Ultra-realistic smartphone vertical video. Hood open on a parked car. An American man leans over the engine bay and taps a loose plastic engine cover— the cover rattles loudly and visibly shifts because a retainer clip is missing. Close-up: the loose corner lifting up and shaking with engine vibration. Natural daylight, handheld camera, no product shown yet, no flicker. After the problem is shown clearly, cut to the exact 3-layer transparent 820PCS automotive retainer clip kit from the reference image—perfectly accurate shape, color, compartments, no deformation.
