Retail Podium Arcade

Two-floor commercial podium with a 12x12m footprint and dead-flat side walls at the footprint edge, glossy white chamfered mass over a recessed ground-floor arcade of fat rounded piers.

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
