  "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. International, in the later White City excursion-service configuration before 1913. Very broad compact wooden steamer, hull length80.8ft beam26.4ft. Preserve TWO passenger deck levels and the small extra forward raised pilothouse visible in the model, open upper galleries, continuous flat canopy, ONE central black funnel, ONE small boat carried on roof aft and light flagstaffs. Warm white painted superstructure with period dark trim. Calm clear morning, blue-green water with gentle reflections, pale warm sunlight, lightly clouded sky, distant wooded shore. Only subtle funnel smoke. No tall sailing masts. Follow-up correction: remove both flags, including the unsupported Union Jack. Leave the bare staffs and all other ship, weather and scene details unchanged.",
