   ik-fonts.css — THE single self-hosted @font-face layer for the whole IK product.
   Load once per page, BEFORE ik-tokens.css. Replaces the scattered Google Fonts
   CDN <link>s. All faces use font-display:swap. Semantic --font-* tokens live in
   ik-tokens.css (never redeclare font families per-page).

   Retained families (founder decision 2026-07-13):
     Lato            → body + all UI headings (weights 300/400/700/900)
     Bebas Neue      → controlled display only (marketing headlines / promo numbers)
     Playfair Display→ logo / wordmark / approved brand signatures ONLY
     Hind Siliguri   → primary Bengali  ⚠️ NOT YET SELF-HOSTED (see note at bottom)
     Noto Sans Bengali→ Bengali fallback glyph source (subset, unicode-range scoped)
   Retired: Nunito, DM Sans, Baloo 2, Inter (→ Lato). Georgia/Times passages → --font-exam (Arial).
