/* Budapest Rummy — the landing page.
 *
 * The page wears the game's own look: the lobby's deep felt green and gold, the splash art as the
 * hero, the in-game card face (cream, Roboto Bold index, the game's vector pips), the blue felt
 * and wooden rim of the table. Fonts are served from this site (no third-party request: a visit
 * here sends nothing to anyone else, so the privacy policy has nothing to add for it).
 *
 * Motion is decoration only and is switched off under prefers-reduced-motion. Nothing on the page
 * depends on JavaScript to be read: without it the reveals are simply already visible and the
 * table demo shows its last frame.
