jurihock/bandbase ? reverse-engineered prompt

Build me a web app for a music band that helps us keep everything in one place.

I want to store band contacts, gig details, and music scores, and make it easy to search and update them from a clean browser interface. It should feel practical for real band use, with simple pages for managing people, upcoming shows, set lists, files, and notes, plus a few useful automations so repeated band tasks do not have to be done by hand every time.

Please make it work well in a modern browser, with a polished but simple look, and set it up so it can run reliably in a server environment with a database. If you need to look up current docs online for any library choices, go ahead. Focus on something that is actually usable for a small band, not a demo.
