# Handle camera service around suspend/resume.
#
# v4l2-relayd must be stopped before suspend to avoid GStreamer crashes,
# then restarted after resume once the camera hardware is ready.
#
# The post-resume restart uses systemd-run to avoid blocking the
# password prompt while waiting for the camera to initialize.
