/* ==========================================================================
   S4 · THE FOLIO RAIL
   --------------------------------------------------------------------------
   The Figma Make exploration supplied one useful structural idea: persistent
   navigation at the left edge. The exploration's visual system is not
   imported. The top bar switches products; this rail shows the real workflow
   inside the current product, using Conxfolio's existing visual system.

   Public home: unchanged. Mobile/tablet: unchanged. Context panels: unchanged.
   At desktop widths the repeated top product switcher steps aside and this one
   rail becomes the product-level navigation.
