## How it was made

Built in code from published dimensions and photographs, with no image-to-3D generator and no one else’s mesh. 3D model: built by Space Radar from published dimensions and pictures (IHEP/CAS, CC BY 4.0; CNSA/Siyu Zhang/Kevin M. Gill, CC BY 2.0).

built by this project in code (release 1.3.0 stage W3-c's scripts, one a craft, on W1-c's part library, kept with the stage's notes), from the cited dimensions and the pictures under `references`; no image-to-3D model was used, and no published mesh (CNSA publishes none under terms that allow a derivative, and NASA's 3D Resources and NASA Science's 3D models have none of these craft; read 2026-10-20)
