Module font 

v1.0 Phase C1 — bundled default fonts.

smix-annotate ships two fonts embedded via include_bytes! so text annotations work out of the box without any consumer-supplied font path:

• Inter Regular (~312 KB) — SIL Open Font License, from rsms/inter. Covers Latin + extended punctuation + Greek + Cyrillic.
• Noto Sans SC subset (~64 KB) — SIL Open Font License, from googlefonts/noto-cjk. Pre-subsetted to ~250 most-frequent CJK ideographs + ASCII + CJK punctuation. Covers typical QA/UI Chinese text in yaml annotations.

Routing

pick_font_for_codepoint(cp) returns the appropriate font bytes based on the Unicode range of cp:

• ASCII + Latin extended → Inter
• CJK Unified Ideographs + CJK punctuation → Noto Sans SC subset
• Everything else → Inter (fallback)

For per-glyph routing, Annotator::render iterates chars and picks the font per-codepoint, ensuring mixed-script text renders correctly.

Overriding

Callers can supply their own font via Annotator::font(bytes) — that overrides both bundled fonts for the entire annotator’s render pass. Use for corpus-specific glyph coverage.
