Hello @aguscha333!
You can customize the font used by Storybook. See this PR from the v1 website for an example. The short-end of it: you can add to the <head> via the storybook.config.js file. Here is a related page from Storybook’s documentation
This doesn’t make use of the dedicated preview-head.html, but should still make the font-family available to your styling.
