# PZ rolls its logs into dated directories under Logs/ (logs_YYYY-MM-DD/, plus
# loose YYYY-MM-DD_HH-MM_*.txt at the top) and never removes them. That is not
# something logrotate can bound: it rotates by size, and no individual file here
# ever reaches a sensible threshold -- the growth is in the *number* of files.
# 112 directories and 146k files had accumulated to 18 GB before this existed.
#
# Files are owned by the container's UID, so this runs under podman unshare.
