描述

When scoring 100 points on Performance, Accessibility, Best Practices and SEO, fireworks start appearing. However after 10 seconds or so they start stuttering and glitching out before the full animation is played?

研究方向
Investigate the fireworks animation implementation in the Lighthouse report UI. Likely located in the `report/` directory, specifically the JavaScript files that handle the confetti or fireworks effect. Check for any animation loop or timer that could cause stuttering after 10 seconds. Reproduce the bug by scoring 100 in all categories and observe the behavior. Look for any performance related issues or DOM manipulation that might degrade over time.
