When I rewrote the original 'Per-card action buttons … moved into
the sticky #selection-bar (see renderSelectionBar) which appears
when the operator has at least one agent selected via the icon
click' comment to use the docs ref, I shrunk part of it but left
the second sentence as a dangling fragment glued onto the new
short ref. Collapse cleanly: docs ref + the still-useful
`needs update ↻` chip note.
