   RESPONSIVE.CSS — VIDA Xport
   Mobile-first: main.css define el comportamiento mobile.
   Aquí solo agregamos AJUSTES para pantallas mayores.

   BREAKPOINTS:
     · Tablet:  768px+
     · Desktop: 1024px+
     · Large:   1440px+

   ESTRUCTURA POR FASES:
     · Fase 2A: Header (mostrar nav), Hero (2 columnas),
                Credibilidad (4 columnas), Problema (3 columnas).
     · Fase 2B: Servicios, Proceso, Sobre, Recursos, FAQ, Contacto, Footer.
     · Fase 4:  Hamburguesa mobile + ajustes finos adicionales.
