Semantic & Accent
- **Ring Blue** (`#3b82f6` at 50%): The ONLY non-gray color in the entire system — Tailwind's default focus ring, used exclusively for keyboard accessibility. Never visible in normal interaction flow.
- **Border Light** (`#d4d4d4`): A slightly darker gray for white-surface button borders.
### Gradient System
- **None.** Ollama uses absolutely no gradients. Visual separation comes from flat color blocks and single-pixel borders. This is a deliberate, almost philosophical design choice.
## 3. Typography Rules
### Font Family
- **Display**: `SF Pro Rounded`, with fallbacks: `system-ui, -apple-system, system-ui`
- **Body / UI**: `ui-sans-serif`, with fallbacks: `system-ui, Apple Color Emoji, Segoe UI Emoji, Segoe UI Symbol, Noto Color Emoji`
- **Monospace**: `ui-monospace`, with fallbacks: `SFMono-Regular, Menlo, Monaco, Consolas, Liberation Mono, Courier New`
*Note: SF Pro Rounded is Apple's system font — it renders with rounded terminals on macOS/iOS and falls back to the system sans-serif on other platforms.*
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display / Hero | SF Pro Rounded | 48px (3rem) | 500 | 1.00 (tight) | normal | Maximum impact, rounded letterforms |
| Section Heading | SF Pro Rounded | 36px (2.25rem) | 500 | 1.11 (tight) | normal | Feature section titles |
| Sub-heading | SF Pro Rounded / ui-sans-serif | 30px (1.88rem) | 400–500 | 1.20 (tight) | normal | Card headings, feature names |
| Card Title | ui-sans-serif | 24px (1.5rem) | 400 | 1.33 | normal | Medium emphasis headings |
| Body Large | ui-sans-serif | 18px (1.13rem) | 400–500 | 1.56 | normal | Hero descriptions, button text |
| Body / Link | ui-sans-serif | 16px (1rem) | 400–500 | 1.50 | normal | Standard body text, navigation |
| Caption | ui-sans-serif | 14px (0.88rem) | 400 | 1.43 | normal | Metadata, descriptions |
| Small | ui-sans-serif | 12px (0.75rem) | 400 | 1.33 | normal | Smallest sans-serif text |
| Code Body | ui-monospace | 16px (1rem) | 400 | 1.50 | normal | Inline code, commands |
| Code Caption | ui-monospace | 14px (0.88rem) | 400 | 1.43 | normal | Code snippets, secondary |
| Code Small | ui-monospace | 12px (0.75rem) | 400–700 | 1.63 | normal | Tags, labels |
### Principles
- **Rounded display, standard body**: SF Pro Rounded carries display headlines with its distinctive rounded terminals, while the standard system sans handles all body text. The rounded font IS the brand expression.
- **Weight restraint**: Only two weights matter — 400 (regular) for body and 500 (medium) for headings. No bold, no light, no black weight. This extreme restraint reinforces the minimal philosophy.
- **Tight display, comfortable body**: Headlines compress to 1.0 line-height, while body text relaxes to 1.43–1.56. The contrast creates clear hierarchy without needing weight contrast.
- **Monospace for developer identity**: Code blocks and terminal commands appear throughout as primary content, using the system monospace stack.
## 4. Component Stylings
### Buttons
**Gray Pill (Primary)**
- Background: Light Gray (`#e5e5e5`)
- Text: Near Black (`#262626`)
- Padding: 10px 24px
- Border: thin solid Light Gray (`1px solid #e5e5e5`)
- Radius: pill-shaped (9999px)
- The primary action button — understated, grayscale, always pill-shaped
**White Pill (Secondary)**
- Background: Pure White (`#ffffff`)
- Text: Button Text Dark (`#404040`)
- Padding: 10px 24px
- Border: thin solid Border Light (`1px solid #d4d4d4`)
- Radius: pill-shaped (9999px)
- Secondary action — visually lighter than Gray Pill
**Black Pill (CTA)**
- Background: Pure Black (`#000000`)
- Text: Pure White (`#ffffff`)
- Radius: pill-shaped (9999px)
- Inferred from "Create account" and "Explore" buttons
- Maximum emphasis — black on white
### Cards & Containers
- Background: Pure White or Snow (`#fafafa`)
- Border: thin solid Light Gray (`1px solid #e5e5e5`) when needed
- Radius: comfortably rounded (12px) — the ONLY non-pill radius in the system
- Shadow: **none** — zero shadows on any element
- Hover: likely subtle background shift or border darkening
### Inputs & Forms
- Background: Pure White
- Border: `1px solid #e5e5e5`
- Radius: pill-shaped (9999px) — search inputs and form fields are pill-shaped
- Focus: Ring Blue (`#3b82f6` at 50%) ring
- Placeholder: Silver (`#a3a3a3`)
### Navigation
- Clean horizontal nav with minimal elements
- Logo: Ollama llama icon + wordmark in black
- Links: "Models", "Docs", "Pricing" in black at 16px, weight 400
- Search bar: pill-shaped with placeholder text
- Right side: "Sign in" link + "Download" black pill CTA
- No borders, no background — transparent nav on white page
### Image Treatment
- The Ollama llama mascot is the only illustration — black line art on white
- Code screenshots/terminal outputs shown in bordered containers (12px radius)
- Integration logos displayed as simple icons in a grid
- No photographs, no gradients, no decorative imagery
### Distinctive Components
**Tab Pills**
- Pill-shaped tab selectors (e.g., "Coding" | "OpenClaw")
- Active: Light Gray bg; Inactive: transparent
- All pill-shaped (9999px)
**Model Tags**
- Small pill-shaped tags (e.g., "ollama", "launch", "claude")
- Light Gray background, dark text
- The primary way to browse models
**Terminal Command Block**
- Monospace code showing `ollama run` commands
- Minimal styling — just a bordered 12px-radius container
- Copy button integrated
**Integration Grid**
- Grid of integration logos (Codex, Claude Code, OpenCode, LangChain, etc.)
- Each in a bordered pill or card with icon + name
- Tabbed by category (Coding, Documents & RAG, Automation, Chat)
## 5. Layout Principles
### Spacing System
- Base unit: 8px
- Scale: 4px, 6px, 8px, 9px, 10px, 12px, 14px, 16px, 20px, 24px, 32px, 40px, 48px, 88px, 112px
- Button padding: 10px 24px (consistent across all buttons)
- Card internal padding: approximately 24–32px
- Section vertical spacing: very generous (88px–112px)
### Grid & Container
- Max container width: approximately 1024–1280px, centered
- Hero: centered single-column with llama illustration
- Feature sections: 2-column layout (text left, code right)
- Integration grid: responsive multi-column
- Footer: clean single-row
### Whitespace Philosophy
- **Emptiness as luxury**: The page is remarkably short and sparse — no feature section overstays its welcome. Each concept gets minimal but sufficient space.
- **Content density is low by design**: Where other AI companies pack feature after feature, Ollama presents three ideas (run models, use with apps, integrations) and stops.
- **The white space IS the brand**: Pure white space with zero decoration communicates "this tool gets out of your way."
### Border Radius Scale
- Comfortably rounded (12px): The sole container radius — code blocks, cards, panels
- Pill-shaped (9999px): Everything interactive — buttons, tabs, inputs, tags, badges
*This binary system is extreme and distinctive. There is no 4px, no 8px, no gradient of roundness. Elements are either containers (12px) or interactive (pill).*
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow, no border | Page background, most content |
| Bordered (Level 1) | `1px solid #e5e5e5` | Cards, code blocks, buttons |
**Shadow Philosophy**: Ollama uses **zero shadows**. This is not an oversight — it's a deliberate design decision. Every other major AI product site uses at least subtle shadows. Ollama's flat, shadowless approach creates a paper-like experience where elements are distinguished purely by background color and single-pixel borders. Depth is communicated through **content hierarchy and typography weight**, not visual layering.
## 7. Do's and Don'ts
### Do
- Use pure white (`#ffffff`) as the page background — never off-white or cream
- Use pill-shaped (9999px) radius on all interactive elements — buttons, tabs, inputs, tags
- Use 12px radius on all non-interactive containers — code blocks, cards, panels
- Keep the palette strictly grayscale — no chromatic colors except the blue focus ring
- Use SF Pro Rounded at weight 500 for display headings — the rounded terminals are the brand expression
- Maintain zero shadows — depth comes from borders and background shifts only
- Keep content density low — each section should present one clear idea
- Use monospace for terminal commands and code — it's primary content, not decoration
- Keep all buttons at 10px 24px padding with pill shape — consistency is absolute
### Don't
- Don't introduce any chromatic color — no brand blue, no accent green, no warm tones
- Don't use border-radius between 12px and 9999px — the system is binary
- Don't add shadows to any element — the flat aesthetic is intentional
- Don't use font weights above 500 — no bold, no black weight
- Don't add decorative illustrations beyond the llama mascot
- Don't use gradients anywhere — flat blocks and borders only
- Don't overcomplicate the layout — two columns maximum, no complex grids
- Don't use borders heavier than 1px — containment is always the lightest possible touch
- Don't add hover animations or transitions — interactions should feel instant and direct
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | <640px | Single column, stacked everything, hamburger nav |
| Small Tablet | 640–768px | Minor adjustments to spacing |
| Tablet | 768–850px | 2-column layouts begin |
| Desktop | 850–1024px | Standard layout, expanded features |
| Large Desktop | 1024–1280px | Maximum content width |
### Touch Targets
- All buttons are pill-shaped with generous padding (10px 24px)
- Navigation links at comfortable 16px size
- Minimum touch area easily exceeds 44x44px
### Collapsing Strategy
- **Navigation**: Collapses to hamburger menu on mobile
- **Feature sections**: 2-column → stacked single column
- **Hero text**: 48px → 36px → 30px progressive scaling
- **Integration grid**: Multi-column → 2-column → single column
- **Code blocks**: Horizontal scroll maintained
### Image Behavior
- Llama mascot scales proportionally
- Code blocks maintain monospace formatting
- Integration icons reflow to fewer columns
- No art direction changes
## 9. Agent Prompt Guide
### Quick Color Reference
- Primary Text: "Pure Black (#000000)"
- Page Background: "Pure White (#ffffff)"
- Secondary Text: "Stone (#737373)"
- Button Background: "Light Gray (#e5e5e5)"
- Borders: "Light Gray (#e5e5e5)"
- Muted Text: "Silver (#a3a3a3)"
- Dark Text: "Near Black (#262626)"
- Subtle Surface: "Snow (#fafafa)"
### Example Component Prompts
- "Create a hero section on pure white (#ffffff) with an illustration centered above a headline at 48px SF Pro Rounded weight 500, line-height 1.0. Use Pure Black (#000000) text. Below, add a black pill-shaped CTA button (9999px radius, 10px 24px padding) and a gray pill button."
- "Design a code block with a 12px border-radius, 1px solid Light Gray (#e5e5e5) border on white background. Use ui-monospace at 16px for the terminal command. No shadow."
- "Build a tab bar with pill-shaped tabs (9999px radius). Active tab: Light Gray (#e5e5e5) background, Near Black (#262626) text. Inactive: transparent background, Stone (#737373) text."
- "Create an integration card grid. Each card is a bordered pill (9999px radius) or a 12px-radius card with 1px solid #e5e5e5 border. Icon + name inside. Grid of 4 columns on desktop."
- "Design a navigation bar: transparent background, no border. Ollama logo on the left, 3 text links (Pure Black, 16px, weight 400), pill search input in the center, 'Sign in' text link and black pill 'Download' button on the right."
### Iteration Guide
1. Focus on ONE component at a time
2. Keep all values grayscale — "Stone (#737373)" not "use a light color"
3. Always specify pill (9999px) or container (12px) radius — nothing in between
4. Shadows are always zero — never add them
5. Weight is always 400 or 500 — never bold
6. If something feels too decorated, remove it — less is always more for Ollama

# Design System Inspired by OpenAI
> Category: AI & LLM
> Calm, near-monochrome system anchored in deep teal-black with generous white space and editorial typography.
## 1. Visual Theme & Atmosphere
OpenAI's product surface reads like a research lab dressed for the public — clinical, restrained, deliberately quiet. The page background is a true white (`#ffffff`) layered against a near-black ink (`#0d0d0d`) with a subtle teal undertone, so even the text feels slightly cooled rather than aggressively dark. The result is a chromatic neutrality that puts model output, code, and prose front and center, not the chrome around them.
The signature move is the use of **Söhne** (or its system stand-in `inter`) at restrained weights — 400 for body, 500 for nav and labels, 600 for emphasis — paired with **Signifier**, a contemporary serif used for editorial display. Where most AI brands lean futuristic, OpenAI's serif headlines give the product a quietly literary tone, as if every announcement is an essay.
The shape system is uniformly soft: 8px–12px radii, 9999px pills for tags and chips, no harsh corners anywhere. Section transitions are denoted by whitespace rather than dividers; when borders appear they are `#e5e5e5` hairlines that read as the absence of color rather than its presence.
**Key Characteristics:**
- True white canvas (`#ffffff`) with deep teal-black ink (`#0d0d0d`)
- Söhne / Inter at modest weights (400, 500, 600) — restraint over assertion
- Signifier serif for editorial display headlines
- Soft 8–12px radii everywhere; 9999px pills for chips
- Hairline borders (`#e5e5e5`) used sparingly; whitespace as primary divider
- Single-color illustrations in deep teal — no gradients in marks
- Generous line-height (1.55–1.65) and tracking near zero
## 2. Color Palette & Roles
### Primary
- **Pure White** (`#ffffff`): Primary background, card surface, button background.
- **Ink Black** (`#0d0d0d`): Primary text, brand mark, primary CTA.
- **Soft Black** (`#1a1a1a`): Secondary heading, alternative ink for non-critical text.
### Surface & Background
- **Mist** (`#fafafa`): Section break background, footer surface.
- **Pearl** (`#f5f5f5`): Card surface, elevated panel.
- **Cloud** (`#ececec`): Disabled background, divider tint.
### Brand Accent
- **OpenAI Teal** (`#10a37f`): Brand primary, link, highlight badge — the lone color in an otherwise neutral system.
