Sora提示词：15-second comedic street scene

15-second comedic street scene, bright sunny day, young man @wanyewong.citystride (casual hoodie, jeans, neutral face) walking casually. Fast-paced sequence with seamless cuts:
1. (Close-up, overhead) Bird flies above → droppings fall → he raises umbrella, droppings miss.
2. (Medium shot, side view) Sprinkler truck sprays water → he steps left, water misses.
3. (Overhead, slow-mo) Potted plant falls from balcony → he ducks, plant hits ground.
4. (Low angle) Shopping cart rolls toward him → he turns smoothly, cart passes.
5. (Dynamic shot) Food box flies from bicycle → he jumps, box misses.
6. (Close-up, playful) Balloon floats toward face → he waves hand, balloon drifts away.
Ending: He stops, smiles warmly, text overlay: "Small wins, big smiles!"
Style: Bright colors, upbeat piano music (like 'Happy' instrumental), no dialogue, natural movements.
