Grown-over dirt tile

4x4m grown-over dirt ground tile, 0.1m slab with a flat walkable top at y=0 and flat vertical edges matching every other tile, shallow rut and hollow relief in warm browns with green creeping in at the edges, clean surface with no scattered props.

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
