/* ============================================================================
   NexusCore Operations — Application Shell
   ----------------------------------------------------------------------------
   A fixed sidebar for navigation, a top bar for scope and identity.

   The important idea: PRODUCT IS A SCOPE, NOT A NAV ITEM. Navigation lists
   functions (Overview, Support, Customers, Products, Reports) and stays the
   same length forever; the product selector in the top bar narrows every
   surface at once. The previous build put "Managed Websites" — a product — in
   the nav as a peer of "Customers" — a dimension, which meant nav would grow
   by one entry for every product ever added.

   Depends on tokens.css and system.css.
