   DESIGN PLAN
   Layout : fixed nav rail (evergreen) + sticky topbar + dashboard replica
            (main column + widget rail) + full-width component bays below.
   Color  : --primary  blue, every interactive element in the content area
            --rail-*   deep evergreen, used ONLY by the sidebar so navigation
                       chrome never competes with in-page actions
   Type   : display Outfit / body Plus Jakarta Sans / mono JetBrains Mono
