/* Rocapia — /eficiencia-operativa
   Estilos exclusivos de esta página. Se cargan después de styles.css y son
   puramente aditivos: no redefinen tokens ni componentes globales, solo los
   reutilizan (rc-eyebrow, rc-btn-primary/secondary, rc-tabs/rc-tab-btn,
   rc-sistema/rc-fugas/rc-fuga, rc-metodo, rc-cta-final, wrap, reveal...).

   Los 4 mockups en design/mockups/ definían su propio lenguaje visual
   (fondo papel + ruido + blobs, paleta esmeralda/arcilla propia, JetBrains
   Mono). Aquí se reconstruye su lógica de interacción — nodos, tarjeta de
   detalle Hoy/Con Rocapia, selector de vertical, simulador — sobre el
   sistema de diseño real del sitio. Ver css/tokens/colors.css para el único
   color nuevo introducido (--color-clay-600), justificado como extensión
   puntual para la columna "Hoy" de las comparativas. */
