自然光的展厅：天花光带与无框接缝

Design a top-lit gallery in the manner of Yoshio Taniguchi where daylight arrives through a ceiling of continuous translucent panels, so the whole soffit glows evenly and casts no directional shadow at all. Compose seamless white walls meeting the floor with a recessed shadow gap and no skirting, a pale oak floor, one large painting on an otherwise empty wall, no visible light fittings or vents, perfectly even soft illumination, one-point view down the room, 24mm lens, interior photography, ultra photorealistic, 8K
