molvqingtai/WebChat ? reverse-engineered prompt

Build me a browser extension called WebChat that lets people chat with other visitors on the same website.

I want a small ghost icon to appear in the bottom right corner of every page, and when someone clicks it they can join that site’s chat room and start talking right away. The chat should feel anonymous, work across major browsers, and keep messages private by using peer to peer WebRTC so there is no central chat server storing the conversation.

Make it simple and polished, with a clean chat panel, random avatars, and a smooth experience for joining and sending messages. It should feel like each website becomes its own shared room for the people who are already there. If you need current docs or best practices for the browser extension setup, look them up online and use them.
