linkser34/Travel-and-Tourism-Management-System-MERN ? reverse-engineered prompt

Build me a simple travel and tourism management app where people can browse travel packages, view details, and book a package online. I want a clean homepage, a package booking flow, and a basic admin area where I can add new packages, manage existing ones, and see payment records.

Please make it work as a full MERN app with a separate backend and client, and set it up so it can connect to MongoDB, use login security, and handle payments. Use environment variables for the database, JWT secret, server URL, and payment provider keys. Keep the design simple and easy to use, with a nice modern look for customers and a separate dashboard feel for admins.

If anything is unclear, make sensible choices and look up current docs online if you need to. Make sure the app runs smoothly from local development to production, and include whatever setup is needed so I can start it quickly.
