   Manager-primary. Citizen surfaces rarely need breadcrumbs; if
   they do, use the same markup with .u-breadcrumb--cit.

   Composition:
     <nav class="u-breadcrumb" aria-label="Útvonal">
       <ol class="u-breadcrumb__list">
         <li class="u-breadcrumb__item"><a class="u-breadcrumb__link" href="…">Áttekintés</a></li>
