/* NEX-629: section navigation on the public landing pages (index, buyers,
   suppliers), driven by public/js/section-rail.js.

   Wide screens get the same dot-and-label rail as the RFQ and quote pages.
   Narrower screens get a chip bar pinned under the sticky header. The switch
   is at 1360px rather than the dashboard's 1280px: landing content runs to
   1040px wide, and at 1280px the rail's labels would reach into it. */
