What a human-facing card or footnote shows under a header that already
names the id: the definition minus its defining marker — and for
decisions, just the **Choice:** line (the decision in force; the
Rejected/Consequences argument stays behind the click-through). Falls
back to the full block body when no Choice bullet exists. Derived by
elision only — never rewording.
Verbatim definition block: the heading or list item through the end of its body. A requirement's block stops before its acceptance-criteria list — criteria are first-class entries of their own, and a card that repeats them renders the same content twice.
