// GeometryReader — rather than measuring the transcript, whose height the cards' own bottom
// `safeAreaInset` resizes — makes the measurement categorically independent of the card, so
// the card can't feed its height back into the value it's sized from. That feedback was an
// unresolved layout cycle that pinned the main thread at 100% CPU during the push transition;
// it showed up intermittently because a feedback loop only diverges for some content/card-
// height combinations. It bit only the attention path (a card consumes this value; the plain
// composer doesn't), which is why a "Working" tap opened fine and an "attention" tap hung.
