Wrist Menu Band

Wrist menu band, a floating open cuff, no arm: a smooth 220 deg arc of thin 0.005 m band round the x axis (inner radius 0.036 m), opening toward -z; on the crown slots (2-5) matte discs 0.024 m at 0.036 m pitch float off it, each a decal slot.

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
