/* =====================================================================
   FIX: site top-header language dropdown (#thLang) would not open.
   Cause: two site stylesheets style .th-lang-drop differently —
   inner-hero.css sets `display:none` and only shows it via
   `.th-lang-drop.open`, but navbar.js adds `.open` to the PARENT
   (.th-lang / #thLang), so that selector never matched and the
   `display:none` overrode top-header.css's visibility-based show rule.
   This additive rule (loaded after the site CSS) forces the list visible
   when the switcher is open. No site files are modified.
   ===================================================================== */
/* Lift the whole top-header (a direct child of <body>) above the navbar.
   The navbar carries a high z-index (up to 9999) which was painting over the
   dropdown; the top-header was only 2000. This puts it — and its dropdown —
   on top. (Top-header sits at the very top and never overlaps page content,
   so a high z-index here is safe.) */
