金毛 Alfie 日出狂奔（Characters API 一致性） prompt

Style: Cinematic outdoor naturalism, slow-motion-ready, golden-hour grade with cool morning shadows, fine grain.

A wide meadow at sunrise, wet grass beaded with dew, low fog drifting between the blades. The horizon line catches first light, painting the sky pale gold and salmon. Alfie, a buoyant golden retriever, charges across frame from camera right toward camera left.

Cinematography:
- Camera: low-angle tracking shot at knee height, dollying with Alfie
- Lens: 35mm; deep focus to keep meadow and dog sharp
- Lighting: warm rim from rising sun camera left; cool fill from open sky
- Mood: joyful, free, kinetic

Actions:
- Alfie bounds three strides, ears flapping, tongue out
- Splashes through a shallow puddle; droplets arc in slow motion
- A burst of fog parts around his shoulders
- He veers slightly toward camera, eyes bright, then continues past

Background Sound: Paws on wet grass; water spray; soft dawn birdsong. No score.

API: model: sora-2, size 720x1280, seconds 4, characters [{ id: char_alfie }] — name Alfie in the prompt so the model binds the reference identity.
