  recipe:
    identity: 电影分镜转译为铅笔与色粉
    line: 手势驱动的铅笔排线
    color: 去饱和的胶片色域
    lighting: 方向性主光，强明暗对比
    material: 铅笔、色粉、粗纹纸
    texture: 模拟颗粒与纸纹叠加
    character: 写实但被手绘柔化
    atmosphere: 沉静、戏剧性、克制
  negative: [cartoon, flat vector, oversaturated]
  reference_notes: 电影分镜稿 / 黑泽明构图分析
  constraints:
    anchor: 主视觉即唯一锚点：明暗关系与水平线取景以它为准；换主体不换光影结构。
    bans:                      # 按优先级，前置到提示词
      - no hard ink outlines
      - no evenly spaced parallel hatching covering the frame
      - no flat frontal lighting
    fail_if:
      - no clear terminator between the brightest and darkest areas
      - horizontal lines do not dominate the framing
      - pure color blocks beyond the desaturated film range
    pass: 应像分镜稿放大到银幕尺寸仍然成立。
