Radio Button

Radio button, a matte disc 0.03 m across and 0.004 m thick; checked (off, on) sets a smooth glowing accent dot 0.012 m across on it; label (off, on) adds a flat decal slot to its right. Hover floats it up and glows; pressed settles it; selected holds it down.

风格：low-poly, flat-shaded vertex colors, no textures, 2 materials: the shared opaque one plus a distinct surface (glass, water or chrome), which stays its own mesh through mergeAssets rather than merging into the rest; shares palette and scale with its kit
