+# scripts/dev.sh – lokaler Dev-Launcher für ReBreak-Apps
+#
+# Wichtig: Backend wird NICHT gestartet. Die Apps laufen gegen den
+# konfigurierten Server (z. B. staging.rebreak.org). Backend nur lokal
+# entwickeln/testen, wenn explizit `backend` übergeben wird.
+#
+# Usage:
+#   ./scripts/dev.sh magic    # apps/rebreak-magic Tauri-Dev (gegen Server)
+#   ./scripts/dev.sh admin    # apps/admin Nuxt-Dev
+#   ./scripts/dev.sh native   # apps/rebreak-native Expo-Start
+#   ./scripts/dev.sh backend  # backend Nitro-Dev (lokales Backend)
