私域界面齐平：骑楼与人行道的高差消除

Show a Taiwanese street where the traditional arcade in front of the shophouses has been levelled and joined seamlessly to the public sidewalk, removing the steps and ramps that each shop owner had built independently. Render one continuous plane running from the shop thresholds out to the kerb, with the old patchwork of tiled steps, private ramps and mismatched heights gone. Keep a subtle change of paver colour to mark where private arcade ends and public sidewalk begins, but hold both at exactly the same level. Show the covered arcade columns of the shophouses in the middle distance, with ground-floor businesses spilling gently outward under the roof — a pharmacy, a noodle shop, a bank. Include a wheelchair user rolling straight from the sidewalk into the arcade without changing direction, and a delivery trolley being pushed easily. Use a low camera angle close to the ground so the flatness of the surface is the subject, with raking afternoon light exaggerating any remaining level change. Realistic tile and terrazzo textures, honest documentary lighting.
