Accessibility issue: Heading levels should only increase by one on /django-pattern-library/demo/render-pattern/patterns_jinja/pages/search/search.html

[!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_jinja/pages/search/search.html because heading levels should only increase by one. Learn more about why this was flagged by visiting https://dequeuniversity.com/rules/axe/4.11/heading-order?application=playwright.

The following element needs attention:

• <h4>16</h4> (selector: h4:nth-child(2))

To fix this, ensure the order of headings is semantically correct.

Specifically:

Fix any of the following:

• Heading order invalid

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 with the rendered search page at patterns_jinja/pages/search/search.html and inspect the heading structure around the reported h4:nth-child(2) element. Run the repository's accessibility scan or Playwright check to reproduce the heading-order violation. Done means the h4 sequence is semantically ordered, the reported violation is gone, and a regression test is added if the existing test setup supports it.
