Bumps button contrast to match the treatment on reactnative.dev. Dark mode: - primary text: dark:text-secondary (#404756) -> dark:text-gray-90 (#23272F) - secondary border: #404756 -> #4E5769 (matches RN's rgb(78,86,104)) Light mode: - secondary border: #D9DBE3 -> #BCC1CD (matches RN's rgb(188,193,205)) gray-90 keeps a subtle cyan tint on the teal button, per review feedback (gray-95 was too flat).

Details
The global bundle is the javascript bundle that loads alongside every page. It is in its own category because its impact is much higher - an increase to its size means that every page on your website loads slower, and a decrease means every page loads faster.
Any third party scripts you have added directly to your app using the <script> tag are not accounted for in this analysis

Details
Only the gzipped size is provided here based on an expert tip.
First Load is the size of the global bundle plus the bundle for the individual page. If a user were to show up to your website and land on a given page, the first load size represents the amount of javascript that user would need to download. If next/link is used, subsequent page loads would only need to download that page's bundle (the number in the "Size" column), since the global bundle has already been downloaded.
Any third party scripts you have added directly to your app using the <script> tag are not accounted for in this analysis
Next to the size is how much the size has increased or decreased compared with the base branch of this PR. If this percentage has increased by 10% or more, there will be a red status indicator applied, indicating that special attention should be given to this.
