透水铺装与排水：场地边缘的收边剖面

Show the edge condition where a sports court meets the surrounding park, with the water-handling logic made visible. Render, in sequence across the frame: the coloured sport surface, a flush stainless slot drain running its full length, a narrow band of dark permeable resin-bound gravel, a low flush kerb of pale precast concrete, and then a shallow vegetated swale planted with sedges and rushes falling gently away into the grass. Detail the swale with a scatter of rounded cobbles along its invert where flow concentrates, and a small stone-lined inlet where the slot drain discharges into it. Show the planting as informal and slightly overgrown, deliberately not manicured, with some grasses leaning over the kerb. Include a park path crossing the swale on a simple flat precast slab bridge. Detail the materials honestly — a tide mark on the cobbles, silt in the swale, moss on the kerb. Show soft light just after rain, with water visibly moving. Photorealistic, technical yet green, low eye-level view along the edge.
