/* ==========================================================================
   Kane fleet header — tokens + top navigation bar.
   Copied from the kane-brand kit (reference/kane-tokens.css + kane-nav.css).
   Linked BEFORE styles.css so the app's own tokens still win where they
   overlap; the class names below are the kit contract — do not rename.
   Light mode only (Kane apps ship light-mode only).
