+// Backlight slider, via brightnessctl.
+//
+// This machine drives an external DisplayPort monitor and has no backlight
+// class device at all (brightnessctl only reports keyboard/NIC LEDs), so the
+// row removes itself rather than sitting there as a dead control. Probed once
+// at startup — backlight devices do not appear and disappear.
