# usher is launched by LibreWolf via Native Messaging when the extension
# connects. This systemd unit is a watchdog that ensures usher is
# available even before LibreWolf starts, and restarts it if it crashes
# outside of a Native Messaging session.
#
# In typical kiosk operation, LibreWolf manages usher's lifecycle.
# This unit is the step-down supervisor for bare-metal deployments
# where usher must run ahead of the browser for unlock and power
# monitoring.
