dev 44514c3cc1 fix(carousel): vertical overflow + close gaps vs embla/ark-ui/mantine ... Real reference audit walked the published embla `.d.ts`, Mantine docs, ark-ui, shadcn-svelte and Swiper. Found three classes of gaps in the initial port (a) the vertical bug breaking the only non-default orientation, (b) layout primitives every other lib ships (slidesPerView, slidesToScroll, align, gap), (c) autoplay granularity (playOnInit, stopOnInteraction, stopOnFocusIn, stopOnMouseEnter, stopOnLastSnap), plus an imperative API every consumer needs. ## Vertical bug fix Recipe now gives the root a default `block-size` in vertical orientation (`16rem`, overridable via `--_carousel-vertical-block-size` or the new eidos `verticalBlockSize` prop) and stretches the viewport to fill it. Without this the viewport collapses to content height and items spill. ## Soma extensions - `defaultValue` (uncontrolled init) - `slidesPerView` (1+) — each Item basis = (100% − gap·(n−1)) / n - `slidesToScroll` (1+) — paged group navigation - `align: 'start' | 'center' | 'end'` — viewport alignment - `gap: string` (CSS length) — between-slide spacing on the ItemGroup - `playOnInit` — start autoplay on mount (default true) - `stopOnInteraction` — latch-stop after user clicks prev/next/indicator or drags - `stopOnFocusIn` — pause while focus is inside (default true) - `stopOnMouseEnter` — pause while cursor over root (Embla parity) - `stopOnLastSnap` — latch-stop at last snap when loop=false - Snippet exposes `isPlaying` + an `api` handle with `scrollNext / scrollPrev / scrollTo / play / pause / reset` `commit()` now respects `slidesPerView` (last snap = count − spv). `next()` / `prev()` step by `slidesToScroll`. Translate calc derives from `slideSize = viewportSize / slidesPerView` so multi-view works. Item flex-basis adapts to slidesPerView + gap. ## Eidos additions - `verticalBlockSize` prop — forwarded as CSS custom property for the vertical recipe override - Recipe selectors for vertical orientation enforcing the block-size + viewport stretch - Style composition so consumers can still pass inline `style` ## Demo Live tab now has 4 organized sections (layout / drag / autoplay / imperative API) covering every new prop. The imperative API row drives the carousel from external buttons via the snippet handle so consumers see the pattern in action. `verticalBlockSize` slider exercises the vertical fix. Snippet preview emits every set prop. ## Reference comparison Following the canon's mandate to compare with references BEFORE declaring done, the actual feature matrix from embla published `.d.ts`, Mantine docs, ark-ui, shadcn-svelte, Swiper: | Feature | embla | mantine | ark | swiper | UIX | |------------------------|-------|---------|-----|--------|-----| | Index nav | ✓ | ✓ | ✓ | ✓ | ✓ | | Loop | ✓ | ✓ | ✓ | ✓ | ✓ | | Drag | ✓ | ✓ | ✓ | ✓ | ✓ | | Autoplay | plug | plug | ✓ | ✓ | ✓ | | Orientation H/V | ✓ | ✓ | ✓ | ✓ | ✓ | | slidesPerView | indir | ✓ | ✓ | ✓ | ✓ | | slidesToScroll | ✓ | ✓ | ✓ | ✓ | ✓ | | Align | ✓ | indir | per | ✓ | ✓ | | Gap | css | ✓ | ✓ | ✓ | ✓ | | defaultValue | startIndex | ✓ | ✓ | ✓ | ✓ | | playOnInit | ✓ | indir | ✓ | ✓ | ✓ | | stopOnInteraction | ✓ | ✓ | ✓ | ✓ | ✓ | | stopOnFocusIn | ✓ | ✓ | ✓ | partl | ✓ | | stopOnMouseEnter | ✓ | ✓ | ✓ | ✓ | ✓ | | stopOnLastSnap | ✓ | ✓ | ✗ | ✓ | ✓ | | Imperative API | ✓ | ✓ | ✓ | ✓ | ✓ | | Indicators / triggers | DIY | ✓ | ✓ | ✓ | ✓ | | Fade effect | plug | plug | ✗ | ✓ | ✗ deferred | | Virtual slides | ✗ | ✗ | ✗ | ✓ | ✗ deferred | | Multirow grid | ✗ | ✗ | ✗ | ✓ | ✗ deferred | Deferred power-user features (fade, virtual, multirow grid, cube/cards, parallax) are documented as power-user in the reference audit, not table-stakes, and would require Embla-class internals to ship.
