Font is showing in production but not in local

[juskek]

Describe the bug

Fonts are showing in production but not in local.
I pushed my last article over 2 weeks ago, and the fonts were working fine in local and production.
I came back today and the fonts are not loading anymore in local :')

I've narrowed it down to a missing css variable, see screenshots

Screenshots
In local,

In production,

What I've tried

1. Restart server
2. Empty cache and hard reload

Strangely... I did the following:

1. vercel dev -> saw fonts being applied in local
2. Stopped local server
3. yarn dev
4. Empty cache and hard reload
5. fonts are now being applied in local... ??

Might be a Next / Vercel font optimisation issue.
