Thanks, seeing it in all caps on the screenshot I thought “is this short for Cloud Account?”

I think each mention of the CLOUD Act should have an “ⓘ” link to a site explaining why it’s important. The About page is way too brief about this.

These are such wide categories…

There’s also this option, perhaps for very unbalanced categories

╳┌───────┐
╳│┌───┐╳╳│
╳└┼───┼──┘
╳╳└───┘

Basically the two boxes’ boundaries should cross, not overlap. Unfortunately, that takes away some symmetry and cleanliness. Maybe a symmetrical pair of boxes with chamfers (45° corners) crossing could work?

Otherwise, you need color or shading.
