This is not visible in production, but only debug. It shows three variables
being used to change the settings screen (title, icon and title-punctuation).
Just moving the `html` tag to the beginning (to be the parent of the `head`, rather than its next-sibling).
I'm also deindenting `body` and its contents so that the indentation is consistent. (Alternately, we could increase the indentation of `head` and all of its contents, but that seems unnecessary, and it would probably force the `img#wordmark` /**/ comment to wrap to 3 lines. Seems simpler to just have html/body/head all at the same level of indentation, which is a somewhat common practice to save on indentation.)
This fixes#901.
