/* The wrapper's own height collapses via CSS grid's 1fr->0fr row trick
   (not display:none) so no blank gap is left behind once it's gone — the
   flex `gap` above collapses with it via the matching negative margin-top.
   The card itself slides out to the right and fades as that happens, so
   it reads as a deliberate slide-away, not just a shrink. min-height: 0 on
   the card is required for the grid row to reach a true 0 — without it,
   the card's own padding sets an implicit minimum and the row stalls
   there instead of collapsing fully. */
