Build me a simple web app that lets people send files and clipboard text directly between devices on the same WiFi network, kind of like AirDrop or LocalSend.

It should automatically find nearby devices, let you pick one, and transfer large files securely without needing an account or any central server. Make it work as a progressive web app so it can be opened in a browser, installed on a phone or desktop, and hosted on static hosting or run locally. If possible, use the browser’s built in secure peer to peer connection so the transfer stays private.

I want the experience to be very easy, just open it on two devices, see them discover each other, then share files or paste text. If you need to check current docs or best practices for browser file sharing, go ahead and look them up online.
