txwkx/book-room — reverse-engineered prompt

Build me a simple room booking app for an office. People should be able to register, log in, see a list of meeting rooms, open a room to view its schedule, and book a meeting in an available time slot.

Each user should also have their own timeline so they can see meetings they created or were invited to. When someone is invited to a meeting, they should be able to accept or decline it. Keep the interface clean and easy to understand, more like a small internal tool than a polished enterprise product.

Use a React frontend with a Node and Express backend and MongoDB for storing users, rooms, and bookings. Include some sample rooms so the app works right away in development. Please wire everything up so I can run it locally, create accounts, book rooms, and test accepting or declining meetings. Look up current docs online if you need to.
