/* ════════════════════════════════════════════════════════════════════
   Bhuchi Arcade — web hub.
   Glassmorphism pass: frosted surfaces over a slow-drifting aurora,
   with motion that reacts to input rather than decorating idly.

   PERFORMANCE NOTE (deliberate, please keep):
   `backdrop-filter` is genuinely expensive — the compositor re-samples
   everything behind the element every frame. It is therefore used only on
   the handful of LARGE, mostly-static surfaces (header, rail, hero,
   sheets, player bar). The 31 game cards use a layered translucent
   gradient that *reads* as glass but costs nothing, because 31
   simultaneously-blurring surfaces drops mid-range phones to single-digit
   frame rates. Same look, a fraction of the cost.

   Breakpoints — mobile-first:
     base      phone      : 2-col grid, pill category row
     >=480px   big phone  : slightly roomier
     >=700px   tablet     : 3-col, search + sort side by side
     >=1080px  desktop    : glass rail + 4-col + side panel by the game
     >=1500px  wide       : 5-col
     >=1900px  ultrawide  : 6-col, capped content width
   Plus landscape-phone and reduced-motion variants.
