/* =====================================================================
   CINEMA — home page stylesheet

   Three modes, chosen before first paint by the boot script:
     html.cx-3d          live WebGL stage, acts pinned while the scene plays
     html.cx-3d.cx-reduced  same stage, no pinning, no motion (cuts only)
     anything else       flat layout: all content, a rendered poster
                         of the model, no WebGL — also the no-JS layout

   Composed for Persian first: text on the right, where the eye starts;
   the object on the left. English mirrors that deliberately.
