Build me a full stack course learning platform demo called LearnHub with a dark modern UI.

I want students to be able to browse a course catalog, search and filter courses, open course details, enroll and unenroll, see a My Learning page, and track progress through modules by marking lessons complete. Instructors should be able to log in, create and edit their own courses, manage modules, and see simple stats about their courses and students. Admins should have a dashboard where they can view all courses, all users, edit or delete any course, manage modules, and see overall platform stats.

Use a simple login that lets the user pick a role, and auto create new users if needed. Keep the data in memory for now, no database. Make it feel polished and responsive, with role based colors and a clean dark theme. If you need current Angular or ASP.NET Core guidance, look up the latest docs online and follow best practices.
