Photorealistic Candid Street-Fashion Portrait with Extreme Bokeh

A highly specific prompt designed to generate a photorealistic, candid street-fashion portrait with extreme shallow depth of field. It mandates a 4:5 vertical composition, precise subject placement (young woman in a beige trench coat looking back at the camera), and detailed foreground/background blur (bokeh) featuring blurred human shapes and warm city lights, aiming for a cinematic teal/orange color grade.
