+Component: UI
+Issues: 14679
+Description: Add an informational message to the CronWorkflow delete confirmation modal indicating that Workflows created by the CronSchedule will also be deleted.
+Author: [minsun yun](https://github.com/miinsun)
+
+- UI/UX only; **no functional logic** is changed.
+- Verified manually by deleting a CronWorkflow in the Workflows UI and confirming the message renders correctly.
