  constraints:
    anchor: 主视觉即唯一锚点：描边宽度、平涂色板与两级阴影以它为准；可直接沿用为动画上色规范。
    bans:                      # 按优先级，前置到提示词
      - no gradients, no airbrush transitions
      - no brush texture, no grain
      - uniform outline weight only, no tapered strokes
    fail_if:
      - shadow block edges are blurred
      - more than two shadow levels in one area
      - the action is unreadable when scaled down to 20%
    pass: 应能直接交给动画师当作上色参考，不需要再做清理。
