透水铺面人行道：雨水下渗与街道降温

Show a Taiwanese sidewalk surfaced entirely in permeable paving during and just after a summer afternoon downpour, with no standing water anywhere on the walking surface. Render large-format permeable concrete pavers in a warm grey with open joints filled with fine aggregate, the surface visibly damp but not puddled, while the adjacent asphalt carriageway sheets with runoff and reflects the sky. Show water entering the paving joints rather than running along the kerb. Include a shallow linear infiltration strip planted with sedges at the kerb line, receiving overflow through gaps in the kerb stone. Place pedestrians under umbrellas walking normally on the dry-footed surface, and a scooter throwing spray on the flooded road behind them to make the contrast obvious. Show heavy tropical sky, wet building façades, saturated greens from the street trees, and steam beginning to rise from the asphalt. Eye-level view with a slight downward tilt so the paving surface fills the lower half of the frame. Photorealistic wet-surface rendering with truthful reflection behaviour.
