"panel 1: HEAD is a tiny file containing the name of the current branch
(diagram)
panel 2: when you commit, git updates the current branch to point at the new commit
(more diagrams)
panel 3: SO MANY things in git use the current branch
* git commit moves it forward
* git merge merges into it
* git rebase copies commits from it
* git push and git pull sync it with a remote
panel 4: many git disasters are caused by accidentally running a command while on the wrong branch
person: "git commit"
person: "UGH I didn't mean to do that on main"
panel 5: I keep my current branch in my shell prompt
to me it's as important as knowing what directory I'm in
panel 6:
julia: "I think HEAD is a weird name for the current branch (why not CURRENT or something?) but we're stuck with it""
