%description
This git package builds from the tip of the dux-greeter repository.

DMS Greeter is a greetd login screen with the Dux Shell aesthetic.
A single Go binary with the Quickshell UI embedded; the UI is extracted
to the greeter cache directory at startup.

Supports multiple compositors including Niri, Hyprland, Mango, and Sway with
session selection, user authentication, and dynamic theming synced from
Dux Shell.

Conflicts with the stable dms-greeter package; both install /usr/bin/dms-greeter.
Switch explicitly with: dnf swap dms-greeter dms-greeter-git
