* Usage
You must compile the tachyons modifications.
For that run the local makefile for the =css= target.

It is only a dev dependency, there is no need for tachyons dependencies on the
project.
* Design decisions
** Authors
=ox-hugo= exports from the =author= front matter regardless of it allowing
multiple items. It seems to prefer that and hints in this page, how to use the
plural.

I however find the plural =authors= consistent to the field accepting a list.
Secondly, it plays correctly with taxonomies which activate with the
singular=plural key=value. Thus be consistent on that and use the ox-hugo
replacing workaround.
