Depth map for a stereogram, 9:16 vertical, 2K resolution, grayscale ONLY — no color, no texture, no pattern. Perfectly clean solid black background (0,0,0) as the far plane. A single centered static silhouette of a SHIP'S WHEEL / HELM (ship steering wheel with spokes and handles), occupying 55-65% of the frame, filled with medium-light gray (65-75% value) as the near plane. Create volume ONLY through a soft smooth gradient: slightly brighter at the object's center, gradually darker toward the edges — no patches, no bands, no stepping. Keep the outline crisp, clean and instantly recognizable, with a soft 3-5px feathered edge all around. NO fine internal details, NO text, NO outline strokes, NO harsh gray jumps. Smooth, minimal, clean depth map: a volumetric yet simple and highly readable ship wheel silhouette on a pure black background.
