    "incantation": "When releases share templates, set top-level `defaultInherit` in `helmfile.yaml` to a template name or ordered list; Helmfile applies them to every release and does not duplicate templates already explicitly inherited. Use release `inherit[].except` to omit fields.",

      "templates:\n  defaults:\n    namespace: kube-system\ndefaultInherit: defaults\nreleases:\n- name: <release-name>\n  chart: <chart>\n  version: <version>",
