# ~/.config/nomarchy/current/theme/waybar.css that theme-switch rewrites)
# without destroying its layer-shell surface. A full systemctl restart
# tears the surface down and creates a new one back-to-back, leaving a
# frame or two where Hyprland hasn't cleared the dead surface yet — that's
# the "old on top of new with artifacts" you see after a theme switch on
# the live ISO.

# non-zero when the unit doesn't exist; `list-unit-files` does not.
