Lava Field Tile

A 4 x 4 m tile of black lava field on the kit's 0.06 m slab, base at y=0, tiling-edge vertices exactly at x and z = +/-2 with flat sides on the module edge, the relief settling to one shared height band along every edge so any copy butts any other.

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
