   Shared components for the chat page: avatar, buttons, switcher, pills,
   progress segments, modals, release-notes entries.
   Tokens (colour, radius, motion) come from tokens.css. Nothing here loops:
   motion is one-shot (entrance, hover, press), and tokens.css already stops
   all of it under prefers-reduced-motion.
