Build me a simple healthcare web app where patients can sign up, log in, and book appointments with doctors.

I want a clean, modern interface where users can browse doctors, see basic details like specialty and availability, pick a time, and manage their appointments. Doctors or staff should be able to log in too and view upcoming bookings, update appointment status, and keep track of patient details. Please include a basic dashboard for each role, plus forms for signup, login, booking, and profile updates.

Make it feel like a real product, with good styling, clear navigation, and a responsive layout that works on mobile and desktop. Use whatever full stack setup makes sense for a MERN app, and create the backend, database models, API routes, and frontend pages needed to make it work end to end. If you need to look up current docs online, go ahead.
