Done:

• Refactored static, raw Kubernetes infrastructure manifests into an advanced package format using standard Helm Chart specifications (/charts/ecommerce-app).
• Abstracted image definitions, resources boundaries, and application profiles parameters making them dynamic via values.yaml.
• Implemented Environment Parity by introducing a strict production configuration profile file (values-prod.yaml) upgrading running instance counts to 3 replicas.
• Automated chart syntax error validation checking through native helm lint mechanisms.
• Setup local rendering test pipeline in .github/workflows/lab4.yml parsing configuration sets safely via isolated dry-run engine checks.

🚀 Lab 4 Helm Packaging architecture is fully approved and completed!
