A step-by-step, runnable migration of a service from per-service Helm charts to a shared values-only golden-path chart. Format borrowed from kubernetes-the-hard-way — labs you can git clone and follow on a fresh laptop, not a tutorial you read once and close. Built from the actual migration of 23 packages and 12 weeks of latent-bug surfacing. It lands here when Lab 00 and Lab 01 work end-to-end on a fresh kind cluster.
