Reviewed four never-reviewed reference cards (`cluster`, `ntfy`, `tempo`, `alloy`) and corrected drift: minikube is now Kubernetes v1.35.0; ntfy, tempo, and alloy-k8s images are now locally-built `registry.ops.eblu.me/blumeops/*` nix containers (v2.19.2, v2.10.3, v1.16.0) rather than upstream Docker Hub; the Fly.io alloy binary is v1.16.1; and the ringtail workload list reflects the in-progress minikube→k3s migration.
