## Full prompt

```text
Generate a surface normal map from the input artwork image.

Output one RGB image where each pixel encodes the surface normal direction in standard tangent-space format:
• R = X direction
• G = Y direction
• B = Z direction

Requirements:
• Maintain the same resolution and aspect ratio as the input image.
• Normal directions must follow the local geometry implied by brush strokes, shading, and contours.
• Do NOT add new artistic elements or repaint the scene.
• Only infer plausible micro-geometry and surface orientation.
• Ensure smooth, consistent normal transitions without noise.

Generate a depth map from the input artwork image.

Output a single grayscale depth map where:
• White = near to the viewer
• Black = far from the viewer

Requirements:
• Maintain the same resolution and aspect ratio as the input image.
• Depth must be smooth, continuous, and physically plausible.
• Infer only geometric depth that could reasonably exist in the original artwork.
• Do NOT add new objects or details.
• Do NOT stylize, repaint, or reinterpret the scene.
• Avoid texture noise; focus solely on depth structure.
