# Declarative Sway window manager, status bar, lock, idle and notifications.
# Imported via ./desktop.nix, so only graphical hosts get it.
#
# The compositor binary, PAM and polkit integration come from the system-level
# programs.sway (see ../swaywm.nix); package = null below reuses it instead of
# pulling a second Sway. home-manager owns the user config (~/.config/sway) and
# wires the systemd user session (sway-session.target), which is what lets the
# swayidle/dunst user services start with the desktop.
