The collapsed activity / agent-run cards (ClideHolderCard) wrapped themselves
in 3px vertical margin, while the prose ConversationCards use 14px bottom /
0 top. So a folded card floated ~17px below the previous card but hugged the
next one at 3px — the uneven gap the earlier bordered-padding tweak didn't
address. Give the holder the same bottom-14 / top-0 margin.
The holder-card golden is regenerated for the taller frame. The copy-button
holder test parks its hover and advances past the tooltip show-delay so the
(exit-uncancellable) Future.delayed timer fires instead of leaking.
