/* /demo only (src/http/demo.js). Loaded after /site.css and /connect.css and uses their tokens
   (--bg --panel --ink --muted --line --brand --accent --teal), so light and dark follow them. The
   chips mirror the webmail's (/console.css .chip). No inline styles: the page CSP is style-src
   'self'. Panels stack on phones. Motion is opacity/transform only and off under reduced motion. */
