/* ── PORTED NAV ──────────────────────────────────────────
   Resources is a top-level nav destination but is served by legal.css,
   which never loaded the nav rules — so the page had no navigation and no
   hamburger at all. Lifted verbatim from components.css, with the two font
   tokens inlined because legal.css does not define --font-display/--font-body.
   Keep in sync with components.css if the nav changes there.
