Production Solution & Architecture
Three levels: Privileged (no restrictions), Baseline (blocks most dangerous capabilities — no privileged, no hostPath), Restricted (most secure — non-root, no capabilities, seccomp required). Apply per-namespace with PodSecurityAdmission: pod-security.kubernetes.io/enforce: restricted label on the namespace.
