minion-7777/NexCast ? reverse-engineered prompt

Build me an internal live video broadcasting app for my organization.

I want a simple web app where people can enter a display name, create a live stream, or join as a viewer and watch streams in real time. There should be a frontend for browsing available streams and a backend that handles login style token creation, stream registration, and room setup for the video service. The video should use a separate LiveKit media server, with the app set up so the frontend talks to the backend, and the backend talks to LiveKit, not the browser.

Please make it work for local development too, with clear environment settings for the frontend, backend, and media server. I’d like it organized so I can run the full stack on my machine, and also deploy the frontend and backend on Windows while the media server runs on an Ubuntu VM. If you need to, look up the current LiveKit docs online so the setup is correct.
