Key issues

1. Network dependency tree
   0/100
   [Avoid chaining critical requests](https://developer.chrome.com/docs/performance/insights/network-dependency-tree) by reducing the length of chains, reducing the download size of resources, or deferring the download of unnecessary resources to improve page load.
2. Reduce unused CSS
   0/100
   Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity. [Learn how to reduce unused CSS](https://developer.chrome.com/docs/lighthouse/performance/unused-css-rules/).
3. Forced reflow
   0/100
   A forced reflow occurs when JavaScript queries geometric properties (such as offsetWidth) after styles have been invalidated by a change to the DOM state. This can result in poor performance. Learn more about [forced reflows](https://developer.chrome.com/docs/performance/insights/forced-reflow) and possible mitigations.
4. Legacy JavaScript
   0/100
   Polyfills and transforms enable older browsers to use new JavaScript features. However, many aren't necessary for modern browsers. Consider modifying your JavaScript build process to not transpile [Baseline](https://web.dev/articles/baseline-and-polyfills) features, unless you know you must support older browsers. [Learn why most sites can deploy ES6+ code without transpiling](https://developer.chrome.com/docs/performance/insights/legacy-javascript)
5. Reduce unused JavaScript
   0/100
   Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity. [Learn how to reduce unused JavaScript](https://developer.chrome.com/docs/lighthouse/performance/unused-javascript/).
