/**
 * What you can do to a selection.
 *
 * Appears only when something is ticked — a toolbar you did not ask for is
 * clutter — and it lives inside the list component rather than beside it, so
 * filtering down to nothing does not unmount the bar and silently throw the
 * selection away.
 *
 * Tagging adds and removes rather than replacing. "Tag these nine as fintech"
 * must not mean stripping the size and location off all nine, which is what a
 * replace would do.
