   ISM WoW -- design tokens
   Palette: near-black violet ground, vivid purple primary, warm gold as
   the single contrast accent (echoes WoW's own UI gold), soft lavender
   for secondary text. Two type roles: Space Grotesk for display (sharp,
   geometric, a little technical), Inter for body in English, Vazirmatn
   for body in Persian (production should self-host both rather than
   pull from a CDN -- see deployment notes).

   guide, this avoids any dependency on a third-party CDN being reachable
   from inside Iran. Vazirmatn should be self-hosted from day one the same
   way; no @font-face for it is declared here because the OS/browser will
   fall back to its own bundled Vazirmatn-like glyphs only if you've
   already got it installed locally during development -- add the real
   @font-face block once the .woff2 files are in /static/fonts/. */
