+# Waybar custom/failed-units: shows count of failed systemd units across
+# the system bus and the current user's session bus. Hidden when zero.
+# Mako fires only on transition upward (count went up since last check),
+# so transient failures you've already seen don't re-nag.
+#
+# Click handler shows `systemctl --failed` and `systemctl --user --failed`
+# in a floating ghostty.
