Frame artwork is unchanged. Its actual transparent screen opening is
x=102, y=100, width=1206, height=2622 in the 1406×2822 image.

The app footage was recorded in a dedicated iPhone 17 Pro Simulator. The 16 Pro
Black Titanium presentation has the same 1206×2622 screen dimensions. iPhone 17
Pro is not offered in black; this is deliberately identified as iPhone 16 Pro.
