alexmsza/GestorFrota ? reverse-engineered prompt

Build me a full stack fleet and vehicle rental management app with a clean modern interface and a secure backend.

I want to be able to log in and register users, then manage vehicles, drivers, and rental contracts from a dashboard. Vehicles should have statuses like available, rented, and maintenance, and drivers should store their license and document details. Rentals need to check for conflicts so the same vehicle or driver can’t be booked for the same dates, and the app should calculate the rental value automatically. Please include role based access so managers can create, edit, and delete everything, while regular operators can only view data.

Make the frontend responsive and polished, with light and dark mode. Expose a documented API with Swagger, and use token based authentication. If you need to, look up current docs online to keep the setup aligned with the latest versions.
