Galera — Neighbourhood letterpress studio

Galera is the digital experience of a neighbourhood mobile letterpress studio for the amateur printer. Browse the presses (Vandercook, platen, Washington), buy a 7-calendar-day pass, add papers and inks, pay at once and get a real QR pass whose URL opens /pase/:code. Each open studio day stamps attendance (one stamp per civil day, Europe/Madrid). Staff scan the QR at the threshold. The truth layer is the calendar pass + 1 stamp/day + StudioDay capacity: a second overlapping pass is 409 PASS_OVERLAP, a second stamp the same day is 409 ALREADY_CHECKED_IN, and a closed or full studio blocks the door. Galera points are derived from real stamps (10 pts each). There is no 15-minute hold.
