   Per ADR-0007: Inter + Noto Sans SC + JetBrains Mono,
   3 字重精简（400 / 700 / 900）, subset via unicode-range.

   Load BEFORE catlaxy-ds.css.

   Behavior:
   - Latin / digits / symbols → Inter (via unicode-range filter)
   - CJK ideographs            → Noto Sans SC (CJK-only subset, no Latin)
   - Monospace code            → JetBrains Mono (Latin)

   The font-stack in --f-cn puts Inter FIRST so that Latin
   chars inside Chinese text use Inter (not system fallback).

   Total size: ~2.6 MB across 7 woff2 files, loaded on-demand.
