/* ----- HEADER OVERRIDE FOR INTERSTATE PAGES -----
   The global .header is position:fixed with a transparent background.
   It's designed to overlay a dark hero (white text on dark). On
   interstate pages the first thing under the header is the Interstate
   sub-nav, which is dark — so the header reads correctly. But there is
   no global dark hero behind the header above the sub-nav, so we force
   the header itself to have a dark background while in the Interstate
   ecosystem. Adds a navy gradient surface and a subtle blur so the
   white nav text is always readable. */

   Sits directly under the global Header.astro (80px tall). Sticky on
   scroll so users can hop between the 5 interstate pages from any
   scroll position. The dark navy bar with teal active state is a
   deliberate visual cue that the user is "in" the Interstate ecosystem.
