Use the supplied original perforated-sheet illustration. Fixed front camera and fixed left clamps. Pull the existing narrow right tab gently to the right. Continue the short starter split downward along the already visible perforation line: the next intact bridge separates at the advancing tear front, followed by the next. Keep the broad left sheet in place. Let the two new edges open behind that front while material ahead remains connected until reached. Finish with exactly two paper pieces and the original perforation route visible on their facing edges. No scissors, adhesive backing, third strip, confetti, crossfade or instant full-length cut. Keep the tab recognizable and all separation inside the frame.
