  "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. Vienna, wooden Great Lakes freighter in its photographed earlier THREE-masted career before 1890, 191.4 by 33.8 feet. Exactly THREE bare masts, forward faceted pilothouse, ONE aft black funnel, low covered stern gallery, cargo hatches. Clearing rain over Lake Superior: wet decks subtly gleaming, rain curtain confined to far background, broken gray clouds with pale late-afternoon light. Ship remains clearly visible, moderate lake, no distress, not claimed loss-day weather.",
