Build source and procedural mesh design: newly authored for this miniature project. No third-party 3D meshes, fonts or image textures.
Selected concept: generated with the built-in image tool; exact prompt, output hashes and creation chronology are documented.
Public tourism/operator photographs, Google Maps responses and any government document images remain reference-only with rights retained by their owners. Public availability is not a redistribution license. These reference files are excluded from the delivery allowlist. Final geometry uses plain/procedural materials, not those photographs as textures.
Blender: external GPL software used by the later build workflow; Blender executable is not bundled.
