## Step A: Scene Breakdown（场景拆解）

写分镜前必须先完成场景拆解。详细规范见 `storyboard-rules.md` Scene Breakdown 章节。

- **Subject**: 产品的可见特征（材质/颜色/形态/关键细节），在画面中的状态
- **Environment**: 空间布局，背景元素，地面/墙面/材质
- **Lighting**: 光源方向 & 质感（硬/软），暗示的时间段
- **Visual Anchors**: 3-6 个必须在所有面板中保持一致的要素（色调、主光源、天气/雾/雨、颗粒/质感、背景标记物、产品外观）

## Step B: Cinematic Approach（电影手法）

详细焦距/DoF/镜头运动规范见 `storyboard-rules.md` Cinematic Approach 章节。

- Shot progression: 如何从全景推到特写服务于情绪节拍
- Lens range: 焦距范围（18-85mm），DoF 倾向
- Light & color: 对比度，主色调，材质渲染优先级

## Step C: 9-Frame Keyframes

每帧是一段 **80-120 词的英文 Image Prompt**。格式规范见 `storyboard-rules.md` Keyframe Format 章节。
