| LTM — FastAPI server for the Hugging Face Docker Space. |
| |
| A 3D-enabled 2D design app. This server is intentionally minimal: it serves the |
| static single-page app (index.html) and any sibling assets. No AI proxy — the app |
| runs fully in the browser (Fabric.js for 2D, Babylon.js for 3D). |
| |
| Kept as a dynamic FastAPI/Docker server (not a static Space) so future server-side |
| features (asset storage, share links, etc.) can be added without re-plumbing hosting. |
