/* Fonts are self-hosted local woff2, tight-subset to the glyphs this page
   actually uses. Weights are declared only where a cut exists; the browser
   must never synthesise a project face.

   font-display:block on the two cuts the first screen paints (Vazirmatn 400
   text, 700 headline). Everything else is swap: below the fold nobody watches
   it arrive, and every era change is gated on readiness anyway. This site's
   product IS the typeface, so the hero waits blank for a beat rather than
   appearing in the wrong face. */
