Performance improvements observed:
* **Latency:** Reduced by ~18.1% (from 1.01s to 827.47ms)
* **Requests per Second:** Increased by ~24.1% (from 381.16 to 472.85)
* **Transfer per Second:** Increased by ~24.1% (from 0.87MB to 1.08MB)
These gains demonstrate the effectiveness of caching inlined CSS for frequently accessed pages, resulting in a faster and more efficient user experience.
