巨大開閉式屋根のスタジアム：シルバーオーバルとグラススライド

Design a domed stadium in the manner of Hiroshi Hara as a smooth silver ellipsoid resting on a green hill, with an entire grass pitch that floats out through a gap in the wall on an air cushion to sit outside in the sun. Compose the stainless steel shell curving without seams, the huge opening in the flank with the turf platform half emerged, snow-dusted grass slopes around the base, a mountain ridge behind, cold clear Hokkaido light, low three-quarter view, 24mm lens, architectural photography, ultra photorealistic, 8K
