/* ---- rn-foot v2 (owner request 2026-09-20): the Regulatory News footer.
   One stylesheet, loaded from templates/footer.html, so every page (articles, hubs, hand pages, the
   front page) takes the same footer from one source. It sits on top of the older footer rules in
   news.css / article.css / the shell, which is why every selector starts `footer.rnf`.
   Four bands: the Briefing sign-up, the link groups, how we report, and the signature + legal row.
   Phones: the link groups are laid out by the estate-foot block (owner ruling 2026-09-16, a
   two-column ledger with !important throughout), so the grid rules here start at 769px and only
   the bands this file adds are styled below that. ---- */
