// serde_yml migrated to noyalib (compat-serde-yaml shim) — closes RUSTSEC-2025-0068.
// Module alias preserves call-site paths byte-for-byte.
// Note: noyalib's Mapping is String-keyed (type-enforced), Number::as_f64 returns f64 directly,
// TaggedValue.value is private (use tagged.value() method).
