m4ousama/110792 — reverse-engineered prompt

Build me a simple working Python web app from this repo. There isn't much documentation, so first inspect what's already in the userpy and webapp folders and keep the existing idea if there is one.

I want to be able to run it locally, open a browser, and see a clean page that proves the app is connected to the Python side. If there are existing user related scripts or pages, wire them up instead of replacing them. Add a basic landing page, simple navigation, helpful empty states, and clear error messages so it feels usable rather than just a blank scaffold.

Make sure the project has an easy start command, any needed dependency file, and short setup notes so someone non technical can clone it and run it. Keep it lightweight and simple, don't add accounts, payments, databases, or big frameworks unless the current code already points that way. Look up current docs online if you need to.
