Ahanmr/U-Store-Amazon-Go- — reverse-engineered prompt

Build me a simple Amazon Go style demo in Python with a small Flask web app. I want a flow where I can add a customer by capturing face images, train the face recognition model, and then use a live camera view to recognize that person when they come back. Please connect it to a basic database so the app can save customer details and show the recognized name on screen.

If there are already pieces for product or object recognition in this project, wire them in as a simple demo too, but the main goal is getting the face dataset, training, and recognition flow working end to end in the browser. Make it easy to run locally, with clear pages for enrolling a person, starting training, and opening live recognition. Keep the setup and instructions simple, use the existing project files as much as possible, and look up current docs online if you need to.
