Divertisseur/Pro-cycling-manager ? reverse-engineered prompt

Build me a simple web app called Pro cycling manager where I can manage a cycling team and keep track of riders in a small database.

I want to be able to add cyclists, view them in a list, and see basic details for each rider like name and any stats the app supports. If there is already some simulation logic, please make it usable from the site so I can run a race simulation or team performance simulation and see the results on screen.

Make it feel like a clean, straightforward admin style app with a home page, a cyclists page, and any other pages that make sense. Keep the data stored locally so it works right away without needing a big setup. If you need to look up anything current while building it, go ahead and check the docs online.

Please wire up the backend, templates, and static files so the whole thing runs smoothly from one start command.
