+# Boots a pixel_6 AVD on the same AOSP API-35 image the e2e tier uses -
+# natively 1080x2400, the geometry the tracked PNGs already have - and
+# screencaps Main and Settings into
+# fastlane/metadata/android/en-US/images/phoneScreenshots/.
+#
+# The AVD is its own (scrcpy-shots, not scrcpy-test) so a screenshot run
+# never perturbs the device state ./test e2e asserts against. Panel size
+# comes from the device profile rather than `wm size`: overriding
+# geometry on a booted software-GPU emulator ANRs SystemUI, and the ANR
+# dialog lands in the capture.
+#
+# Runs inside the test image; orchestrated by ../test.
