   --------------------------------------------------------------------------
   Same language as app.css: 45° chamfers (never rounded), cyan brand streak,
   Space Grotesk for anything structural.

   DESKTOP AND MOBILE ARE NOT THE SAME LAYOUT. This is a full exchange on a
   1240px monitor and a one-handed app on a 380px phone, so:

     - history is a TABLE on desktop and a stacked CARD LIST on mobile,
       not a table squeezed sideways into a scrollbar
     - the invite hub is a 2-column split on desktop, a vertical stack on
       mobile with the QR sized to the thumb
     - the leaderboard podium is three columns wide, and collapses to a
       single highlighted winner with a list beneath on a phone
     - every tap target on mobile is at least 44px

   Motion is real but restrained: things arrive, they do not bounce.
   Everything respects prefers-reduced-motion.
