/* ============================================================================
   Apex Minds brand fonts — SELF-HOSTED, Cyrillic-first.

   Four families, and every one of them can set Ukrainian:
     Unbounded  — display (wordmark, hero, titles).      200–900 variable.
     Inter      — text and UI (everything else).          100–900 variable.
     Caveat     — the archive's editorial hand, only.     400–700 variable.
     CMU Serif  — a problem's own text (the math's face).  400/700 + italics.

   Fraunces and DM Sans were REMOVED on 2026-09-20. Both are Latin-only
   upstream, which meant the 59px Ukrainian hero silently rendered in Georgia
   and all Ukrainian body text fell through to an unspecified system face.
   A typeface enters this stack only if it sets «Олімпіадні задачі» in its own
   glyphs — see DESIGN.md, "The Cyrillic Test".

   Declared as variable ranges so one file per subset serves every weight the
   design system asks for; browsers fetch only the subsets a page needs, so a
   Ukrainian page pays for `cyrillic` and nothing else.

   To refresh: re-fetch the css2 + woff2 from Google Fonts and rewrite urls to
   ./files/ with a content hash in the filename.

   was Computer Modern. Set only where a problem's own text is (statement,
   answer, solution, editorial note, the featured and result snippets); the
   interface around it stays Inter.

   Subset from the OTFs with fontTools to Latin, Latin-1, Cyrillic (incl. ґ і ї
   є), Greek, general punctuation, № and ₴ — every character the published
   prose uses that the font has (87 of 9.4M prose characters, ≤ ≥ ⇒ and
   subscript digits, fall to KaTeX_Main next in the stack). Kerning, ligatures
   and locl kept. `cmunbx`/`cmunbi` are the Bold Extended cuts — Computer
   Modern's bold, which is what **bold** looks like in the printed books. */

   3 KB. .cflag names Apple / Noto emoji first, so macOS, iOS and Android keep
   their own flags and only Windows (and bare Linux) draws these.
   To add a country: drop the other ligatures from the package's GSUB, run
   `python3 -m fontTools.subset` with the flags as --text and
   --layout-features='*', and rename by content hash. Pruning GSUB first is the
   step that matters: with all 26 letters kept, the subsetter keeps every flag. */
