Notification Badge

Notification badge, a smooth flat pill glowing in the accent, 0.004 m thick; kind is count (0.024 m tall, a decal slot for the number, digits 1-3 widening it, ends unchanged) or dot (a plain 0.012 m disc). Hover floats it up slightly larger.

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
