/* ================================================================
   Trip Builder page (/trip-builder) — one hero, two audiences: a "Khách lẻ"
   (B2C lead form, TripInquiryForm) and "Doanh nghiệp" (the B2BRequestWizard
   also mounted at /khach-doan; see corporate-events.css for the wizard's own
   styles — this file only owns the page's hero + the tab shell around both
   panels). Signature: the wizard's 5 real steps previewed as stops on a
   dashed route line — a travel-company way to say "here's the journey your
   request takes," using the site's existing ruler-tick eyebrow device. The
   route preview only makes sense for the B2B tab, so it's hidden on B2C.
