scot 928628f49a v0.3.0-alpha: Chromium rasterizer (R4), branching, chapters
- Rasterizer: playwright-core + system Chromium renders dom steps to PNG
  (1280x800, JavaScript disabled — snapshots stay inert). Cached permanently
  on the step (dom_html immutable). CHROMIUM_PATH configurable.
- Video render now includes DOM steps as real frames (verified h264 1280x800,
  0 skipped); guides now show rasterized screenshots for DOM steps
- Branching: per-step branch hotspots (dashed, labeled) jumping to any target
  step; lead gates respected on branch jumps
- Chapters: demo-level chapter menu in player bar
- API: PATCH /api/demos/:id (name, chapters), branches on step patch, both in
  public JSON
- MCP surface: 15 tools (+set_step_branches, +set_chapters)
- Docker: chromium + fonts in runtime image, CHROMIUM_PATH preset
