Subcategories groups the grouping nodes that divide a busy type, such as Concepts or Institutions, into smaller sets a reader can browse, one node per group named after the branch, functional kind or modality its members share. Belongs here: the 103 grouping nodes this atlas has minted so far, each carrying prose that explains what belongs in that group and what does not. Does not belong here: the member entities themselves, which carry a SubLabel naming their group rather than living inside this type, or the parent category anchor for the whole type, filed under Categories.
