Create a photorealistic vertical portrait of a young adult woman seated indoors beside a softly lit window, framed from the upper torso to the top of the head. She has long, thick, wavy dark brown hair falling over one shoulder, with natural shine and loose strands. She wears a fitted ribbed knit deep purple turtleneck sweater with long sleeves, emphasizing the fabric texture, vertical ribbing, and soft folds. Her hands are gently clasped at her waist near the bottom of the frame. The face is deliberately hidden by a large centered opaque square censor block in warm brown tones, covering the eyes, nose, and most facial features while leaving some hair and one ear visible. Use realistic skin texture on the visible hands, shallow depth of field, soft window light from the left, a warm neutral beige interior background, natural shadows, and high-detail DSLR-style photography. Add a faint semi-transparent watermark reading AI conia in the lower-left corner.