- **Teal Deep** (`#0a7a5e`): Hover and pressed state for the brand color.
- **Teal Soft** (`#e8f5f0`): Surface tint for success badges, highlight callouts.
### Neutrals & Text
- **Graphite** (`#3c3c3c`): Body text, default reading color.
- **Slate** (`#6e6e6e`): Secondary text, captions, metadata.
- **Ash** (`#9b9b9b`): Tertiary text, placeholder, disabled label.
- **Stone** (`#c4c4c4`): Decorative dividers, faint icons.
### Semantic & Border
- **Border Hairline** (`#e5e5e5`): Standard hairline separator.
- **Border Soft** (`#ededed`): Card outline on white surface.
- **Error** (`#ef4146`): Validation, destructive action.
- **Warning** (`#f5a623`): Soft amber for advisory states.
- **Info** (`#2563eb`): Informational link tone (used sparingly; teal still wins).
## 3. Typography Rules
### Font Family
- **Display / Editorial**: `Signifier`, with fallback: `'Source Serif Pro', Georgia, serif`
- **Body / UI**: `Söhne`, with fallback: `Inter, system-ui, -apple-system, 'Segoe UI', sans-serif`
- **Code / Mono**: `Söhne Mono`, with fallback: `ui-monospace, 'JetBrains Mono', Menlo, Consolas, monospace`
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display | Signifier | 56px (3.5rem) | 400 | 1.08 | -0.02em | Editorial hero, announcement titles |
| H1 | Söhne | 40px (2.5rem) | 600 | 1.15 | -0.01em | Page heading |
| H2 | Söhne | 28px (1.75rem) | 600 | 1.2 | -0.005em | Section heading |
| H3 | Söhne | 20px (1.25rem) | 600 | 1.3 | normal | Sub-section |
| Body Large | Söhne | 18px (1.125rem) | 400 | 1.6 | normal | Lede paragraphs |
| Body | Söhne | 16px (1rem) | 400 | 1.65 | normal | Standard reading text |
| Body Small | Söhne | 14px (0.875rem) | 400 | 1.55 | normal | Card body, dense UI |
| Caption | Söhne | 13px (0.8125rem) | 500 | 1.4 | 0.01em | Metadata, badges |
| Label | Söhne | 12px (0.75rem) | 500 | 1.3 | 0.04em | Eyebrow, uppercase nav links |
| Code | Söhne Mono | 14px (0.875rem) | 400 | 1.55 | normal | Code blocks, terminal output |
### Principles
- **Restraint as identity**: weights cap at 600; 700+ feels off-brand. Hierarchy comes from size and color, not weight.
- **Serif for soul, sans for system**: Signifier appears only in editorial display moments. The product UI is sans-only.
- **Negative tracking on display**: -0.02em on display sizes; tracking returns to zero by 16px.

# Design System Inspired by OpenCode
> Category: AI & LLM
> AI coding platform. Developer-centric dark theme.
## 1. Visual Theme & Atmosphere
OpenCode's website embodies a terminal-native, monospace-first aesthetic that reflects its identity as an open source AI coding agent. The entire visual system is built on a stark dark-on-light contrast using a near-black background (`#201d1d`) with warm off-white text (`#fdfcfc`). This isn't a generic dark theme -- it's a warm, slightly reddish-brown dark that feels like a sophisticated terminal emulator rather than a cold IDE. The warm undertone in both the darks and lights (notice the subtle red channel in `#201d1d` -- rgb(32, 29, 29)) creates a cohesive, lived-in quality.
Berkeley Mono is the sole typeface, establishing an unapologetic monospace identity. Every element -- headings, body text, buttons, navigation -- shares this single font family, creating a unified "everything is code" philosophy. The heading at 38px bold with 1.50 line-height is generous and readable, while body text at 16px with weight 500 provides a slightly heavier-than-normal reading weight that enhances legibility on screen. The monospace grid naturally enforces alignment and rhythm across the layout.
The color system is deliberately minimal. The primary palette consists of just three functional tones: the warm near-black (`#201d1d`), a medium warm gray (`#9a9898`), and a bright off-white (`#fdfcfc`). Semantic colors borrow from the Apple HIG palette -- blue accent (`#007aff`), red danger (`#ff3b30`), green success (`#30d158`), orange warning (`#ff9f0a`) -- giving the interface familiar, trustworthy signal colors without adding brand complexity. Borders use a subtle warm transparency (`rgba(15, 0, 0, 0.12)`) that ties into the warm undertone of the entire system.
**Key Characteristics:**
- Berkeley Mono as the sole typeface -- monospace everywhere, no sans-serif or serif voices
- Warm near-black primary (`#201d1d`) with reddish-brown undertone, not pure black
- Off-white text (`#fdfcfc`) with warm tint, not pure white
- Minimal 4px border radius throughout -- sharp, utilitarian corners
- 8px base spacing system scaling up to 96px
- Apple HIG-inspired semantic colors (blue, red, green, orange)
- Transparent warm borders using `rgba(15, 0, 0, 0.12)`
- Email input with generous 20px padding and 6px radius -- the most generous component radius
- Single button variant: dark background, light text, tight vertical padding (4px 20px)
- Underlined links as default link style, reinforcing the text-centric identity
## 2. Color Palette & Roles
### Primary
- **OpenCode Dark** (`#201d1d`): Primary background, button fills, link text. A warm near-black with subtle reddish-brown warmth -- rgb(32, 29, 29).
- **OpenCode Light** (`#fdfcfc`): Primary text on dark surfaces, button text. A barely-warm off-white that avoids clinical pure white.
- **Mid Gray** (`#9a9898`): Secondary text, muted links. A neutral warm gray that bridges dark and light.
### Secondary
- **Dark Surface** (`#302c2c`): Slightly lighter than primary dark, used for elevated surfaces and subtle differentiation.
- **Border Gray** (`#646262`): Stronger borders, outline rings on interactive elements.
- **Light Surface** (`#f1eeee`): Light mode surface, subtle background variation.
### Accent
- **Accent Blue** (`#007aff`): Primary accent, links, interactive highlights. Apple system blue.
- **Accent Blue Hover** (`#0056b3`): Darker blue for hover states.
- **Accent Blue Active** (`#004085`): Deepest blue for pressed/active states.
### Semantic
- **Danger Red** (`#ff3b30`): Error states, destructive actions. Apple system red.
- **Danger Hover** (`#d70015`): Darker red for hover on danger elements.
- **Danger Active** (`#a50011`): Deepest red for pressed danger states.
- **Success Green** (`#30d158`): Success states, positive feedback. Apple system green.
- **Warning Orange** (`#ff9f0a`): Warning states, caution signals. Apple system orange.
- **Warning Hover** (`#cc7f08`): Darker orange for hover on warning elements.
- **Warning Active** (`#995f06`): Deepest orange for pressed warning states.
### Text Scale
- **Text Muted** (`#6e6e73`): Muted labels, disabled text, placeholder content.
- **Text Secondary** (`#424245`): Secondary text on light backgrounds, captions.
### Border
- **Border Warm** (`rgba(15, 0, 0, 0.12)`): Primary border color, warm transparent black with red tint.
- **Border Tab** (`#9a9898`): Tab underline border, 2px solid bottom.
- **Border Outline** (`#646262`): 1px solid outline border for containers.
## 3. Typography Rules
### Font Family
- **Universal**: `Berkeley Mono`, with fallbacks: `IBM Plex Mono, ui-monospace, SFMono-Regular, Menlo, Monaco, Consolas, Liberation Mono, Courier New, monospace`
### Hierarchy
| Role | Size | Weight | Line Height | Notes |
|------|------|--------|-------------|-------|
| Heading 1 | 38px (2.38rem) | 700 | 1.50 | Hero headlines, page titles |
| Heading 2 | 16px (1.00rem) | 700 | 1.50 | Section titles, bold emphasis |
| Body | 16px (1.00rem) | 400 | 1.50 | Standard body text, paragraphs |
| Body Medium | 16px (1.00rem) | 500 | 1.50 | Links, button text, nav items |
| Body Tight | 16px (1.00rem) | 500 | 1.00 (tight) | Compact labels, tab items |
| Caption | 14px (0.88rem) | 400 | 2.00 (relaxed) | Footnotes, metadata, small labels |
### Principles
- **One font, one voice**: Berkeley Mono is used exclusively. There is no typographic variation between display, body, and code -- everything speaks in the same monospace register. Hierarchy is achieved through size and weight alone.
- **Weight as hierarchy**: 700 for headings, 500 for interactive/medium emphasis, 400 for body text. Three weight levels create the entire hierarchy.
- **Generous line-height**: 1.50 as the standard line-height gives text room to breathe within the monospace grid. The relaxed 2.00 line-height on captions creates clear visual separation.
- **Tight for interaction**: Interactive elements (tabs, compact labels) use 1.00 line-height for dense, clickable targets.
## 4. Component Stylings
### Buttons
**Primary (Dark Fill)**
- Background: `#201d1d` (OpenCode Dark)
- Text: `#fdfcfc` (OpenCode Light)

- Border-bottom: `2px solid #9a9898` (active tab indicator)
- Font: 16px, weight 500, line-height 1.00
- Use: Section switching, content filtering
### Navigation
- Clean horizontal layout with Berkeley Mono throughout
- Brand logotype left-aligned in monospace
- Links at 16px weight 500 with underline decoration
- Dark background matching page background
- No backdrop blur or transparency -- solid surfaces only
### Image Treatment
- Terminal/code screenshots as hero imagery
- Dark terminal aesthetic with monospace type
- Minimal borders, content speaks for itself
### Distinctive Components
**Terminal Hero**
- Full-width dark terminal window as hero element
- ASCII art / stylized logo within terminal frame
- Monospace command examples with syntax highlighting
- Reinforces the CLI-first identity of the product
**Feature List**
- Bulleted feature items with Berkeley Mono text
- Weight 500 for feature names, 400 for descriptions
- Tight vertical spacing between items
- No cards or borders -- pure text layout
**Email Capture**
- Light background input (`#f8f7f7`) contrasting dark page
- Generous 20px padding for comfortable typing
- 6px radius -- the roundest element in the system
- Newsletter/waitlist pattern
## 5. Layout Principles
### Spacing System
- Base unit: 8px
- Fine scale: 1px, 2px, 4px (sub-8px for borders and micro-adjustments)
- Standard scale: 8px, 12px, 16px, 20px, 24px
- Extended scale: 32px, 40px, 48px, 64px, 80px, 96px
- The system follows a clean 4/8px grid with consistent doubling
### Grid & Container
- Max content width: approximately 800-900px (narrow, reading-optimized)
- Single-column layout as the primary pattern
- Centered content with generous horizontal margins
- Hero section: full-width dark terminal element
- Feature sections: single-column text blocks
- Footer: multi-column link grid
### Whitespace Philosophy
- **Monospace rhythm**: The fixed-width nature of Berkeley Mono creates a natural vertical grid. Line-heights of 1.50 and 2.00 maintain consistent rhythm.
- **Narrow and focused**: Content is constrained to a narrow column, creating generous side margins that focus attention on the text.
- **Sections through spacing**: No decorative dividers. Sections are separated by generous vertical spacing (48-96px) rather than borders or background changes.
### Border Radius Scale
- Micro (4px): Default for all elements -- buttons, containers, badges
- Input (6px): Form inputs get slightly more roundness
- The entire system uses just two radius values, reinforcing the utilitarian aesthetic
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow, no border | Default state for most elements |
| Border Subtle (Level 1) | `1px solid rgba(15, 0, 0, 0.12)` | Section dividers, input borders, horizontal rules |
| Border Tab (Level 2) | `2px solid #9a9898` bottom only | Active tab indicator |
| Border Outline (Level 3) | `1px solid #646262` | Container outlines, elevated elements |
**Shadow Philosophy**: OpenCode's depth system is intentionally flat. There are no box-shadows in the extracted tokens -- zero shadow values were detected. Depth is communicated exclusively through border treatments and background color shifts. This flatness is consistent with the terminal aesthetic: terminals don't have shadows, and neither does OpenCode. The three border levels (transparent warm, tab indicator, solid outline) create sufficient visual hierarchy without any elevation illusion.
### Decorative Depth
- Background color shifts between `#201d1d` and `#302c2c` create subtle surface differentiation
- Transparent borders at 12% opacity provide barely-visible structure
- The warm reddish tint in border colors (`rgba(15, 0, 0, 0.12)`) ties borders to the overall warm dark palette
- No gradients, no blurs, no ambient effects -- pure flat terminal aesthetic
## 7. Interaction & Motion
### Hover States
- Links: color shift from default to accent blue (`#007aff`) or underline style change
- Buttons: subtle background lightening or border emphasis
- Accent blue provides a three-stage hover sequence: `#007aff` → `#0056b3` → `#004085` (default → hover → active)
- Danger red: `#ff3b30` → `#d70015` → `#a50011`
- Warning orange: `#ff9f0a` → `#cc7f08` → `#995f06`
### Focus States
- Border-based focus: increased border opacity or solid border color
- No shadow-based focus rings -- consistent with the flat, no-shadow aesthetic
- Keyboard focus likely uses outline or border color shift to accent blue
### Transitions
- Minimal transitions expected -- terminal-inspired interfaces favor instant state changes
- Color transitions: 100-150ms for subtle state feedback
- No scale, rotate, or complex transform animations
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | <640px | Single column, reduced padding, heading scales down |
| Tablet | 640-1024px | Content width expands, slight padding increase |
| Desktop | >1024px | Full content width (~800-900px centered), maximum whitespace |
### Touch Targets
- Buttons with 4px 20px padding provide adequate horizontal touch area
- Input fields with 20px padding ensure comfortable mobile typing
- Tab items at 16px with tight line-height may need mobile adaptation
### Collapsing Strategy
- Hero heading: 38px → 28px → 24px on smaller screens
- Navigation: horizontal links → hamburger/drawer on mobile
- Feature lists: maintain single-column, reduce horizontal padding
- Terminal hero: maintain full-width, reduce internal padding
- Footer columns: multi-column → stacked single column
- Section spacing: 96px → 64px → 48px on mobile
### Image Behavior
- Terminal screenshots maintain aspect ratio and border treatment
- Full-width elements scale proportionally
- Monospace type maintains readability at all sizes due to fixed-width nature
## 9. Agent Prompt Guide
### Quick Color Reference
- Page background: `#201d1d` (warm near-black)
- Primary text: `#fdfcfc` (warm off-white)
- Secondary text: `#9a9898` (warm gray)
- Muted text: `#6e6e73`
- Accent: `#007aff` (blue)
- Danger: `#ff3b30` (red)
- Success: `#30d158` (green)
- Warning: `#ff9f0a` (orange)
- Button bg: `#201d1d`, button text: `#fdfcfc`
- Border: `rgba(15, 0, 0, 0.12)` (warm transparent)
- Input bg: `#f8f7f7`, input border: `rgba(15, 0, 0, 0.12)`
### Example Component Prompts
- "Create a hero section on `#201d1d` warm dark background. Headline at 38px Berkeley Mono weight 700, line-height 1.50, color `#fdfcfc`. Subtitle at 16px weight 400, color `#9a9898`. Primary CTA button (`#201d1d` bg with `1px solid #646262` border, 4px radius, 4px 20px padding, `#fdfcfc` text at weight 500)."
