We use a custom style block in the base that defaults to ISEAL, but
gets overridden in the FSC layout. Layout is determined in the term
frontmatter, either "home" or "fsc".
After running the util/generate_docs.py script to parse and extract
the metadata term specifications and their controlled vocabularies,
we use Hugo to generate the HTML site. The HTML site uses Bootstrap
with several ISEAL brand colors gleaned from the corporate website.
