SHOEBILL04/MELA ? reverse-engineered prompt

Build me a web app for managing a big cultural fair, where an admin can create a new fair, set the stall prices and ticket prices, and the system automatically sets up the fair days and available stalls behind the scenes.

Vendors should be able to log in, browse active and upcoming fairs, see which stalls are still open, and reserve one or many stalls in a single checkout without double booking. Visitors should be able to see upcoming fairs by date, check ticket availability for each day, and buy tickets for a group.

I also want a simple jobs area where people can see vendor job openings at active fairs and apply directly. Make it look clean and modern with a nice dashboard feel, and use a database driven approach so the important booking and validation logic is handled safely on the backend. If you need to look up current docs online while building it, go ahead.
