Thanks a lot for your reply.
To be honest I don´t know which solution is better.
At first glance, it seems like #1 is easier to implement and manage, but I don´t know if it would overload the homepage and make it slower. In the end, there would be 4 summary blocks (2 for desktop view and 2 for mobile view).
On the other hand, #2 seems more complicated (at least for me) to manage and make design changes to summary blocks in future.
My impression is that #1 is a better solution, but what would you recommend?
Thanks again for your help.
