/* Deep Signal header — mobile navigation (burger + slide-down panel).
   Pairs with ds-mobile-nav.js, which tags each Deep Signal nav with the
   stable marker classes .dsm-nav / .dsm-open and injects .ds-nav-burger.
   Deep Signal pages use a per-page prefix (ds-nav, so-nav, …), so the
   links/CTA are matched generically via [class$="-nav-links"] /
   [class$="-nav-cta"]. The in-body node CSS hides the links at <=768px;
   the open-state rules below (higher specificity + !important) reveal them. */
