The changing word sits in a solid pill that squishes like jelly each time the next word rolls up into place. A vertical track with a repeated first word keeps the loop free of jumps.
Also known as: rotating badge text, pill word carousel, animated tag headline.

em, so the whole thing scales together. Currently previewing 40px.transition or animation
shorthand. Staggered delays are relative, so they keep their rhythm.
