"""The printer card's Power row and HA row, over the real API (#2830).

The ranking itself is unit-tested. These drive the two endpoints the card calls,
with real rows in the database, because the ranking is only worth anything if
the endpoints use it -- and because the second endpoint has to agree with the
first about which plug is the main one or the card draws it twice.
