developer-yash03/lms ? reverse-engineered prompt

Build me a full stack learning management app called ScholarHub that feels polished for students, instructors, and admins.

Students should be able to browse courses, watch lessons in a clean course player, take quick quizzes at the end of topics, see their progress clearly, save courses to a wishlist, and buy courses securely with Razorpay. Instructors should have a simple studio where they can create courses with modules and topics, add either YouTube videos or uploaded videos, and view earnings with basic analytics for different time ranges. Admins should be able to review courses before they go live and manage users by suspending or promoting them.

Please make it use a React front end and a Node and Express backend with MongoDB, JWT login, email OTP verification, Cloudinary for media, and a good looking modern UI. If you need to check current docs for any integration, go ahead and look them up online.