- "Design a feature list: single-column on `#201d1d` background. Feature name at 16px Berkeley Mono weight 700, color `#fdfcfc`. Description at 16px weight 400, color `#9a9898`. No cards, no borders -- pure text with 16px vertical gap between items."
- "Build an email capture form: `#f8f7f7` background input, `1px solid rgba(15, 0, 0, 0.12)` border, 6px radius, 20px padding. Adjacent dark button (`#201d1d` bg, `#fdfcfc` text, 4px radius, 4px 20px padding). Berkeley Mono throughout."
- "Create navigation: sticky `#201d1d` background. 16px Berkeley Mono weight 500 for links, `#fdfcfc` text. Brand name left-aligned in monospace. Links with underline decoration. No blur, no transparency -- solid dark surface."
- "Design a footer: `#201d1d` background, multi-column link grid. Links at 16px Berkeley Mono weight 400, color `#9a9898`. Section headers at weight 700. Border-top `1px solid rgba(15, 0, 0, 0.12)` separator."
### Iteration Guide
1. Berkeley Mono is the only font -- never introduce a second typeface. Size and weight create all hierarchy.
2. Keep surfaces flat: no shadows, no gradients, no blur effects. Use borders and background shifts only.
3. The warm undertone matters: use `#201d1d` not `#000000`, use `#fdfcfc` not `#ffffff`. The reddish warmth is subtle but essential.
4. Border radius is 4px everywhere except inputs (6px). Never use rounded pills or large radii.
5. Semantic colors follow Apple HIG: `#007aff` blue, `#ff3b30` red, `#30d158` green, `#ff9f0a` orange. Each has hover and active darkened variants.
6. Three-stage interaction: default → hover (darkened) → active (deeply darkened) for all semantic colors.
7. Borders use `rgba(15, 0, 0, 0.12)` -- a warm transparent dark, not neutral gray. This ties borders to the warm palette.
8. Spacing follows an 8px grid: 8, 16, 24, 32, 40, 48, 64, 80, 96px. Use 4px for fine adjustments only.

- **Primary:** `#2A3FE5` — Token from style foundations.
- **Secondary:** `#F4B9B0` — Token from style foundations.
- **Success:** `#16A34A` — Token from style foundations.
- **Warning:** `#D97706` — Token from style foundations.
- **Danger:** `#DC2626` — Token from style foundations.
- **Surface:** `#000000` — Token from style foundations.
- **Text:** `#111827` — Token from style foundations.
- **Neutral:** `#000000` — Derived from the surface token for official format compatibility.
- Favor Primary (#2A3FE5) for CTA emphasis.
- Use Surface (#000000) for large backgrounds and cards.
- Keep body copy on Text (#111827) for legibility.
## 3. Typography
- **Scale:** desktop-first expressive scale
- **Families:** primary=Press Start 2P, display=Press Start 2P, mono=Space Mono
- **Weights:** 100, 200, 300, 400, 500, 600, 700, 800, 900
- Headings should carry the style personality; body text should optimize scanability and contrast.
## 4. Spacing & Grid
- **Spacing scale:** 8pt baseline grid
- Keep vertical rhythm consistent across sections and components.
- Align columns and modules to a predictable grid; avoid ad-hoc offsets.
## 5. Layout & Composition
- Prefer clear content blocks with consistent internal padding.
- Keep hierarchy obvious: headline → support text → primary action.
- Use whitespace to separate concerns before adding borders or shadows.
## 6. Components
- Buttons: primary action uses `#2A3FE5`; secondary actions stay neutral.
- Inputs: strong focus-visible states, clear labels, and predictable error messaging.
- Cards/sections: use consistent radii, spacing, and elevation strategy across the page.
## 7. Motion & Interaction
- Use subtle transitions that emphasize Primary (#2A3FE5) as the interaction signal.
- Default to short, purposeful transitions (150–250ms) with stable easing.
- Ensure hover, focus-visible, active, disabled, and loading states are explicit.
## 8. Voice & Brand
- Tone should reflect the visual style: concise, confident, and product-specific.
- Keep microcopy action-oriented and avoid generic filler language.
- Preserve the style identity in headlines while keeping UI labels literal and clear.
## 9. Anti-patterns
- Do not introduce off-palette colors when an existing token can solve the problem.
- Do not flatten hierarchy by using the same type size/weight for all text.
- Do not add decorative effects that reduce readability or accessibility.
- Do not mix unrelated visual metaphors in the same interface.

# Design System Inspired by Pinterest
> Category: Media & Consumer
> Visual discovery. Red accent, masonry grid, image-first.
## 1. Visual Theme & Atmosphere
Pinterest's website is a warm, inspiration-driven canvas that treats visual discovery like a lifestyle magazine. The design operates on a soft, slightly warm white background with Pinterest Red (`#e60023`) as the singular, bold brand accent. Unlike the cool blues of most tech platforms, Pinterest's neutral scale has a distinctly warm undertone — grays lean toward olive/sand (`#91918c`, `#62625b`, `#e5e5e0`) rather than cool steel, creating a cozy, craft-like atmosphere that invites browsing.
The typography uses Pin Sans — a custom proprietary font with a broad fallback stack including Japanese fonts, reflecting Pinterest's global reach. At display scale (70px, weight 600), Pin Sans creates large, inviting headlines. At smaller sizes, the system is compact: buttons at 12px, captions at 12–14px. The CSS variable naming system (`--comp-*`, `--sema-*`, `--base-*`) reveals a sophisticated three-tier design token architecture: component-level, semantic-level, and base-level tokens.
What distinguishes Pinterest is its generous border-radius system (12px–40px, plus 50% for circles) and warm-tinted button backgrounds. The secondary button (`#e5e5e0`) has a distinctly warm, sand-like tone rather than cold gray. The primary red button uses 16px radius — rounded but not pill-shaped. Combined with warm badge backgrounds (`hsla(60,20%,98%,.5)` — a subtle yellow-warm wash) and photography-dominant layouts, the result is a design that feels handcrafted and personal, not corporate and sterile.
**Key Characteristics:**
- Warm white canvas with olive/sand-toned neutrals — cozy, not clinical
- Pinterest Red (`#e60023`) as singular bold accent — never subtle, always confident
- Pin Sans custom font with global fallback stack (including CJK)
- Three-tier token architecture: `--comp-*` / `--sema-*` / `--base-*`
- Warm secondary surfaces: sand gray (`#e5e5e0`), warm badge (`hsla(60,20%,98%,.5)`)
- Generous border-radius: 16px standard, up to 40px for large containers
- Photography-first content — pins/images are the primary visual element
- Dark near-purple text (`#211922`) — warm, with a hint of plum
## 2. Color Palette & Roles
### Primary Brand
- **Pinterest Red** (`#e60023`): Primary CTA, brand accent — bold, confident red
- **Green 700** (`#103c25`): `--base-color-green-700`, success/nature accent
- **Green 700 Hover** (`#0b2819`): `--base-color-hover-green-700`, pressed green
### Text
- **Plum Black** (`#211922`): Primary text — warm near-black with plum undertone
- **Black** (`#000000`): Secondary text, button text
- **Olive Gray** (`#62625b`): Secondary descriptions, muted text
- **Warm Silver** (`#91918c`): `--comp-button-color-text-transparent-disabled`, disabled text, input borders
- **White** (`#ffffff`): Text on dark/colored surfaces
### Interactive
- **Focus Blue** (`#435ee5`): `--comp-button-color-border-focus-outer-transparent`, focus rings
- **Performance Purple** (`#6845ab`): `--sema-color-hover-icon-performance-plus`, performance features
- **Recommendation Purple** (`#7e238b`): `--sema-color-hover-text-recommendation`, AI recommendation
- **Link Blue** (`#2b48d4`): Link text color
- **Facebook Blue** (`#0866ff`): `--facebook-background-color`, social login
- **Pressed Blue** (`#617bff`): `--base-color-pressed-blue-200`, pressed state
### Surface & Border
- **Sand Gray** (`#e5e5e0`): Secondary button background — warm, craft-like
- **Warm Light** (`#e0e0d9`): Circular button backgrounds, badges
- **Warm Wash** (`hsla(60, 20%, 98%, 0.5)`): `--comp-badge-color-background-wash-light`, subtle warm badge bg
- **Fog** (`#f6f6f3`): Light surface (at 50% opacity)
- **Border Disabled** (`#c8c8c1`): `--sema-color-border-disabled`, disabled borders
- **Hover Gray** (`#bcbcb3`): `--base-color-hover-grayscale-150`, hover border
- **Dark Surface** (`#33332e`): Dark section backgrounds
### Semantic
- **Error Red** (`#9e0a0a`): Checkbox/form error states
## 3. Typography Rules
### Font Family
- **Primary**: `Pin Sans`, fallbacks: `-apple-system, system-ui, Segoe UI, Roboto, Oxygen-Sans, Apple Color Emoji, Segoe UI Emoji, Segoe UI Symbol, Ubuntu, Cantarell, Fira Sans, Droid Sans, Helvetica Neue, Helvetica, ヒラギノ角ゴ Pro W3, メイリオ, Meiryo, ＭＳ Ｐゴシック, Arial`
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display Hero | Pin Sans | 70px (4.38rem) | 600 | normal | normal | Maximum impact |
| Section Heading | Pin Sans | 28px (1.75rem) | 700 | normal | -1.2px | Negative tracking |
| Body | Pin Sans | 16px (1.00rem) | 400 | 1.40 | normal | Standard reading |
| Caption Bold | Pin Sans | 14px (0.88rem) | 700 | normal | normal | Strong metadata |
| Caption | Pin Sans | 12px (0.75rem) | 400–500 | 1.50 | normal | Small text, tags |
| Button | Pin Sans | 12px (0.75rem) | 400 | normal | normal | Button labels |
### Principles
- **Compact type scale**: The range is 12px–70px with a dramatic jump — most functional text is 12–16px, creating a dense, app-like information hierarchy.
- **Warm weight distribution**: 600–700 for headings, 400–500 for body. No ultra-light weights — the type always feels substantial.
- **Negative tracking on headings**: -1.2px on 28px headings creates cozy, intimate section titles.
- **Single font family**: Pin Sans handles everything — no secondary display or monospace font detected.
## 4. Component Stylings
### Buttons
**Primary Red**
- Background: `#e60023` (Pinterest Red)
- Text: `#000000` (black — unusual choice for contrast on red)
- Padding: 6px 14px
- Radius: 16px (generously rounded, not pill)
- Border: `2px solid rgba(255, 255, 255, 0)` (transparent)
- Focus: semantic border + outline via CSS variables
**Secondary Sand**
- Background: `#e5e5e0` (warm sand gray)
- Text: `#000000`
- Padding: 6px 14px
- Radius: 16px
- Focus: same semantic border system
**Circular Action**
- Background: `#e0e0d9` (warm light)
- Text: `#211922` (plum black)
- Radius: 50% (circle)
- Use: Pin actions, navigation controls
**Ghost / Transparent**
- Background: transparent
- Text: `#000000`
- No border
- Use: Tertiary actions
### Cards & Containers
- Photography-first pin cards with generous radius (12px–20px)
- No traditional box-shadow on most cards
- White or warm fog backgrounds
- 8px white thick border on some image containers
### Inputs
- Email input: white background, `1px solid #91918c` border, 16px radius, 11px 15px padding
- Focus: semantic border + outline system via CSS variables
### Navigation
- Clean header on white or warm background
- Pinterest logo + search bar centered
- Pin Sans 16px for nav links
- Pinterest Red accents for active states
### Image Treatment
- Pin-style masonry grid (signature Pinterest layout)
- Rounded corners: 12px–20px on images
- Photography as primary content — every pin is an image
- Thick white borders (8px) on featured image containers
## 5. Layout Principles
### Spacing System
- Base unit: 8px
- Scale: 4px, 6px, 7px, 8px, 10px, 11px, 12px, 16px, 18px, 20px, 22px, 24px, 32px, 80px, 100px
- Large jumps: 32px → 80px → 100px for section spacing
### Grid & Container
- Masonry grid for pin content (signature layout)
- Centered content sections with generous max-width
- Full-width dark footer
- Search bar as primary navigation element
### Whitespace Philosophy
- **Inspiration density**: The masonry grid packs pins tightly — the content density IS the value proposition. Whitespace exists between sections, not within the grid.
- **Breathing above, density below**: Hero/feature sections get generous padding; the pin grid is compact and immersive.
### Border Radius Scale
- Standard (12px): Small cards, links
- Button (16px): Buttons, inputs, medium cards
- Comfortable (20px): Feature cards
- Large (28px): Large containers
- Section (32px): Tab elements, large panels
- Hero (40px): Hero containers, large feature blocks
- Circle (50%): Action buttons, tab indicators
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Default — pins rely on content, not shadow |
| Subtle (Level 1) | Minimal shadow (from tokens) | Elevated overlays, dropdowns |
| Focus (Accessibility) | `--sema-color-border-focus-outer-default` ring | Focus states |
**Shadow Philosophy**: Pinterest uses minimal shadows. The masonry grid relies on content (photography) to create visual interest rather than elevation effects. Depth comes from the warmth of surface colors and the generous rounding of containers.
