Dim Apartment Sofa Portrait

Create a realistic intimate lifestyle portrait of {argument name="subject" default="a young adult woman"} lounging on her stomach on a dark charcoal sofa in a dim modern apartment at night, holding and looking over a smartphone near the bottom foreground. She has {argument name="hair color and style" default="dark brown shoulder-length straight hair swept to one side"}, fair skin, a calm slightly dreamy expression, glossy natural lips, and thin round metal eyeglasses with subtle green-blue phone reflections on the lenses. She wears {argument name="outfit" default="a cream silk camisole with lace trim and thin straps, with matching light shorts"}. Pose her diagonally across the couch with elbows forward, hands around the phone, shoulders and upper torso closest to the camera, one bent leg visible behind her. Use warm low ambient apartment lighting mixed with cool phone glow on her face and fingers, shallow depth of field, soft cinematic bokeh, realistic skin texture, natural proportions, and a candid indoor photography feel. Background: blurred beige walls, a dark hallway or kitchen entrance on the left, a small wall thermostat/switch on the back wall, and minimal furniture, all unobtrusive. Composition: vertical 2:3 portrait, eye-level slightly above the couch, 35mm lens look, close focus on face and hands, no text, no watermark, tasteful fashion/lifestyle mood, not explicit.
