…or model swapping
- Rename block from magic-book to three-dissolve — the value is the
dissolve effect, not the specific spellbook model
- Add HyperFrames variables: modelUrl, dissolveStart, dissolveEnd,
particleColor, bgColor — users can now swap the GLTF model and
customize colors without editing the HTML
- Remove bundled binary assets (14MB of GLTF + textures) from the
repo; default model URL now points to static.heygen.ai CDN
- Fix readiness signal: replace window.__tailwindReady with
window.__hyperframes_ready
- Fix seeded random: use closure-scoped createSeededRandom() instead
of module-scope let seed to prevent shared state across instances
- Remove debug globals (window.__magicBookDebug, window.seekMagicBook)
- Use querySelector('[data-composition-id]') instead of getElementById
for compatibility with HyperFrames compiler inlining
- Add model-swapping documentation with data-var-modelUrl examples
Read variables from window.__hfVariablesByComp[compositionId] which is what the HyperFrames compiler populates from data-variable-values. Update docs to use data-variable-values (JSON) instead of data-var-*.
The HyperFrames runtime doesn't always populate __hfVariablesByComp before sub-composition scripts run. Fall back to reading data-variable-values directly from the composition's DOM element, which the compiler preserves.
Replace hardcoded root.scale.setScalar(0.34) (tuned for the spellbook) with bounding-box-based auto-scaling that centers the model and scales it to 32% of the camera's visible height. Any GLTF model now fills the frame consistently regardless of its native dimensions.

Summary
Builds on @MrSunOcean's work in #712 (magic-book block) and restructures it into a generic, model-swappable catalog block per the review feedback.
