shahzaibjillani1/Manzil ? reverse-engineered prompt

Build me a full stack hotel reservation app for Pakistani hospitality called Manzil, with a polished public site where guests can search hotels, filter by city, dates, price, and amenities, then book a room and get a confirmation voucher and email receipt. I also want login and signup with different roles, so guests, hotel owners, and admins each see their own dashboard and tools. Hotel owners should be able to add hotels and rooms, update availability, and manage bookings. Admins should be able to review users, listings, bookings, and basic revenue stats. Make it feel production ready, with a clean modern design, secure authentication, and protection against double bookings when two people try to reserve the same room at once. Include an API with clear endpoints and a Swagger page for testing. Use current best practices and look up anything you need online if the docs are not enough.
