+
+    This test verifies that when:
+    - CONF_SLEEP_BRIGHTNESS: 0 (brightness set to 0%)
+    - CONF_SEPARATE_TURN_ON_COMMANDS: True (split brightness and color commands)
+    - Sleep mode is active
+
+    Attempting to turn on a light results in the light staying OFF because:
+    1. With separate_turn_on_commands=True, the first command sets brightness=0
+    2. Setting brightness to 0 is equivalent to turning the light off
+    3. The second command (color) is then skipped because the light is off
+
+    This documents the edge case behavior where sleep_brightness=0 effectively
+    prevents lights from turning on when using separate turn-on commands.
