+"""Browser test for the AppAPI admin settings page.
+
+Regression for https://github.com/nextcloud/app_api/pull/1034: on stable32 a
+dependency bump paired the bundled @nextcloud/vue 8.17.1 with @nextcloud/l10n
+3.4.1, so the admin settings script threw "Cannot read properties of undefined
+(reading 'catalogs')" while loading. The page stayed empty without any server
+error, so the test checks both the rendered content and the absence of errors.
