   - Slides in from the right: full width on phones, 440px from 600px up.
   - A plain translucent overlay dims the page (no blur, no glass).
   - Hairline left edge, no shadow.
   - The cart's own layout is at the bottom under .panel--cart.
   - No hover effects anywhere in this file (by design).

   Owner: change the panel width in --panel-w below.
