# Reports the MANUAL-INHIBIT input for the Eww caffeine widget: whether a manual
# caffeine toggle currently holds the shared idle lock.
#
# The lock is shared with presence-detect.sh, so "PID alive" alone can't tell the
# two sources apart. OWNED_FLAG is present only while the daemon owns the lock, so
# "PID alive AND OWNED_FLAG absent" uniquely means a manual caffeine session holds
# it. (For the PRESENCE input — camera sees you — see presence-status.sh.)
#
# Prints "true" for a manual caffeine session, else "false".
