Reduce Main Thread Blocking Time
High Impact+15 points estimated
Why It Matters
Excessive main thread work (32.6 seconds) creates a 4-second blocking time, making the page unresponsive to user interactions.
How to Fix
Replace the heavy Tailwind CDN (127KB) with a custom build containing only used classes. Optimize JavaScript execution by breaking up long tasks using setTimeout or requestIdleCallback. Address the 108ms of forced reflows in theme-system.js by batching DOM reads and writes separately.

What This Score Means
A score of 31 falls in the "Poor" 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 has severe performance issues with a critically low score of 31/100, indicating a very poor user experience. The biggest problem is render-blocking CSS files that are preventing the page from displaying content quickly, causing an estimated 2.2 second delay in both First Contentful Paint and Largest Contentful Paint. Additionally, oversized images are wasting over 1.2MB of bandwidth and further slowing down the page, while the site takes an unacceptable 17.5 seconds to become fully interactive. To dramatically improve performance, the site should defer or inline critical CSS, optimize and properly size images, and reduce the massive amount of main-thread work that's blocking user interactions.
Other Optimization Recommendations
Eliminate Render-Blocking CSS Resources
High Impact+25 points estimatedWhy It Matters:
CSS files are blocking initial page render, delaying LCP by 2.2 seconds and causing the massive performance bottleneck.
How to Fix:
Inline critical CSS for above-the-fold content directly in the HTML head. Load non-critical CSS files (suit-backgrounds.css, cards-3d.css, components.css) asynchronously using media='print' onload='this.media="all"' technique. Consider combining CSS files to reduce HTTP requests.
Optimize and Resize Images
High Impact+20 points estimatedWhy It Matters:
Oversized images waste 1.2MB of bandwidth and delay LCP by 6.2 seconds, significantly impacting load performance.
How to Fix:
Resize images to match their display dimensions (e.g., 1024x1024 images displayed at 443x443). Implement responsive images using srcset attribute for different screen sizes. Increase compression levels or convert to more efficient formats like AVIF. Add explicit width and height attributes to prevent layout shifts.

Reduce Unused JavaScript Payload
330 KiB of unused JavaScript delays LCP by 400ms and blocks the main thread for 2 seconds.
Optimize Font Loading Strategy
Font loading delays are causing 650ms delay to First Contentful Paint and creating invisible text periods.
Add Image Dimensions Attributes
Missing width and height attributes on images cause layout shifts that hurt user experience and CLS scores.
