A generated form renders correctly for a sighted developer. The application must support keyboard and screen-reader users. What is the most appropriate acceptance step?

1. Ask Copilot to add a comment stating that the form is accessible.
2. Validate focus order, labels, error announcements, and keyboard operation against the accessibility requirements.
3. Measure the contrast of the submit button and treat that as full accessibility validation.
4. Accept the form if the UI framework advertises accessible components.
