/* Edge portals — clickable/swipeable rails linking to sibling apps in the ecosystem
   (FatCatPomodoro now, SquatAlarm later on the left). GPU-accelerated transforms only
   (translate3d, opacity) so this stays smooth on mobile Safari without a carousel library.
   Glass-panel treatment (blur + inset highlight + ambient glow) matches the nav bar's
   backdrop-filter language rather than sitting on top as a flat sticker. */
