Still Woman on Fast Subway Platform

Create a square, photorealistic cinematic street-photography image on a subway platform with a strong speed effect: a single seated young woman remains sharp and still in the center foreground while a subway train and platform background streak horizontally with heavy motion blur, suggesting a train rushing past at high speed. The subject sits on a dark bench facing the camera, leaning slightly forward with relaxed posture, knees apart, hands hanging together between her knees. She has shoulder-length wavy hair_color hair and an intentionally anonymized softly blurred face with no readable facial features. Her outfit has exactly 4 visible clothing items: an oversized dark charcoal-green wool coat, a white shirt, light blue straight-leg jeans, and dark shoes or socks. Add one small dark shoulder bag strap visible on her left side. The background should show the side of a subway train with windows and doors smeared into horizontal bands of white, gray, blue, black, and warm brown, while the subject remains comparatively crisp. Use low indoor station lighting, muted colors, shallow depth of field, natural film grain, realistic proportions, centered composition, eye-level camera, 1:1 aspect ratio, and a long-exposure panning look where only the background is blurred and the person is frozen.
