/* ---- Glossary: stacked definition list (source glossary.html:11-21) ----
   Stacked layout avoids the max-content overflow the two-column .roster grid
   hits on phones when the term is a long phrase. Token mapping per the Plan B
   header above: --hairline → --hair | --muted → --mute | --font-serif →
   --font-display. Source --fs-h4 / --fs-small / --fs-xs are not in the new
   token set; ported as literals (1.3rem / .92rem / .82rem), consistent with
   the .sources / .lede treatments elsewhere in this file. */
