Letters pop in from nothing with a springy overshoot, one after another. The overshoot comes from a cubic-bezier that goes past 1, so no keyframe juggling is needed.
Also known as: bounce in letters, elastic text, scale in letters.

Currently previewing #3b82f6.--txt-size. Every other dimension is in
em, so the whole thing scales together. Currently previewing 40px.transition or animation
shorthand. Staggered delays are relative, so they keep their rhythm.
