Playing Card

Standard playing card 0.063m x 0.088m with rounded corners and a crimson diamond-lattice back: suit knob, rank knob (ace to king, with bold simplified pips and court faces as flat polygons), side knob (face up, face down).

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
