   Comparte identidad con la landing del producto (`landing-app/`): misma base
   oceánica casi negra y los mismos acentos luminosos. Lo propio de acá es la
   **constelación**: los productos como nodos de un árbol por el que circula
   energía. Es el gesto de la marca — sistemas conectados, no piezas sueltas.
