One block per loop variant (loop-<family>[-<n>], 1080x1080), one hand-written engine per family, driven by a single paused GSAP timeline that recomputes every card transform from t. Every engine parameter is exposed through data-composition-variables, grouped like a template editor's panel (Media / Background / Appearance / Animation / Template options), plus image1..N content slots that default to monochrome SVG placeholders. No third-party media ships. Validation: scripts/lint-registry-items.mjs 249/249, oxfmt clean, hyperframes check on one variant per family (95/95), registry.json + docs/catalog pages regenerated by the repo scripts. Previews are rendered locally (720^2) and need the docs-images upload. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
