Radial Pie Menu

Radial pie menu, a thin matte disc menu 0.28 m across, 0.005 m thick: a small centre disc and segments (3-8) smooth wedge pads with even gaps, each holding a glyph or decal; open (0-1) slides wedges out from the hub in order; active picks a wedge.

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
