  "generationPrompt": "Use case: historical-scene. Create a detailed photorealistic-style maritime reconstruction illustration for Michigan Lake Depths. Input image 1 is a reference render of our newly authored interpretive 3D model of James Davidson, not a historical photograph. Preserve the vessel's distinctive proportions, mast count, deck structures and rig arrangement. Large wooden steam freighter with exactly three bare masts, one aft black funnel, forward wheelhouse and paired tall curved longitudinal timber reinforcing arches on both sides of the central deck. Preserve these arches exactly as dominant features. No deployed sails. Show the entire vessel including every mast tip and bow projection on calm Lake Huron water, in soft natural daylight with a low distant shoreline. Elevated three-quarter side view, generous framing margins, realistic timber/metal/canvas texture and fine working rigging. Retain the same main arrangement as the model while making the scene convincing. No added ships, people, text overlays, logos or watermark. This is interpretive artwork, not documentary evidence. Historical limitation for context: NOAA’s historical account gives 230 ft 6 in × 37 ft and three masts, with reinforcing arches added in 1877. Its vessel page lists smaller surviving wreck dimensions. Photographs guide the silhouette; arch curvature, deck arrangement and paint are interpreted.",
