Aquascape Rock Arch

A bonded aquascape arch 0.5 m wide and 0.35 m tall spanning two lumpy bone-coloured rock legs with a clear swim-through opening, coralline mottling on the crown and a flat two-pad footprint at y=0.

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
