/* ============================================================
   command-palette.css — refined for a minimal, classy feel.

   Design notes:
   - Layered shadow (ambient + edge + lift) instead of one heavy
     drop shadow — feels lighter, more refined.
   - Backdrop: stronger blur + saturation = frosted-glass without
     visual heaviness.
   - Per-row "COMMAND / FILE / DRAFT" badge is visually hidden
     (sr-only). The group heading + subtitle already communicate
     type; the badge text became redundant noise on every row.
     Grid restructured from 4 to 3 columns to absorb the slot.
   - Typography: titles shed weight (600 → 500) and gain micro
     letter-spacing; small caps headers tighten and shrink.
   - Active-row transition is short and silky.
