  "input": "S01-first-frame.png shows a fictional adult in a rear-side portrait, with a short dark ponytail, a coral tie at the head attachment, a clear outer tip, a teal shoulder line and a pale collar. The whole tail is inside the frame. This is an original stylized illustration, not a photograph of a real person. The three small poses in review-guide.svg are authored phase suggestions, not generated frames or a supplied end frame.",
  "anchors": "Follow three separate landmarks: the tie attached to the head, the ponytail tip, and the collar below. The tie belongs to the moving head; only the shoulders and camera stay fixed. Keeping the tie fixed to the canvas would contradict the requested turn.",
  "originalPrompt": {
    "en": "Start from the supplied original fictional-adult portrait with one short ponytail and a coral hair tie. Keep the camera, shoulder line and collar still. The head makes one small gentle turn toward frame left and then stops. The tie stays connected to the same point on the head and moves with it; do not pin the hair root to the background. The same single ponytail tip follows slightly later, continues a short distance after the head has paused, makes a small settling movement and comes to rest. Keep the entire root and tip visible. Preserve the adult, tie and one continuous tail without splitting the hair into another bundle or detaching it. Do not add wind, a body turn, speech, a hair flip or repeated oscillation. End with the head and the tip both quiet. This is a requested visual sequence, not a measured delay or a physical hair simulation.",
    "zh": "从提供的原创虚构成人肖像开始，保留一束短马尾和珊瑚色发绳。相机、肩线和领口固定。头部只向画面左侧轻缓转动一小段，然后停住。发绳始终连在头部同一位置，并随头移动，不把发根固定在背景上。同一束马尾的末端稍晚跟随，头暂停后，发梢仍继续小幅移动，再轻微收摆并停住。发根和末端始终完整可见。保持同一成人、发绳和连续的一束马尾，不分出第二束，也不脱落。不加风、不转身、不说话、不甩发，不持续循环摆动。结尾头部和发梢都安静停住。这是期望的视觉先后关系，不代表测得了延迟，也不是头发物理仿真。"

      "After a future result exists, locate the interval where the head has stopped but the tip continues a little. Follow the tie during that interval: it must remain attached rather than sliding across the skull.",

      "允许发梢轻微收摆后安静停住。即使末尾外形相似，也不能接受持续往返循环或整束头发脱离。"
