This environment variable specifies a region substitution to apply when constructing GCS bucket paths during recovery. It is injected into the HumioCluster pod spec as an extraEnvVar by Terraform when var.dr != "" and is preserved across both standby and active DR modes to prevent pod recreation during promotion.

Note that GCP_RECOVER_FROM_REGION is not used for GCS recovery. LogScale ignores the region parameter for GCS because GCS bucket access is not region-scoped the way S3 is.
