プレゼン：未来の街をひと目で伝える

An original, polished commercial visual for a fictional unbranded product. 8-second continuous video, coherent object geometry and physically believable motion, rich studio lighting, crisp professional detail. No brand logos, no lettering, no captions, no watermark. Silent. A charming original isometric miniature sustainable city on a warm white background. A small park opens as trees gently grow, two simple wind turbines turn, solar panels gleam, and a single small electric shuttle travels along a curved road. Camera slowly circles the city clockwise, revealing the whole model, crisp white and mustard yellow buildings, restrained green foliage, no text or recognizable real landmarks.
