{{- /*
  Returns true when a page is an author's own profile page, the thing head/schema-article.html
  links to as an article's author.

  One partial rather than the same condition in three templates, for the same reason
  head/is-article.html exists: og:type, the Article schema and the ProfilePage schema must
  never disagree about what a page is.

  The section is named by `authorSection`, defaulting to "authors", so a site in another
  language can put its author pages under /autores/, /auteurs/, and so on.

  Two page shapes qualify, because the theme supports both:

    Kind=page   a content section of leaf bundles, content/<authorSection>/<slug>/index.md
    Kind=term   a taxonomy, [taxonomies] author = "<authorSection>", where the term page
                takes its metadata from content/<authorSection>/<slug>/_index.md

  Kind is what separates a profile from a listing. `taxonomy` (the /authors/ index) and
  `section` (the /autores/ branch page) both carry the same .Section and are lists of authors
  rather than one author, so they are excluded.

  Worth knowing: a term page has .IsPage false, so head/is-article.html already excluded the
  taxonomy shape before this partial existed. Only the section shape was being described as
  an Article.
