/* Glossary page - one reading column with a search box, a sticky row of
   category chips (the current one is marked as you scroll), and terms you can
   link to (the # beside a name). Search is client-side over content that is
   otherwise reorganised copy already written elsewhere on the site (tooltips,
   CHECK_EXPLAINERS, footnotes). The type follows the site: one sans, tight
   tracking on titles, a secondary grey for explanations. */
