Beta-blocker contraindications

Declined, deliberately, for this concept: the entries on this list split into three genuinely different bins (absolute stop, caution-and-monitor, and — for stable HFrEF — actually an indication), and the whole teaching point is learning to sort a new, unseen patient into the correct bin by reading severity, timing and sequencing in the vignette. A single memory acronym across all three bins would either flatten that distinction into equal-looking letters (making diabetes and asthma-with-active-bronchospasm look like the same kind of fact, which is exactly the trap this concept exists to prevent) or would only cover one bin and imply the other two don't exist. The discriminators and transferStrategy fields above carry this concept's real teaching weight instead.
