{{- /*
  Returns true when a page should be described as an article - by Open Graph's og:type
  and article:* tags, and by head/schema-article.html.

  An article lives in a content section. Standalone top-level pages - contact, privacy
  policy, a thank-you page - are regular pages, and describing them as articles is
  metadata that does not match the content. Set `schemaArticle` in front matter to
  force it either way.

  One partial rather than the same condition in two templates, so og:type and the
  Article schema can never disagree about what a page is.
