rohan-bahule/doctor-appointment-booking-system ? reverse-engineered prompt

Build me a doctor appointment booking app that feels polished and easy to use for patients, doctors, and an admin.

Patients should be able to sign up, browse doctors, see available time slots, book and pay for appointments, get reminders, cancel if needed, and leave feedback after the visit. Doctors should have their own dashboard where they can set working hours, lunch breaks, block time off, view appointments, and see ratings and earnings. Admin should be able to manage doctors, invite new ones, monitor bookings, and handle cancellations and refunds.

I want the booking system to avoid double bookings, and I want payments to be handled safely with proper confirmation before a booking is finalized. Please also include login and role based access so people only see what they should. Make the interface clean and modern, and if you need to check current setup details or docs online, do that.
