[!NOTE]
This is a best-practice recommendation, not a definite WCAG failure.

What

An accessibility scan flagged an element on https://torchbox.github.io/django-pattern-library/demo/render-pattern/patterns/pages/forms/example_form.html because document should not have more than one main landmark. Learn more about why this was flagged by visiting https://dequeuniversity.com/rules/axe/4.11/landmark-no-duplicate-main?application=playwright.

The following element needs attention:

• <main> (selector: body > main)

To fix this, ensure the document has at most one main landmark.

Specifically:

Fix any of the following:

• Document has more than one main landmark

Acceptance Criteria

• The specific violation reported in this issue is no longer reproducible.
• The fix MUST meet the accessibility standards specified by the repository or organization (WCAG 2.2 if applicable).
• A test SHOULD be added to ensure this specific violation does not regress.
• This PR MUST NOT introduce any new accessibility issues or regressions.

Start from the demo page at /django-pattern-library/demo/render-pattern/patterns/pages/forms/example_form.html and locate the template producing body > main. Run the referenced axe landmark-no-duplicate-main check against that page, then adjust the markup so the violation is gone. Add a regression test if the repository’s accessibility test setup supports it, and verify no new accessibility issues appear.
