Global styles: base font and scale

[karmatosed]

Being able to easily adjust a scale of typography opens up some powerful combinations of design. There could be 2 potential ways of doing this.

Declare a base font

Pull base from text

The other option is to have the text size be the base and just scale up from it, simply showing a scale and in conjunction with #21028 show that size.

Wider picture

In the context of global styles this could look like the following picture:

Feedback

As it would be great to move this to development, deciding which approach would be a great step here to continue forward.

Really nice mockups.

As I looked at the GIF of the delicious work in progress in #20530 (comment), however, I realized that headings in my themes often diverge wildly from a typescale, whether it be through font sizes, or even font weights and styles, perhaps even fonts. Locking it to body and header feels like it might be a simpler user interface up front compared to showing options for headings 1 through 6 — but the latter ultimately seems like the way that will frustrate less.

There has been a lot of work in this area which means this issue is no longer valid. I am therefore going to close it to allow focus.
