Level Meter

Level meter, a slim vertical matte pill track 0.012 m wide, 0.004 m thick; bars (8-16) sets its length in 0.012 m steps and level (0-1, default 0.6) fills it from the bottom with a smooth glowing accent pill. Hover floats it up and glows; pressed settles it.

风格：low-poly, flat-shaded vertex colors, no textures, 3 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
