HelmRelease.spec.valuesFrom[].literal

Literal marks this ValuesReference as a literal value. When set in combination with TargetPath, the referenced value is merged at the target path without interpreting Helm's `--set` syntax (commas, brackets, dots, equal signs, etc.), mirroring the behavior of `helm --set-literal`. This is the only safe way to inject arbitrary file content (config files, JSON blobs, multi-line strings containing special characters) through `valuesFrom`. Has no effect when TargetPath is empty: in that mode the referenced value is always YAML-merged at the root.
