- Register CanvasKit faces under their source family names so CJK and Arabic glyphs paint instead of only shaping metrics
- Add deterministic CJK, Arabic, mixed-script, first-paint, and interactive fallback image oracles
- Cover typed and tool-created text parity with a repository-owned Noto CJK subset
Fixes#324Fixes#291
- Gate ingest rendering until required faces and script fallbacks resolve
- Key CanvasKit artifacts by font registration generation and invalidate affected nodes
- Load character-aware remote subsets with cumulative coverage and exact render aliases
- Use BCP-47 language hints for shaping and CJK fallback order
- Keep baked .fig glyphs as an exhaustion-only fallback
- Resolve exact faces through registered, local, cache, and remote sources with deduplicated state transitions\n- Use CanvasKit notdef glyphs to request script fallbacks and repaint after resolution\n- Make CJK coverage analysis codepoint-safe across supplementary characters and style runs
