光の十字：光そのものを信仰の形にする

Design architecture where a precisely cut cross-shaped opening transforms natural sunlight into the primary spiritual element, allowing light itself to define sacred space inspired by Tadao Ando. A dark concrete chapel with a single cruciform slot cut through the end wall, brilliant daylight forming a glowing cross against total shadow, rough timber floor and benches, no other light source, eye-level symmetrical composition, 35mm lens, ultra photorealistic, 8K
