thanuk-sys/smart-student-portal-mern ? reverse-engineered prompt

Build me a smart student portal for a college that lets admins and students log in and see the right information for them.

I want an admin dashboard where staff can manage student records, marks, subjects, timetables, notices, syllabus files, and other study documents. Admins should be able to add, edit, and delete students, upload PDF files, and keep everything organized in one place. Students should be able to log in and view their profile, attendance, marks, timetable, notices, certificates, and learning materials.

Use a simple modern web app with a separate backend and frontend, and make sure login is secure with sessions or tokens. It should work with MongoDB, and I want demo data seeded so I can open it and try it right away. Keep the UI clean and easy to use, and make sure the app can run locally with one command for the server and one for the client. If you need current setup details, look up the latest docs online.
