Photoreal architectural photograph of a small floating cedar teahouse on a still mountain lake in early autumn mist, 16:9 landscape, viewed from a wooden shore path approaching the dock. Key subjects first: a square one-room cedar teahouse with a dark weathered hipped shingle roof, four sliding shoji paper screens on the lake-facing side, a narrow engawa deck with simple vertical railings, two squat granite stone lanterns flanking the dock entrance, and a small tied wooden rowboat at the right side of the floating platform. The platform sits on dark timber pontoons just above the water; pale cedar walls show soft grain; copper rain chains hang at two corners. Behind the teahouse, layered blue-gray mountains fade into fog; pine forest lines the far shore; the water mirrors the roof as a soft blur. Light: low morning sun from the left, cool mist, warm wood highlights, quiet contemplative mood, crisp architectural detail, true colors. No people, no smoke plumes, no neon, no readable text, no watermark.
