/* swarm — the messaging of Beeons, in the Beeons "look beyond" language shared with hive: pure black and white surfaces,
   hairlines, glass pills, round icon buttons, and the brand colours (blue, violet, yellow) only as soft glows.
   Light and dark themes (html[data-theme], set before the first paint by build/theme.js).
   No inline styles anywhere (strict CSP). Overflow rule: every grid/flex child holding text gets min-width: 0;
   names truncate (with a title tooltip), message text wraps anywhere. */
