jhfckndev/lts-official ? reverse-engineered prompt

Build me a simple full stack web app using the existing backend and frontend folders.

I want a clean, working starter project that someone can open and run without a lot of setup, with the frontend talking to the backend through a basic API. Make it feel polished and usable, not just a blank template. Add a sensible homepage, a few reusable UI parts, and a small set of backend routes that show the app is wired up correctly.

If anything in the repo is unclear, look up current docs online if you need to, and then fill in the gaps with good defaults. Keep the code easy to understand, make sure the app runs smoothly, and set it up so it is easy to extend later. Also add clear setup notes in the project so I know how to start both sides and test that everything works.
