Begin from this original fictional-adult illustration. Keep the camera and shoulder line steady. First turn the raised palms gently toward one another. Then the coral-sleeved hand on picture left and the teal-sleeved hand on picture right move inward until those palms meet once near the chest. Keep each wrist connected to its original forearm. After that single visible contact, separate the same palms into a small readable gap and hold. Allow modest elbow adjustment but no full torso turn. Do not exchange an object, grow an extra hand, merge the palms permanently, pass one hand through the other, cut, speak, wave or begin a second clap. This is a visual contact brief only, without a claim of synchronized clap sound or precise timing.
