horizon-client's cpal output and its controllers (gilrs, the DualSense's HID output) move behind the
audio and controllers features, on by default, so the game is unchanged. Built with
--no-default-features it links neither libasound.so.2 nor libudev.so.1. release.yml packages that
build as horizon-engine in horizon-server-linux-x86_64.tar.gz (xtask package-server, checked by
check_imports.py --server); install.sh installs it on Linux (and --archive installs a local one);
horizon-server already prefers horizon-engine. The Dockerfile uses it too, and CI lints it.

- packaging/server/install.sh (Linux, macOS) and install.ps1 (Windows) install the latest release (or
--version) from GitHub, check the SHA-256 GitHub publishes for it, and keep releases side by side:
<dir>/current points at the one in use, so an update or a rollback is one link, and the game files
prepared from the owner's Minecraft stay in <dir>/game-files across updates.
- packaging/server/Dockerfile builds the server and the engine; the prepared game files are mounted
read-only, and the first start writes server.toml from HORIZON_EULA, HORIZON_WORLD, HORIZON_SEED,
HORIZON_PORT, HORIZON_WHITELIST, HORIZON_PLAYERS and HORIZON_OP (`init` reads them too).
- `horizon-server service install|uninstall|print` writes and loads a systemd unit (user, or --system),
a launchd agent, or a Windows task at logon. It runs the installer's launcher, so updates apply on
the next restart.
- Releases build horizon-server and ship it beside horizon-ctl and horizon-prepare; PLAY.txt says how
to run a server.
