Blood-type compatibility API

Resolve ABO/Rh red-cell transfusion compatibility for a donor and/or recipient: which types they can donate to, which they can receive from, the donor-to-recipient verdict, and universal-donor (O-) / universal-recipient (AB+) flags — the value-add being the antigen-based compatibility logic LLMs get backwards. Answers 'can O- donate to A+', 'who can receive AB+ blood', 'is this donor-recipient pair compatible', 'is O- a universal donor'.
