A fictional adult courier in an amber raincoat starts a small unbranded red delivery scooter beside a steaming noodle stall and pulls away. The camera tracks low beside the rear wheel from a medium-wide view to a medium view. Keep the courier, raincoat, scooter, stall, and camera direction consistent. Use believable acceleration, restrained tire spray, wet neon reflections, and natural cloth motion. Synchronized audio: one engine start, light rain on the awning, tire hiss on wet pavement, and quiet cooking sizzle. No cuts, no extra people entering frame, no dialogue, no readable text, no logos, no products, no advertising, no watermark.",
