Build me a mobile friendly web app for finding and navigating Durga Puja pandals in Kolkata, with an offline first experience so people can use it even when the network is weak or unavailable.

I want it to feel like a simple companion app for visitors, with a clean home screen, a list or map view of nearby pandals, basic details for each place, and a way to see directions or route suggestions. It should work smoothly in the browser and be easy to use on a phone while walking around. If you need current map or location details, look up the latest docs online and make sensible choices.

Please make it polished, fast, and practical, with a modern React based UI, TypeScript, and whatever setup is already in the project. Keep the data and navigation experience focused on Kolkata Durga Puja use cases, and make sure the app still feels useful offline.
