Slider

Slider, a slim matte pill track 0.24 m long (length 0.12-0.4 m), 0.006 m wide, 0.003 m thick, with a smooth disc thumb 0.024 m across floating 0.004 m off it; value (0-1, default 0.5) places the thumb and the track up to it glows as the accent fill.

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
