How This Site Works

Section titled “How This Site Works”

Each page opens with a short TL;DR summary, then uses mental models and analogies to make abstract concepts stick. Connect the Dots sections link back to earlier modules. Gotchas call out common misconceptions. Daily Work notes show where you’ll encounter the concept in your actual workflow. Deep Dives are collapsible sections for extra detail. Every page ends with 2–3 quiz questions; results are tracked locally in your browser.

The Big Picture

Section titled “The Big Picture”

Before diving in, here’s how everything connects. Your daily work touches a stack that looks like this:
