   Sitio de una sola página. Sin preprocesador ni dependencias: se edita
   este archivo y listo.

   CÓMO ESTÁ ORGANIZADO
     01 · Tokens de diseño
     02 · Reinicio y base
     03 · Navegación
     04 · Portada (hero)
     05 · Demo del sistema
     06 · Franja de datos
     07 · Secciones de contenido
     08 · Estimador de proyecto
     09 · Preguntas frecuentes
     10 · Llamada a la acción y contacto
     11 · Elementos flotantes y pie
     12 · Animaciones, responsive y accesibilidad

   CONVENCIONES
     · Los colores no se escriben a mano: salen de los tokens de la
       sección 01, para que el tema claro y el oscuro cambien juntos.
     · Cada componente lleva su propio bloque; el responsive va agrupado
       al final, en la sección 12, y no repartido por el archivo.
