 * Anonymous demo — the hub of three adventures, and the sign-in wall.
 *
 * The hub is the first thing an ad click sees, so it borrows the sign-in page's
 * antiquarian-manuscript idiom rather than inventing a second visual language:
 * parchment surface (see pages/sessions.css), Cinzel for display type, Lora
 * italic for prose, and the same brown palette. The wall is different — it
 * appears inside the dark game console, so it is styled for that surface below.

 * The header is kept deliberately short. These cards are 9:16, so they are tall
 * by construction, and on an ad landing page three portraits below the fold are
 * three portraits nobody sees. Everything above them earns its height or goes.
