/* ==========================================================================
   Lueri International — site header (mobile-first)  ·  assets/header.css
   Replaces the stacked override layers in assets/mobile-header.css and the
   header blocks at the end of assets/site.css for pages using <header class="lh">.

   Why this doesn't fight the old CSS: every element uses NEW class names
   (lh-*). The old rules target .navbar / .brand / .nav-controls / .nav-cta,
   so none of them match. No !important anywhere in this file.

   Load order:  site.css  →  header.css  (after site.css, before page CSS)
