Floating Ledger City — Anime Worldbuilding Reference Map

Generate a detailed anime-style worldbuilding reference sheet for a misty, salt-fog ledger city, complete with a quarantine inspector character, port scenes, tools, and ship diagrams. Use it as a Concept Art starting point for GPT Image 2: keep the visual structure and style constraints intact, then swap in your own subject, brand, or scene.

This prompt is organized as structured JSON with fields such as type, language and text, main title, subtitle, central character, layout, and environment details. Keeping that hierarchy helps the model separate the subject, layout, interface elements, and detail constraints.

Start with small changes to subject, scene, camera, and color, then generate a few variations to compare composition and detail without turning the page copy into keyword stuffing.
