rishabh-karmakar/Facial-Recognition-Based-Attendance-System ? reverse-engineered prompt

Build me a facial recognition attendance app in Python that feels like a simple desktop tool for a school or office.

I want a login screen for admin access, and after that a face check before the main menu opens. From the main screen, the user should be able to register a new person using the webcam, save their face data, and then mark attendance automatically when that person shows up on camera. It should keep the attendance records in a local database and also export them to an Excel file so they’re easy to review later.

Please make it use a basic desktop interface, not a web app, and keep it practical and easy to run. If any pretrained face models or setup files are needed, include clear instructions or placeholders for them. It would be great if the app can also show the camera view, recognize faces in real time, and avoid duplicate attendance entries for the same person on the same day.
