Add an initial website based on the arcana template from html5up,
which is CC-BY licensed.
It includes some initial content about Zuul, but is mostly intended
to bootstrap the process of collaboratively editing the site. All
of the content in this repo should generally be CC-BY licensed as
well.
The banner image was created by me in my personal capacity, and it
is also licensed CC-BY.
This includes jobs to publish draft and final versions of the website,
including the production secret needed to publish to afs.
