+      <strong>How scheduling works:</strong>
+      These jobs are executed by the Celery Beat scheduler running inside the worker container.
+      Schedule changes (cron / interval) and enable / disable toggles are persisted immediately,
+      but the Celery Beat process reads the schedule only at startup — so changes take effect
+      after the worker is restarted.  You can always trigger any job <strong>right now</strong>
+      using the <em>Run Now</em> button without restarting.
