 # OPERATION NOTES:
 # - Flash this to the ESP32-P4 side of the board.
 # - This version is intended to confirm:
-#   - ESPHome remains stable during display initialisation
+#   - MIPI-DSI display remains stable
-#   - MIPI-DSI display initialises correctly
+#   - Display test text is rendered
-#   - Backlight control remains available in Home Assistant
+#   - Backlight brightness remains adjustable from Home Assistant
-#   - Basic text is rendered on the screen
+#   - GT911 touchscreen initialises

-# - Portrait rotation will be configured after the display and touch are proven stable.
+# - Display remains in native landscape orientation for this test.
+# - Touch the screen at several locations and inspect the logs.
+# - Expected coordinate range is approximately:
+#   - X: 0 to 1023
+#   - Y: 0 to 599
+# - Portrait rotation and LVGL will be added after touch is confirmed.
 # - This version intentionally does not yet configure:
 #   - Ethernet
-#   - Touchscreen
 #   - LVGL
 #   - Ambient light sensor
