/* The scrolled blur/tint lives on a pseudo-element, not on .site-header
   itself. backdrop-filter (like filter/transform) makes the element that
   carries it a new containing block for ITS OWN position:fixed descendants
   — and .nav-list (the full-screen mobile menu, position:fixed; inset:0)
   is exactly such a descendant. With backdrop-filter on .site-header
   directly, .nav-list stopped covering the viewport and instead sized
   itself to .site-header's own ~80px box the moment .is-scrolled landed —
   the mobile menu links rendered squeezed into a thin strip instead of a
   full-screen overlay. Moving the effect to ::before sidesteps this
   entirely: the pseudo-element still paints the same blurred bar, but it
   isn't itself a fixed-position ancestor of .nav-list. */
