| `image`         | file   | Yes      | -        | -     | -          | -              | A single, clear photo of ONE object (e.g. a product shot). The background is removed automatically — avoid scenes, clutter, or multiple objects. The model infers the object’s unseen sides from this one view, so a well-framed, unambiguous angle gives the best result. |
| `numGaussians`  | number | No       | `262144` | 32768 | 262144     | -              | Target number of 3D Gaussians; higher is more detailed but heavier.                                                                                                                                                                                                        |
