オリンピック会場：ケーブル支持屋根下の儀式空間

Design an Olympic arena inspired by Kenzo Tange. Create a cable-supported roof spanning a large competition venue with monumental public plazas, ceremonial entrances, flexible seating, and exposed engineering systems that celebrate structural beauty. Two massive concrete masts carrying a main cable from which a sweeping steel roof hangs in a shell-like curve, the roof edge spiralling to the ground, a broad ceremonial plaza approaching the entrance, clear sky with strong directional sun, low wide view emphasising the sweep, 24mm lens, architectural photography, ultra photorealistic, 8K
