  "originalPrompt": "Use the uploaded drawing as the first frame. There are exactly two hands and one teal rigid cube. The coral-cuffed hand on frame left is the giver A; the blue-cuffed hand on frame right is the receiver B. Keep both roles, the cuff colors, the cube shape and the camera framing consistent.\n\nShow one slow, continuous handoff. At first A holds the cube and B has a visible gap. B approaches from below and makes contact while A keeps its grip. Next, show a readable shared-contact interval in which B's palm supports the underside and B's fingers form a hold around the visible side. Only after that supporting hold is visible does A open its fingers and withdraw toward frame left. B keeps holding the same cube and settles.\n\nEnd with exactly one cube in B's hand, A clearly separated, and no second handoff. Keep the background and camera still. Do not let the cube float between grips, become a second cube, change size, merge with fingers, fall onto an invented surface or pass through either hand. No text, arrows, extra hands, speech or scene cut.",
