  "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 Lucinda Van Valkenburg, not a historical photograph. Preserve the vessel's distinctive proportions, mast count, deck structures and rig arrangement. Qualified three-masted wooden cargo schooner interpretation, exactly three masts with three gaff sails and two triangular headsails, a broad full stern and low aft cabin. No funnel, square sails or modern features. 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 2020 information sheet calls this a three-masted schooner; its vessel page says two. This model selects three and leaves the conflict unresolved. Wreck imagery guides the centerboard trunk and full stern; sail inventory, hull lines, deck fittings and paint are interpreted.",
