   library-search.css — modal + result-card styles for
   js/kiosk-library-search.js. Glass aesthetic matches the bilateral
   listening overlay (bilateral-glass.css) for visual consistency
   across the kiosk's modal surfaces.

   Loaded by kiosk.html. Self-contained — no CSS variable deps from
   kiosk.css beyond the system tap-target constants from
   mobile-tokens.css (--tap-target-min, --input-min-fs).
