kaya0s/TeachTrack ? reverse-engineered prompt

Build me a classroom behavior tracking system called TeachTrack.

I want a teacher app where someone can start a class session, use the camera to monitor student engagement in real time, and see simple live feedback like engagement scores, alerts, and a session summary at the end. The score should feel fair even if the camera cannot see every student, so only the students actually detected should count toward the live engagement math.

Also build an admin area where a school staff member can manage colleges, majors, subjects, teachers, and system settings, plus view things like logs and backups. Add a backend API for login, classroom data, session tracking, and saving the analysis results in a database.

If it helps, use current docs online for anything you need to confirm. I also want the project organized so the teacher app, admin portal, backend, and documentation site each work as separate parts of the same system.
