Convert configuration between JSON and YAML for Kubernetes manifests, CI pipelines, Docker Compose files, and OpenAPI specs. The YAML parser is intentionally minimal: it handles plain maps, lists, nested blocks, quoted and plain scalars, inline JSON-style flow values, and comments. It does not support anchors/aliases, custom tags, multi-line block scalars (| and >), or multi-document streams — for those, use a full YAML library.
