/* ==========================================================================
   Glossary — a laboratory that publishes an A-Z of the words on its labels.

   The signature device is the lettered term index and the definition entry,
   each of which carries a "what it does not mean" counterpoint. The homepage
   states the business before the index starts. No contents rail, no
   directory board, no parameter strip, no calendar grid, no photography.
