Narendra0777R/FaceMark ? reverse-engineered prompt

Build me a simple Python web app called FaceMark that lets me keep track of people by face. I want a clean page where I can add a person, save their details and face image, then use the app to recognize them later and mark them as present. It should have a few basic screens, like a home page, add person page, and a list or dashboard showing who has been marked.

Please wire up the backend, database, templates, and static frontend so the app actually works end to end. If you need to check current docs for any libraries or setup details, feel free to look them up online. Keep the interface simple and easy to use, and make sure the project can run locally without a lot of manual setup.
