  "generationPrompt": "Create a polished, highly detailed maritime reconstruction illustration, landscape 3:2. Use the supplied newly authored 3D model render as the controlling reference for the hull proportions, mast count, sails, funnel and cabin arrangement. Three-quarter elevated view of the whole vessel afloat on calm blue-green Lake Huron, soft late-afternoon daylight, subtle distant wooded Michigan shoreline, fine timber and canvas textures, realistic rigging, no cutaway, no text or labels, no people prominently shown. This is modern interpretive artwork, not an archival photograph. Do not invent extra masts, sails, funnels, ornate carvings, weapons, flags or major structures. E.B. Palmer, a 138 ft three-masted wooden Great Lakes schooner, interpreted late sailing form c.1889–1892. Exactly three masts, three cream gaff sails and two triangular headsails, five sails total. Brown timber hull, pale modest aft cabin, two covered hatches, ship's boat stowed on deck. Keep clear mast spacing as in the reference. No machinery or smoke, no sandstone piled on deck. The reference is an evidence-informed comparison-based likeness with unresolved rebuild details.",
