/* ==========================================================================
   PT Meja Kreasi Sejahtera — UI component layer

   The vanilla equivalent of the shadcn primitives: button, card, field,
   badge, table, dialog, tabs, toast, skeleton, switch, tooltip, plus the
   app shell and the split-flap board.

   Everything here is namespaced .ui-* so it can never collide with the 334
   class names the existing pages and JS already rely on. Those keep their
   names; only their declarations were retokenized.

   Requires tokens.css.

/* ==========================================================================
   Liquid glass material

   Surfaces sample and blur what sits behind them, and carry a specular rim
   along the light-facing edge. Two rules keep it honest:

   1. Only floating chrome gets it — top bar, navigation, cards, dialogs,
      toasts. Never list rows or table cells, where a blur per row costs a
      frame budget nothing else can pay back.
   2. The tint stays dense enough that text on glass keeps the contrast
      ratios the tokens were chosen for. Transparency is a look, not an
      excuse for grey-on-grey.
