/* ---------- Hero visual: node spokes drift (sway) + presence (aparecen/desaparecen) ----------
   8 nodos a distintas distancias y ángulos del centro (radios 58-90, repartidos
   alrededor del círculo). Cada uno combina un sway (rotación, tres curvas distintas,
   normal o reverse) con una animación de presencia (opacity) independiente y
   desincronizada (duración y delay distintos por nodo) — así el número de nodos
   visibles en un momento dado sube y baja, en vez de los 4 moviéndose parejo de
   lado a lado. Algunos nodos son "active" (línea sólida, punto relleno) y otros
   "dim"/"dim2" (línea punteada, punto solo contorno, trazos de distinto largo). */
