waqaasahmed2345-art/eventify-scanTicket ? reverse-engineered prompt

Build me a full event booking app where people can browse events, book tickets, and get a QR code ticket they can show at the door.

I want a web app for users and admins, plus a mobile app for organizers or staff to scan tickets and verify entry. The organizer side should be able to create and manage events, see bookings, and scan QR codes to mark tickets as used. The user side should let people sign up, log in, view event details, book tickets, and see their booked tickets in one place.

Please set it up as a full stack MERN project with a clean modern UI, and make the web and mobile parts work together with the same backend. If you need to look up current docs online for anything, go ahead. Include sensible auth, basic validation, and a simple dashboard so the app feels like a real product.
