/* One header for the landing page and the guides: logo, the page's sections
   (landing page only), language, one call to action, and a reading-progress
   bar along its top edge. Behaviour: /header.js. Like /footer.css, every rule
   is scoped under .careers-header so it outranks each page's bare element
   rules whatever order the sheets load in.

   Two placements:
   - default (guides): sticky in the flow, solid navy over the navy hero;
   - .is-overlay (landing page): fixed, frosted navy; transparent while the
     page is at the top (.is-top). The page reserves --ch-h of room for it. */
