The device defaults to an iPhone 15 Pro with a Dynamic Island: portrait platforms are held upright, wide ones sideways, and the cutout turns with them. Hit Change device for the iPhone Duo, notches, punch-holes or iPad — the punch-hole camera is drawn as a bright red dot so you can see what it covers on a dark frame. The shell only affects the four portrait platforms; YouTube and the image cards never had one. Edges and overlays are simplified: they are here to judge composition, not to match a vendor's exact pixels. Switch on Safe area and the clean frame is measured from the real overlays on that screen — inside the frame is clear, the dimmed band outside it is what gets covered.
