Account
Sign in with email and password, or Google. One account is one player. A public username is unique (case-insensitive) and shown on leaderboards. If you skip choosing one, DIGIGMA assigns a neutral name. Email stays private. Country is optional and can show a flag. Forgot password sends a reset link if an account exists for that email.
