# rofi-powermenu (module rofi, novox/hq ADR 0208): lock, suspend, log out, reboot, shut down.
#
# It belongs to the session, and it is the launcher's: its whole face is rofi's. Every action is a
# verb of logind or the service manager, so nothing here names a window manager or a locker:
#   - lock asks logind to lock the session, which the holder of node-lock-screen answers;
#   - log out ends this login session, whichever window manager runs in it.
# Adopted from the workstations' power menu of 2026-10-04 (after adi1090x's powermenu type-2).
