/* Desktop: .header-actions is a real flex container that grows to fill
   the remaining header width (flex:1). .main-nav sits at its start and
   .header-cta (margin-left:auto) is pushed to the far right — visually
   identical to the old display:contents approach, but without it.
   We avoid display:contents here on purpose: Firefox has long-standing
   bugs where flex items inside a display:contents wrapper get their
   used flex-basis / auto-margin free-space miscalculated, which is what
   produced the huge gap between the logo and the nav. display:contents
   also drops the element from the accessibility tree in some engines.
   A plain nested flex container has no such issues in Chrome, Firefox,
   or Safari. The mobile media query below still overrides display to
   none/flex to turn this into a dropdown panel. */
