+# DANGER: deletes the TimescaleDB data volume (all telemetry data), the
+# MQTT log volume, and the Loki volume. Users/groups/sessions stored in
+# Postgres are deleted with it.
+#
+# Usage:
+#   ./scripts/prune.sh            # containers only
+#   ./scripts/prune.sh --volumes  # also delete all data (destructive)
+#   ./scripts/prune.sh --all      # also remove images and build cache
