## Overview

This repository is a staged Kubernetes deployment tutorial for a grade-submission application. Its manifests progress from Pods and Services through Deployments, configuration and secrets, database resources, ingress, and Helm charts. The likely user workflow is portal access followed by API submission and database persistence, but no YAML contents or source excerpts were provided, and the README does not document runtime behavior; those relationships are therefore shown as unverified.
