Basalt Field Wall Run

A 4 m run of the island's dry-stone field wall (pirca), the black porous rubble walls that cross the grassland, unlike the store's coursed grey village walls: about 1.1 m tall and 0.8 m thick, piled from dark grey-black vesicular basalt field stones.

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
