折り畳まれたコンクリートの内部：急峻な洞窟のような聖域

Design a church interior in the manner of Gottfried Böhm where the folded concrete shell is left entirely raw inside and the space feels excavated rather than built, with light entering only where two planes fail to meet. Compose angular grey concrete planes converging overhead at irregular heights, narrow ribbon openings at the fold lines glazed in deep red and blue, a rough dark stone floor stepping down toward a plain altar, simple timber pews scattered rather than aligned, dim contemplative light with two coloured shafts, wide upward view, 24mm lens, interior photography, ultra photorealistic, 8K
