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
- Replace from:"random" with from:"center" stagger in us-map,
world-map, spain-map — random stagger is non-deterministic across
parallel render workers, causing visual jumps at chunk boundaries.
- Exempt type="importmap" and type="module" inline scripts from the
invalid_inline_script_syntax lint rule. The rule used new Function()
to parse, which rejects import statements and JSON import maps.
Closes#929.
- Cache-bust all map MDX preview video URLs after re-rendering with
the deterministic stagger fix.
New block: spain-map — animated Spain choropleth by autonomous
community using D3 conic conformal projection with GDP per capita
data and red-to-amber color scale.
Also switches all map MDX preview URLs from S3 to local paths
so they render in mintlify dev without needing S3 upload first.
