Plaza Water Basin

Man-made reflecting basin exactly 4x4m on the grid, a white chamfered rim standing 0.4m above the plaza with a dark inner bowl and a flat inset water plane just below the rim, one pastel-cyan light strip recessed under the rim overhang.

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
