Brutalist Geometric Indoor Corridor

Prompt

Vertical 9:16 cinematic shot of a vast dark brutalist interior. Massive stacked white concrete volumes form a deep geometric corridor with sharp rectangular openings. Thin glowing white light frames outline doorways and floating architectural slabs, creating layered portals of light receding into darkness. Silhouettes of a few people standing still or slowly walking through the space, one in the foreground, others distant. The scene rhythmically fades almost to black then the light architecture reappears. Minimal, monochromatic, high contrast, volumetric light, clean CGI architecture, slow camera, immersive installation atmosphere, no text, no color.
