Fix Font Display Strategy
Medium Impact+8 points estimated
Why It Matters
FontAwesome fonts cause 320ms render blocking and delay FCP by 300ms.
How to Fix
Add 'font-display: swap' to @font-face declarations for fa-solid-900.woff2. Preload critical font files with <link rel='preload' as='font'>. Consider using system fonts or subset FontAwesome to include only used icons.

AI Performance Analysis
This website has good performance with a score of 82/100, but has room for improvement in loading speed. The biggest issue is excessive unused CSS code, particularly from Bootstrap and FontAwesome files that are 92-99% unused, which is slowing down your Largest Contentful Paint by 450ms and wasting 42 KiB of data. Additionally, render-blocking scripts and stylesheets are delaying your initial page render by nearly a second, while oversized images are unnecessarily large for their display dimensions. Removing unused CSS, deferring non-critical resources, and properly sizing images could easily push your performance score above 90 and significantly improve user experience.

High Impact+12 points estimatedWhy It Matters:
43 KiB of unused CSS is delaying LCP by 450ms and blocking initial render.
How to Fix:
Use PurgeCSS or UnCSS to remove unused FontAwesome (99% unused) and Bootstrap (92% unused) rules. Consider loading only required FontAwesome icons via tree-shaking. Inline critical CSS for above-the-fold content and defer non-critical stylesheets.
Optimize Image Delivery
High Impact+10 points estimatedWhy It Matters:
Oversized images waste 78 KiB and delay LCP by 300ms with poor responsive behavior.
How to Fix:
Generate responsive image sizes for banner.webp (1352x459 displayed as 388x132) and left-main.webp (858x574 displayed as 388x260). Add explicit width/height attributes to logo.svg to prevent layout shifts. Implement srcset with multiple image sizes for different viewport widths.
