/* ─────────────────────────────────────────────────────────────────────────
   publications.css — page-local styles for /publications.html ONLY.

   This file is intentionally narrow: it carries the filter bar, the
   publication list / venue tiles / citation badges, the metrics stamp,
   the RSS subscribe pill, and the small homepage-pub-list helpers
   (.pub-item, .cite-panel*, .pub-abstract, .pub-links svg sizing) used by
   /index.html. Every other concern — typography, body, links, the
   <header class="nav">, <footer class="coda">, the dossier (.ldos-*)
   manifest header — is owned by styles.css.

   Past versions of this file redefined nav, body, .container, .btn,
   :root tokens, and the entire design system in parallel; that was
   ripped out during the publications-page dossier rebuild to stop the
   navbar from visually drifting on this page. If you need a global
   token, add it to styles.css's :root.
