Total number of fence lines (``` openers/closers) in a document. A BALANCED
article has an EVEN count; an odd count means a fence was opened and never
closed, which leaves every fence-aware scanner (this module, vault.ts,
normalize.ts, crosslink.ts) stuck "inside a code block" for the rest of the
file — so trailing real sections (## References / ## See also) are read as
code and never recognized.
