ドラマチックなアトリウムにおける文化的なインテリア：浮遊する階段と抽象的な秩序

Design a contemporary cultural interior inspired by Arata Isozaki. Create dramatic atriums, layered circulation, floating staircases, flexible galleries, and monumental public halls illuminated by skylights and controlled natural light. Balance structural clarity with spatial abstraction to create a timeless civic experience. A tall atrium of pure geometric volumes — a barrel vault meeting a cube — with a cantilevered stair crossing the void without visible support, a grid skylight above, pale plaster and dark stone, a single sculpture below, cool controlled daylight, wide upward view, 24mm lens, interior photography, ultra photorealistic, 8K
