A tablet-sized forgot-password authentication screen from the Keystone auth UI kit. A dark purple thermal-gradient hero reads 'Regain access in minutes.' with a secure-recovery subtitle. Below, a white form card contains an empty email field highlighted in a red error state with the message 'Please enter your email', plus a filled indigo 'Send Reset Link' primary button, a 'Back to Log in' secondary button, and a company footer.
