/* Removed: the former `.language-switch-container` / `.selected-language` rules
   targeted an older language-switcher markup that no longer exists (current markup
   is `.language-switcher-language-url` + `#languages-menu`, see
   templates/region/header-slim-language/links--language-block.html.twig). They
   matched nothing and were dead weight. Toggle/dropdown styling now comes from
   Bootstrap Italia defaults. */
