Subject: [PATCH] =?UTF-8?q?feat(primitivas):=20capa=20gr=C3=A1fica=20y=20d?=
 =?UTF-8?q?e=20movimiento=20reutilizable?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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.
