Namespaces, cgroups, OCI images, container runtimes, Kubernetes scheduling, controllers, networking, and storage. Implement designOutline() returning non-empty values for: isolationPrimitive, desiredState, reconciliation. Each value must name a concrete mechanism or decision.

## The mechanism

A container is an isolated process; Kubernetes is a reconciliation system that continuously drives observed state toward declared state.

## Expected evidence

A design outline with isolationPrimitive, desiredState, reconciliation plus an explicit failure mode or trade-off.

## Hints

- Name the failure mode before selecting the mechanism.
