 * finishes). A class that set `animation` on .av-do too would, the instant
 * it took effect, replace that whole property — cancelling the entrance
 * animation and its forwards-held opacity along with it, and since neither
 * replacement keyframe set touched opacity, the element fell back to the
 * base rule's `opacity: 0` for the animation's full duration. That was the
 * "D.O. disappears" bug: it dropped out during the wave, before the idle
 * pulse ever got a chance to start. Keeping wave/idle on a separate element
 * means they can never touch .av-do's opacity or entrance transform at all.