## 7. Do's and Don'ts
### Do
- Use warm neutrals (`#e5e5e0`, `#e0e0d9`, `#91918c`) — the warm olive/sand tone is the identity
- Apply Pinterest Red (`#e60023`) only for primary CTAs — it's bold and singular
- Use Pin Sans exclusively — one font for everything
- Apply generous border-radius: 16px for buttons/inputs, 20px+ for cards
- Keep the masonry grid dense — content density is the value
- Use warm badge backgrounds (`hsla(60,20%,98%,.5)`) for subtle warm washes
- Use `#211922` (plum black) for primary text — it's warmer than pure black
### Don't
- Don't use cool gray neutrals — always warm/olive-toned
- Don't use pure black (`#000000`) as primary text — use plum black (`#211922`)
- Don't use pill-shaped buttons — 16px radius is rounded but not pill
- Don't add heavy shadows — Pinterest is flat by design, depth from content
- Don't use small border-radius (<12px) on cards — the generous rounding is core
- Don't introduce additional brand colors — red + warm neutrals is the complete palette
- Don't use thin font weights — Pin Sans at 400 minimum
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | <576px | Single column, compact layout |
| Mobile Large | 576–768px | 2-column pin grid |
| Tablet | 768–890px | Expanded grid |
| Desktop Small | 890–1312px | Standard masonry grid |
| Desktop | 1312–1440px | Full layout |
| Large Desktop | 1440–1680px | Expanded grid columns |
| Ultra-wide | >1680px | Maximum grid density |
### Collapsing Strategy
- Pin grid: 5+ columns → 3 → 2 → 1
- Navigation: search bar + icons → simplified mobile nav
- Feature sections: side-by-side → stacked
- Hero: 70px → scales down proportionally
- Footer: dark multi-column → stacked
## 9. Agent Prompt Guide
### Quick Color Reference
- Brand: Pinterest Red (`#e60023`)
- Background: White (`#ffffff`)
- Text: Plum Black (`#211922`)
- Secondary text: Olive Gray (`#62625b`)
- Button surface: Sand Gray (`#e5e5e0`)
- Border: Warm Silver (`#91918c`)
- Focus: Focus Blue (`#435ee5`)
### Example Component Prompts
- "Create a hero: white background. Headline at 70px Pin Sans weight 600, plum black (#211922). Red CTA button (#e60023, 16px radius, 6px 14px padding). Secondary sand button (#e5e5e0, 16px radius)."
- "Design a pin card: white background, 16px radius, no shadow. Photography fills top, 16px Pin Sans weight 400 description below in #62625b."
- "Build a circular action button: #e0e0d9 background, 50% radius, #211922 icon."
- "Create an input field: white background, 1px solid #91918c, 16px radius, 11px 15px padding. Focus: blue outline via semantic tokens."
- "Design the dark footer: #33332e background. Pinterest script logo in white. 12px Pin Sans links in #91918c."
### Iteration Guide
1. Warm neutrals everywhere — olive/sand grays, never cool steel
2. Pinterest Red for CTAs only — bold and singular
3. 16px radius on buttons/inputs, 20px+ on cards — generous but not pill
4. Pin Sans is the only font — compact at 12px for UI, 70px for display
5. Photography carries the design — the UI stays warm and minimal
6. Plum black (#211922) for text — warmer than pure black

# Design System Inspired by PlayStation
> Category: Media & Consumer
> Gaming console retail. Three-surface channel layout, quiet-authority display type, cyan hover-scale.
## 1. Visual Theme & Atmosphere
PlayStation.com carries itself like the marketing wing of a premium consumer-electronics brand that happens to sell entertainment. The page is organized as a **vertical channel of alternating surfaces**: a near-black masthead and hero, a sequence of paper-white editorial panels in the middle, and a deep cobalt-blue footer that anchors the entire experience. Between those surface modes the site leans hard on photography and 3D product renders — the PS5 console, game cover art, DualSense controllers — letting the hardware do the emotional work while the chrome stays restrained.
The signature typographic move is **SST Light (weight 300) at large sizes**. Sony's custom SST family is used from 22px up to 54px in weight 300, giving display headlines a whispered, elegant quality that feels closer to a luxury watch ad than a game store. That "quiet authority" is the exact opposite of The Verge's Manuka shout or Wired's newsstand density — PlayStation wants the type to recede and the product to lead. Body and UI lean on weights 500–700, but the *display* voice is consistently thin and calm.
The one place restraint breaks is **interaction**. Every primary button has the same hover move: fill swaps to an electric cyan `#1eaedb`, a 2px white border appears, a 2px PlayStation-blue outer ring blooms behind it, and the entire button **scales up 1.2×**. That combination of color pop, border, ring, and lift-scale is a signature move unique to Sony among major brands — a miniature "power-on" animation that the site repeats hundreds of times across a single page.
**Key Characteristics:**
- Three-surface channel layout: near-black hero, paper-white content, cobalt-blue footer — alternating, never blending
- SST weight 300 at 22–54px for display — "quiet authority" headlines that let product photography lead
- PlayStation Blue `#0070cc` as the brand anchor; cyan `#1eaedb` reserved exclusively for hover/focus states
- Every interactive element scales 1.2× on hover — a signature "power-on" lift unique to PlayStation
- Pill buttons at full 999px radius; card art in rounded 12–24px rectangles
- Commerce-orange `#d53b00` used exclusively for PlayStation Store / buy-state CTAs
- Wide breakpoint coverage up to 2120px — the site scales all the way to 4K-TV browsing contexts
## 2. Color Palette & Roles
### Primary (Brand Anchor)
- **PlayStation Blue** (`#0070cc`): The brand's anchor color. Used on the primary footer, inline links, primary button fills on dark surfaces, and every "official" marker. Treat this as immovable — it is the color the brand is most associated with in consumer memory.
- **Console Black** (`#000000`): Pure black for the masthead, hero backdrops, and product presentation zones. PlayStation uses black to frame hardware the way a museum uses black to frame a sculpture.
### Secondary & Accent
- **PlayStation Cyan** (`#1eaedb`): The interaction color. Applied ONLY to hover, focus, and active states of buttons and links. Never appears as a default background or a text color at rest. Pair with a 2px `#ffffff` border and a 2px `#0070cc` outer ring on hover for the full signature treatment.
- **Link Hover Blue** (`#1883fd`): The brighter variant used on inline text-link hovers. Distinct from Cyan — this is the link color, Cyan is the button color.
- **Dark Link Blue** (`#0068bd`): The link color at rest on light surfaces — a slightly more saturated cousin of the brand blue.
### Surface & Background
- **Paper White** (`#ffffff`): Primary content canvas for editorial panels between the masthead and footer.
- **Ice Mist** (`#f5f7fa`): The atmospheric end-stop of the light section-gradient. Used subtly behind certain panels to lift them off pure white.
- **Divider Tint** (`#f3f3f3`): The quiet horizontal-rule color between content rows.
- **Masthead Black** (`#000000`): Top nav and hero canvas — reserved for product-forward zones.
- **Shadow Black** (`#121314`): The starting anchor of the dark section-gradient when a panel needs atmospheric depth.
- **Filter Mist** (`rgba(245, 247, 250, 0.3)`): Translucent background used behind sticky filter bars — the only "glassmorphism" moment on the site.
### Neutrals & Text
- **Display Ink** (`#000000`): Primary display headlines on white surfaces.
- **Deep Charcoal** (`#1f1f1f`): Body headlines and link color at rest — slightly softer than pure black to reduce visual ring on large blocks.
- **Body Gray** (`#6b6b6b`): Secondary body text and metadata.
- **Mute Gray** (`#cccccc`): Tertiary labels, disabled states.
- **Placeholder Ink** (`rgba(0, 0, 0, 0.6)`): Form placeholder text — 60% black, not a separate gray value.
- **Inverse White** (`#ffffff`): Primary text on dark and blue surfaces.
- **Dark-Link Blue** (`#53b1ff`): The link color at rest on dark/black surfaces — a lighter airborne variant of PlayStation Blue for legibility on black.
### Semantic & Commerce
- **Commerce Orange** (`#d53b00`): Reserved for PlayStation Store buy-state CTAs, price callouts, and "on sale" badges. The only warm color on the site — use sparingly and never outside a commerce context.
- **Commerce Orange Active** (`#aa2f00`): The pressed/active state of commerce buttons.
- **Warning Red** (`#c81b3a`): Form errors and destructive-action warnings.
- **Shadow Wash 80** (`rgba(0, 0, 0, 0.8)`): The dramatic scrim used behind hero text on product photography.
- **Shadow Wash 16** (`rgba(0, 0, 0, 0.16)`): Low-weight elevation ring on cards.
- **Shadow Wash 08** (`rgba(0, 0, 0, 0.08)`): Featherweight card elevation — barely visible but separates white panels from white background.
- **Shadow Wash 06** (`rgba(0, 0, 0, 0.06)`): The lightest shadow in the system.
### Gradient System
PlayStation uses **two section gradients** and nothing else:
- **Light Section Gradient**: from `#ffffff` → `#f5f7fa` — an almost-imperceptible wash that quietly lifts a panel off the canvas.
- **Dark Section Gradient**: from `#121314` → `#000000` — a short vertical wash that gives hero panels a subtle vignette without introducing any hue shift.
Both gradients are used **only as section backgrounds**, never inside components. There are no gradient buttons, no gradient text, no glowing halos. The brand is blue — not blue-to-purple, not blue-to-cyan.
## 3. Typography Rules
### Font Family
- **SST** / **Playstation SST** (Sony, proprietary) — fallback: `Arial`, `Helvetica`. Sony's custom global typeface, designed by Toshi Omagari and Akira Kobayashi. Covers weights 300 / 500 / 600 / 700 across the homepage. The weight **300 at 22–54px** is PlayStation's typographic signature.
- **SST (condensed / alternate)** — fallback: `helvetica`, `arial`. A compressed variant used in a handful of UI modules where width matters.
- **Arial** — utility fallback for the rare button variant that renders in system sans.
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|---|---|---|---|---|---|---|
| Hero Display (XL) | SST | 54px / 3.38rem | 300 | 1.25 | -0.1px | The biggest SST moment on the page — quiet-weight luxury headline |
| Hero Display (L) | SST | 44px / 2.75rem | 300 | 1.25 | 0.1px | Secondary hero headlines |
| Large Display | SST | 35px / 2.20rem | 300 | 1.25 | — | Feature panel headlines |
| Mid Display | SST | 28px / 1.75rem | 300 | 1.25 | 0.1px | Section headings |
| Compact Display | SST | 22px / 1.38rem | 300 | 1.25 | 0.1px | Module titles — still in light weight 300 |
| Playstation SST Sub | Playstation SST | 22.5px / 1.41rem | 400 | 1.30 | — | Promotional sub-heading |
| UI Heading Small | SST | 18px / 1.13rem | 600 | 1.00 | — | Tight UI headings |
| Button / CTA | SST | 18px / 1.13rem | 500 | 1.25 | 0.4px | Primary button label |
| Button / Emphasized | SST | 18px / 1.13rem | 700 | 1.25 | 0.45px | Higher-emphasis CTAs (buy, subscribe) |
| Button Serif | SST | 18px / 1.13rem | 600 | 1.50 | — | Secondary button label |
| Body Relaxed | SST | 18px / 1.13rem | 400 | 1.50 | 0.1px | Standard reading body |
| Link Body | SST | 18px / 1.13rem | 400 | 1.50 | — | Inline link text |
| Compact Button | SST | 14px / 0.88rem | 700 | 1.25 | 0.324px | Mini CTAs in cards |
| Utility Caption | SST | 14px / 0.88rem | 500 | 1.50 | — | Captions, tag labels |
| Caption Body | SST | 14px / 0.88rem | 400 | 1.50 | — | Standard metadata |
| Playstation Caption Bold | Playstation SST | 14px / 0.88rem | 700 | 1.40 | — | Emphasized caption |
| Playstation Caption Mid | Playstation SST | 14px / 0.88rem | 600 | 1.40 | — | Semi-bold caption |
| Playstation Button | Playstation SST | 14.4px / 0.90rem | 700 | 1.00 | 0.144px | UI button with tight leading |
| Playstation Tab | Playstation SST | 14px / 0.88rem | 400 | 1.10 | 0.14px | Tab/pill label |
| Playstation Compact Caption | Playstation SST | 12.8px / 0.80rem | 400 | 1.10 | — | Smallest UI caption |
| Micro Caption | SST | 12px / 0.75rem | 500 | 1.50 | — | Footer microcopy, legal text |
| Compact Caption Bold | SST | 12.06px / 0.75rem | 700 | 1.50 | — | Emphasized micro text |
### Principles
- **Weight 300 at large sizes is the voice.** PlayStation is the only major console brand that uses a light-weight display for its hero headlines. Resist the urge to "upgrade" display type to 500 or 700 — the quietness is the personality.
- **Weight jumps at the UI layer.** Below 18px the system shifts to 500–700 for legibility. The weight gradient from 300 (display) → 400 (body) → 500 (captions) → 700 (buttons) is the hierarchy.
- **Letter-spacing is barely-there.** Most values are 0.1–0.45px, either positive or slightly negative. The `-0.1px` on the 54px hero tightens the display type just enough to read as "designed" without becoming a typographic statement.
- **Two SST casings.** "SST" and "Playstation SST" are functionally the same family with slightly different metric sets (Playstation SST is tighter at small sizes). Treat them as interchangeable for purposes outside Sony's internal licensing.
- **No all-caps.** Unlike The Verge or Wired, PlayStation rarely uses UPPERCASE labels. Kickers and tags stay in title case or sentence case — another "quiet authority" move.
- **No serif anywhere.** The entire system is sans. There is no print-voice counterpoint.
