/* ==========================================================================
   SIGMA v2 header: "the command island"
   At rest the header dissolves into the page: a refined light utility line and an airy,
   borderless navigation row. On scroll (header.js adds .is-scrolled) the row condenses into a
   floating glass island: the logo reduces to the sigma mark, search becomes a round icon, the CTA
   becomes a compact pill with its arrow nested in a circle. A soft highlight pill glides between
   links (the classic ink element) and rests on the current page. Mega menus drop as floating
   double-bezel glass sheets with one accent and a quick stagger. Mobile: a compact floating pill
   and a full-screen light glass menu. All behaviour stays in js/header.js; this is styling only.
