  "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 Harvey Bissell, not a historical photograph. Preserve the vessel's distinctive proportions, mast count, deck structures and rig arrangement. Later wooden lumber schooner barge with exactly two bare masts, furled gaff rig and deck-stacked sawn lumber, low aft cabin. No third mast, funnel, deployed sails or propulsion. 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: Depicts the photographed two-masted towing barge, after earlier barkentine and three-masted schooner phases. The two masts and lumber load follow historical images. The exact conversion date, cargo quantity, deck fittings, paint and underwater hull are uncertain.",
