+`command notify TEXT` speaks a notification and retains it for **Fenrir+N** and
+**Fenrir+Control+N**. History holds the latest 100 notifications for this reader
+session, including messages received while speech is muted or temporarily
+silenced. `command say TEXT` remains self-voicing and does not add history.
+Received times use the current time format in Presentation's Time and date
