### Docker Standards
- Always use multi-stage builds to separate build dependencies from the final production runtime image.
- Final images must use distroless (gcr.io/distroless/static) or Alpine bases to minimize vulnerability surface and image size.
- Never run containers as root (USER 10001:10001).
- Use .dockerignore to exclude node_modules, .git, and secrets.
### Kubernetes Manifests
- Every container must define livenessProbe and readinessProbe endpoints.
- Always set explicit resources.requests and resources.limits for CPU and memory to prevent noisy neighbor starvation and OOM kills.Zero-cost abstractions, fearless concurrency, idiomatic error handling with anyhow/thiserror.
