By default, a standard set of fonts for the template is registered. I want to change only the size and font style, but this is impossible without choosing a font. And there is a whole set of fonts, not just one. It's a dead end...

In a good way, there should be a default item and everything is solved. Otherwise, some fonts are loaded on the page, and others are loaded for a specific title. Here the speed immediately drops...

This is for cases when a standard set of fonts really suits you
