+# Airplane-mode indicator for waybar.
+# Reads the state file the airplane-mode toggle maintains; emits one JSON line
+# (text + tooltip + class) for the custom/airplane module. The file holds
+# key=value lines; only `mode` (on/off) matters here. Anything other than
+# "on" reads as off, so a missing or garbled state file fails safe (airplane
+# mode shown as inactive — i.e. radios assumed on).
+#
+# Laptop-only: airplane mode is meaningless on a desktop, so the module hides
+# itself (emits nothing → waybar drops it) on machines with no battery.
