"""``Counter`` displays the current value as a running count.

Reach for it when there is no meaningful total to show a percentage or
fraction against -- just the raw count so far. Compare ``SimpleProgress``
("5 of 47") when a total is known, and ``UnitProgress`` when the count
should carry a unit label.