## 4. Component Stylings
### Buttons
**Primary — PlayStation Blue Pill**
- Background: `#0070cc` (PlayStation Blue)
- Text: `#ffffff`, SST 18px / 500 / 0.4px tracking
- Border: none at rest
- Border radius: `999px` — full pill
- Padding: ~`12px 24px` (variable based on size class)
- Outline: `rgb(255, 255, 255) none 0px` at rest
- **Hover (signature move)**:
- Background fills to `#1eaedb` (PlayStation Cyan)
- Text stays `#ffffff`
- 2px `#ffffff` border appears
- 2px `#0070cc` outer ring shadow blooms (`0 0 0 2px #0070cc`)
- `transform: scale(1.2)` — the button actually grows 20%
- Active: `opacity: 0.6` — a quick dim to signal press
- Focus: Same as hover, but the ring turns into `rgb(0, 114, 206) 0px 0px 0px 2px` focus shadow
- Transition: ~180ms ease on background, transform, and shadow
**Secondary — White Outline on Dark**
- Background: `#ffffff`
- Text: `#0172ce` (PlayStation Blue variant)
- Border: `2px outset #000000` — a genuine `outset` border, which is extremely rare in modern CSS
- Radius: varies (often `999px` or `36px`)
- Padding: `16px 20px`
- Hover: same signature cyan fill + scale(1.2) + ring treatment
- Focus: same ring treatment
**Commerce Orange**
- Background: `#d53b00` (Commerce Orange)
- Text: `#ffffff`, SST 18px / 700 / 0.45px tracking
- Border radius: `999px` — pill
- Used only on PS Store / Buy / Subscribe Plus CTAs
- Active: background darkens to `#aa2f00`
- Hover: follows the cyan-invert rule like all other buttons (NOT an orange-specific hover)
**Transparent Ghost**
- Background: transparent
- Text: `#1f1f1f` (Deep Charcoal)
- Border: `1px solid #dedede`
- Padding: `0 10px` (tight, nav-optimized)
- Hover: cyan fill, white text, 2px white border, scale(1.2)
- Active: text shifts to `#0072ce`, opacity 0.6
**Icon Circle**
- Background: `rgba(0, 0, 0, 0.2)` on photography; `#ffffff` on light surfaces
- Border radius: `100%` — perfect circle
- Used for carousel prev/next arrows and share buttons
- Hover: lightens to `var(--color-role-backgrounds-primary-link-hover)` (roughly `#e5e5e5` on light)
**Mini CTA (In-card)**
- SST 14px / 700 / 0.324px tracking
- Padding ~8px 16px
- Radius: `999px`
- Used inside game cards for "Buy Now" / "Add to Cart" mini CTAs
### Cards & Containers
**Hero Card (Game Feature)**
- Background: photography/render — usually black-anchored
- Border radius: `24px` or `19px` for feature cards
- Padding: 32–48px interior
- Shadow: `rgba(0, 0, 0, 0.8) 0px 5px 9px 0px` — a dramatic drop-shadow only used when a card overlaps the hero photography
- Hover: subtle scale transform, cyan outline appears on primary CTA
**Game Cover Tile**
- Background: game cover art, unpadded
- Border radius: `12px` or `13px` (images) / `19px` (card frame)
- Shadow: `rgba(0, 0, 0, 0.08) 0px 5px 9px 0px` — feather-weight elevation
- Hover: the card's primary CTA lights up cyan, the card itself may scale 1.02×
- Transition: 200ms ease on transform
**Content Panel (White)**
- Background: `#ffffff` or the light section gradient `#ffffff → #f5f7fa`
- Border: typically none; separated from neighbors by spacing and subtle shadows
- Radius: `12px`–`24px` depending on panel hierarchy
- Shadow: `rgba(0, 0, 0, 0.06) 0px 5px 9px 0px` — the lightest in the system
**Dark Card on Dark**
- Background: `rgba(0, 0, 0, 0.2)` over photography
- Border radius: `6px` (compact) or `24px` (feature)
- Used for "press kit" or "stat block" inlays over hero video
### Inputs & Forms
- **Default**: `#ffffff` background, `1px solid #cccccc` border, `3px` border radius (tighter than the rest of the system — inputs are the one place where PlayStation gets genuinely compact), SST 16px text in `#1f1f1f`, placeholder `rgba(0, 0, 0, 0.6)`.
- **Focus**: 2px `#0070cc` focus ring via `box-shadow: 0 0 0 2px #0070cc`. No border-color change — the ring does the work.
- **Error**: border and text shift to `#c81b3a` (Warning Red), inline error text below in the same red.
- **Transition**: ~180ms ease on border and shadow.
### Navigation
- **Top nav**: black (`#000000`) full-bleed strip with the PlayStation logo (white) left-aligned, category links centered in SST 14–16px / 500, and a small "Sign In" CTA right-aligned.
- **Hover on nav link**: color transitions from `#ffffff` to `#1883fd` (Link Hover Blue), no underline.
- **Active section**: marked by a subtle 2px underline in `#0070cc`.
- **Mobile**: nav collapses to a hamburger drawer. Inside the drawer, links stack vertically with 16px gaps and 20px horizontal padding.
- **Sticky behavior**: the nav stays pinned at the top on scroll; when it enters a light-surface zone it **does not invert** — it stays black-backed throughout.
### Image Treatment
- **Aspect ratios**: 16:9 hero video/photography, 1:1 console renders, 3:4 game cover art, 4:3 lifestyle imagery.
- **Corners**: rounded to `12px`, `13px`, or `24px` depending on card context. Game covers get `6–12px`, hero images get `24px`.
- **Full-bleed**: only in the masthead hero and footer promotional banners. Everything else sits inside a padded content column.
- **Shadow**: dramatic `rgba(0, 0, 0, 0.8) 0 5px 9px 0` drop on heroes, feather `rgba(0, 0, 0, 0.06) 0 5px 9px 0` on grid tiles.
- **Hover**: image stays static, the card frame and primary CTA respond.
- **Lazy loading**: `loading="lazy"` on everything below the fold, `eager` on the masthead hero.
### Game Store Pill (Distinctive)
- Background: `#ffffff`
- Text: `#000000`, SST 14px / 500
- Padding: `14px 18px`
- Radius: `9999px` — full pill
- A neutral pill tag that sits next to game covers to label platform ("PS5", "PS4", "PSVR2"). White-on-dark contrast.
## 5. Layout Principles
### Spacing System
- **Base unit**: 8px.
- **Scale**: 1, 2, 3, 4.5, 5, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21px.
- **Section padding**: 48–96px vertical between major panels. Hero-to-content transitions use the larger end.
- **Card padding**: 20–32px interior. Feature hero cards can expand to 48px.
- **Inline spacing**: 8–12px between headline and deck, 12–16px between deck and CTA.
- **Micro-scale**: The 1/2/3/4.5/5/9/10/12 values are used for pill padding, caption spacing, and border offsets — not for editorial rhythm.
### Grid & Container
- **Max width**: ~1920px (dembrandt detected breakpoints up to 2120px). Container caps typically around `1280–1920px` depending on panel.
- **Column patterns**: 12-column responsive grid that resolves into 3/4/6-column game tile rows depending on hierarchy. Hero zones often span 12 columns; featured tiles sit in 6+3+3 or 4+4+4 configurations.
- **Outer padding**: 16px mobile → 48px tablet → 64–96px desktop.
- **Gutters**: 16–24px between columns, tighter (8–12px) inside tile clusters.
### Whitespace Philosophy
PlayStation treats whitespace like a luxury brand treats store lighting — as a premium signal. There is noticeably more vertical breathing room between modules than on any other major retail site, and the white editorial panels often hold only one headline + one image + one CTA at hero-scale padding. The effect is a "gallery pace" where each product gets its own room rather than competing in a grid of thumbnails.
### Border Radius Scale
- **2px** — cookie banner buttons and small admin UI
- **3px** — form inputs, tab panels (tighter than everything else — a deliberate "functional UI" cue)
- **6px** — compact buttons and inline images
- **12px** — standard game cover images and content images
- **13px** — certain figure wrappers (a 1px offset from 12px for nesting)
- **19px** — feature cards
- **20px** — inline tag spans
- **24px** — hero cards, primary feature frames
- **36px** — full-pill nav and secondary button variants
- **48px** — large feature buttons
- **999px / 100%** — full pill primary buttons and circular icon buttons
Eleven discrete radius values — one of the richest radius systems of any site in this catalog. The range exists because PlayStation deliberately uses different radii for different *hierarchies*: 3px for utility, 12px for media, 24px for features, 999px for CTAs.
## 6. Depth & Elevation
| Level | Treatment | Use |
|---|---|---|
| 0 | No shadow | Default content on `#ffffff` |
| 1 | `rgba(0, 0, 0, 0.06) 0 5px 9px 0` | Feather-light editorial panel lift |
| 2 | `rgba(0, 0, 0, 0.08) 0 5px 9px 0` | Standard grid tile elevation |
| 3 | `rgba(0, 0, 0, 0.16) 0 5px 9px 0` | Emphasized card (hover or active) |
| 4 | `rgba(0, 0, 0, 0.8) 0 5px 9px 0` | Hero overlay shadow — dramatic drop used over photography |
| 5 | `0 0 0 2px #0070cc` (focus ring) | Primary button focus state |
| 6 | `0 0 0 2px #000000` (hover ring) | Secondary button hover ring |
| 7 | Section gradient `#121314 → #000000` | Atmospheric depth on dark hero panels |
PlayStation's depth philosophy is **layered but restrained**. The shadow scale runs from 0.06 to 0.16 for normal states, then jumps to 0.8 for hero drops — there is no 0.2, 0.3, 0.4 middle ground. The effect is that most of the page sits almost flat, but when a hero card needs to float over photography, it genuinely *floats*. Elevation is either whispered or shouted, never muttered.
### Decorative Depth
- **Section gradients** (dark and light, both described above) — used only as section backgrounds
- **Focus/hover rings** at 2px, always blue or cyan depending on state
- **No glows, blurs, or atmospheric effects** beyond the two section gradients
- **No gradient buttons or text** — the visual system is solid color blocks everywhere except section transitions
## 7. Do's and Don'ts
### Do
- **Do** use PlayStation Blue (`#0070cc`) as the primary CTA fill and the footer anchor. It is the brand's anchor color.
- **Do** use SST weight 300 for every display headline 22px and above. The quiet-weight headline is the voice.
- **Do** apply the full hover signature to every primary button: cyan fill + 2px white border + 2px blue outer ring + `scale(1.2)`.
- **Do** use full-pill radius (`999px`) on primary and commerce buttons.
- **Do** reserve PlayStation Cyan (`#1eaedb`) exclusively for hover, focus, and active states — never as a resting background.
- **Do** use Commerce Orange (`#d53b00`) only on PlayStation Store / purchase CTAs and price callouts.
- **Do** alternate dark hero panels with white content panels and anchor with a deep blue footer — the three-surface channel layout is the page rhythm.
- **Do** use dramatic `rgba(0, 0, 0, 0.8)` hero drop shadows when a card overlaps product photography.
- **Do** keep the top nav black on every scroll position — it does not invert to white over light panels.
### Don't
- **Don't** bold display headlines. Weight 300 at 22–54px is the PlayStation voice. Weight 700 display type reads as "another game retailer".
- **Don't** use ALL-CAPS labels or kickers. PlayStation rarely uses uppercase — it is a quiet-authority brand, not a hazard-tape one.
- **Don't** use gradient buttons, text, or backgrounds outside the two declared section gradients.
- **Don't** introduce warm colors outside Commerce Orange. No red CTAs, no yellow highlights, no green success pills.
- **Don't** use square corners on buttons or media. The system has eleven radii — pick one, but never `0`.
- **Don't** skip the `scale(1.2)` hover move on primary buttons. The lift-scale is a brand interaction signature.
- **Don't** use serif type. The system is 100% SST sans.
- **Don't** let cyan `#1eaedb` appear as a text or background color at rest. It only exists in motion.
- **Don't** design panels that fight for attention. PlayStation's whitespace rhythm gives each module its own "gallery room".
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|---|---|---|
| Small Mobile | <400px | Single column, nav collapses to hamburger, SST hero scales to ~28px |
| Mobile | 400–599px | Single column, tiles stack full-width, padding opens to 16px |
| Large Mobile | 600–767px | Still single column but 2-column tile option in select modules |
| Tablet Portrait | 768–1023px | 2-column game grid, nav still condensed |
| Tablet Landscape | 1024–1279px | 3–4 column grid, full nav restored |
| Desktop | 1280–1599px | Full editorial grid, max hero display scale (44–54px) |
| Large Desktop | 1600–1919px | Container caps at 1600px, margins expand |
| 4K / Big-Screen | ≥1920px | Container expands to 1920px max, hero content scales up to match TV viewing distance |
| Ultra-Wide | ≥2120px | Extreme breakpoint — page stays anchored, outer margins absorb extra width |
The dembrandt sweep detected 30 breakpoints between 320px and 2120px — an unusually wide responsive range. PlayStation tunes specifically for **big-screen contexts** (1920–2120px) because PS5 owners frequently browse the site on TVs via the console's browser or via cast-to-TV from a phone. Most retail sites stop tuning at 1440px; PlayStation keeps tuning through 4K.
### Touch Targets
- Primary pill buttons are ~48–56px tall (SST 18px text + ~12–16px vertical padding) — comfortably WCAG AAA.
- Nav links are smaller (~32–40px tall) at desktop; on mobile they pad out to 48px+ inside the drawer.
- Icon circle buttons are 40–48px — touch-friendly.
### Collapsing Strategy
- **Nav**: full nav → condensed → hamburger drawer as viewport narrows. Logo stays pinned left; CTA stays pinned right.
- **Grid**: 6-col → 4-col → 3-col → 2-col → 1-col. Game tile cards reflow without cropping cover art.
- **Spacing**: section padding tightens from 96px → 64px → 48px → 32px → 24px as viewport narrows.
- **Type**: SST hero scales from 54px → 44px → 35px → 28px → 22px. The light weight 300 is preserved at every size.
- **Hero photography**: art-direction swap — desktop uses wide 16:9 crops, mobile uses 4:3 or 1:1 crops with the product centered.
### Image Behavior
- Responsive raster (`srcset` + `<picture>` with art-direction), aspect ratios preserved per breakpoint.
- 4K-ready: the site serves high-density imagery at 1920px+ to avoid upscaling on TV browsing.
