Checkmark scale pop

Variant: Scale pop

A filled disc that scales in with a 2% overshoot, then the tick lands inside it. Faster and louder than the draw-on version: use it when the confirmation is the whole payload of the moment and you want it to feel stamped. It starts at scale(0.92), never zero — nothing in the world appears out of nothing.
