ステンレス鋼のシェルルーフ：ヘルメットのようなスタジアム

Design a city gymnasium in the manner of Fumihiko Maki's Tokyo Metropolitan Gymnasium — a great stainless-steel shell curving down almost to the ground with a raised ridge along its spine, so the main hall reads as a helmet or an upturned hull sitting on a stone podium. Compose a sweeping matte stainless roof with a fine standing-seam pattern, a curved ridge lifting at both ends, a granite plinth with broad steps, a separate smaller domed volume alongside, plane trees around, cool overcast light rippling on the metal, low three-quarter view, 24mm lens, architectural photography, ultra photorealistic, 8K
