A step-by-step walkthrough for running the host on Bazzite (the immutable
Fedora-Atomic gaming distro): the two install paths (rpm-ostree layering vs the
bootc image), udev + the `input` group, host.env knobs (gamescope-default), the
systemd --user service, firewall ports, verification, and troubleshooting — all
grounded in the packaging/ files. Flags the operator-run COPR, the loopback-only
mgmt port, and that the bundled unit runs the GameStream `serve` host (not m3-host).
