/* ---------- Services, chapter 2: Freight Services (#freight) ----------
   The light sky of Our Services: the heading, the Sea / Land / Air selector, one large photographic panel whose
   three slides it chooses between (js/freight.js), and the cargo types beneath. With motion it is a view of the
