Prompt given to the model

Build a single checkbox in a single self-contained HTML file (inline CSS and JS, no build step, no external libraries). It is a consent checkbox labelled "I agree to the terms and conditions". Ticking it is mandatory. The checkbox is currently unticked, so the field is in error: show the validation message "You must agree to the terms and conditions to continue." for the checkbox. Output the complete code in one HTML code block.
