singhaadarsh1/Skillio--Learn-Sell-Courses ? reverse-engineered prompt

Build me a full stack online learning platform called Skillio where people can sign up, log in, browse courses, enroll in them, and track their progress in a personal dashboard.

I want learners to be able to view course details, see lessons, and mark lessons as completed. They should also have a profile page where they can see their account info and change their password. Admin users need a separate protected dashboard where they can add new courses, edit existing ones, and delete courses they manage.

Use a modern, clean interface with responsive pages for home, course listings, course details, sign in and sign up, learner dashboard, profile, and admin dashboard. Protect the right pages so only signed in users or admins can access them. Store the data in MongoDB and use JWT based auth with role based access control. Please make the app feel polished and working end to end, and look up current docs online if you need to.
