/* ===== FONTS (self-hosted) ===== */
/* Unbounded is a variable font: same WOFF2 covers weights 500–800,
   split by unicode-range so the browser only fetches the subset it needs.
   The -ext WOFF2 is subset (118KB -> ~5KB) to the Latin-Extended letters the
   headings use: the Slovak alphabet plus anything else found in heading text.
   The ext unicode-range below (and the ?v=) are GENERATED by
   tools/fonts/subset-unbounded-ext.mjs from the built site, so don't hand-edit
   them; instead edit content, `npm run build`, re-run that script, build again.
   A non-Slovak Latin-Extended char that only appears outside headings is not
   kept, and would fall back to a system font (graceful) rather than tofu. */
