Describe the Bug

1. In an Astro project with Tailwind integration
2. Add Starlight integration following steps in https://starlight.astro.build/guides/css-and-tailwind/#tailwind-css

Actual: As soon as starlightPlugin() is included in tailwind.config.mjs, the fonts in the "normal" astro pages (outside of content/docs) gets broken, renders as Times

Expected: Both Starlight-based documentation part of the website and normal astro pages respect fontFamily from Tailwind theme.

Okay i can see it something to do with the tailwind starlight plugin changing the font to times in the page directory. Maybe a recommended fix is to just apply to content directory.

I would say try to apply with a class --sl-font just in the content directory.

try to apply with a class --sl-font just in the content directory

Could you please advise how specifically do I do that? Thank you!
