description: >-
  Installs istio/base + istio/istiod, enables mesh injection, deploys the product chart with scope.enabled=true, creates a PeerAuthentication with mode=STRICT in the product namespace, and verifies: (a) plain HTTP from a non-mesh pod is rejected, (b) in-mesh probe pod still reaches the product Service with 200 via auto-upgraded mTLS.
