体素版克卢日-纳波卡广场飞越：同一提示词双模型对比

Build an interactive voxel-style 3D world of a real historic city square in Romania, viewable in the browser. Show a large pale paved plaza dominated by a tall Gothic church with a steep red roof and a slender clock tower, an equestrian statue, fountains or water features, rows of trees with blocky green crowns, and surrounding buildings with terracotta roofs, plus streets with small cars and many tiny pedestrians. Use a soft blue sky with blocky clouds and distant green hills. Add a guided flyover camera that circles the church and sweeps across the square, with a small caption showing the location name, and let the user also take control of the camera. Use Three.js with instanced cubes or boxes for performance, in a single HTML file if possible. Done means a recognizable, lively square that runs smoothly and can be compared against another model's version built from the same brief.
