music-assistant/server ? reverse-engineered prompt

Build me a Music Assistant server that runs on an always on device like a Raspberry Pi, NAS, or mini PC.

It should be a central media library manager that connects to streaming services and to different speakers around the home, so I can browse my music, play it back, and control it from one place. It should work well as a standalone app, but also fit nicely alongside Home Assistant for home automation use. Make sure it can run from a Docker container or in a Home Assistant setup, and include the basic web access so I can manage it locally.

I’d like the project set up so it’s easy to run from source for development too, with clear startup instructions, tests, and a smooth local setup. If you need current setup details or integration docs, look them up online first.
