Tilt only the same rigid panel a small distance backward at its visible hinge, moving the upper edge slightly away from the camera. Preserve the blank pale inner screen and the four different small corner markers in their original clockwise order. All four inner corners remain visible and move as one plane with straight edges, not a flexible sheet. Keep the hinge connected and do not lift the stand, reveal a new backside, write text, insert UI, add a logo, crop a corner or cut. Stop at a modest new angle and hold one unchanged blank panel. This shot is for later geometry review, not a claim that screen tracking or compositing has been performed.",
