Understanding the start render

RE: Understanding the start render
How can I tell that the document is visible right after the first line? The page (as-displayed) includes the image and other elements that haven't been loaded yet so that isn't what is actually presented on the screen.

Sorry, I just noticed that the scripts are async so they aren't what is blocking the UI (directly) but the loading of the css is and in the test you ran the css is competing with the javascript and a few of the images for the available bandwidth.

If you go to the video tab in the advanced settings you can enable video capture of the browser loading and watch to see what happens. I can guarantee that nothing will be displayed until after the css has been loaded (it blocks the render tree but not the dom tree which is why domcontentready fired so quickly).
