Does Firebase persist the user across reloads?
Yes, Firebase persists the user by default. Listen to auth state changes in your context so the user is set on app load, and the user stays logged in across page reloads without re-authenticating.

Create a Firebase project, install the SDK, initialize it, create an AuthContext that tracks the user and exposes sign up, sign in, and sign out, build login and signup pages, protect routes, and listen to auth state changes so the user persists across reloads.
Create an AuthContext provider that listens to Firebase auth state changes and exposes the current user plus signup, signin, and signout functions. Wrap your app in the provider so any component can access auth state.
Create a ProtectedRoute component that checks the auth state and redirects unauthenticated users to the login page. Wrap your authenticated pages like browse in it so only logged-in users can access them.
