 La pantalla `CompanyOverview` tiene composición independiente de `DashboardPage` (Inicio). Comparte tarjetas, bloques de trabajo/avisos/actividad y consultas existentes, siempre fijando el ámbito al UUID de la compañía. El encabezado «De un vistazo» precede las acciones rápidas (ticket, intervención, activo y recurso), cuatro indicadores operativos y una franja navegable de personas, departamentos y sedes. No muestra compañías activas ni el resumen por compañías. La variante compacta de `StatisticCard` mejora la jerarquía del valor y la etiqueta sin modificar la presentación de Inicio.
 
 La navegación de compañía empieza por Resumen, Tickets e Intervenciones; después agrupa Personas, Puestos de trabajo y Perfiles de usuario y finalmente las demás secciones. Los grupos tienen separación visual. Las operaciones de usuario permanecen en el menú superior y dejan de repetirse al pie del menú de compañía.
+
+## Fichas de consulta y resumen lateral
+
+Las secciones de consulta evitan recuadros anidados y rellenos laterales: usan títulos compactos y un separador tenue entre grupos. Las agrupaciones de características siguen este mismo criterio en lectura; los formularios conservan su organización propia.
+
+`DetailSection` ofrece agrupación plegable nativa (`details/summary`), abierta inicialmente, accesible por teclado. `DetailField` devuelve una fila semántica `dt/dd` para incluir en un `dl`: etiqueta y valor se alinean horizontalmente cuando el contenedor dispone de al menos 240 px y se apilan en espacios menores. El consumidor aporta los enlaces; el componente común les aplica cursor de enlace, color semántico y subrayado al pasar el puntero. Los valores ausentes permanecen como texto.
+
+La ficha lateral de activos utiliza un ancho adaptable entre 320 y 400 px, acciones debajo del título y bloques de identificación, ubicación/asignación, características, observaciones, relaciones y asistencia. Conserva las secciones capturadas de la plantilla, incluyendo la compatibilidad con especificaciones antiguas sin agrupación; no modifica valores ni instantáneas. Las relaciones llevan a destinos existentes: persona y activo relacionado a su ficha; sede, puesto y plantilla a sus listados/catálogos actuales. La vista completa e historial mantienen sus funciones. Las fichas de recursos reutilizan las filas de características. No se crean nuevas fichas laterales ni nuevas rutas.
