OD simple-deck seed.
|
|
|
|
Single-file horizontal-swipe HTML deck. Each `<section class="slide">`
|
|
is one slide; the body uses CSS scroll-snap to lock to slide boundaries.
|
|
Keyboard nav (← / → / Space / Home / End) is wired in via the script at
|
|
the bottom — DO NOT replace it, it solves five iframe-specific problems
|
|
that the naive version silently breaks (see comments in the script).
|
|
|
|
Theme tokens at the top mirror the web-prototype seed; bind them to the
|
|
active DESIGN.md and stop. A deck has TWO surfaces — `.slide.light` and
|
|
`.slide.dark` — that swap fg / bg without touching the accent. Use both;
|
|
alternating creates the rhythm that prevents visual fatigue.

Five hard rules for deck nav inside an iframe (the OD preview is one).
|
|
The naive `document.body.scrollLeft` pattern silently fails: clicks
|
|
register, but keyboard does nothing, and the counter freezes at "1 / N"
|
|
while the user is on slide 6.
|
|
|
|
1. Detect the real scroller — body OR documentElement, depending.
|
|
2. Listen for scroll on BOTH window and document, capture phase.
|
|
3. Listen for keydown on BOTH window and document, capture phase.
|
|
4. Auto-focus body so arrow keys work without an upfront click.
|
|
5. Never use Element.scrollIntoView — it can yank the host page.
