Patch-based, environment-aware K8s deploys with plain YAML and zero templating

Simple: No templates, DSLs, or logic in YAML, zero magic.

Predictable: No string substitutions or regex hacks.

Safe: Only native Kubernetes YAML manifests — readable, valid, untouched.

Layered: Patch logic is externalized and explicit via JSON Patch (RFC 6902).

Declarative: Cross-environment deployment with predictable, understandable changes.
