  "title": "单片水果落下：确认一次接触与落点",
  "description": "让一片柑橘短距离下降到盘内，检查数量、首次接触、切片厚度和最后停放位置。",
  "goal": "描述一次低高度食材落下，落盘一次后停稳。原创静图是摆设练习输入，不代表已测试的H3下落效果，也不是冲击物理测量。",
  "preparation": [
    "使用配套单片橙子和空盘，或切片与盘面间隙清楚的授权图片。本任务没有刀具和切割动作。",
    "落点区域保持可见且空置，花盘或水果堆会遮住数量增生和首次接触。",
    "只走短距离向下路线，切面保持可见；大幅翻转会露出隐藏背面，也不便核对瓣纹。",
    "终点设为柔和接触后没有可见回弹。真实食材行为或材质冲击必须准确时使用实拍，不把练习当仿真。"
  ],
  "prompt": "从上传的单片橙子悬在空盘上方的图片开始。摄影机与盘子固定。唯一这片橙子短距离直线下落到盘子空白中央，保持圆形轮廓、果皮厚度和可见瓣纹连贯。切片与盘面发生一次清楚轻柔的接触，然后停在盘内，不弹起，不裂开，不复制。下落时切面大体保持可见。盘子完整，切片不穿过盘面。结尾停留在这一片已经落稳的橙子上。不切割，不新增水果，不溅水，不加文字。",
