/* ============================================================
   Overlay shared shell
   Applies a single coherent modal language across cart, checkout,
   profile, orders, and admin overlays. Loaded AFTER each
   *-overlay.css so source-order wins resolve in this file's
   favor — no per-overlay edits required.

   Design direction (sets these overlays apart from the page):
   - Atmospheric scrim: deep navy vignette with heavy backdrop blur
     + saturate, so the page behind feels behind frosted glass.
   - Lifted modal: three-layer shadow (outer halo + closer cast +
     1px outline ring) plus an inner top highlight to simulate
     light catching a real surface edge.
   - Quiet white header: drops the old navy gradient bands. Replaces
     with eyebrow-style hairline divider so each overlay feels like
     an extension of the marketing surfaces, not a different app.
   - Cinematic entry: 480ms ease-out scale + translate. Slow enough
     to feel intentional, fast enough not to drag.
