Okay nice ! but few things:

• you have to add you as authors on blog https://github.com/nodejs/nodejs.org/blob/main/apps/site/authors.json
• a mention of when styleText became stable and if you are on app verify that you are on the right version (on prod). And if you are using it on package the user have to check their nodejs version support and reming them that changing node.js version support is a major bump on their package
• last but no least a paragraph to thanks the maintainer. because without npm ecosystem node can't exist.
