What's the difference between Firestore and the Realtime Database?
Firestore is a newer, document/collection-based database with richer querying, automatic multi-region scaling, and better offline support; the Realtime Database is a simpler single JSON tree, cheaper for very high-frequency small writes but with weaker querying.

How do Firestore Security Rules work?
Security Rules are a separate, declarative configuration that Firestore evaluates server-side on every read/write request, deciding whether to allow it based on the requesting user's auth state and the data being accessed — they're your only real line of defense since client-side checks can be bypassed.
