Visual Testing & Accessibility — quiz

Your test calls `await expect(page).toHaveScreenshot('home.png')`. The first run passes (and saves a baseline). The third run fails with a tiny pixel diff. What's the most likely cause?

• Playwright is buggy
• Tiny diffs typically come from font anti-aliasing, animations, blinking carets, or async-loaded images — handle with `mask`, `animations: 'disabled'`, or accept a small `maxDiffPixelRatio`
• `toHaveScreenshot` only works in headless mode
• Screenshots can never be deterministic — don't use them
