Metadata in a single MD file for multiple terms

[jchytry]

There is only a single taxonomy categories on my website. It has a general layout categories/taxonomy.html, regardless of the term. I cannot find the way to do the same thing with the metadata, so that I have a single markdown file with the front matter defining general metadata for all terms. Something like content/categories/_index.md.

For example, I need this for a (bootstrap-like) jumbotron image, whose path I define in the front matter in markdown files, and here, I want to have it the same for all term pages.

Data that is the same for all terms belongs in the taxonomy front matter… you just need to get it.

  {{ range .Pages }}
    <h2><a href="{{ .RelPermalink }}">{{ .LinkTitle }}</a></h2>
  {{ end }}
{{ end }}

Taxonomy is the parent of terms. Of course, that could have crossed my mind. Thanks!
