A smooth, perfectly stabilized forward camera movement through a long empty corridor. The camera glides slowly forward as if mounted on a high-end cinematic dolly or floating in the air. No shaking, no jitter, ultra-stable motion. The corridor is well-lit with soft natural light coming from patterned concrete walls on the left side, casting subtle shadows. On the right side, there are simple wooden benches and white walls. The perspective remains centered, with strong depth and vanishing point. Realistic lighting, cinematic look, high detail, 4K quality, no people, no movement except the camera. Slow and continuous motion, calm atmosphere.
