/* The public demo's banner. Loaded only when DEMO_MODE is on — the server adds
   the <link> to the page on the way out — so a real install never ships it.

   Self-contained on purpose: the guide is dark and branded, the builder is light,
   and the banner has to read the same on both without borrowing either one's
   variables. Not fixed to the viewport: on a phone, a strip that follows the
   reader covers the very steps they came to look at. */
