   MENÚ LATERAL (SIDEBAR)
   ========================
   Importante: dejamos que AdminLTE maneje todos los
   estilos del menú lateral para conservar el look
   & feel ORIGINAL del tema.

   Por eso se eliminaron aquí los overrides sobre:
   - .main-sidebar
   - .sidebar-menu
   - .sidebar-menu .treeview-menu

   Si en el futuro se quiere personalizar el menú,
   crear una hoja de estilos aparte que no reemplace
   los estilos base de AdminLTE.
