  "generationPrompt": "Create one detailed, photorealistic museum-quality maritime reconstruction illustration, landscape 3:2, using the attached newly authored 3D model render as the principal vessel shape reference. Show the entire original working ship afloat on Lake Superior, three-quarter view, realistic period construction, restrained natural colors, distant undeveloped forested shoreline. Preserve the number of masts, funnels and major superstructures shown in the reference; water hides the underwater hull. No captions, labels, modern buildings or ships. This is interpretive historical artwork, not documentary proof. W.S. Crosthwaite, interpreted earlier 1870s–1880s sailing career, three-masted wooden Great Lakes cargo schooner 198 by 35 feet. Exactly THREE sailing masts, three gaff sails and two triangular headsails as reference, bowsprit, low aft cabin, no funnel or steam machinery. Sailing gently under cream canvas, fair bright afternoon with small cumulus clouds, emerald-blue lake, subtle warm light on wood and linen. This predates conversion to a tow barge.",
