/* lobby.css — the deck codex, staged.
 *
 * A character-select stage, not a wall of blocks: a large hero signature
 * card (full face + foil + A/H pill) with the deck's details beside it, a
 * compact codex rail of 17 tabs at the bottom, and a living atmosphere —
 * the card-back artwork drifting behind a vignette, rising embers, and a
 * breathing glow that re-tints to the selected deck's colors.
 *
 * Theming: JS stamps --lobby-a/--lobby-b (the deck's color accents) plus
 * soft rgba variants on #lobby; the halo, glow, eyebrow and Begin button
 * all read them, so switching decks visibly re-themes the screen.
 *
 * Retired (never regress): the old grid of 17 identical 232px blocks and
 * the `.lobby__sig` in-page thumbnail. The hero is a HERO-SCALE showcase
 * (close-up scale, full face), not a thumbnail covering a block.
