We use the front matter keywords field to determine related content. To ensure
consistency, during site build we validate each keyword against the entries in
data/keywords.yaml.

As of March 5, 2025, this feature is experimental, pending usability
assessment. We anticipate that the number of additions to data/keywords.yaml
will decrease over time, though the initial implementation will require some
effort.
