   inline style attributes as well as inline <style> blocks. These carry the widths
   the hour and day bars would otherwise have set inline, so the page needs no
   'unsafe-inline' to draw correctly. An hour's width is (pimpness - 60) / 100, as
   in NowScreen.kt, so a worse hour draws a longer bar. */
