都市の森スタジアム：メガストラクチャーではない大規模会場

Design a large public stadium that feels like an extension of a forest rather than an engineered megastructure. Integrate layered vegetation, timber architecture, natural airflow, and soft human-scale circulation inspired by Kengo Kuma. A stadium ringed by layered timber eaves planted with trees at every level, the outer edge open so breezes pass through, human-scale timber detail at ground level disguising the vast scale, warm daylight through the eaves, eye-level composition, 24mm lens, ultra photorealistic, 8K
