№ 02 — the method
See it, then use it.
Why animation, and not another stack of slides.
Every one of these subjects is mostly invisible. A commit graph rewriting itself, the moment one class quietly takes on a second job, the dependency that points the wrong way — none of it is something you can point at on screen. The usual course describes it in prose and hopes the picture forms. These draw the picture.
01Animated, not illustrated — the diagram moves because the thing it stands for moves. You watch a rebase replay commit by commit instead of reading a paragraph about what rebase does.
02Internals first — objects and refs before commands; the problem before the pattern that answers it. Once you can see the machine, its moves stop being spells to memorize.
03Nothing skipped — the awkward middle, where most courses thin out to a link and a shrug, is the part worth paying for. It gets the most time, not the least.
