Create one continuous 13-second video in a 9:16 aspect ratio, presenting an off-plan high-rise lobby as a 3D architectural render that seamlessly becomes lifelike footage. [00-04s] Start with a symmetrical 24mm wide-angle render, the camera making a slow vertical tilt down from a sculptural ceiling to a reception desk, stone flooring, brushed metal details, and layered seating; use bright, soft architectural lighting with immaculate surfaces. [04-09s] During the uninterrupted tilt and forward glide, introduce realistic variation: polished stone develops subtle reflections and fine texture, metal loses its artificial perfection, daylight from the entrance changes naturally across the floor, and indoor plants show slight leaf movement from concealed ventilation. [09-13s] End with photorealistic footage as two properly dressed adults enter calmly, a uniformed security professional observes from a respectful distance, and the automatic doors open with believable timing. No readable text, logos, watermarks, brands, or signage. Maintain realistic acoustics, scale, materials, and human motion. Sound design: begin with a clean digital tone, transition into quiet lobby reverberation, soft footsteps, ventilation, door motors, and subdued ambient activity.
