  "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. Charles H. Bradley, wooden steam lumber carrier, approximately 201 ft long and 37 ft wide, photographed working career early twentieth century. Raised three-tier forward accommodation and high wheelhouse, one tall foremast, a lighter aft pole staff, ONE tall black funnel aft, low stern house, extensive squared timber cargo stacks amidships. Keep the long low working hull and its spacious cargo deck. Breezy gray overcast afternoon, textured slate-green lake with modest small whitecaps and distant cloud layers; muted filtered sun reveals the lumber. A little thin coal smoke from the aft funnel only. No canvas on the masts.",
