/* Mobile-first, one-handed. Dark by default; the app is used in a gym.
   Look: near-black glass with a warm ember glow. Cards sit in a hairline "tray"
   (an outer ring drawn with box-shadow, so the DOM stays one div per card).
   The view is rebuilt on every change, so nothing inside it animates on its own —
   the entrance stagger runs from app.js on tab switches only. */
