Core principles

Multi-stage builds always — dev dependencies must not reach production

Non-root user in production — running as root is a container security violation

Layer order matters — most-changing layers last for cache reuse

Health checks in every container — orchestrators need them for traffic routing

Resource limits are mandatory — unbounded containers destabilize the cluster
