+# Terraform script to create test secrets across 3 Azure KeyVaults
+#
+# Creates:
+#   - 500 secrets in existing KeyVault (test-azure-speedup)
+#   - 2 new KeyVaults with 500 secrets each (test-azure-speedup-2, test-azure-speedup-3)
+#   - Total: 3 vaults, 1500 secrets
+#
+# Usage:
+#   1. cd scripts/
+#   2. terraform init
+#   3. terraform plan
+#   4. terraform apply
+#   5. To cleanup: terraform destroy
