Firebase

Covers the full Firebase stack with a realistic edge: security rules are harder than they look, and pricing surprises happen when you design listeners poorly. The patterns show modular SDK imports for tree-shaking, security rule helpers that actually make sense, and data modeling that embraces denormalization instead of fighting it. Includes real-time listener cleanup, which matters because forgotten subscriptions burn reads. The scope smartly punts payments to Stripe and auth flows to OAuth skills. Useful if you're past the tutorial phase and need to see how Firebase patterns actually work in production, especially around Firestore query limitations and the read-heavy tradeoffs.
