Numeric Keypad

Numeric keypad, a thin frosted glass plate 0.005 m thick, 0.03 m corners, with blank matte rounded keys 0.044 m at 0.052 m pitch floating 0.004 m off it, each a decal slot; layout is 3x4, 4x4 or 4x5; active picks the key. Hover floats that key up and glows.

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
