  "generationPrompt": "Goshawk in photographed post1904 two-mast wooden towbarge form. Black painted hull with thin pale sheer stripe and white bow bulwark; tall foremast and shorter aftermast; small raised aft steering shelter on low cabin, lumber stacks, sturdy bow bitts, no bowsprit, no funnel, no deployed sails. Calmly moored Tawas Bay, natural tan manila bow line reaching mooring outside frame, no wake. Low SANDY shore with grasses and distant trees, distant rain squall and warm sidelight. The model controls geometry, the second reference is its own historical photograph supporting silhouette. Create a detailed historically interpretive lake scene faithfully matching the supplied revised GLB render, same three-quarter view, complete hull and all mastheads inside landscape frame. Preserve vessel proportions, exact mast/funnel count, cabin arrangement and fittings. Museum reconstruction illustration, physically plausible lighting and materials. No text, no lettering, no name boards, no guns, no weapons, no cannon, no watermark. Deck windlasses are short paired horizontal transverse drums with rope and a low frame; never longitudinal gun barrels or carriages. No floating parts, extra masts, modern electronics or unrequested ships. No orange rust on wooden hulls; no wood grain on metal hulls. Lake scenery and weather are artistic staging.",
