plexinc/pms-docker ? reverse-engineered prompt

Build me the official Docker setup for Plex Media Server so I can run Plex at home and stream my movies, shows, music, and photos to my devices.

I want it to support the common networking options, host, bridge, and macvlan, with easy to use docker compose templates for each one. Please make the container work with persistent storage for Plex config, transcode files, and my media library, and include the usual setup variables like timezone, claim token, hostname, and the advertised IP when needed.

It should be simple enough that someone can follow the README and get Plex running without a lot of guesswork. If there are any current Plex setup details that matter, look up the latest docs online and make sure the instructions are accurate.
