/* ============================================================
   RUTTENS+ V6 CHROME — scoped header/footer stylesheet
   Added 2026-08-23 to unify the old-generation pages
   (free-tools, insight articles, case pages, track-record)
   with the v6 header/nav/footer used on index.html.

   Every rule is scoped under .site-header / .site-footer so it
   cannot bleed into body content, and every rule explicitly
   resets the properties the legacy css/style.css already
   defines for the reused class names (.nav, .nav-links, .logo,
   .btn, .btn-primary, .footer-grid, .footer-bottom) so nothing
   leaks through from the old stylesheet regardless of load order.
   Colors are hardcoded (not CSS custom properties) to avoid any
   collision with css/style.css's differently-valued --navy/--sky
   variables of the same name.
