   Minimal monochrome, one accent (green = live / online only).

   Shape system (documented, applied everywhere):
     cards & panels 12px | media inside cards 8px | buttons, inputs,
     segmented controls 6px | status badges full pill.
   Implementation note: static bundle, so motion is native CSS +
   IntersectionObserver rather than the Motion library.
