+
+## 8VRF Test Failure Scenarios Simulated
+
+These visual regression tests intentionally fail to represent realistic scenarios QA teams encounter:
+
+1. **Design System Token Updates**: When design tokens change, exact pixel values shift slightly
+2. **CSS Framework Upgrades**: New framework versions may calculate spacing and positioning differently
+3. **Browser Engine Updates**: Different rendering engines handle layout calculations with minor variations
+4. **Web Font Loading Issues**: Font fallbacks cause typography and layout shifts
+5. **Responsive Design Changes**: Breakpoint adjustments affect precise layout expectations
+6. **CSS Property Support Variations**: Newer CSS features have different browser support levels
+
+The 8VRF tests expose the brittleness of pixel-perfect visual assertions and encourage more flexible visual regression testing approaches that account for acceptable variation ranges rather than exact positioning requirements.
