What changed

NFC cards at every table: a phone tap, no app and no typed URL.
Private-first routing, so unhappy guests reached the manager rather than Google.
AI-drafted replies to every review, positive and negative, approved by the location.
Per-server attribution, showing which staff generated five-star visits.
