Starting out

Run these commands in a directory devoted to your project:

mkdir project_foo
cd project_foo
git clone --bare git@github.com:yourorg/project_foo.git .bare
echo "gitdir: ./.bare" > .git

Now edit .bare/config, adding fetch = +refs/heads/*:refs/remotes/origin/* below [remote "origin"]

jquery.scrollLock.js

Useful for when a blocking user experience is needed (in my case, didn't want people unwittingly loosing their place by scrolling while a modal required their attention): $.scrollLock() locks the body in place, preventing scroll until it is unlocked.
