Build me a full stack movie booking app called Movie Marketplace.

I want viewers to be able to browse movies, see theatre showtimes, pick seats from an interactive seat map, book tickets, view their orders and receipts, and cancel bookings with refunds. I also need a theatre staff area where staff can manage their theatre, schedule shows, set seat prices for VIP, Premium, and Standard, and check in guests. On top of that, build an admin area for managing users, movies, theatres, shows, bookings, reports, and settings.

Please make login role aware, with separate access for Viewer, Theatre Staff, and Administrator, and block people from seeing pages they should not access. Use a clean modern dashboard style, responsive layout, notifications, and some simple charts for booking and revenue stats.

Set it up as a working MERN app with a React frontend, Node and Express backend, MongoDB data, JWT login, and a seeded demo database with test accounts so I can try it right away. If you need to look up current docs online, go ahead.
