  "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. Sailor Boy, photographed passenger-service career early twentieth century. Compact broad wooden passenger steamer91ft long24ft beam. White hull upper works, TWO passenger levels, open upper gallery around narrow central cabins, forward wheelhouse at upper passenger deck level, ONE black central funnel, flat canopy roof carrying EXACTLY TWO lifeboats aft of funnel, only slim short staffs and no sailing masts. Preserve the wheelhouse height shown in this model; do not add a third house atop it. Soft late-afternoon warm sunlight, gentle blue-green lake ripples, distant hazy wooded Keweenaw shore, a few high clouds. Tiny discreet period-clothed passengers may show scale without obscuring ship; modest coal smoke only.",
