/* ═══════════════════════════════════════════════════════════════════════
   bijan-fallah.com — one stylesheet, every page. Rebuilt 2026-10-08.

   One ivory ground, one serif, one mono for small labels. A single centred
   column, generous air, hairline borders, rounded cards. Mobile-first: the
   phone layout is the base and wider screens add room, never the reverse.

   Constraints this file holds:
     · zero JavaScript — every page is complete with scripting off.
     · zero third-party requests — fonts are self-hosted (assets/fonts).
       The Datenschutzerklärung (section 3) states this as fact.
     · body text ≥ 7:1 contrast, secondary ≥ 4.5:1 (ratios noted inline).
