/* ---------- Webfont declarations ----------
   Century Gothic and Segoe UI Symbol are system fonts that ship
   with macOS / Windows. Where unavailable we fall back to the
   nearest Google Font matches:
     Century Gothic     → Questrial / Jost (geometric, humanist)
     Segoe UI Symbol    → "Segoe UI", system-ui, then Inter
     RODE Noto Sans Hindi R → Noto Sans (regular)
   See README → "Type & Font substitutions" for details.
