Hey xlii! This is Antonio, author of the post.

You're right that rendering is only part of the story. To stay within the ~8ms frame budget, however, every little bit counts. Maintaining application state, layout, painting, and finally pushing pixels to screen, all need to be as performant as they can be.

For layout specifically we're using an approach inspired by Flutter, which lets us avoid complex algorithms but still have a lot of flexibility in the way elements can be positioned and produce a rich graphical experience.

Thanks for reading and commenting!
