/* F3: the one chat component (agents/chat-app.js), drawn from the base system's ChatApp

   --sp-* spacing, --r-sm radius (console.css's, with the 6px the design draws as its fallback). The values, light
   and dark, come from assets/base.css; nothing here names a colour, so dark follows the host's data-theme.
