Folded Storm Sky Landscape

Create a vertical cinematic surreal landscape photograph in a cold blue-gray palette: a lone human figure, {argument name="subject" default="a solitary person in a dark coat"}, stands centered near the bottom of a vast barren rocky plain, seen from behind as a tiny silhouette for scale. The horizon is low, with distant smooth snow-dusted mountains and layered ridges stretching left and right. Above, the entire sky appears to fold and curl like an immense ocean wave or fabric tunnel, with huge sweeping bands of dark storm clouds arcing from the upper left down toward the horizon and curling back across the frame. The cloud structure should feel physically impossible yet photorealistic, with dramatic depth, turbulent texture, illuminated silver-white cloud edges, small breaks of pale blue sky, and glowing sunlight diffused from behind the clouds near the horizon. Use an ultra-wide-angle lens perspective, strong vertical scale, subtle radial motion blur at the ground edges, high dynamic range, volumetric light, crisp atmospheric detail, and an awe-inspiring apocalyptic mood. The ground should be dark, gravelly, wet-looking, and textured with scattered stones, leading lines drawing the eye toward the tiny figure and the folded sky. No text, no buildings, no extra people, no animals, no watermark.