- `loading="lazy"` on everything below the fold; hero is `eager` with a preload hint.
## 9. Agent Prompt Guide
### Quick Color Reference
- **Primary CTA**: "PlayStation Blue (`#0070cc`)"
- **Hover / Focus Accent**: "PlayStation Cyan (`#1eaedb`)"
- **Background (White Surface)**: "Paper White (`#ffffff`)"
- **Background (Dark Surface)**: "Console Black (`#000000`)"
- **Heading Text on White**: "Display Ink (`#000000`)"
- **Body Text on White**: "Deep Charcoal (`#1f1f1f`)"
- **Body Text on Black**: "Inverse White (`#ffffff`)"
- **Commerce / Buy Accent**: "Commerce Orange (`#d53b00`)"
- **Footer Anchor**: "PlayStation Blue (`#0070cc`)"
### Example Component Prompts
1. *"Create a primary CTA button with a `#0070cc` PlayStation Blue fill, white text in SST 18px / 500 / 0.4px tracking, 999px border radius, 12px × 24px padding. On hover, the background transitions to `#1eaedb` PlayStation Cyan, a 2px `#ffffff` border appears, a 2px `#0070cc` outer ring blooms via box-shadow, and the entire button scales 1.2× — all in a 180ms ease transition."*
2. *"Design a hero panel on a `#000000` Console Black canvas with a 54px SST weight 300 headline in `#ffffff` with -0.1px letter-spacing and 1.25 line-height. Place a single primary CTA below with the standard PlayStation hover treatment. No ALL-CAPS labels anywhere."*
3. *"Build a game cover tile: 3:4 aspect ratio image with 12px border radius, feather-weight `rgba(0, 0, 0, 0.08) 0 5px 9px 0` drop shadow, a 14px SST 700 title below, a 12px SST 500 platform tag, and a mini 14px / 700 / 0.324px tracking primary CTA in PlayStation Blue."*
4. *"Create a commerce pill button for a PlayStation Store purchase: `#d53b00` Commerce Orange fill, `#ffffff` text in SST 18px / 700 / 0.45px tracking, 999px radius, 12px × 28px padding. Active state darkens to `#aa2f00`. Hover follows the standard cyan-invert with 1.2× scale."*
5. *"Design a white content panel between dark hero sections: `#ffffff` background with the subtle `#ffffff → #f5f7fa` light section gradient, 24px border radius, 48px interior padding, feather-weight `rgba(0, 0, 0, 0.06) 0 5px 9px 0` elevation, a 35px SST 300 headline, a 18px body paragraph, and a single primary CTA."*
### Iteration Guide
When refining existing screens generated with this design system:
1. **Audit display weight.** Every headline 22px and above should be SST weight 300. If you see weight 500 or 700 at hero scale, you've lost the PlayStation voice.
2. **Audit the hover treatment.** Every primary button must scale 1.2× on hover with the cyan-fill + white-border + blue-ring combination. Miss any of those four and the interaction signature breaks.
3. **Audit corners.** Every container and button should land on 2, 3, 6, 12, 13, 19, 20, 24, 36, 48, or 999px / 100%. Square corners break the voice.
4. **Audit color sprawl.** Only PlayStation Blue (`#0070cc`), Cyan (`#1eaedb`), Commerce Orange (`#d53b00`), and the declared grays/blacks/whites should appear in chrome. If you see any other hue, correct it.
5. **Audit surface alternation.** The page should alternate dark hero → white content → dark hero → white content → blue footer. If two same-surface panels are adjacent, insert a transition.
6. **Audit casing.** Sentence case and title case only. No ALL-CAPS labels, buttons, or kickers. If you see uppercase, convert it.
7. **Audit shadow weight.** Shadow opacity should land on 0.06 / 0.08 / 0.16 / 0.8 — nothing in between. If you see 0.1, 0.2, 0.3, 0.5 drop shadows, correct to the nearest declared tier.
8. **Audit whitespace.** If two modules feel "competitive" (fighting for attention), add 48–96px of vertical breathing room. PlayStation's gallery-pace rhythm is non-negotiable.

# Design System Inspired by PostHog
> Category: Backend & Data
> Product analytics. Playful hedgehog branding, developer-friendly dark UI.
## 1. Visual Theme & Atmosphere
PostHog's website feels like a startup's internal wiki that escaped into the wild — warm, irreverent, and deliberately anti-corporate. The background isn't the expected crisp white or dark void of developer tools; it's a warm, sage-tinted cream (`#fdfdf8`) that gives every surface a handmade, paper-like quality. Colors lean into earthy olive greens and muted sage rather than the conventional blues and purples of the SaaS world. It's as if someone designed a developer analytics platform inside a cozy garden shed.
The personality is the star: hand-drawn hedgehog illustrations, quirky action figures, and playful imagery replace the stock photography and abstract gradients typical of B2B SaaS. IBM Plex Sans Variable serves as the typographic foundation — a font with genuine technical credibility (created by IBM, widely used in developer contexts) deployed here with bold weights (700, 800) on headings and generous line-heights on body text. The typography says "we're serious engineers" while everything around it says "but we don't take ourselves too seriously."
The interaction design carries the same spirit: hover states flash PostHog Orange (`#F54E00`) text — a hidden brand color that doesn't appear at rest but surprises on interaction. Dark near-black buttons (`#1e1f23`) use opacity reduction on hover rather than color shifts, and active states scale slightly. The border system uses sage-tinted grays (`#bfc1b7`) that harmonize with the olive text palette. Built on Tailwind CSS with Radix UI and shadcn/ui primitives, the technical foundation is modern and component-driven, but the visual output is stubbornly unique.
**Key Characteristics:**
- Warm sage/olive color palette instead of conventional blues — earthy and approachable
- IBM Plex Sans Variable font at bold weights (700/800) for headings with generous 1.50+ line-heights
- Hidden brand orange (`#F54E00`) that only appears on hover interactions — a delightful surprise
- Hand-drawn hedgehog illustrations and playful imagery — deliberately anti-corporate
- Sage-tinted borders (`#bfc1b7`) and backgrounds (`#eeefe9`) creating a unified warm-green system
- Dark near-black CTAs (`#1e1f23`) with opacity-based hover states
- Content-heavy editorial layout — the site reads like a magazine, not a typical landing page
- Tailwind CSS + Radix UI + shadcn/ui component architecture
## 2. Color Palette & Roles
### Primary
- **Olive Ink** (`#4d4f46`): Primary text color — a distinctive olive-gray that gives all text a warm, earthy tone
- **Deep Olive** (`#23251d`): Link text and high-emphasis headings — near-black with green undertone
- **PostHog Orange** (`#F54E00`): Hidden brand accent — appears only on hover states, a vibrant orange that surprises
### Secondary & Accent
- **Amber Gold** (`#F7A501`): Secondary hover accent on dark buttons — warm gold that pairs with the orange
- **Gold Border** (`#b17816`): Special button borders — an amber-gold for featured CTAs
- **Focus Blue** (`#3b82f6`): Focus ring color (Tailwind default) — the only blue in the system, reserved for accessibility
### Surface & Background
- **Warm Parchment** (`#fdfdf8`): Primary page background — warm near-white with yellow-green undertone
- **Sage Cream** (`#eeefe9`): Input backgrounds, secondary surfaces — light sage tint
- **Light Sage** (`#e5e7e0`): Button backgrounds, tertiary surfaces — muted sage-green
- **Warm Tan** (`#d4c9b8`): Featured button backgrounds — warm tan/khaki for emphasis
- **Hover White** (`#f4f4f4`): Universal hover background state
### Neutrals & Text
- **Olive Ink** (`#4d4f46`): Primary body and UI text
- **Muted Olive** (`#65675e`): Secondary text, button labels on light backgrounds
- **Sage Placeholder** (`#9ea096`): Placeholder text, disabled states — warm sage-green
- **Sage Border** (`#bfc1b7`): Primary border color — olive-tinted gray for all borders
- **Light Border** (`#b6b7af`): Secondary border, toolbar borders — slightly darker sage
### Semantic & Accent
- **PostHog Orange** (`#F54E00`): Hover text accent — signals interactivity and brand personality
- **Amber Gold** (`#F7A501`): Dark button hover accent — warmth signal
- **Focus Blue** (`#3b82f6` at 50% opacity): Keyboard focus rings — accessibility-only color
- **Dark Text** (`#111827`): High-contrast link text — near-black for important links
### Gradient System
- No gradients on the marketing site — PostHog's visual language is deliberately flat and warm
- Depth is achieved through layered surfaces and border containment, not color transitions
## 3. Typography Rules
### Font Family
- **Display & Body**: `IBM Plex Sans Variable` — variable font (100–700+ weight range). Fallbacks: `IBM Plex Sans, -apple-system, system-ui, Avenir Next, Avenir, Segoe UI, Helvetica Neue, Helvetica, Ubuntu, Roboto, Noto, Arial`
- **Monospace**: `ui-monospace, SFMono-Regular, Menlo, Monaco, Consolas, Liberation Mono, Courier New` — system monospace stack
- **Code Display**: `Source Code Pro` — with fallbacks: `Menlo, Consolas, Monaco`
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display Hero | IBM Plex Sans Variable | 30px | 800 | 1.20 | -0.75px | Extra-bold, tight, maximum impact |
| Section Heading | IBM Plex Sans Variable | 36px | 700 | 1.50 | 0px | Large but generous line-height |
| Feature Heading | IBM Plex Sans Variable | 24px | 700 | 1.33 | 0px | Feature section titles |
| Card Heading | IBM Plex Sans Variable | 21.4px | 700 | 1.40 | -0.54px | Slightly unusual size (scaled) |
| Sub-heading | IBM Plex Sans Variable | 20px | 700 | 1.40 | -0.5px | Content sub-sections |
| Sub-heading Uppercase | IBM Plex Sans Variable | 20px | 700 | 1.40 | 0px | Uppercase transform for labels |
| Body Emphasis | IBM Plex Sans Variable | 19.3px | 600 | 1.56 | -0.48px | Semi-bold callout text |
| Label Uppercase | IBM Plex Sans Variable | 18px | 700 | 1.50 | 0px | Uppercase category labels |
| Body Semi | IBM Plex Sans Variable | 18px | 600 | 1.56 | 0px | Semi-bold body text |
| Body | IBM Plex Sans Variable | 16px | 400 | 1.50 | 0px | Standard reading text |
| Body Medium | IBM Plex Sans Variable | 16px | 500 | 1.50 | 0px | Medium-weight body |
| Body Relaxed | IBM Plex Sans Variable | 15px | 400 | 1.71 | 0px | Relaxed line-height for long reads |
| Nav / UI | IBM Plex Sans Variable | 15px | 600 | 1.50 | 0px | Navigation and UI labels |
| Caption | IBM Plex Sans Variable | 14px | 400–700 | 1.43 | 0px | Small text, various weights |
| Small Label | IBM Plex Sans Variable | 13px | 500–700 | 1.00–1.50 | 0px | Tags, badges, micro labels |
| Micro | IBM Plex Sans Variable | 12px | 400–700 | 1.33 | 0px | Smallest text, some uppercase |
| Code | Source Code Pro | 14px | 500 | 1.43 | 0px | Code snippets and terminal |
### Principles
- **Bold heading dominance**: Headings use 700–800 weight — PostHog's typography is confident and assertive, not whispery
- **Generous body line-heights**: Body text at 1.50–1.71 line-height creates extremely comfortable reading — the site is content-heavy and optimized for long sessions
- **Fractional sizes**: Several sizes (21.4px, 19.3px, 13.7px) suggest a fluid/scaled type system rather than fixed stops — likely computed from Tailwind's rem scale at non-standard base
- **Uppercase as category signal**: Bold uppercase labels (18px–20px weight 700) are used for product category headings — a magazine-editorial convention
- **Selective negative tracking**: Letter-spacing tightens on display text (-0.75px at 30px) but relaxes to 0px on body — headlines compress, body breathes
## 4. Component Stylings
### Buttons
- **Dark Primary**: `#1e1f23` background, white text, 6px radius, `10px 12px` padding. Hover: opacity 0.7 with Amber Gold text. Active: opacity 0.8 with slight scale transform. The main CTA — dark and confident
- **Sage Light**: `#e5e7e0` background, Olive Ink (`#4d4f46`) text, 4px radius, `4px` padding. Hover: `#f4f4f4` bg with PostHog Orange text. Compact utility button
- **Warm Tan Featured**: `#d4c9b8` background, black text, no visible radius. Hover: same orange text flash. Featured/premium actions
- **Input-style**: `#eeefe9` background, Sage Placeholder (`#9ea096`) text, 4px radius, 1px `#b6b7af` border. Looks like a search/filter control
- **Near-white Ghost**: `#fdfdf8` background, Olive Ink text, 4px radius, transparent 1px border. Minimal presence
- **Hover pattern**: All buttons flash PostHog Orange (`#F54E00`) or Amber Gold (`#F7A501`) text on hover — the brand's signature interaction surprise
### Cards & Containers
- **Bordered Card**: Warm Parchment (`#fdfdf8`) or white background, 1px `#bfc1b7` border, 4px–6px radius — clean and minimal
- **Sage Surface Card**: `#eeefe9` background for secondary content containers
- **Shadow Card**: `0px 25px 50px -12px rgba(0, 0, 0, 0.25)` — a single deep shadow for elevated content (modals, dropdowns)
- **Hover**: Orange text flash on interactive cards — consistent with button behavior
### Inputs & Forms
- **Default**: `#eeefe9` background, `#9ea096` placeholder text, 1px `#b6b7af` border, 4px radius, `2px 0px 2px 8px` padding
- **Focus**: `#3b82f6` ring at 50% opacity (Tailwind blue focus ring)
- **Text color**: `#374151` for input values — darker than primary text for readability
- **Border variations**: Multiple border patterns — some inputs use compound borders (top, left, bottom-only)
### Navigation
- **Top nav**: Warm background, IBM Plex Sans at 15px weight 600
- **Dropdown menus**: Rich mega-menu structure with product categories
- **Link color**: Deep Olive (`#23251d`) for nav links, underline on hover
- **CTA**: Dark Primary button (#1e1f23) in the nav — "Get started - free"
- **Mobile**: Collapses to hamburger with simplified menu
### Image Treatment
- **Hand-drawn illustrations**: Hedgehog mascot and quirky illustrations — the signature visual element
- **Product screenshots**: UI screenshots embedded in device frames or clean containers
