/* =========================================
   PLATFORM NAVBAR — legacy styles for the platform admin layout.
   The platform navbar (app/views/platform/_navbar.html.erb) still uses
   the old ctx-card/ctx-slot/nav-link pattern. These styles are preserved
   here so the platform admin UI continues working after the main navbar
   was rewritten to the dark theme in Epic 0004 Phase 1.
   ========================================= */

   theme back to a light gradient for the platform surface. */
