{{- /*
  In-cluster Redis, mirroring how the chart bundles PostgreSQL so a default
  install has the same capabilities as the Docker Compose stack. Redis backs
  pub/sub, the Socket.IO adapter, and the idempotency and progress stores;
  without it, multi-replica deployments silently drop cross-pod events.

  No persistence: Sim uses Redis for coordination and short-lived keys only,
  and losing it costs in-flight live updates, not committed data. For
  production, prefer a managed instance — set redis.enabled=false and point
  app.env.REDIS_URL at it.
