  % \ntindex{text} (no brackets).  Instead grab everything up to the mandatory
  % brace group (nothing, or "[key]") and discard it, then emit the mandatory
  % argument.  This is fully expandable, so it works inside \pdfstringdef (where

  % Fix duplicate PDF destinations across main matter and appendices.
  % Hyperref's \theHchapter defaults to \arabic{chapter}, which resets to 0
  % when \appendix is called.  Appendix B therefore gets the same raw counter
  % value (2) as main chapter 2, producing clashing anchor names like
  % "table.2.1".  Redefining \theHchapter to use \thechapter (which gives
  % letters in appendices: A, B, C …) makes every anchor globally unique.
  \renewcommand { \theHchapter } { \thechapter }
