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 MERMAID, occupying 55-65% of the frame, filled with medium-light gray (65-75% value) as the near plane. Simple clear mermaid pose: long flowing hair, human upper body, gracefully curved fish tail with a fin at the bottom, arms gently posed. Create volume ONLY through a soft smooth gradient: slightly brighter at the body 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 facial features, NO scales, NO hair strands, NO outline strokes, NO text, NO harsh gray jumps. Smooth, minimal, clean depth map: a volumetric yet simple and highly readable mermaid silhouette on a pure black background. Gentle gradients, high contrast between black background and gray mermaid.
