  "generationPrompt": "Grecian steel bulk freighter: black painted STEEL hull, broad pale sheer band widening forward at raised forecastle, compact single-storey rounded-corner pilothouse with wraparound open bridge, bow jackstaff and slender vent pipes, two masts, one tall aft funnel, seven model hatchcovers. Restrained smooth steel plating, painted metal not wooden planks. Cool bright cloudy Lake Huron scene with low wooded shoreline, mild ripples. 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.",
