/* ============================================================
   HEADER FIX (2026-05-30): the separate .mobile-menu element had
   its hide/position rules only inside @media(max-width:900px), so
   on desktop (and 900-992px) it rendered as a static block under
   the header (the "kayık ikinci nav satırı"). Hide it everywhere
   by default and reveal it only under the navfix 992px breakpoint.
   This block is last so it overrides the earlier media query.
