vishalkhade25/ClassTaskSpace ? reverse-engineered prompt

Build me a classroom management web app for teachers and students.

Teachers should be able to sign up, verify their email with an OTP, or log in with Google, then create classes with a join code, post assignments with due dates and PDF attachments, view student submissions, give grades, and export submission reports as CSV. Students should be able to join a class with a code, see their assignments, upload or resubmit PDF work, and get marked late if they miss the deadline.

I also want automated email notifications for things like account verification, new assignments, submissions, grades, deadline reminders, and overdue notices. Make it clean, responsive, and easy to use on both desktop and mobile, with separate teacher and student dashboards and protected pages so each role only sees what they should. If you need to look up current docs online, go ahead.
