Build me a clean web app for agricultural procurement centers that helps farmers book a visit, see their slot, and track their procurement status in real time. I want three simple views, one for farmers, one for operators, and one for admins, so each person sees the right dashboard and only the actions they need.

Farmers should be able to register, book a queue slot, get a QR code for check in, and see where they are in line. Operators should be able to scan the QR code, manage arrivals, and update queue and procurement status quickly. Admins should be able to view all bookings, monitor center load, manage slots, and see basic reports or summaries.

Make it feel modern, easy to use on mobile, and clear for people who may not be very technical. Use the existing project setup, connect it to the backend already in the repo if needed, and look up current docs online if you need to.
