  "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 H. Hall, not a historical photograph. Preserve the vessel's distinctive proportions, mast count, deck structures and rig arrangement. Compact wooden cargo schooner with exactly two masts, two gaff sails, two triangular topsails above them and three headsails on the long bowsprit, low aft cabin. Light upper hull. No funnel or third mast. 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: The historical image on NOAA’s page clearly shows two masts with gaff sails and topsails; its text instead labels three masts. This model follows the image, not a proven loss-day configuration. Seven display sails, hull lines, deck layout and paint are interpretations.",
