I duplicated pages a few times to maintain styling, but on the latest duplication the fonts refuse to load as they did on the previous pages. The code didn't change initially (I have sense messed with stuff trying to get it to render).
The two generators on the linked list will show you the correct font being rendered ('Share Tech Mono').
Edit: Currently using the Monospace system fallback, but really bizarre functionality. Appears to be generator specific, and many other google fonts also not rendering on this specific page.
That worked, thank you!
Trailing ' also fixed.
