  # Note: we use `fast_generate` here instead of `generate`. They basically act the same, except
  # `generate` includes an extra check for self-referential data structures. `value` here ultimately
  # comes out of a parsed JSON document (e.g. either from an ElasticGraph event at indexing time, or
  # as a GraphQL query variable at search time), and JSON cannot express self-referential data
  # structures, so we do not have to worry about that happening.
  #
  # ...but even if it did, we would get an error either way: `JSON.generate` would raise
  # `JSON::NestingError` whereas `:JSON.fast_generate` would give us a `SystemStackError`.
