/* =============================================================
   Adumbrate Design Kit — Self-hosted @font-face
   -------------------------------------------------------------
   Every face here is OFL-licensed (Inter, Noto, Source Serif) or
   OFL (Sarasa) and shipped in-repo, so the kit renders identically
   offline / airgapped. No CDN, no network, no Google Fonts call.

   Latin faces are variable (one file, full weight axis). CJK faces
   are gated by `unicode-range` so a Latin-only page never downloads
   the multi-megabyte Chinese files — the browser fetches them only
   when a CJK glyph is actually painted.

   File layout (produced by ../build/):
     fonts/inter/            Inter-roman.var.woff2, Inter-italic.var.woff2
     fonts/source-serif-4/   SourceSerif4-roman.var.woff2, -italic.var.woff2
     fonts/noto-sans-sc/     NotoSansSC.subset.woff2   (weight-variable, CJK subset)
     fonts/noto-serif-sc/    NotoSerifSC.subset.woff2  (weight-variable, CJK subset)
     fonts/sarasa-mono-sc/   SarasaMonoSC-Regular.woff2, -Bold.woff2, -Italic.woff2

   To (re)build the woff2 files: `make -C ../build fonts`  (runs in Docker).
   Each family folder also carries its upstream LICENSE file.
