Private: the YAML text is parsed in your browser and is not uploaded.
Supported: simple maps, nested objects, lists, quoted strings, booleans, null, numbers, and inline arrays/objects.
Not a full YAML engine: anchors, aliases, tags, block strings, and multi-document YAML are intentionally rejected with a clear error.

Clear limits
Advanced YAML features such as anchors, aliases, tags, multi-document files, and block strings are rejected with an explanation.
