/* 2026-06-04 design-sweep pass: this file used broken Tailwind token
   classes (bg-bg-*, text-text-*, border-border, bg-accent-ember,
   focus:ring-accent-ember) throughout — none of those are defined in
   tailwind.config.js, so the browser pane rendered as transparent
   nothingness. Sweep replaces them with inline style={{ ... CSS
   vars ... }}, the SearchBar primitive for the card search input,
   and `glass-panel` + `rounded-2xl` on the outer pane to match the
   Liquid Glass system. Rarity badge colours were converted from the
   stale orange/yellow/gray/green Tailwind defaults to a neutral
   inline pair (bg-tertiary surface + ember/text-primary fg) so they
   render correctly in dark theme. */
