The success-style checkmark as a checkbox: a ring traces itself around the circle, the tick draws inside it, and the icon gives a small bump when it lands. Two SVG strokes, no fill.
Also known as: success checkmark animation css, checkmark circle animation, circle tick animation.

Currently previewing #3b82f6.--chk-size. Every other dimension is in
em, so the whole thing scales together. Currently previewing 24px.transition or animation
shorthand. Staggered delays are relative, so they keep their rhythm.
