## Why

Phase D content accumulation. The registry pipeline (PRs 6-10) is in place — this PR exercises it at scale.

## How

- Extracted from zip files in the Hyperframe Template Structure Notion doc
- Social overlays: single-file standalone HTML, copied directly
- Multi-file blocks (ascii-*, app-showcase, ui-3d-reveal): converted `<template>` sub-compositions to standalone HTML with proper `<!doctype>` wrappers
- All previews (PNG + MP4) rendered locally via `generate-catalog-previews.ts`
- Catalog MDX pages regenerated via `generate-catalog-pages.ts`
- `docs.json` updated with new catalog entries

## Test plan

- [x] All 11 blocks render to PNG + MP4 without errors
- [x] Catalog pages generated for all 17 items (14 blocks + 3 components)
- [x] `registry-item.json` files have correct dimensions, duration, tags
- [x] `oxfmt --check` passes on all files
