林荫大道：连续树冠覆盖的人行遮荫

Render a Taiwanese boulevard where a double row of mature trees forms a continuous canopy over the sidewalks, treating shade as basic infrastructure in a subtropical climate. Show the trees planted close enough that the crowns touch and merge into an unbroken green ceiling above the walking route, with the canopy lifted well clear of pedestrian heads and shopfront signage. Use appropriate large-canopy species for Taiwan — banyan, camphor, Formosan sweetgum — with honest trunk character and aerial roots where relevant. Render the light as dense dappled shade on the paving, with hot bright sun visible on the exposed carriageway beyond, so the temperature difference is visually obvious. Detail the tree planting in a continuous trench with groundcover rather than isolated pits, and keep the walking surface flat and free of root heave. Show pedestrians choosing the shaded side, an older couple on a bench, a vendor with a cart. Include Taiwanese mixed-use buildings behind. Eye-level view down the shaded sidewalk, midday summer light, photorealistic foliage and paving.
