   Three-column layout using a single flex row that slides
   via transform: translateX(). All three panels move as one
   unit, guaranteeing they never overlap.

   Normal mode (translateX(0)):
     Viewport shows [Eco 85vw][Mgmt 15vw]

   Viz mode (translateX(-80vw)):
     Viewport shows [5vw eco strip][Mgmt 15vw][Viz 80vw]
