## 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.
