Implement Modern Image Formats
Medium Impact+3 points estimated
Why It Matters
The header logo can be compressed by 4.8 KiB using modern formats for better loading performance.
How to Fix
Configure imgproxy service to serve WebP/AVIF formats with higher compression. Add srcset with multiple format options and let browser choose optimal format. Ensure lazy loading is properly implemented for non-critical images.

AI Performance Analysis
This website has good performance with a score of 84/100, but there's significant room for improvement in user interactivity. The biggest issue is excessive unused CSS - over 90% of the 60KB stylesheet is unnecessary, which is slowing down page loading and contributing to a 4-second delay before the page becomes fully interactive. Additionally, JavaScript execution is taking 1.4 seconds and causing forced reflows that block user interactions for 440ms. Removing unused CSS rules and optimizing JavaScript could easily push this site into the 90+ performance range and make it feel much more responsive to users.
Other Optimization Recommendations
Eliminate Unused CSS Rules
High Impact+8 points estimatedWhy It Matters:
53 KiB of unused CSS is delaying both FCP and LCP by 300ms each.
How to Fix:
Audit the main stylesheet at /css/styles.css to remove 90% unused rules. Split critical above-the-fold CSS into a separate inline block. Use PurgeCSS or similar tools to automatically remove unused styles during build process.
Optimize JavaScript Execution Performance
High Impact+12 points estimatedWhy It Matters:
1.4 seconds of JavaScript execution time is causing 440ms of Total Blocking Time, severely impacting interactivity.
How to Fix:
Code-split the Alpine.js bundle to load only required components initially. Move non-critical JavaScript to load after main thread is idle using requestIdleCallback. Optimize forced reflows by batching DOM queries and avoiding geometric property reads after style changes.
