/* IDMA Security · componente "Modelo de referencia" (Como operamos).
   Replica el componente de NEXAKON (seguridad.html: .seq-wrap, .dd, .seq-video) con los tokens de IDMA.
   Color de acento: el azul de IDMA queda en el eyebrow y el segmento resaltado del titular (reglas globales, .eb y em);
   el naranja de los botones se usa solo en los estados interactivos: borde del selector abierto, opcion activa y etiqueta del video. */
