/* ── Persian typography, self-hosted (Iran network independence) ─────────────
   The webfonts live in assets/fonts/ next to this stylesheet, so no CDN is
   contacted at paint time. jsdelivr / fonts.googleapis.com are frequently
   blocked or throttled in Iran without a VPN; a missing webfont must never
   block first paint, so `font-display: swap` renders the system fallback
   immediately and swaps in the real font once the local file arrives. */
/* Origin-absolute: a stylesheet is reachable from any route depth, so a
   relative "./fonts/..." resolves against the deepest path segment and the
   SPA fallback answers index.html instead of the font. Same class of bug as
   the one already fixed in index.html's script tags. */
