11/// Click-to-add a pin. Every block in scope that may take one shows its free
12/// slots' markers; a click on one adds the pin and opens its name for editing,
13/// as the "(+)" beside a selected block does. The click is a stamp
14/// ([`crate::stamp`]), so a cell dropped off the cluster onto a marker adds the
15/// same pin.
