* fix(catalog): reveal Matrix Decode captions with autoAlpha so the docs preview renders
The demo and snippet flipped word spans with zero-duration display sets,
which the seek-driven docs player never applies after its style restore:
the composition played 8s of black. autoAlpha reveals with the scrambles
as same-length absolute overlays follow the keyframes contract (never
tween display) and survive seeks and loop wraps. Scramble text now
matches each word's length so it decodes in place instead of jumping.
* chore(registry): remove the Checkout Flow component
Owner-directed removal of the checkout-flow catalog item: source,
demo, generated docs page and payload, and its entries in the registry
manifest, catalog index, docs nav, and search vectors. The deletions
are allowlisted in check-no-main-deletions.
Caption components are overlays — their root element should not
intercept pointer events, allowing clicks to pass through to the
underlying composition content in Studio.
Replace opaque backgrounds (#0a0a0a, #000, #000000) with transparent
on both html/body and the composition root div for all 15 caption
components. Captions are overlays — opaque backgrounds cover the
underlying video when loaded as sub-compositions.
Timeline locking:
- Add data-timeline-locked attribute support — fully disables move,
trim-start, and trim-end in Studio for clips that carry this attr
- Runtime propagates the attribute from inner composition root to host
element so component authors control it from their HTML
- All 15 caption components in the registry now carry the attribute
Font fix:
- Extract <link rel="stylesheet"> and <link rel="preconnect"> from
sub-composition <head> alongside existing <style>/<script> extraction
- Fixes caption components (and any sub-comp using Google Fonts via
<link> tags) losing their font-family when loaded as sub-compositions
- Applied in both runtime (compositionLoader) and compiler
(inlineSubCompositions) paths
Adds a Blocks tab to the Studio left sidebar with the full 78-item registry
catalog (58 blocks + 20 components). Users can browse by category, search by
title/description, preview CDN-hosted poster thumbnails with video-on-hover,
and install items on-demand with one click or drag-to-timeline.
Core changes:
- BlockCategory type + resolveBlockCategory() for 7 categories (Captions, VFX,
Transitions, Effects, Social, Data, Scenes)
- Registry API routes: GET /api/registry/blocks (catalog) + POST install
- StudioApiAdapter extended with listRegistryCatalog + installRegistryBlock
- Vite adapter reads from disk; CLI adapter fetches from GitHub (24h cache)
- BlockParam interface + params on 6 blocks for future parameter controls
Studio UI:
- 4th sidebar tab "Blocks" with responsive grid, category pills, search bar
- BlockCard: CDN poster thumbnail, video autoplay on hover, duration + WebGL badges
- On-demand install: blocks append as sub-compositions on timeline; components
overlay at start=0 spanning full duration with transparent background patching
- TIMELINE_BLOCK_MIME drag-and-drop to timeline
- BlockParamsPanel (Phase 3 scaffold) auto-opens for parameterized blocks
Registry manifests:
- All 58 blocks backfilled with preview: { video, poster } CDN URLs
- All 20 components normalized to object format + poster URLs added
- 6 blocks annotated with params (Liquid Glass/Background, Portal, Chart,
Logo Outro, Magnetic)
- flowchart-vertical preview generated and uploaded to CDN
Upload re-rendered videos with -v2 filenames to bypass CloudFront
immutable cache. Replace gradient-fill with improved version from
sandbox composition.
- Fix timeline_id_mismatch on all 15 caption components: __timelines key
now matches data-composition-id (e.g. "caption-clip-wipe" not "clip-wipe")
- Regenerate docs/public/catalog-index.json with 15 new caption entries
- Add "Captions" group mapping to generate-catalog-pages.ts (priority 0)
- Regenerate docs.json nav and mdx pages via the catalog script
- Upload docs preview videos to docs/images CDN path
- Add 15 .mdx doc pages under docs/catalog/components/ for all caption styles
- Add "Captions" group as first section in the Catalog tab navigation
- Add canvas-based fitFontSize to 14 caption components to prevent text overflow
- Fix parallax-layers vertical clipping by repositioning the behind safe zone
- Re-render all 15 preview videos at high quality and upload to CDN
