/* ===========================================================================
   CSMC app shell — the chrome every app wears.

   NOT specific to Special Loans. In production a user switches apps via the
   waffle in the top-left; each app drops its own nav items and content into
   this same frame. Keep app-specific styling in the prototype, not in here.

   Deliberately LIGHT, unlike the navy .sidebar in design-system.css. That one
   suits a reporting surface; this suits a working tool you sit in all day —
   closer to Linear or Asana. Both draw from the same tokens.

   Layout:   topbar across the top
             nav (230px) | main | properties (340px, optional)

   340px matches Moonshot/designs/deal-workspace.html so this shell and the
   existing mockups agree rather than nearly agreeing.
