+-- ASUS UM5606 Fan State - control-center quick tile.

+-- This tile holds no fan control logic of its own. It mirrors the bar widget
+-- through the plugin's shared state:
+--   reads  noctalia.state "status"  -> { state = ..., available = ... }
+--   writes noctalia.state "command" -> "cycle"

+    [2] = { label = "High-Performance", glyph = "car-fan-2" },
