/* =====================================================================
   mixerfirmware.com — BoxCast dark theme (v2)
   ---------------------------------------------------------------------
   Design tokens are the source of truth. The DS-aligned semantic tokens
   (--color-*) carry the official BoxCast dark values; the short legacy
   vars (--bg, --surface, --muted, …) are aliases onto them so existing
   components pick up the palette without per-rule edits.
   Dark values per BoxCast Design System (Remote Mix Black #121419 page /
   brand black #1D1F2A card / bx-grey ramp) + the v2 Claude Design mock.
