First Contentful Paint 0.3 s

First Contentful Paint marks the time at which the first text or image is painted

Reduce JavaScript execution time 2.7 s

These are the largest layout shifts observed on the page. Each table item represents a single layout shift, and shows the element that shifted the most. Below each item are possible root causes that led to the layout shift. Some of these layout shifts may not be included in the CLS metric value due to [windowing](https://web.dev/articles/cls#what_is_cls)