- **Action figures**: Playful product photography of hedgehog figurines — anti-corporate
- **Trust logos**: Enterprise logos (Airbus, GOV.UK) displayed in a muted trust bar
- **Aspect ratios**: Mixed — illustrations are irregular, screenshots are 16:9 or widescreen
### AI Chat Widget
- Floating PostHog AI assistant with speech bubble — an interactive product demo embedded in the marketing site
## 5. Layout Principles
### Spacing System
- **Base unit**: 8px
- **Scale**: 2px, 4px, 6px, 8px, 10px, 12px, 16px, 18px, 24px, 32px, 34px
- **Section padding**: 32px–48px vertical between sections (compact for a content-heavy site)
- **Card padding**: 4px–12px internal (notably compact)
- **Component gaps**: 4px–8px between related elements
### Grid & Container
- **Max width**: 1536px (largest breakpoint), with content containers likely 1200px–1280px
- **Column patterns**: Varied — single column for text content, 2-3 column grids for feature cards, asymmetric layouts for product demos
- **Breakpoints**: 13 defined — 1px, 425px, 482px, 640px, 768px, 767px, 800px, 900px, 1024px, 1076px, 1160px, 1280px, 1536px
### Whitespace Philosophy
- **Content-dense by design**: PostHog's site is information-rich — whitespace is measured, not lavish
- **Editorial pacing**: Content sections flow like a magazine with varied layouts keeping the eye moving
- **Illustrations as breathing room**: Hand-drawn hedgehog art breaks up dense content sections naturally
### Border Radius Scale
- **2px**: Small inline elements, tags (`span`)
- **4px**: Primary UI components — buttons, inputs, dropdowns, menu items (`button`, `div`, `combobox`)
- **6px**: Secondary containers — larger buttons, list items, card variants (`button`, `div`, `li`)
- **9999px**: Pill shape — badges, status indicators, rounded tags (`span`, `div`)
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Level 0 (Flat) | No shadow, warm parchment background | Page canvas, most surfaces |
| Level 1 (Border) | `1px solid #bfc1b7` (Sage Border) | Card containment, input borders, section dividers |
| Level 2 (Compound Border) | Multiple 1px borders on different sides | Input groupings, toolbar elements |
| Level 3 (Deep Shadow) | `0px 25px 50px -12px rgba(0, 0, 0, 0.25)` | Modals, floating elements, mega-menu dropdowns |
### Shadow Philosophy
PostHog's elevation system is remarkably minimal — only one shadow definition exists in the entire system. Depth is communicated through:
- **Border containment**: Sage-tinted borders (`#bfc1b7`) at 1px create gentle warm separation
- **Surface color shifts**: Moving from `#fdfdf8` to `#eeefe9` to `#e5e7e0` creates layered depth without shadows
- **The single shadow**: The one defined shadow (`0 25px 50px -12px`) is reserved for floating elements — modals, dropdowns, popovers. It's a deep, dramatic shadow that creates clear separation when needed
### Decorative Depth
- **Illustration layering**: Hand-drawn hedgehog art creates visual depth naturally
- **No gradients or glow**: The flat, warm surface system relies entirely on border and surface-color differentiation
- **No glassmorphism**: Fully opaque surfaces throughout
## 7. Do's and Don'ts
### Do
- Use the olive/sage color family (#4d4f46, #23251d, #bfc1b7) for text and borders — the warm green undertone is essential to the brand
- Flash PostHog Orange (#F54E00) on hover states — it's the hidden brand signature
- Use IBM Plex Sans at bold weights (700/800) for headings — the font carries technical credibility
- Keep body text at generous line-heights (1.50–1.71) — the content-heavy site demands readability
- Maintain the warm parchment background (#fdfdf8) — not pure white, never cold
- Use 4px border-radius for most UI elements — keep corners subtle and functional
- Include playful, hand-drawn illustration elements — the personality is the differentiator
- Apply opacity-based hover states (0.7 opacity) on dark buttons rather than color shifts
### Don't
- Use blue, purple, or typical tech-SaaS colors — PostHog's palette is deliberately olive/sage
- Add heavy shadows — the system uses one shadow for floating elements only; everything else uses borders
- Make the design look "polished" or "premium" in a conventional sense — PostHog's charm is its irreverent, scrappy energy
- Use tight line-heights on body text — the generous 1.50+ spacing is essential for the content-heavy layout
- Apply large border-radius (12px+) on cards — PostHog uses 4px–6px, keeping things tight and functional
- Remove the orange hover flash — it's a core interaction pattern, not decoration
- Replace illustrations with stock photography — the hand-drawn hedgehog art is the brand
- Use pure white (#ffffff) as page background — the warm sage-cream (#fdfdf8) tint is foundational
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile Small | <425px | Single column, compact padding, stacked cards |
| Mobile | 425px–640px | Slight layout adjustments, larger touch targets |
| Tablet | 640px–768px | 2-column grids begin, nav partially visible |
| Tablet Large | 768px–1024px | Multi-column layouts, expanded navigation |
| Desktop | 1024px–1280px | Full layout, 3-column feature grids, expanded mega-menu |
| Large Desktop | 1280px–1536px | Max-width container, generous margins |
| Extra Large | >1536px | Centered container at max-width |
### Touch Targets
- Buttons: 4px–6px radius with `4px–12px` padding — compact but usable
- Nav links: 15px text at weight 600 with adequate padding
- Mobile: Hamburger menu with simplified navigation
- Inputs: Generous vertical padding for thumb-friendly forms
### Collapsing Strategy
- **Navigation**: Full mega-menu with dropdowns → hamburger menu on mobile
- **Feature grids**: 3-column → 2-column → single column stacked
- **Typography**: Display sizes reduce across breakpoints (30px → smaller)
- **Illustrations**: Scale within containers, some may hide on mobile for space
- **Section spacing**: Reduces proportionally while maintaining readability
### Image Behavior
- Illustrations scale responsively within containers
- Product screenshots maintain aspect ratios
- Trust logos reflow into multi-row grids on mobile
- AI chat widget may reposition or simplify on small screens
## 9. Agent Prompt Guide
### Quick Color Reference
- Primary Text: Olive Ink (`#4d4f46`)
- Dark Text: Deep Olive (`#23251d`)
- Hover Accent: PostHog Orange (`#F54E00`)
- Dark CTA: Near-Black (`#1e1f23`)
- Button Surface: Light Sage (`#e5e7e0`)
- Page Background: Warm Parchment (`#fdfdf8`)
- Border: Sage Border (`#bfc1b7`)
- Placeholder: Sage Placeholder (`#9ea096`)
### Example Component Prompts
- "Create a hero section on warm parchment background (#fdfdf8) with 30px IBM Plex Sans heading at weight 800, line-height 1.20, letter-spacing -0.75px, olive ink text (#4d4f46), and a dark CTA button (#1e1f23, 6px radius, white text, opacity 0.7 on hover)"
- "Design a feature card with #fdfdf8 background, 1px #bfc1b7 border, 4px radius, IBM Plex Sans heading at 20px weight 700, and 16px body text at weight 400 with 1.50 line-height in olive ink (#4d4f46)"
- "Build a navigation bar with warm background, IBM Plex Sans links at 15px weight 600 in deep olive (#23251d), underline on hover, and a dark CTA button (#1e1f23) at the right"
- "Create a button group: primary dark (#1e1f23, white text, 6px radius), secondary sage (#e5e7e0, #4d4f46 text, 4px radius), and ghost/text button — all flash #F54E00 orange text on hover"
- "Design an input field with #eeefe9 background, 1px #b6b7af border, 4px radius, #9ea096 placeholder text, focus ring in #3b82f6 at 50% opacity"
### Iteration Guide
When refining existing screens generated with this design system:
1. Verify the background is warm parchment (#fdfdf8) not pure white — the sage-cream warmth is essential
2. Check that all text uses the olive family (#4d4f46, #23251d) not pure black or neutral gray
3. Ensure hover states flash PostHog Orange (#F54E00) — if hovering feels bland, you're missing this
4. Confirm borders use sage-tinted gray (#bfc1b7) not neutral gray — warmth runs through every element
5. The overall tone should feel like a fun, scrappy startup wiki — never corporate-polished or sterile

# Design System Inspired by Raycast
> Category: Developer Tools
> Productivity launcher. Sleek dark chrome, vibrant gradient accents.
## 1. Visual Theme & Atmosphere
Raycast's marketing site feels like the dark interior of a precision instrument — a Swiss watch case carved from obsidian. The background isn't just dark, it's an almost-black blue-tint (`#07080a`) that creates a sense of being inside a macOS native application rather than a website. Every surface, every border, every shadow is calibrated to evoke the feeling of a high-performance desktop utility: fast, minimal, trustworthy.
The signature move is the layered shadow system borrowed from macOS window chrome: multi-layer box-shadows with inset highlights that simulate physical depth, as if cards and buttons are actual pressed or raised glass elements on a dark desk. Combined with Raycast Red (`#FF6363`) — deployed almost exclusively in the hero's iconic diagonal stripe pattern — the palette creates a brand that reads as "powerful tool with personality." The red doesn't dominate; it punctuates.
Inter is used everywhere — headings, body, buttons, captions — with extensive OpenType features (`calt`, `kern`, `liga`, `ss03`) creating a consistent, readable typographic voice. The positive letter-spacing (0.2px–0.4px on body text) is unusual for a dark UI and gives the text an airy, breathable quality that counterbalances the dense, dark surfaces. GeistMono appears for code elements, reinforcing the developer-tool identity.
**Key Characteristics:**
- Near-black blue-tinted background (`#07080a`) — not pure black, subtly blue-shifted
- macOS-native shadow system with multi-layer inset highlights simulating physical depth
- Raycast Red (`#FF6363`) as a punctuation color — hero stripes, not pervasive
- Inter with positive letter-spacing (0.2px) for an airy, readable dark-mode experience
- Radix UI component primitives powering the interaction layer
- Subtle rgba white borders (0.06–0.1 opacity) for containment on dark surfaces
- Keyboard shortcut styling with gradient key caps and heavy shadows
## 2. Color Palette & Roles
### Primary
- **Near-Black Blue** (`#07080a`): Primary page background — the foundational void with a subtle blue-cold undertone
- **Pure White** (`#ffffff`): Primary heading text, high-emphasis elements
- **Raycast Red** (`#FF6363` / `hsl(0, 100%, 69%)`): Brand accent — hero stripes, danger states, critical highlights
### Secondary & Accent

### Gradient System
- **Keyboard Key Gradient**: Linear gradient from `#121212` (top) to `#0d0d0d` (bottom) — simulates physical key depth
- **Warm Glow**: `rgba(215, 201, 175, 0.05)` radial spread — subtle warm ambient glow behind featured elements
## 3. Typography Rules
### Font Family
- **Primary**: `Inter` — humanist sans-serif, used everywhere. Fallbacks: `Inter Fallback`, system sans-serif
- **System**: `SF Pro Text` — Apple system font for select macOS-native UI elements. Fallbacks: `SF Pro Icons`, `Inter`, `Inter Fallback`
- **Monospace**: `GeistMono` — Vercel's monospace font for code elements. Fallbacks: `ui-monospace`, `SFMono-Regular`, `Roboto Mono`, `Menlo`, `Monaco`
- **OpenType features**: `calt`, `kern`, `liga`, `ss03` enabled globally; `ss02`, `ss08` on display text; `liga` disabled (`"liga" 0`) on hero headings
### Hierarchy
| Role | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|--------|-------------|----------------|-------|
| Display Hero | 64px | 600 | 1.10 | 0px | OpenType: liga 0, ss02, ss08 |
| Section Display | 56px | 400 | 1.17 | 0.2px | OpenType: calt, kern, liga, ss03 |
| Section Heading | 24px | 500 | normal | 0.2px | OpenType: calt, kern, liga, ss03 |
| Card Heading | 22px | 400 | 1.15 | 0px | OpenType: calt, kern, liga, ss03 |
| Sub-heading | 20px | 500 | 1.60 | 0.2px | Relaxed line-height for readability |
| Body Large | 18px | 400 | 1.15 | 0.2px | OpenType: calt, kern, liga, ss03 |
| Body | 16px | 500 | 1.60 | 0.2px | Primary body text, relaxed rhythm |
| Body Tight | 16px | 400 | 1.15 | 0.1px | UI labels, compact contexts |
| Button | 16px | 600 | 1.15 | 0.3px | Semibold, slightly wider tracking |
| Nav Link | 16px | 500 | 1.40 | 0.3px | Links in navigation |
| Caption | 14px | 500 | 1.14 | 0.2px | Small labels, metadata |
| Caption Bold | 14px | 600 | 1.40 | 0px | Emphasized captions |
| Small | 12px | 600 | 1.33 | 0px | Badges, tags, micro-labels |
| Small Link | 12px | 400 | 1.50 | 0.4px | Footer links, fine print |
| Code | 14px (GeistMono) | 500 | 1.60 | 0.3px | Code blocks, technical content |
| Code Small | 12px (GeistMono) | 400 | 1.60 | 0.2px | Inline code, terminal output |
### Principles
- **Positive tracking on dark**: Unlike most dark UIs that use tight or neutral letter-spacing, Raycast applies +0.2px to +0.4px — creating an airy, readable feel that compensates for the dark background
- **Weight 500 as baseline**: Most body text uses medium weight (500), not regular (400) — subtle extra heft improves legibility on dark surfaces
- **Display restraint**: Hero text at 64px/600 is confident but not oversized — Raycast avoids typographic spectacle in favor of functional elegance
- **OpenType everywhere**: `ss03` (stylistic set 3) is enabled globally across Inter, giving the typeface a slightly more geometric, tool-like quality
## 4. Component Stylings
### Buttons
- **Primary Pill**: Transparent background, white text, pill shape (86px radius), multi-layer inset shadow (`rgba(255, 255, 255, 0.1) 0px 1px 0px 0px inset`). Hover: opacity 0.6
- **Secondary Button**: Transparent background, white text, 6px radius, `1px solid rgba(255, 255, 255, 0.1)` border, subtle drop shadow (`rgba(0, 0, 0, 0.03) 0px 7px 3px`). Hover: opacity 0.6
