lol you are absolutely right, the graphic is really the bit that counts and I made a note directly under it advising that the giant wall of text under it isn't a necessity if the graphic gives you what you need. Will most likely chop the post up into a short one with just the graphic and move the text wall somewhere else. As to why there is a wall of text that is a wall of text in itself.
For what it's worth, the wall of text is extremely helpful. I, for one, learn mostly by text and whether or not an LLM generated this, the output is true it is well written and easy to follow. So long as it's also true I'm satisfied.
It's about as accurate as I can make it, it's been revised with input from the crew over at r/lisp and I've verified what I can. Note the real value is simply in the mapping of the layers of the whole CL tooling stack, and how they fit together. That's what made things click for me.
