shubham-kumar145/Rental-Hub ? reverse-engineered prompt

Build me a full stack vehicle rental marketplace where people can browse vehicles, view details, and book them online, while vendors can sign in and manage their own shop, listings, and bookings.

I want the app to have user registration and login with protected pages, separate customer and vendor flows, and a clean modern interface that works well on mobile too. Users should be able to search or browse vehicles, see pricing and availability, book a vehicle, pay securely, leave a review after their trip, and get confirmation when everything is done. Vendors should be able to create a shop, add and edit vehicles, upload images, and keep track of incoming bookings.

Please include a backend API with secure authentication, database models, payment handling, image upload support, and basic validation and error handling. Use the existing stack in the repo and make the frontend feel polished with good forms, notifications, and a dashboard style experience. If you need current docs for Stripe or Cloudinary, look them up online.
