- 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 #324 Fixes #291
