This example shows a form-based user creation interface where the browser’s HTML parser rearranges the submitted markup. The code uses a Processing.js script inside a `script` tag to define a canvas variable, but the actual rendered page moves the submit button outside the form and inserts a literal `0` inside the form element. The discrepancy arises from how the browser handles unclosed form tags and embedded scripts, resulting in a different DOM structure than the expected source. The form action points to `/users`, but the visible output contains no functional form controls.
