Post-Hive Buzzed Rant - Mystery Question (Update)

What's with the green text?

(p. 24) I could not feel. I was bright blank inside.

(p. 44) The truth of nothingness, that is despair.

(p. 65) My uses for meaning have somehow died.

(p. 185) And I exist, with the world, without care.

​(p. 207) Those who came before us are lost to us now.

(p. 200) No shadow of thought would be left behind.

(p.269) We lose all we have done and built and how.

(p. 280) What is a moment in the face of time?

(p. 298) Fight or flight or dream: How I can be free?

(p. 386) Hope diminishes in proportion to choice. 

(p.397)  I was as still as I was meant to be.

(p. 404) Safe, holding hands.  Heard, inside a voice.

(p. 434) Fate is time's meaning, measured by the mind.

(infinity) What has always been is hardest to find.

Madison astutely noted that the green M's resemble bats as well as the thread Zeke used to conceal the unopened envelope inside his grandfather's shirt. The seemingly random number of them used at a given time to seems to me to suggest a meaning as well. Andy had an idea about how this whole thing was part of the same 'thread', which I also think is interesting.

Which brings me back to my question: What is with the the green text?

Websleuth Andy did some searching and didn't find any solid discussion of this. Bookclub, you will be the first. Bottoms up!

Update: More green text discovered and added to the quote box (hat-tip: Speed-reader Andy). As I mentioned in the comments, there is a list on page 191. That says "Flag> TEXT FOUND IN DUST." It has lines with typed numbers on the side that so far correspond exactly to the page numbers of the green text quotes in the quote box, and all the lines are blank except for the top one: 24__________ ... where the first quote I COULD NOT FEEL. I WAS BRIGHT BLANK INSIDE. is written in pencil. The handwriting matches Eliza's; it is stamped by Z. Thomas. Recall, that Eliza is a good falsifier.

​The last one, ​"(p. 207) Those who came before us are lost to us now." is preceded by "Zeke though of his grandfather. He wrote in the dirt at his feet. M " That seems consistent with these being messages found in the dust as the list says, but not all are consistent with that. The second one, "(p. 44) The truth of nothingness, that is despair." comes right after a description about how Zeke's grandfather's bookcase was well kept and dusted. So, I dunno.

Update 2: On p. 280, we have an extraordinary example of the green text. Why extraordinary you say? Because it occurs in the caption to The Drawings of Zaddock Thomas. That’s why. All others occurred in The City-State.

​Also, it’s a sonnet.
