/**
 * Plan 9 Task 6: the self-contained "book a table in a room that does not
 * exist" demo, moved from the Worker (public/assets/marketing/marketing.css)
 * and restyled with this site's own brand tokens instead of the copied
 * `--bb-*` values guest.css lent the Worker's page.
 *
 * Every colour below is `var(--color-…)` — no literal — per the brand guard
 * (tests/template/brand.test.ts) and the vetted pairs in
 * tests/unit/contrast.test.ts: available tables pair `--color-bg` text on an
 * `--color-accent` fill ("bg text on accent button"), held tables pair
 * `--color-text` on `--color-surface` ("text on surface"), and the muted
 * states (booked, too-small) pair `--color-muted` on `--color-bg` /
 * `--color-surface` ("muted on bg" / "muted on surface") — all four are
 * asserted ≥ 4.5:1 there. A genuinely non-brand literal would need a
 * "brand-guard-allow" comment marker (see tests/template/brand.test.ts);
 * none was needed.
 *
 * The demo sits on the cream #demo section (`.surface-cream`, global.css), so
 * its own surface reads as a "device" on the page rather than a pane of the
 * cream section itself: charcoal (--color-bg) with cream text (--color-text),
 * like a phone on a table.
 *
 * Every class name below is demo.js's own — copied byte-for-byte from the
 * Worker — so this file styles them without demo.js needing any selector
 * change to move here.
