+ * Regression test for: "Fix MCP server Runtime page crash when an endpoint is removed"
+ *
+ * This covers the mirror case of 00-runtime-config-endpoint-display.cy.js.
+ * That spec deletes the SANDBOX endpoint and verifies the Runtime page doesn't
+ * crash when production_endpoints.url exists but sandbox_endpoints.url is null.
+ *
+ * This spec deletes the PRODUCTION endpoint instead, verifying the Runtime page
+ * doesn't crash when sandbox_endpoints.url exists but production_endpoints.url
+ * is null — the other half of the optional-chaining fix mentioned in the bug.
