Prompt given to the model

Build an account details form in a single self-contained HTML file (inline CSS and JS, no build step, no external libraries). Include two text input fields, each with its label shown above the field and a short hint shown below the label: - Full name: hint "As it appears on your bank card." This field is mandatory and currently contains the value "Alex Taylor". - Email address: hint "We'll only use this to email your order confirmation." This field is mandatory and currently contains the value "alex.taylor", which is not a valid email address, so this field is in error: show the validation message "Enter an email address in the format name@example.com." for the Email address field. Output the complete code in one HTML code block.
