/* Serge · secciones de la portada después de la tablet.
   Todo el color sale de los tokens de theme.css. Un solo ritmo: secciones a la
   misma distancia, títulos en la misma escala, tarjetas con el mismo borde y
   el mismo radio. Movimiento mínimo: aparición suave al entrar y dos escenas
   que siguen al scroll (convergencia y ruta), nunca en bucle. Sin la clase
   .motion todo se ve en su estado final. */
