接合部の詩学：新素材は決して旧石に触れない

Design a museum intervention in the manner of Carlo Scarpa where every new element stops just short of the historic fabric, separated by a deliberate shadow gap so old and new never actually touch. Compose a raw concrete plinth floating a few centimetres clear of a medieval stone wall, a blackened steel beam carried on small bronze shoes rather than bearing directly, visible gaps at every junction, water-stained old stonework left unrestored, low raking daylight emphasising each separation, close oblique view of the junction, 50mm lens, architectural photography, ultra photorealistic, 8K
