  "title": "Watch second hand: request one tick and hold the dial still",
  "description": "Use a clean watch face to practice one small second-hand step while dial indices, hour hand, minute hand and case keep their relationships.",
  "goal": "Describe a single clockwise second-hand tick and a settled ending. This is a visual continuity exercise with original art, not a tested H3 result or a demonstration of timekeeping accuracy.",
  "preparation": [
    "Start from a face-on watch image with separate hour, minute and second hands. The supplied practice dial uses graphic indices rather than tiny wording.",
    "Identify the second hand by its coral color and the other hands by their dark color; do not ask all hands to tell a new time.",
    "Use adjacent minute-track marks as the intended start and stop references. A one-tick request is a visual target, not an exact angular-control setting.",
    "For a real branded dial whose printing must be exact, retain a clean still overlay or use real motion footage; generated text stability is not a reliable preservation workflow."
  ],
  "prompt": "Start with the uploaded face-on watch. The watch case, strap, dial printing and all dial indices remain still. The dark hour and minute hands remain in their starting positions. Only the thin coral second hand makes one small clockwise tick from its starting index to the next adjacent small index, rotating as one straight piece about the center pin. It then holds at that next index for the rest of the shot. Keep its length, color and center connection consistent. Fixed camera, fixed light, no zoom, no sweeping rotation, no repeated ticks, no added numbers.",
  "steps": [
    {
      "title": "Identify the three hands",
      "body": "Confirm that the coral hand can be distinguished from the dark hands at the start. If the hands overlap heavily, choose a clearer start rather than asking the prompt to infer which one should move."

      "body": "Name the next clockwise small index as the ending. Do not combine one tick with continuous time-lapse or a looping clock, which describes a different behavior."

    {
      "title": "Check the center before the tip",
      "body": "Inspect whether the second hand remains attached at the same center pin. Then follow its tip to the neighboring mark; a bending or translating hand is not a rotational tick."

      "title": "Compare the dial after the hold",
      "body": "Compare indices at the top, right and bottom, plus the two dark hands. If print or static hands change, keep the action but simplify the dial source or composite the fixed face in finishing."

  "acceptance": [
    "The watch case and strap keep their shape and position.",
    "The coral second hand remains connected to the center pin.",
    "The second hand moves clockwise toward only the adjacent small index.",
    "The hand remains a single straight element with stable length.",
    "The dark hour and minute hands stay at their starting orientations.",

  "ending": "End on the next small index and keep a settled view long enough to compare the static dial. Record the observed step count; do not label the clip an accurate clock simulation.",
