Corner protectors for iPhone 17 Pro / Max

The 17 Pro generation moved to an aluminium unibody with a raised camera plateau that runs the full width of the back rather than sitting in one corner. That changes the brief for a corner protector: the two upper corners now sit alongside a plateau wall instead of beside open glass, so the upper pieces have less flat rear surface to bond to than they do on a 15 or 16 Pro.

The rails stay flat and the corner radius is consistent with the 16 Pro family, so the seating geometry at the lower two corners is familiar. As with every Pro, the volume pair and the Action button sit high on the left rail and the Camera Control sits low on the right — all four Corners4 pieces wrap the corner itself and are not intended to cross any control.
