samdeupta/uvic-prereqmap ? reverse-engineered prompt

Build me a simple web app for UVic PrereqMap that lets a student search for a course and see its prerequisites in a clear visual way.

The backend and course data already exist, so focus on creating the missing front end and wiring it up to the existing API. I want a clean page where I can type a course code or browse by subject, click a course, and see its prerequisite structure shown as an easy to understand graph or tree. It should handle cases like choose any one of these courses, or complete all of these, without making the user read a wall of text.

Please make it feel polished and easy to use, with a simple layout, loading and empty states, and readable course details. If you need to check the API docs or current best practices, look them up online. Also update anything needed so the app runs smoothly with the existing Docker setup.
