      "generationPrompt": "Create one polished, realistic maritime historical reconstruction illustration of Tramp, Wooden fishing tug, Gill-net fishing-tug interpretation. 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: cold misty dawn, steel-blue water and a low amber horizon; no ice collision. 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 55 ft, beam 13.4 ft. No deployed sails."

  "generationPrompt": "Edit the supplied AI interpretive ship illustration with a narrow correction. Remove orange rust stains from the wooden hull, cabin, doors and wheelhouse. Retain wooden construction: horizontal timber planking with grey age and slight paint wear only. Preserve hull shape, enclosure, doors, low wheelhouse, exhaust, calm lake and sunrise fog exactly. Preserve framing, aspect ratio, lighting and all unmentioned details. Keep deck winches as squat transverse rope drums with solid flanges, never barrels. No text, no lettering, no name boards, no guns, no weapons, no cannon, no watermark. No extra masts or floating parts. Do not add modern equipment. This remains an interpretive illustration, not historical photographic evidence.",
