Create a realistic close-up portrait photo of a young person with {argument name="hair color" default="vivid rainbow neon hair"}, shaggy medium-length layered hair with a dark crown and saturated bands of magenta, violet, electric blue, cyan, green, yellow, and orange glowing around the sides. The subject is framed from chest to head, facing the camera, wearing a loose {argument name="shirt color" default="black"} graphic T-shirt with distressed white punk-style artwork and the visible words “CHAOS SYSTEM CONTROL,” plus a thin silver chain necklace. Place a large opaque square privacy block directly over the entire face, centered from forehead to chin, filled with a soft muted gradient of tan, mauve, green, and blue, hiding all facial features. Use a warm indoor background with shallow depth of field, dark wood or wall panels on the left, beige curtains on the right, and a softly glowing wall lamp near the upper right. Lighting should feel cinematic and cozy, with realistic skin on the visible neck, crisp colorful hair texture, natural camera bokeh, and a modern street-fashion editorial look.
