   Business Services V2 - "the turning cube"
   Markup:  Views/Home/homePartialsV2/_buisnessServicesV2.cshtml
   Script:  Content/js/UI-interaction/pio-business-cube.js
   --------------------------------------------------------------------------
   Everything is namespaced under .pio-biz so nothing here can reach the
   original section (_buisnessServices.cshtml / pio-swiper), and nothing in
   style.css aimed at swiper-container can reach this one.

   The cube is plain CSS 3D - no Swiper. Four side faces carry the three
   service illustrations (the script re-paints the face that is hidden behind
   the cube, so the sequence reads 1,2,3,1,2,3 forever), plus a brand lid.
   Direction is logical: in RTL the cube turns the other way, so the next
   face always arrives from the reading direction.
