Build me a simple student portal app that lets a user sign up, log in, and then manage their school info in one place.

I want a clean dashboard where students can see their profile, academic details, and a study planner. It should also have a few simple pages for things like registration, dashboard, and planner, with a nice modern UI that works well on desktop and mobile.

Please make it feel like a real usable app, not just a demo. Store and load the student data properly, and include a couple of basic example records so it’s easy to test. If you need to check current docs for anything, feel free to look them up online. Keep the code organized and make sure the main flows work end to end.