- **Ghost Button**: No background or border, gray text (`#6a6b6c`), 86px radius, same inset shadow. Hover: opacity 0.6, text brightens to white
- **CTA (Download)**: Semi-transparent white background (`hsla(0, 0%, 100%, 0.815)`), dark text (`#18191a`), pill shape. Hover: full white background (`hsl(0, 0%, 100%)`)
- **Transition**: All buttons use opacity transition for hover rather than background-color change — a signature Raycast interaction pattern
### Cards & Containers
- **Standard Card**: `#101111` surface, `1px solid rgba(255, 255, 255, 0.06)` border, 12px–16px border-radius
- **Elevated Card**: Ring shadow `rgb(27, 28, 30) 0px 0px 0px 1px` outer + `rgb(7, 8, 10) 0px 0px 0px 1px inset` inner — creates a double-ring containment
- **Feature Card**: 16px–20px border-radius, subtle warm glow (`rgba(215, 201, 175, 0.05) 0px 0px 20px 5px`) behind hero elements
- **Hover**: Cards brighten slightly via border opacity increase or subtle shadow enhancement
### Inputs & Forms
- Dark input fields with `#07080a` background, `1px solid rgba(255, 255, 255, 0.08)` border, 8px border-radius
- Focus state: Border brightens, blue glow (`hsla(202, 100%, 67%, 0.15)`) ring appears
- Text: `#f9f9f9` input color, `#6a6b6c` placeholder
- Labels: `#9c9c9d` at 14px weight 500
### Navigation
- **Top nav**: Dark background blending with page, white text links at 16px weight 500
- **Nav links**: Gray text (`#9c9c9d`) → white on hover, underline decoration on hover
- **CTA button**: Semi-transparent white pill at nav end
- **Mobile**: Collapses to hamburger, maintains dark theme
- **Sticky**: Nav fixed at top with subtle border separator
### Image Treatment
- **Product screenshots**: macOS window chrome style — rounded corners (12px), deep shadows simulating floating windows
- **Full-bleed sections**: Dark screenshots blend seamlessly into the dark background
- **Hero illustration**: Diagonal stripe pattern in Raycast Red — abstract, geometric, brand-defining
- **App UI embeds**: Showing actual Raycast command palette and extensions — product as content
### Keyboard Shortcut Keys
- **Key cap styling**: Gradient background (`#121212` → `#0d0d0d`), heavy multi-layer shadow (`rgba(0, 0, 0, 0.4) 0px 1.5px 0.5px 2.5px` + inset shadows), creating realistic physical key appearance
- Border-radius: 4px–6px for individual keys
### Badges & Tags
- **Neutral badge**: `#1b1c1e` background, white text, 6px radius, 14px font at weight 500, `0px 6px` padding
- Compact, pill-like treatment for categorization
## 5. Layout Principles
### Spacing System
- **Base unit**: 8px
- **Scale**: 1px, 2px, 3px, 4px, 8px, 10px, 12px, 16px, 20px, 24px, 32px, 40px
- **Section padding**: 80px–120px vertical between major sections
- **Card padding**: 16px–32px internal spacing
- **Component gaps**: 8px–16px between related elements
### Grid & Container
- **Max width**: ~1200px container (breakpoint at 1204px), centered
- **Column patterns**: Single-column hero, 2–3 column feature grids, full-width showcase sections
- **App showcase**: Product UI presented in centered window frames
### Whitespace Philosophy
- **Dramatic negative space**: Sections float in vast dark void, creating cinematic pacing between features
- **Dense product, sparse marketing**: The product UI screenshots are information-dense, but the surrounding marketing copy uses minimal text with generous spacing
- **Vertical rhythm**: Consistent 24px–32px gaps between elements within sections
### Border Radius Scale
- **2px–3px**: Micro-elements, code spans, tiny indicators
- **4px–5px**: Keyboard keys, small interactive elements
- **6px**: Buttons, badges, tags — the workhorse radius
- **8px**: Input fields, inline components
- **9px–11px**: Images, medium containers
- **12px**: Standard cards, product screenshots
- **16px**: Large cards, feature sections
- **20px**: Hero cards, prominent containers
- **86px+**: Pill buttons, nav CTAs — full pill shape
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Level 0 (Void) | No shadow, `#07080a` surface | Page background |
| Level 1 (Subtle) | `rgba(0, 0, 0, 0.28) 0px 1.189px 2.377px` | Minimal lift, inline elements |
| Level 2 (Ring) | `rgb(27, 28, 30) 0px 0px 0px 1px` outer + `rgb(7, 8, 10) 0px 0px 0px 1px inset` inner | Card containment, double-ring technique |
| Level 3 (Button) | `rgba(255, 255, 255, 0.05) 0px 1px 0px 0px inset` + `rgba(255, 255, 255, 0.25) 0px 0px 0px 1px` + `rgba(0, 0, 0, 0.2) 0px -1px 0px 0px inset` | macOS-native button press — white highlight top, dark inset bottom |
| Level 4 (Key) | 5-layer shadow stack with inset press effects | Keyboard shortcut key caps — physical 3D appearance |
| Level 5 (Floating) | `rgba(0, 0, 0, 0.5) 0px 0px 0px 2px` + `rgba(255, 255, 255, 0.19) 0px 0px 14px` + insets | Command palette, floating panels — heavy depth with glow |
### Shadow Philosophy
Raycast's shadow system is the most macOS-native on the web. Multi-layer shadows combine:
- **Outer rings** for containment (replacing traditional borders)
- **Inset top highlights** (`rgba(255, 255, 255, 0.05–0.25)`) simulating light source from above
- **Inset bottom darks** (`rgba(0, 0, 0, 0.2)`) simulating shadow underneath
- The effect is physical: elements feel like glass or brushed metal, not flat rectangles
### Decorative Depth
- **Warm glow**: `rgba(215, 201, 175, 0.05) 0px 0px 20px 5px` behind featured elements — a subtle warm aura on the cold dark canvas
- **Blue info glow**: `rgba(0, 153, 255, 0.15)` for interactive state emphasis
- **Red danger glow**: `rgba(255, 99, 99, 0.15)` for error/destructive state emphasis
## 7. Do's and Don'ts
### Do
- Use `#07080a` (not pure black) as the background — the blue-cold tint is essential to the Raycast feel
- Apply positive letter-spacing (+0.2px) on body text — this is deliberately different from most dark UIs
- Use multi-layer shadows with inset highlights for interactive elements — the macOS-native depth is signature
- Keep Raycast Red (`#FF6363`) as punctuation, not pervasive — reserve it for hero moments and error states
- Use `rgba(255, 255, 255, 0.06)` borders for card containment — barely visible, structurally essential
- Apply weight 500 as the body text baseline — medium weight improves dark-mode legibility
- Use pill shapes (86px+ radius) for primary CTAs, rectangular shapes (6px–8px) for secondary actions
- Enable OpenType features `calt`, `kern`, `liga`, `ss03` on all Inter text
- Use opacity transitions (hover: opacity 0.6) for button interactions, not color changes
### Don't
- Use pure black (`#000000`) as the background — the blue tint differentiates Raycast from generic dark themes
- Apply negative letter-spacing on body text — Raycast deliberately uses positive spacing for readability
- Use Raycast Blue as the primary accent for everything — blue is for interactive/info, red is the brand color
- Create single-layer flat shadows — the multi-layer inset system is core to the macOS-native aesthetic
- Use regular weight (400) for body text when 500 is available — the extra weight prevents dark-mode text from feeling thin
- Mix warm and cool borders — stick to the cool gray (`hsl(195, 5%, 15%)`) border palette
- Apply heavy drop shadows without inset companions — shadows always come in pairs (outer + inset)
- Use decorative elements, gradients, or colorful backgrounds — the dark void is the stage, content is the performer
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | <600px | Single column, stacked cards, hamburger nav, hero text reduces to ~40px |
| Small Tablet | 600px–768px | 2-column grid begins, nav partially visible |
| Tablet | 768px–1024px | 2–3 column features, nav expanding, screenshots scale |
| Desktop | 1024px–1200px | Full layout, all nav links visible, 64px hero display |
| Large Desktop | >1200px | Max-width container centered, generous side margins |
### Touch Targets
- Pill buttons: 86px radius with 20px padding — well above 44px minimum
- Secondary buttons: 8px padding minimum, but border provides visual target expansion
- Nav links: 16px text with surrounding padding for accessible touch targets
### Collapsing Strategy
- **Navigation**: Full horizontal nav → hamburger at mobile with slide-out menu
- **Hero**: 64px display → 48px → 36px across breakpoints
- **Feature grids**: 3-column → 2-column → single-column stack
- **Product screenshots**: Scale within containers, maintaining macOS window chrome proportions
- **Keyboard shortcut displays**: Simplify or hide on mobile where keyboard shortcuts are irrelevant
### Image Behavior
- Product screenshots scale responsively within fixed-ratio containers
- Hero diagonal stripe pattern scales proportionally
- macOS window chrome rounded corners maintained at all sizes
- No lazy-loading artifacts — images are critical to the product narrative
## 9. Agent Prompt Guide
### Quick Color Reference
- Primary Background: Near-Black Blue (`#07080a`)
- Primary Text: Near White (`#f9f9f9`)
- Brand Accent: Raycast Red (`#FF6363`)
- Interactive Blue: Raycast Blue (`hsl(202, 100%, 67%)` / ~`#55b3ff`)
- Secondary Text: Medium Gray (`#9c9c9d`)
- Card Surface: Surface 100 (`#101111`)
- Border: Dark Border (`hsl(195, 5%, 15%)` / ~`#252829`)
### Example Component Prompts
- "Create a hero section on #07080a background with 64px Inter heading (weight 600, line-height 1.1), near-white text (#f9f9f9), and a semi-transparent white pill CTA button (hsla(0,0%,100%,0.815), 86px radius, dark text #18191a)"
- "Design a feature card with #101111 background, 1px solid rgba(255,255,255,0.06) border, 16px border-radius, double-ring shadow (rgb(27,28,30) 0px 0px 0px 1px outer), 22px Inter heading, and #9c9c9d body text"
- "Build a navigation bar on dark background (#07080a), Inter links at 16px weight 500 in #9c9c9d, hover to white, and a translucent white pill button at the right end"
- "Create a keyboard shortcut display with key caps using gradient background (#121212→#0d0d0d), 5-layer shadow for physical depth, 4px radius, Inter 12px weight 600 text"
- "Design an alert card with #101111 surface, Raycast Red (#FF6363) left border accent, translucent red glow (hsla(0,100%,69%,0.15)), white heading, and #cecece description text"
### Iteration Guide
When refining existing screens generated with this design system:
1. Check the background is `#07080a` not pure black — the blue tint is critical
2. Verify letter-spacing is positive (+0.2px) on body text — negative spacing breaks the Raycast aesthetic
3. Ensure shadows have both outer and inset layers — single-layer shadows look flat and wrong
4. Confirm Inter has OpenType features `calt`, `kern`, `liga`, `ss03` enabled
5. Test that hover states use opacity transitions (0.6) not color swaps — this is a core interaction pattern

# Design System Inspired by Refined
> Category: Modern & Minimal
> Carefully curated, modern minimal style with elegant serif typography and understated, sophisticated palettes.
## 1. Visual Theme & Atmosphere
Carefully curated, modern minimal style with elegant serif typography and understated, sophisticated palettes.
- **Visual style:** modern, minimal
- **Color stance:** primary, neutral, success, warning, danger
- **Design intent:** Keep outputs recognizable to this style family while preserving usability and readability.
## 2. Color
- **Primary:** `#3B82F6` — Token from style foundations.
- **Secondary:** `#8B5CF6` — Token from style foundations.
- **Success:** `#16A34A` — Token from style foundations.
- **Warning:** `#D97706` — Token from style foundations.
- **Danger:** `#DC2626` — Token from style foundations.
- **Surface:** `#FFFFFF` — Token from style foundations.
- **Text:** `#111827` — Token from style foundations.
- **Neutral:** `#FFFFFF` — Derived from the surface token for official format compatibility.
- Favor Primary (#3B82F6) for CTA emphasis.
- Use Surface (#FFFFFF) for large backgrounds and cards.
- Keep body copy on Text (#111827) for legibility.
## 3. Typography
- **Scale:** 12/14/16/20/24/32
- **Families:** primary=Playfair Display, display=Playfair Display, mono=JetBrains Mono
- **Weights:** 100, 200, 300, 400, 500, 600, 700, 800, 900
- Headings should carry the style personality; body text should optimize scanability and contrast.
## 4. Spacing & Grid
- **Spacing scale:** 4/8/12/16/24/32
- Keep vertical rhythm consistent across sections and components.
- Align columns and modules to a predictable grid; avoid ad-hoc offsets.
## 5. Layout & Composition
- Prefer clear content blocks with consistent internal padding.
- Keep hierarchy obvious: headline → support text → primary action.
- Use whitespace to separate concerns before adding borders or shadows.
## 6. Components
- Buttons: primary action uses `#3B82F6`; secondary actions stay neutral.
- Inputs: strong focus-visible states, clear labels, and predictable error messaging.
- Cards/sections: use consistent radii, spacing, and elevation strategy across the page.
## 7. Motion & Interaction
- Use subtle transitions that emphasize Primary (#3B82F6) as the interaction signal.
- Default to short, purposeful transitions (150–250ms) with stable easing.
- Ensure hover, focus-visible, active, disabled, and loading states are explicit.
## 8. Voice & Brand
- Tone should reflect the visual style: concise, confident, and product-specific.
- Keep microcopy action-oriented and avoid generic filler language.
- Preserve the style identity in headlines while keeping UI labels literal and clear.
## 9. Anti-patterns
- Do not introduce off-palette colors when an existing token can solve the problem.
- Do not flatten hierarchy by using the same type size/weight for all text.
- Do not add decorative effects that reduce readability or accessibility.
- Do not mix unrelated visual metaphors in the same interface.
