  "generationPrompt": "Nordmeer1954–1966 STEEL diesel cargo ship: central stepped white superstructure, compact rounded motor funnel with dark cap, five cargo hatches three forward and two aft, two lifeboats one each side, three unequal cargo-mast stations with derricks. Match exact model. Smooth painted STEEL hull with subtle welded plate seams, NEVER wood planks. Restrained realistic weathering only. Low wooded Lake Huron shore under bright cool cloud cover, gentle ripples. Use the supplied GLB render as primary geometry reference, preserving complete silhouette, proportions, all mastheads, exact number of masts/funnels, cabin and deck fittings. Landscape full ship three-quarter view, detailed interpretive museum historical scene with lake background, plausible period construction. No text, no lettering, no name boards, no guns, no weapons, no cannon, no watermark. Deck windlasses are short transverse winch drums wound with rope, not gun barrels. No floating parts or extra masts. No wood grain on steel or iron; no orange rust on wooden hulls. No modern electronics or synthetic yellow lines. No invented ships.",
