Lots of things learned, lots of fun edge cases discovered (hello moving web components to iFrames in Firefox)

I am building. Will have lots to share and talk about soon 😊

I was curious how it works. We have a massive list of font families, weights and styles that affect the text box. How does CSS ensure the text box is calculated correctly?

I did some experiments with canvas which seemed to be able to get very close.
