vee536/campus-event-mern ? reverse-engineered prompt

Build me a campus events app where students can see upcoming events, check the details, and sign up or register for ones they want to join.

I want a simple full stack app with a clean front end and a backend that stores events and user registrations in a database. There should be a way for admins to add, edit, and delete events, and for users to browse events by date, category, or campus area. It should feel easy to use on desktop and mobile, with a nice home page, event list, event detail page, and a basic dashboard for managing events.

Please set it up in a way that is easy to run locally and easy to expand later. If you need to check current docs or best practices while building it, go ahead and look them up online.
