lazyfetch/locus ? reverse-engineered prompt

Build me a simple full stack app with a Python backend, a frontend, and a small data pipeline that moves data through the system and shows it in the app.

I want the whole thing to feel polished and easy to use, with a clean interface, a backend that serves the data, and a pipeline that can load or process records so the app has something real to display. Please make the frontend show the main data clearly, with a basic way to refresh or update what’s being shown, and make sure the backend and pipeline are wired together cleanly.

If you need to check current docs or best practices while building it, go ahead and look them up online. Also keep the project easy to run locally, with clear setup and sensible defaults.
