Case contract

Input: {"hand": class such as "AKs", "AKo", "AK" or "QQ", "dead": [known cards, rank upper-case or lower-case, suit lower-case or upper-case]}. Enumerate the concrete two-card combos of the class (suits c,d,h,s) and return how many contain no dead card.

Why this case matters

Blocker math decides how many value combos an opponent can still hold.
