Account not found
Social/OAuth login completed with the provider, but the app could not load the matching user row (“Account not found.”).
Why this happens
Race, deletion, or data integrity: OAuth mapping pointed at a missing User. Distinct from “email already registered,” inactive/pending verify, or provider misconfiguration.
Diagnose and fix
1. Member: try register/login again, or use password login if they have one.
2. Admin: check Users for that email; restore if soft-deleted; re-link social login if needed.
3. Confirm Social login / Google/Apple/Facebook settings and OAuth redirect URI.
4. If the account is inactive/pending, expect those messages instead once the row exists.
