Translate YAML mappings, sequences, and JSON-compatible scalars into strict JSON without uploading the source document.

Strict, bounded, local processing
JSON has a narrower data model than YAML. Conversion must reject or report unsupported keys, tags, non-finite numbers, aliases, and other values rather than silently inventing a mapping.
JSON objects require string member names and JSON values are limited to objects, arrays, strings, finite numbers, booleans, and null. A converter should expose any YAML construct that cannot cross that boundary predictably.
The output is strict, indented JSON suitable for review. Mapping and sequence order remain stable, while comments and YAML presentation details are not part of the JSON result.
Plain scalars can look like booleans, numbers, dates, or identifiers. Test representative values such as leading-zero codes and timestamp-like strings against the same YAML version and schema used by the consuming system.
