The real cause behind the invisible redact/delete buttons: .card lacked
position:relative, so the position:absolute action buttons (delete, redact)
and the bulk-select checkbox anchored to the viewport instead of the card
and were clipped by .card overflow:hidden. They only showed in list view,
where those elements are position:static. Add position:relative to .card so
all three position within each card. Keep the 0.35 baseline opacity on the
redact button for discoverability.
