-# Firebase Cloud Messaging setup script
-# =======================================
-#
-# This script creates placeholder files for FCM integration.
-# You must replace them with real values from your Firebase project.
-#
-# Steps to set up Firebase:
-#
-# 1. Go to https://console.firebase.google.com/ and create a project
-#    (or use an existing one)
-#
-# 2. Add an Android app to your Firebase project with package name:
-#    com.devlab.app
-#
-# 3. Download google-services.json and place it at:
-#    android/app/google-services.json
-#
-# 4. Go to Project Settings > Cloud Messaging and copy the
-#    Server key (legacy) or Cloud Messaging API key
-#
-# 5. Set the server key in .env:
-#    FCM_SERVER_KEY=your_server_key_here
-#
-# 6. OR place your Firebase Admin service account key at:
-#    config/firebase-service-account.json
-#    (for the OAuth-based API - more secure)
-#
-# The app will work without FCM configured; push notifications
-# simply won't be sent until Firebase is set up.
-#
