// User represents one account in our system. It can be authenticated in
// two different ways, both represented on the same row:
//   - Password login: PasswordHash is set, GoogleID is empty.
//   - Google login:   GoogleID is set, PasswordHash is empty.
//   - Both:           a password user later links a Google account (or
//                      vice versa), and both fields end up populated.
//
// Deliberately NOT included here: a plaintext Password field. This struct
// should never hold a plaintext password in memory beyond the brief moment
// it's hashed during registration - see handlers.Register.
