GOOGLE LOGIN

Feature Title: Google Login (Sign in with Google)

What do you want:
Allow users to sign in to Sonority using their existing Google account via OAuth 2.0. A "Sign in with Google" button on the login and registration screens would authenticate users instantly, without needing to create a separate email/password credential.

Who does it help:
All users — Musicians, Makers, Touring Pros, and Studios. Especially valuable for new users during onboarding, reducing friction at the sign-up stage and increasing conversion. Returning users benefit from one-tap access without remembering a password.

Current workaround:
Users must manually create and remember a separate Sonority email/password combination, or use a password manager. There is no social login shortcut currently available.

Mockup or example: (optional)
Reference: accounts.google.com/signin — standard "Sign in with Google" button (white pill button with Google logo). Common implementation examples: Spotify, Reverb, Bandcamp onboarding flows.
