Capacitor Push Notifications

This walks you through the full push notification setup for Capacitor apps on both iOS and Android. You get the FCM and APNs configuration steps, Firebase project setup with the actual gradle and podfile changes you need, and code for handling registration, incoming notifications, and user taps. It covers the practical stuff like creating Android notification channels, subscribing to topics, and sending notifications via Firebase Admin SDK. The iOS APNs key setup instructions are clear, which is helpful since that flow trips people up. If you're adding push to a Capacitor app and don't want to piece together the platform-specific config from multiple sources, this consolidates it well.
