   nisto-hub.css — Hub de Actividades (Conversaciones · Procedimientos · Seguimientos)

   Componentes REUTILIZABLES por las tres sub-vistas (SDD "Hub Actividades" §2-§10):
     .hub / .hub-subnav            shell con sub-navegación de 220px (§2)
     .filter-toolbar (.ft-*)       una fila, sin wrap, controles de 34px (§3)
     .hub-kpis                     4 tarjetas (§5; solo Conversaciones)
     .data-table (.dt-*)           tabla densa con acento lateral de 3px (§4)
     .hub-pag (.pg-*)              paginación (§4)
     .dt-state / .skel             vacío · carga (nis-shimmer) · error (§9)
     .wide-panel (.wp-*)           detalle al 70% con velo (§6)
     .sug-bar / .composer          respuesta sugerida + composer (§6.2)
     .hub-m*                       mobile 390: segmented de iconos, tarjetas y detalle (§8)

   Tailwind está PRE-COMPILADO: las utilidades nuevas no existen, por eso el hub vive acá.
   Los 9 tokens nuevos del SDD §11 están en nisto-tokens.css; abajo, alias LOCALES del hub
   (colores del handoff que no tienen token de marca propio).
   OJO: --live (coral) = "En vivo"; --needshelp-accent (ámbar) = fila escalada.
