/* ============================================================
   OZI Technology — multi-page header additions

   The bulk of the navbar / dropdown / mobile-menu styling already
   lives in site.css and is reused as-is. This file adds only what
   the multi-page split needs:
     1. active-page highlighting
     2. the theme toggle (lifted out of the home page's inline <style>
        so every page gets it)
     3. a wider mobile breakpoint fix for the accordion
   Brand accent: --ozi-blue-green-500 (#1C99BF).
