/* Simple chat kit (docs/architecture/simple-chat.md). Companion of /shared/ui/js/simple-chat.js.
   One plain text screen: a slim header, the conversation above, the box pinned at the bottom. It paints only with the
   framework theme tokens (surface-themes.css + the saved cockpit theme); the fallback after each token keeps the page
   legible when a theme or a host (the OSHAL Node window) omits one. A host may also set --sc-on-accent, the text
   colour on the accent-filled "you" bubbles and Send button. */
