Create a pure SVG of a full-body male muscle anatomy figure in FRONT view, matching the uploaded reference as closely as possible. Flat 2D fitness/medical line-art. Light gray background (#e6e6e6), light gray body fill, solid black outlines, consistent stroke width, subtle soft shadow behind figure. Upright pose, arms slightly angled outward, hands relaxed downward. Recreate the same silhouette, proportions, spacing, and muscle segmentation: delts, chest, biceps, forearms, abs, obliques, quads, knee transitions, lower legs/calves. No text, no labels, no watermark, no border, no realism, no gradients, no redesign. Output SVG markup only, one viewBox, closed paths, grouped regions with readable ids for recoloring later.

The image shows a black and white silhouette of a man with his arms outstretched against a white background. His body is clearly visible, with a muscular physique and a determined expression on his face.
