AI Video Prompt: People Standing on Transparent Sky Glass Platform…

Create a realistic vertical 9:16 smartphone travel video showing a group of adult visitors standing on a transparent glass observation deck inside a very tall skyscraper. The visitors are lined up near large angled glass windows, leaning slightly forward and looking down through the transparent floor at the city far below. The camera is handheld at human height, slowly moving to reveal the glass platform, visitors' feet, modern building structure, and panoramic urban skyline. Maintain realistic daylight, natural reflections on glass, authentic human posture, casual travel clothing, and documentary-style camera movement. Keep the same people, same positions, same architecture, same city view, and same realistic physics throughout. No extra characters, no artificial effects, no fantasy elements.
