vanshika4-tech/emergency-hospital-management-system ? reverse-engineered prompt

Build me a full stack emergency hospital management system where patients can register, log in, update their info, and submit emergency requests, and admins can log in separately to see all patients, hospitals, bed availability, and requests. I want a simple React frontend with plain CSS that talks to an Express and MongoDB backend, with secure login using JWT and hashed passwords.

The app should let a patient send an emergency request to a hospital, and let an admin mark requests as resolved and update available beds. Please include seeded demo hospital data and a demo admin account so I can run it right away locally. Keep the UI clean and straightforward, and make sure the frontend reads the API URL from an environment file. If anything depends on current library behavior, look up the latest docs online first.
