可漫游的Frutiger Aero风3D世界：泡泡、玻璃与绿色山丘

Build an explorable 3D world in the Frutiger Aero style of the early 2000s, running in the browser with WebGL. Place the viewer in a clean plaza with glossy white curved paths edged in teal, round pools with mushroom-shaped fountains, glass domes and glass-walled buildings. Surround it with rolling bright green hills dotted with round trees, tall grass blades, floating soap bubbles, soft clouds, distant hot air balloons and birds under a vivid blue sky with a lens-flare sun. Use a saturated sky blue, aqua, lime and white palette with soft reflections. Add a small location label in the corner. Let the user walk or glide through the scene with mouse or touch controls. Deliver a deployable web page. Done when the world feels airy, optimistic and nostalgic from every viewpoint.
