  "generationPrompt": "Use case: historical-scene. Create detailed realistic maritime reconstruction artwork of B.W. Blanchard in the early working appearance shown before 1897. Reference image 1 is our modern interpretive 3D model: follow its complete long wooden hull, two massive curved pale wooden longitudinal support arches with posts and braces, ONE bare working foremast with a raised gaff, ONE tall narrow black aft funnel, forward wheelhouse and low aft cabin, open central cargo-deck arrangement. No sails. Preserve these distinctive features; do not substitute a generic schooner or modern freighter. Show the entire approximately 221-foot vessel in an elevated starboard-bow three-quarter composition on calm blue Lake Huron near a distant forested Thunder Bay shoreline, warm late afternoon light, a little smoke, rich weathered timber grain, fine rigging and realistic water. Entire mast, gaff, hull and stern within frame with breathing room. No modern electronics, extra masts, extra funnels, lettering or watermark. This is supplemental interpretive historical art, not an archival photograph or archaeological proof.",
