  "generationPrompt": "Wooden steam-and-sail ore freighter Smith Moore around1880. Exactly THREE gaff-rigged masts with three mainsails, one tall aft black funnel and TWO white cowl ventilators beside it. Light painted wooden topsides. Arched aft-house windows. Two black horizontal steam-winch drums on a LOW FRAME amidships, cross-ship oriented drums with no muzzle. Soft bright morning on Munising Bay; tree-covered shore. No hull names. 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.",
