Build an event ticketing app named gatestub for a small music venue. FAN - Upcoming shows with poster image, date, doors time and ticket types (general admission, balcony) with prices and quantities. - Buy tickets with email and card, no account. - Get an email with one QR code per ticket. VENUE (accounts: admin and door staff) - Admins create shows and ticket types, and see sales per show. - Door check-in page for phones: scan a ticket's QR code with the camera, or search by name. Shows valid, already checked in, or not found, loud and clear. - Live count of checked in versus sold. Payments by Stripe. Seed one admin, one door account, four upcoming shows with poster images and ticket sales, one show tonight partly checked in. Show the logins on the sign-in page. Tickets remaining and check-in counts update in real time.
