yashwardhan-chaudhari/FlashAds ? reverse-engineered prompt

Build me a web app called FlashAds for finding, pricing, and booking outdoor and digital advertising boards in Pune.

It should feel like a simple two sided marketplace, where businesses can browse ad spaces like hoardings, unipoles, LED screens, and bus shelters, see them on a map, check dates and availability, and book the ones they want. I also want an owner side where people can list their boards, add photos, location, size, type, pricing, and manage bookings. Please include login and signup, a clean modern UI, and a smooth flow from search to booking to confirmation.

Use the tech that fits this project, and set up both the frontend and backend so the app can actually run. If you need to check current docs for React, Vite, or any libraries, feel free to look them up online. Focus on making it feel polished and easy to use, with INR pricing and a layout that works well for both buyers and owners.
