## Source (`kind` YAML, verbatim)

```yaml
# yaml-language-server: $schema=../schema/kind.schema.json
# Another Zeema design placed in this one as one box: a system drawn elsewhere, named here by
# the node's `ref` (owner/slug pinned to a release). Category `external`: no rule selects by that
# category alone, so nothing judges this box, and nothing should: what it is lives in the other
# design, and rules never cross designs. It has no properties for the same reason; the reference
# is the node's `ref` field, not a property. The "no rule" gap is recorded in docs/schema-gaps.md.
