Frame suit and hand jokers with this run's actual deck and levels

Buy-area tooltips on suit-tagged jokers now show the deck ratio
('Your deck: 18 of 52 cards are Hearts', from card.base.suit -- the
field vanilla scores by) and hand-cluster jokers show the hand's level
when it has been built past 1. Pure context: the pairwise score never
reads the deck, the lines are capped at two, and iteration order is
fixed so the tooltip is stable across hovers.
