Environment Overlays

Overlays contain environment-specific differences.

Required shape:

overlays/<env>/
├── kustomization.yaml
├── app/
├── managing/
└── plugins/

Rules:

Overlay packages reuse base packages.
Overlay packages contain patches, generated config, or environment-specific resources only.
Do not duplicate base package composition in overlays.
A workload override belongs at overlays/<env>/app/units/<unit>/<domain>/<workload-kind>/<workload>/.
