Use Reference Video 1 only for the start-and-pull-away action, natural weight shift, low side-tracking camera path, wet-road tire spray, and action timing; do not copy its amber-coated rider, red scooter, noodle stall, or night-market layout. Use Reference Audio 1 only for the engine-start cue, rain intensity, tire hiss, and timing; do not add music. Create one continuous four-second shot under the covered flower-market arcade shown by the reference identity: the courier mounts the blue cargo tricycle, starts it, and pulls forward past the flower buckets while preserving the referenced face, clothing, vehicle, roof, and wet-stone setting. No cuts, no extra people, no dialogue, no readable text, no logos, no products, no advertising, no watermark.",
