Overhead Spiral Staircase Portrait

Create a hyper-realistic cinematic 35mm photograph from an extreme overhead perspective, looking straight down into an enormous circular spiral staircase. A lone {argument name="subject" default="middle-aged man"} stands perfectly still at the exact center of the spiral, far below the camera, looking upward. He wears a {argument name="coat color" default="dark brown"} overcoat, beige sweater, dark trousers, and brown shoes, with one hand raised near his chest as if holding his glasses or collar. The staircase forms multiple concentric rings around him, with stone steps, cream concrete undersides, dark metal railings, and a polished wooden handrail; the repeating curves should create a hypnotic vortex descending into shadow. Use warm muted beige, brown, and gray tones, soft dusty light from above, subtle haze, deep shadows, realistic architectural texture, and dramatic film grain. Compose vertically in a 3:4 frame with the man centered, the circular stairwell filling the entire image, strong radial symmetry, and a tense surreal atmosphere of isolation and vertigo. No text, no watermark, no extra people.
