/* Rock 3 — F&F invite gate (`/:locale/invite`).
 *
 * Mobile-first: card centred in a viewport-filling hero, copy reads
 * "unlock", code field uppercase + tracking. The CSS uses Beacon
 * tokens only — no raw hex / px / colour names.
 *
 * Layout intent: single column, capped at the Beacon shell's
 * mobile-first `.app-main` width via the parent route shell. The
 * `.invite-card` is a paper-on-cloud document tier so the unlock
 * feels considered, not transactional.
