Fix Image Layout Shifts
High Impact+15 points estimated
Why It Matters
Unsized images cause 0.22 CLS score and create jarring content jumps during loading.
How to Fix
Add explicit width and height attributes to all images, especially the head-splash.webp causing the largest shift. Use CSS aspect-ratio property to maintain responsive behavior while reserving space. Preload the LCP image to prevent layout shifts.

AI Performance Analysis
This website has poor performance with a score of 56/100, indicating significant user experience issues. The biggest problem is excessive main-thread work taking 33.7 seconds, which is causing the page to become interactive only after 17.3 seconds - far too slow for users. The site is also suffering from render-blocking CSS files that could save 2.2 seconds in load time, layout shifts caused by unsized images, and image optimization issues that could save 116KB in downloads. Prioritizing the reduction of JavaScript processing time, deferring non-critical CSS, and properly sizing images would dramatically improve the site's performance and user experience.
Other Optimization Recommendations
Eliminate Render Blocking Resources
High Impact+25 points estimatedWhy It Matters:
CSS files are blocking initial page render and delaying LCP by 2.2 seconds.
How to Fix:
Inline critical CSS for above-the-fold content directly in the HTML head. Defer loading of card-animations.css and theme CSS using media='print' onload='this.media="all"'. Consider replacing the large Tailwind CDN (127KB) with a custom build containing only used classes.
Reduce Main Thread Work
Medium Impact+10 points estimatedWhy It Matters:
33.7 seconds of main thread blocking creates 430ms input delay and prevents user interactions.
How to Fix:
Profile JavaScript execution to identify bottlenecks in the 17.4s of 'Other' work. Break up long-running tasks using setTimeout or requestIdleCallback. Optimize forced reflows in theme-system.js by batching DOM reads and writes separately.
