  "title": "Steam above a cup: generate the motion, composite the exact mark",
  "description": "A two-layer cup-shot exercise: a stationary cup with thin steam in the generated clip, plus a separate permitted mark applied and checked in editing.",
  "goal": "Keep the physical cup and the graphic mark in separate production roles. This original method and illustration have not been independently tested; exact lettering is handled in editing rather than promised by the model.",
  "preparation": [
    "Use the supplied blank-cup illustration for practice, or a permitted cup image with the rim, front face and contact shadow visible.",
    "Prepare the exact mark separately. The supplied original FIELD practice mark is a transparent SVG overlay for editing; it is practice artwork, not a customer product logo or an instruction to generate letters.",
    "Choose a composition with empty space above the rim and a mark area below it. Steam crossing the front face makes a clean overlay harder to inspect.",
    "Keep the camera and cup stationary for this exercise. If you need a moving shot, plan tracking or compositing separately and verify it in your editor."
  ],
  "prompt": "Use the uploaded image as the starting frame. Keep the cup, table and camera stationary. A thin soft stream of steam rises from the drink inside the rim, drifting slightly upward and to one side. Keep the steam above the rim; leave the front face of the cup clear. Preserve the cup silhouette, handle position and contact shadow. The steam stays light and does not turn into smoke or cover the scene. Do not add text, a logo, objects or camera movement.",
  "steps": [
    {
      "title": "Start from the clean cup layer",
      "body": "Use the blank practice cup or a source image whose permitted mark you can replace in editing. Check the rim and handle before generating. A stationary camera reduces the number of alignment changes you need to manage later."
    },
    {
      "title": "Give steam a bounded region",
      "body": "Request thin steam above the rim, with the front face clear. Make one small drift the only changing element. Avoid mist filling the room, dramatic smoke or several simultaneous streams on the first attempt."
    },
    {
      "title": "Judge the cup before adding the mark",
      "body": "Inspect the beginning, middle and ending. Confirm that the rim, handle and shadow still match the starting image and that the steam does not erase the front face. Do not use a clean-looking logo as a substitute for these geometry checks."
    },
    {
      "title": "Composite and inspect the exact graphic",
      "body": "Open the accepted clip in your editor. Add the permitted graphic as a separate layer, align it to the cup face and check any required tracking or mask through the clip. Export a short review version and read the mark at normal viewing size, including where steam passes nearby."
    }
  ],
  "acceptance": [
    "The steam begins inside the rim rather than from the handle, table or graphic.",
    "The cup silhouette, rim and handle stay recognisable against the first frame.",
    "The contact shadow and cup base do not move independently.",
    "The steam remains thin and does not become opaque smoke.",
    "The front graphic area remains visible without large steam occlusions.",
    "The composited mark is the intended graphic, with no substituted characters.",
    "The mark remains aligned throughout the edited export; the first frame alone is not enough to pass this check."

  "troubleshooting": [
    {
      "symptom": "Steam grows from the table or cup front",
      "change": "Specify its origin inside the drink, above the rim, and keep the front face clear. Retain the same input so the change can be compared."
    },
    {
      "symptom": "The cup deforms as steam thickens",
      "change": "Reduce the steam request to a thin stream and remove cinematic fog or dramatic smoke. Recheck the handle and rim before attempting a graphic overlay."
    },
    {
      "symptom": "Generated letters change or become unreadable",
      "change": "Do not extend the prompt with increasingly strict spelling instructions. Use the separate permitted graphic layer in editing and judge the exported result."
    },
    {
      "symptom": "The overlay floats away from the cup",
      "change": "Check for cup or camera drift in the underlying clip. Either choose a steadier take or perform appropriate tracking and masking in the editor; the model prompt does not replace compositing alignment."
    }
  ],
  "ending": "End on a stable cup with light steam above the rim. Deliver the input, accepted motion prompt, permitted graphic layer and export checklist together so the next editor knows which layer owns exact lettering.",
  "assetCaption": "Original editable blank-cup illustration for first-frame practice. The separate transparent FIELD SVG is an original editing overlay. Neither asset is a real product photo or a generated-video result."
