/* The billing site, in the look of dfwtechpros.com: black and white, square corners, heavy uppercase type, white buttons on black. The
   menu is black in both themes (like the website's header); the page behind it is black in the dark theme and white in the light one.
   Colour is used only to say that something is wrong (red) or needs a look (amber). No inline styles anywhere: the
   Content-Security-Policy forbids them. */
