The smartphone header is a deeplink to the home page or sections mosaic of a publication that both maximizes engagement and reinforces a customer's brand identity. This feature is built-in to the Marfeel solution to promote recirculation within a customer's Marfeel PWA (Progressive WebApp). 

When a user accesses a publisher's section mosaic or article details via a deeplink, the header that reinforces a publisher's brand also directs the user back to the sections mosaic when tapped, driving further engagement.
