    anchor: 主视觉即唯一锚点：柔光软硬、中性色板与负空间比例以它为准；换产品不换打光方案。
    bans:                      # 按优先级，前置到提示词
      - no hard shadows, no sharp specular highlights
      - no second object in the scene
      - no surface texture, no pattern
    fail_if:
      - the shadow edge is clearly readable
      - the object occupies more than one third of the frame
      - a second accent color appears
    pass: 应像一本品牌手册里的产品页，克制到没有一句废话。
