Your question is Cross-Browser and Accessibility. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How do you ensure cross-browser compatibility and accessibility in a complex web application?
Explain how you would design a practical, automated validation system covering browser and device coverage, semantic HTML, keyboard navigation, screen readers, visual regressions, and release gates. Discuss where batch analysis, browser-based inference, and human review fit, while accounting for flaky tests, false positives, feature drift, training-serving skew, and developer feedback loops.
