Fix Forced Reflow Issues
Medium Impact+1 point estimated
Why It Matters
JavaScript is causing 92ms of forced reflows that block the main thread and hurt INP.
How to Fix
Batch DOM reads and writes to avoid layout thrashing in app-B75yEAbr.js. Use requestAnimationFrame for DOM measurements. Cache geometric property values instead of repeatedly querying offsetWidth/offsetHeight.

What This Score Means
A score of 97 falls in the "Good" range (50-89). While it is better than poor (0-49), you should aim for 90+ to provide an optimal user experience and maximize SEO benefits.
This site is slower than approximately 35% of similar sites. The main issues affecting performance are image optimization, JavaScript execution time, and layout stability.
Addressing these issues could improve your conversion rate by 15-20% and boost your search engine rankings.

AI Performance Analysis
This website achieves an excellent performance score of 97/100, indicating very fast loading times for users. However, the biggest opportunity for improvement is reducing unused JavaScript code, which could save an estimated 69KB and improve loading times by up to 300ms - this includes removing unnecessary code from both the main app bundle and analytics tracking scripts. The site also has a render-blocking CSS file that delays initial page rendering by about 150ms, and some JavaScript functions are causing forced reflows that impact smoothness. While these issues are relatively minor given the high overall score, addressing the unused JavaScript would provide the most meaningful performance boost for users.
Other Optimization Recommendations
Remove Unused JavaScript Code
High Impact+2 points estimatedWhy It Matters:
70KB of unused JavaScript is delaying LCP by 300ms and wasting bandwidth.
How to Fix:
Analyze Matomo tracking script and remove unused features (56% unused). Use tree-shaking in your build process to eliminate dead code from app-B75yEAbr.js (62% unused). Consider loading analytics scripts asynchronously after page load.
Eliminate Render-Blocking CSS
High Impact+1 point estimatedWhy It Matters:
CSS file is blocking initial render and delaying LCP/FCP by 150ms.
How to Fix:
Inline critical CSS directly in the HTML head for above-the-fold content. Load non-critical CSS asynchronously using media='print' onload="this.media='all'" technique. Consider splitting CSS into critical and non-critical bundles in your build process.
