Plaza Fountain

Colonial plaza fountain 2.6 m across on the 2 m grid: an octagonal cantera basin 0.6 m tall with a moulded rim and a stepped kerb, a carved central pillar and a scalloped upper bowl spilling into it.

风格：low-poly, flat-shaded vertex colors, no textures, 2 materials: the shared opaque one plus a distinct surface (glass, water or chrome), which stays its own mesh through mergeAssets rather than merging into the rest; shares palette and scale with its kit
