  "generationPrompt": "Create one polished, realistic maritime historical reconstruction illustration of Sea Fox, Wooden steam yacht, Steam-yacht career, circa 1915. Landscape composition, lake visible in background, entire ship and all spars in frame with generous margins. Use the supplied newly-authored 3D render as the structural reference: preserve its hull proportions, number of masts and funnels, working arrangement and ship type. Make it look like a richly detailed physical vessel afloat, not a toy or studio model. Setting: clear late-summer morning with a thin lake haze. Low distant Great Lakes shoreline, believable fresh water, no mountains or modern skyline. Treat this as interpretive artwork, not documentary evidence. No text, lettering, flags, pennants, logos, labels, captions or watermark. No people in distress or disaster. Do not add extra masts, funnels, sails, cargo cranes or decks. Ship length 101.6 ft, beam 16 ft. No deployed sails.",
