Turf Pitch Tile

4x4m mown turf tile, 0.05m slab, base at y=0, tiling vertices exactly at +/-2m with dead-flat sides; marking knob = plain, side line, halfway line, centre circle, penalty arc, penalty spot, goal area, corner arc.

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
