Rationale

Detector age is the #1 buying-decision driver — capture it in frontmatter so the site can highlight systems with fresh panels. Tomo + C-View licensing are separate from hardware and often left off listings; the schema forces disclosure. MQSA flag matters because any mammo unit that can't pass physicist testing is not clinically deployable.
