// Package ecr is the standalone ECR E2E suite: control-plane CRUD over the
// awsgw ECR surface plus the OCI data plane (docker/crane/skopeo push-pull)
// against a running cluster. The data-plane subtests skip when the client
// binary is missing or the registry host does not resolve, so the suite still
// runs its control-plane leg on a bare runner.
