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。
