      "generationPrompt": "Create one detailed, realistic maritime reconstruction illustration for Michigan Lake Depths. Use the provided newly authored 3D model as the primary shape reference: preserve the vessel's hull proportions, mast count, funnel count and positions, cabin heights, deck organization and lifeboats. Show the complete ship afloat at its plausible working waterline, in a natural three-quarter view with ample framing and a Lake Superior / Keweenaw wooded shoreline far in the background. Premium museum interpretive maritime illustration, believable materials, subtle weathering, finely resolved rigging and timber. This is artistic reconstruction, not a historical photograph or exact archaeological record. No text overlay, border, logo, modern vessel, modern skyline or extra funnels. Weather and shoreline are artistic choices, not a portrayal of documented loss conditions. No deployed sails, damage, sinking, fire, dramatic peril or ocean-sized waves. Lizzie A. Law in the specifically selected 1907 towbarge appearance. Long wooden schooner barge196.1ft hull length33.9ft beam, EXACTLY TWO widely separated retained masts, original middle mast REMOVED, original bowsprit REMOVED. No funnel, engine smoke or deployed sails. Low small stern cabin, broad expanse of squared lumber stacks on a long low cargo deck. Fine standing rigging and stowed canvas/booms allowed. Floating quietly while waiting for a tow, no self-propelled wake. Fair early afternoon, light scattered clouds, softly rippled deep blue water and distant green shore. Keep long deck and widely spaced masts exactly like model; remove any apparent thin projecting bow line rather than turning it into a bowsprit."

  "generationPrompt": "Edit the supplied AI interpretive ship illustration with a narrow correction. Replace the metallic rusty plated appearance of the hull with painted timber: light grey upper band and dark brown lower wooden planking, subtle horizontal seams, grey weathering only. Remove all orange rust streaks, plate patches and rivet-grid effects. Preserve two bare masts, low aft cabin and lumber load exactly. Preserve framing, aspect ratio, lighting and all unmentioned details. Keep deck winches as squat transverse rope drums with solid flanges, never barrels. No text, no lettering, no name boards, no guns, no weapons, no cannon, no watermark. No extra masts or floating parts. Do not add modern equipment. This remains an interpretive illustration, not historical photographic evidence.",
