Start from the original smooth bowed-strip illustration. Fix both dark endpoint pins and the camera. Move the pale pad straight downward against the coral-marked crown. Let the same connected teal strip flatten and pass through the line between its fixed endpoints into a downward bow, without adding a hinge, tear or extra strip. Then lift the pad clear. Keep the strip in the opposite downward-bowed pose after the pad withdraws, with the coral dot still on its original midpoint region and both endpoints attached. No moving supports, permanent pad contact, accordion folds, camera zoom or cut between poses. Show one press-and-withdraw sequence. This is a proposed visual snap-through, not a verified prediction of spring behavior.
