Diez primitivas que dan a la landing el "gráfico y movimiento" que pidió la dueña, todas con guarda de prefers-reduced-motion: - FondoPuntos / PatronPuntos — el patrón de puntos del manual - TarjetaSpotlight, TextoDesenfoque, ContadorNumero — realce y reveal - Carrusel — deslizable, con contador, autoplay pausable - Icono, SimboloTresLineas, IlustracionInflexion — línea, sin relleno - FondoFoto — duotono azul/dorado sobre foto useAutoStep en lib/motion.ts comparte la forma del autoplay del carrusel para indicadores de paso que no son carrusel. IlustracionInflexion documenta un detalle que muerde: motion.path aplica su propio andamiaje de dasharray aunque no reciba initial/animate, así que la rama de reduced motion renderiza <path> planos en vez de intentar neutralizar los animados.
