Estrae mappe di normali in spazio tangente e mappe di profondità da un'immagine di riferimento. Modifica le parentesi per produrre mappe singole o doppie.

### Full prompt
```text
Generate a [surface normal map and depth map side-by-side] from the reference photo.
- Normal map: Standard tangent-space RGB encoding where R = X direction, G = Y direction, and B = Z direction. Normal directions follow the local geometry, shading, and contours with smooth transitions.
- Depth map: Continuous grayscale depth map where white is near to the viewer and black is far, with physically plausible spatial gradients.
Constraints: Maintain the exact framing, resolution, and aspect ratio of the reference photo. Do not add new artistic elements, repaint, or stylize; infer only plausible micro-geometry and depth structure without noise.
