   Motor portado de la web de Alumne Flex (wow.css): escenas fijadas con --p,
   apariciones al entrar y piezas que se encienden por pasos. Encima, los
   componentes nuevos de la home (hero con red neuronal, sección del agente,
   sliders) y de /empresas.

   Contraste (WCAG 2.1 AA), comprobado sobre el peor punto del fondo:

   - #B6BECD sobre #0F172A ................................. 9,9:1
   - Naranja #FF8F3D sobre #0F172A .......................... 7,9:1
   - Texto charcoal sobre botón #FF6A00 ..................... 6,1:1
