/* ==========================================================================
   T175 — current-page header-nav highlight (class: iv-current)
   --------------------------------------------------------------------------
   The class is emitted server-side by Models\HeaderNav.cs from the current
   controller/action (see Views\Shared\_Layout.cshtml, both nav copies).

   iv-current is DELIBERATELY distinct from the theme's th-active, which is the
   mobile accordion open/closed state written by thmobilemenu — never reuse it.
   Marking a parent iv-current is styling only; it does NOT open the accordion.

   The vendor assets\css\style.css is never edited; everything lives here.
   Colours come from the theme's own --theme-color / --title-color variables.
