* Responsive Audit Tests
*
* These tests verify the responsive_audit tool functionality using the
* Chrome Playwright testing harness. The responsive audit detects:
* - Layout issues (collapsed content, fixed element coverage, margin/padding squeeze)
* - Overflow issues (horizontal scroll, clipped content, truncated text, squeezed images)
* - Accessibility issues (touch target size, iOS zoom triggers, readability)
*
* Prerequisites (handled by globalSetup):
* - Fixture server running on port 8765
* - agnt daemon running
* - agnt proxy running on port 12345, targeting fixture server
