Five avatars open into a rowThe gap opens from an overlap to a small space, each width grows from the avatar to its name, and the names switch on 50 ms apart.
Two properties changeThe gap between authors and the width of each one. Height stays at 24.
An ease out, not a brand curveThe gap and widths use cubic-bezier(0, 0, 0, 1). The brand motion spec's Exponential is a different curve.
