- CinematicRenderer.tsx / cinematic/types.ts: TitleCard now supports
  ghosted video background, word-by-word stagger reveal with blur->sharp
  transition, proper newline handling, and growing accent lines. Title
  scenes accept backgroundSrc/backgroundTrimBeforeSeconds/
  backgroundTrimAfterSeconds plus a plate|overlay variant.
- Add CollageBurst, LyricOverlay, ScreenshotScene components.
- Explainer, Root, components/index.ts wiring updates.
- SCENE_TYPES.md reflects the new components.
- seedance-2-0 skill + seedance_video.py: small fixes.
