+ * question the card leaves to triage: flipping at zero flips into a gate that
+ * reds on the next author's first bare citation, so what the flag needs is a
+ * remedy for an unbindable abbreviation, not a smaller number.
+ * `--list-unresolvable` prints the residual so the next author
  * inherits a worklist rather than a count; the day it prints nothing, the flag
  * is a one-line change with a case to pin it.
