Frequently asked questions
Which YAML spec?
YAML 1.2 via js-yaml — the same parser Kubernetes tooling uses.
Does it preserve comments?
No. YAML comments are stripped on parse — this is a fundamental YAML → JSON limitation, not tool-specific.
What about YAML tags like !!str?
Standard tags are supported. Custom tags are not resolved and will error.
