Parking Garage

Open deck municipal parking garage, footprint exactly 12x12m, 4 decks at exactly 3m each, 12m total with a flat open top deck edged by a low solid parapet; concrete slab edges with open horizontal gaps between them.

风格：low-poly, flat-shaded vertex colors, no textures, single shared material, so any set of these merges to one draw call; shares palette and scale with its kit
