Gold Ingot

One cast gold bar about 0.22m long, a chamfered trapezoid block with a stamped seal on the top face, which composers clone into stacks and rows; carries a metal knob (gold, silver, dull lead) and a condition knob from bright to scratched and dented.

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
