   PAMEH · Shell layout  (rediseno estructural del chrome)
   ----------------------------------------------------------------------------
   Reemplaza el rol de layout de la plantilla Blankon para el "chrome":
   topbar unificada + rail de navegacion colapsable + page-header + footer.
   Se carga DESPUES de pameh-modern-ui.css. Usa clases propias `shell-*` /
   `rail-*` / `page-*`; no depende del DOM Blankon (#header, #sidebar-left...).
   Paleta institucional SEFIN: azul #19438c - blanco - dorado #ad8411.
