/* FAAI · Self-hosted fonts
   ────────────────────────
   All font files served from /fonts/ on the same origin. Eliminates the
   third-party data leak that Google Fonts creates (visitor IP+UA sent to
   Google on every page view). GDPR-clean by default.

   Subsets: latin + latin-ext only — covers Slovenian (č, š, ž) and
   Croatian (č, ć, đ, š, ž) diacritics + Western European. Cyrillic /
   Vietnamese / Greek subsets that Google Fonts would have served are
   omitted — saves ~140KB of unused font data per visitor.

   font-display: swap means the browser paints fallback fonts immediately;
   headings don't wait for Geist to download.

   Instrument Serif was retired with the HLB redesign — Geist sans now
   carries every heading and the brand mark. */
