  "generationPrompt": "Create a richly detailed realistic maritime reconstruction illustration of Mary M. Scott, a small Great Lakes two-masted canal schooner built in 1857. Follow the attached newly authored 3D model render for silhouette and fittings: 138.6 foot wooden hull, 26.6 foot beam, EXACTLY TWO masts, TWO cream gaff sails and THREE distinct triangular jibs along the bowsprit, modest low aft cabin, cargo hatch covers on deck. The three jibs are important. No funnels or square sails. Sailing on calm blue-green Lake Superior near sandy forested Grand Island, soft early summer sunlight, quiet historical maritime atmosphere. Elevated starboard bow three-quarter view, entire vessel including bowsprit and mast tips comfortably in a landscape frame. Realistic timber grain, tarred standing rigging, sail panel seams and tiny period fittings; no modern equipment. Interpretive reconstruction artwork, not documentary evidence for the uncertain wreck attribution. No text or watermark.",
