/* Self-hosted fonts (spec §3.1): local woff2 only — Cinzel 700/800 and
   Hind Siliguri 400/700, Latin + Bengali subsets. Google Fonts CDN is
   blocked by our CSP (font-src 'self'), so the files live in /fonts/ and
   are served same-origin. The @font-face rules below only *declare* the
   faces; the browser downloads each subset on demand by unicode-range.
   The same six files are preloaded via FontFace in engine/text3d.js
   (loadFonts) before any 3D text texture is drawn. Fallbacks are the
   system stacks in --font-bn / --font-display below. */
