Concrete Skate Stair Set

Poured-concrete plaza stair set 2m wide x 4m deep on the 2m grid, 0.15m risers and 0.3m treads climbing to a flat top landing that fills the rest of the depth; height knob.

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
