 requests can also be enabled separately in the `[remote]` section.

+`command notify TEXT` plays `notification.wav` when sounds are enabled, at most
+once every 30 seconds across readers for the same user. It waits for a played
+cue to finish before speaking. Notifications during the cooldown are spoken
+without another sound; skipped cues are not queued for later. Only the targeted reader speaks or plays
+the cue. All running readers for that user share the latest 100 notifications
+for **Fenrir+N** and **Fenrir+Control+N**, including messages received while
+speech is muted or temporarily silenced. Other readers receive silent history
+updates. The root console reader shares the active text-console user's history;
+switching console users switches histories. A newly started reader loads the
+current history silently. History stays in memory until the last reader for
+that user exits. `command say TEXT` remains self-voicing and does not add history.
