+# Busch-Radio Spotify Bridge – Startup-Script
+#
+# Startet:
+#   1. Icecast2   – HTTP-Stream-Server
+#   2. librespot  – Virtueller Spotify Connect-Empfänger (gibt PCM auf stdout aus)
+#   3. ffmpeg     – Kodiert PCM → MP3 und schickt es als Icecast-Quelle
+#
+# Bei Absturz wird die komplette Pipeline nach 5 Sekunden neu gestartet.
