Johni0702/mumble-web ? reverse-engineered prompt

Build me a browser based Mumble client that feels like a normal voice chat app, so people can join a Mumble server from a web page instead of using the desktop client.

I want it to connect through secure web requests for chat and server control, and use WebRTC for voice by default, with a fallback that still works when WebRTC is not available. It should let someone enter the server address, port, and username, then connect, talk, and see the channel and chat information in a clean interface. Add a light theme and a dark theme, and make it easy to switch themes from the URL.

Keep it focused on the core client experience, since some admin features are not needed yet. Also make it possible to configure defaults after build if needed, and if you need to check anything about the current browser APIs or Mumble setup, look up the latest docs online.
