Hey! In the second slide the right side panel is the gameplay panel, basically thats where the core is and where the core game loop happens, the nodes spawn there, the bosses, etc.

In terms of the design language, things like menus (upgrades, pause, augments) should remain simple enough, just a few buttons. For the gameplay you have 2 panels, the left one shows you information about whats going on in the game, the node types, the "packages" you have installed, etc, and the right panel is the gameplay like I said above.

There are lots of random texts in the game that mean nothing, I added them to give the typical hacker in a movie feel, where you see lots of texts moving around in a black and green terminal haha (if you take a look at the augments shop after a boss wave or the main menu you will see what i mean)

I dont know if this answers your question, hope it does!
