Priyansh6747/ClassSync ? reverse-engineered prompt

Build me a class schedule app called ClassSync with three parts working together.

I want a mobile app where students can open it, see their timetable, manage classes, and set a few personal preferences. It should have a clean modern look, with nice gradients, smooth transitions, and a simple way to view today’s classes and full weekly schedule.

I also want an admin dashboard in the browser where someone can edit timetable data, manage metadata, and update the schedule visually. Changes in the dashboard should sync back to the mobile app without needing anything complicated.

Please also build the backend API that stores timetable data in a database, handles basic login security, supports cross origin requests, and can take a PDF timetable and extract the schedule from it. If you need to look up current docs online for React Native, React, or Rust, go ahead. Make it feel polished, usable, and ready to run locally with clear setup.
