A faint circled check that draws itself in: the ring traces around from the top, then the tick strokes in. A pathLength of 1 on each shape makes the dash math the same for both.
Also known as: check icon animation css, success icon stroke draw, tick draw hover.

Currently previewing #3b82f6.--hfx-size. Every other dimension is in
em, so the whole thing scales together. Currently previewing 16px.transition or animation
shorthand. Staggered delays are relative, so they keep their rhythm.
