Dashboard using new Sections (experimental)... how to handle portrait / landscape

I am switching over to the new Sections (experimental) dashboards. I am replacing manual / all custom button card dashboards that are hard to maintain.

I have some Samsung A8 tablets around the house, some landscape and some in portrait orientation. With my current custom dashboards they are hand crafted to look good in either landscape or portrait tablet orientation. In fact they are two different dashboards which makes it even harder to maintain.

My question is how people are handling this with the new Sections (experimental) dashboards? I design a new dashboard for landscape but when it is displayed on a portrait tablet it does not flow correctly. All the content is there of course. I think I need a way to order the cards differently based on the portrait / landscape orientation of the tablet.

Thanks for any guidance.
