  "generationPrompt": "Create a highly detailed, refined maritime reconstruction illustration of Ora Endress for Michigan Lake Depths. Use the attached newly authored 3D render as the principal visual reference for the ship's overall scale, silhouette, hull proportions and placement of superstructure. Era: Photographed steam-powered Ora Endress form. A clear, peaceful Lake Superior afternoon, soft white cumulus clouds and gently rippled blue-green water with a distant wooded shoreline. Preserve the small pale wooden coastal steamer, long low enclosed house, compact forward pilothouse, short aft funnel and central roof boat. Two thin staffs are not sail masts. Keep the machinery and bow fittings modestly scaled. No sails, fishing nets or invented upper passenger deck. Show the complete vessel afloat at its plausible working waterline, bow to the left, in an elegant three-quarter view with comfortable margins. Underwater hull naturally hidden by the lake. Realistic museum-quality painted illustration, finely observed period woodwork, rigging where present, natural light and convincing fresh water. Landscape 3:2 composition. No modern buildings, text, captions, logos, map pins, archival border or display base. Weather, shoreline and lighting are artistic scene choices, not a recreation of a documented voyage or loss. Preserve the reference's defining geometry; do not invent extra masts, funnels, tall superstructure or sails. This is supplemental interpretive artwork, not documentary evidence or an exact model render.",
