   ARQUITECTURA (para evitar choques de especificidad):
   1. El orden de precedencia lo define @layer, no la especificidad.
      reset < base < layout < components < sections < responsive
   2. Todo se estiliza con UNA sola clase (BEM: .bloque__elemento--modificador).
      No hay selectores descendientes (.hero p, .cta .wrap, etc.).
   3. Las variantes de botón y de eyebrow cambian variables/propiedades por
      modificador, así :hover y los modificadores no se pisan entre sí.
