Utilize Font Weights in Hybrid mode

Currently, when choosing a custom font you can only pick a single weight. When enabling hybrid mode, it uses a different, fixed font which may break visual consistency with the rest of the OS.

Instead, why not give users the ability to upload custom fonts with multiple weights and automatically pick a lower weight of the chosen font for hybrid mode?

Alternatively, you could let users pick/customize their “hybrid font”. I'm unsure which option would be more streamlined and easier to implement in your code base, but would be happy with either.
