   Compartido por el panel staff (crm.html) y el portal del cliente
   (dashboard.html, en/dashboard.html): ambas vistas tienen que sentirse el
   mismo drive, así que los estilos viven acá una sola vez en vez de
   duplicados en crm.css y dashboard.css.

   Requiere design-tokens.css (lo importa styles.css) para los tokens de
   color, radio y sombra, incluido el dark mode vía [data-theme="dark"].

   DOCUMENTOS — SHELL TIPO DRIVE (dos paneles)
   Carpetas fijas a la izquierda, archivos a la derecha. Todo el color sale
   de tokens (--card/--border/--text/--muted/--color-*) para que la sección
   funcione igual en claro y en oscuro: los chips viejos tenían colores
   hardcodeados y en dark mode quedaban ilegibles.
