How to use roam/render to publish to the web

The workflow consists of three major components:

1. A Cloudflare Worker to host the pages
2. A custom roam component to trigger the publishing and the unpublishing
3. Some JavaScript to handle the publishing and unpublishing
4. Optional: set up a smartblock

Please note: you are doing everything at your own risk! If you don't have a basic understanding of how roam/js works and know basic javascript, please don't use this!

Text is invisible while webfonts are loading

Which font-display value to use?

This depends a lot on how you are using your webfont, and whether rendering the text in a fallback font makes sense. For example, if you're rendering the main body text on a site, you should use font-display: optional. On browsers that implement it,
