+# Sends a notification via unRAID native system and/or Discord webhook.
+# Both channels are optional and independently controlled via Master.conf.
+# unRAID native: requires NOTIFY_UNRAID=true and the dynamix notify script to be present.
+# Discord: requires DISCORD_WEBHOOK to be set to a valid webhook URL.
+# Severity levels: normal, warning, alert — maps to unRAID notification severity.
+# Usage: notify "message" "subject" "severity"
+#        notify "Rsync failed: Movies" "Rsync Alert" "alert"
+#        notify "Daily sync complete" "Daily Sync" "normal"
