Font Subsetting
Optimise your fonts by only providing what's needed.
Just read this: https://www.sarasoueidan.com/blog/glyphhanger/
TLDR:
Run glyphhanger {your(dev)domain} --spider-limit=0 --subset="*.ttf".
- Replace
*ttfwith your font’s actual name, if or suffix. - Needs to be called in font directory.
