Prompt given to the model

Build a set of checkboxes in a single self-contained HTML file (inline CSS and JS, no build step, no external libraries). Present a "Pizza toppings" question where the user can choose any number of these options: Mushrooms, Pepperoni, and Extra cheese. At least one topping must be chosen. None is selected yet, so the question is in error: show the validation message "Choose at least one topping." for the pizza toppings question. Output the complete code in one HTML code block.
