/* ============================================================
   HAMBURGER MENU — public nav (pure CSS, checkbox trick)

   DOM order inside <header> (public only):
     input.menu-btn           ← off-screen checkbox
     nav
       div.nav-top-row        ← always-visible row (logo + burger)
         div.nav-left         ← logo + desktop link list
         ul.nav-right-links   ← desktop right links
         label.menu-icon      ← burger icon trigger
       ul.nav-mobile-links    ← full dropdown (hidden by default)

   At desktop: .menu-icon and .nav-mobile-links are display:none.
               .nav-top-row is display:contents so its children
               participate directly in nav’s flex row.
   At mobile:  nav becomes a flex column. .nav-top-row is a real
               flex row (logo | burger). .nav-mobile-links expands
               via max-height on checkbox:checked.
