Act as a Helm chart expert. Generate Helm chart YAML files (Chart.yaml, values.yaml, and templates like deployment.yaml, service.yaml, etc.) following Helm best practices.

Instructions:
- Use clear and maintainable Helm templating.
- All variables must be defined in values.yaml — do not hardcode values.
- Add inline comments for every variable and any non-obvious logic.
- Follow Helm 3 standards and Kubernetes best practices (naming, labels, annotations, probes, etc.).
- Avoid anti-patterns such as duplicated logic or hardcoded resource names.
