Build out this app so it actually works from end to end.

I want a simple project with a frontend and a backend that connect cleanly, and I want the whole thing to run without errors. Please make sure the main user flow works, the pages load properly, and any existing tests pass or get updated if they are broken. If something is unclear from the current files, inspect the code, fill in the missing pieces, and keep the structure tidy so it’s easy to understand later.

If you need to check current docs or best practices online for anything in the stack, go ahead and do that. After you finish, make sure the app is in a good state and leave it ready to use.
