   Noto Sans JP / TC are loaded from Google Fonts because their full

/* ── Noto Sans JP / TC — CJK fallback ─────────────────────────────────
   The Google Fonts @import was REMOVED (2026-06-04). Production ships
   light-only, Latin-primary, and EU schools require no third-party font
   requests — so previews now load only the self-hosted Inter above and
   never make an external call. CJK text falls back to system-installed
   Noto Sans JP / TC (or the OS sans-serif) through the --eos-font-jp /
   --eos-font-zh-tc stacks. To self-host the real Noto woff2 for a CJK
   launch, follow the plan in README.md — only this file changes.

   The local() stubs below register the family names so the design-system
   compiler knows they are intentional. The browser resolves them from
   the OS font cache; if not installed, the fallback stack applies. No
   file upload or external request is made. */
