The Red Umbrella at the Rainy Bus Stop

Create a 12-second quiet story at a city bus stop just after rain. A delivery rider in a faded green jacket notices a red umbrella left beneath the bench as an elderly passenger boards a departing bus. Track from the wet pavement to the umbrella, hold as the rider looks between it and the bus, then follow him running only a few steps and passing it through the closing door. Preserve faces, clothing, bus direction, umbrella color, and street layout. End with the rider reflected in the bus window as it leaves. Sound: rain drip, idling engine, door warning, footsteps. No dialogue, heroic slow motion, extra passengers, changing props, text, or watermark.
