Four variants of the first screen a visitor meets. Tap inside the phone to walk the flow (picker → connecting → scanning → done). All copy is the real in-app catalog; nothing here calls a wallet or a server.
Mockups only — no wallet code, no network calls, no visitor data. Design tokens mirror the live overlay (acid #CCFF3C on glass, Inter + IBM Plex Mono, 22px card, 13px rows).
