+# scripts/test-gfx.sh — automated graphics-layer verification.
+#
+# The cursor overlay compositor is the core of the GUI path: the shadow
+# holds true content, the display gets shadow pushes with the cursor
+# painted on top at every push, and the cursor never enters the shadow.
+# This test boots QEMU headless and runs `gfx check` — an in-kernel
+# pixel self-test that reads back shadow *and* display pixels — plus the
+# `gfx` demo scene.  Cursor *movement* against injected mouse input is
+# covered by test-mouse.sh; here we prove the compositor math.
+#
+# Usage: ./scripts/test-gfx.sh
+# Env:   OVMF, QEMU (same defaults as other test scripts)
+#
