/* ─────────────────────────────────────────────────────────────────────────
   PLACEHOLDER @font-face declarations. OWNED BY @mmg/ui (Wave 1).
   Replace with self-hosted variable fonts (Newsreader serif + Libre Franklin
   sans) per docs/13-design-handoff.md (no Google Fonts at runtime — CWV).
   app.html references this at /styles/fonts.css — keep that href stable.
   Empty on purpose for now; system fallbacks in tokens (--serif/--sans) apply.
