What is Helm Merge?
A Helm-style values merger: combine base and override documents with deep-merge semantics where nested maps merge and scalars/lists are replaced.
How it works
Documents are parsed with js-yaml and merged pairwise with Helm semantics: objects deep-merge, everything else is overwritten by the later document.
