/* ============================================================================
   BullionRush.in — "CONSOLE" (Direction C)
   Single stylesheet. Three token layers: primitive → semantic → component.

   The register is a trading console, not an editorial page: no serif anywhere,
   14px base, small type, hairline rules, 3px radii. The hero is a persistent
   strip with the karat switch built into it, not a card. Mobile-first — the
   phone layout is the real design, the desktop grid is the enhancement.

   GLASS BUDGET: backdrop-filter appears exactly twice (hero strip, toast).
   Do not add a third without removing one — it is the main cost on
   mid-range Android. verify.js enforces this.
   ============================================================================ */
