/* ---------------------------------------------------------------------------
   Lightmorphic Paste, site styles

   The look is editorial rather than product-page: a dark ground, a serif for
   anything you actually read, and a monospace only for labels and numbers.
   Dark is the only theme here. The extension itself still follows the browser
   and still has a switch; the website does not.
   The single accent is a marker-pen stroke, drawn behind words rather than
   under them, so nothing on the page is underlined.
