   ShellV4 — estilos del nuevo shell. TODO aislado bajo .ns-shellv4.
   No toca app.css ni clases ns-* existentes. Colores/medidas/radios fieles al
   prototipo docs/nanchesoft-shell-lite.html. Modo claro/oscuro vía [data-theme],
   densidad vía [data-density] (los pone el layout en el contenedor .ns-shellv4).
   Las variables --brand1/--brand2 las escribe nsShellV4.applyTheme().
