   Página de lectura — combina:
   · Duolingo: botones redondeados con "relieve" inferior, barra de progreso dorada,
     capítulos recorridos en verde, tipografía amigable (Nunito).
   · Bible.com: columna de lectura limpia y centrada, texto serif cómodo,
     barra de lectura con capítulo/página, ajustes de tamaño y tema.
   Azul = marca y confianza; naranja/dorado (el de la barra de navegación) = progreso y logros.
