If you work in terminals, try this exercise: choose three signals you truly need to notice in the next week. Create three highlight rules in Xshell—one color per signal—use them for a few days, then prune. You’ll learn, quickly, which colors you trust and which become wallpaper. That small experiment captures the essence of the chronicle: attention guided by restraint, color as a tool, and the gentle craft of tuning a tool until it feels like an extension of your mind.
