     Open/closed is plain `display`, with NO transition or animation.
     The app re-renders continuously, and under that churn both a
     transition (pinned in playState "running" with fill "backwards") and a
     one-shot keyframe animation (restarted before it could finish) held their
     *from* values — opacity 0 — producing a panel that was in the DOM,
     matched its CSS rule, and still never appeared. An instant open is not
