The most common way this is done is by parsing the font and generating the SDF fields on the fly (usually using Troika - https://github.com/protectwise/troika/blob/main/packages/tro...). It slows down the time to the first render, but it's only a matter of hundreds of ms not seconds, and as part of rendering 3D on webpage no one really expects it to be that fast to start up.
