/* Game-site lobby — "Forge Lobby" aesthetic.
 *
 * Hero band introduces the game; below it, two cards on desktop:
 *   left  → already have Signet (QR + same-device sign-in)
 *   right → don't have Signet (explainer + ranked install CTAs)
 * Cards stack on mobile. Whitelisted/waitlisted states use a single
 * centered card (lobby-card-solo) instead of the two-card grid.
