   5b. HEADLINE SHEEN

   A band of light travels through the heavy headline. The band is violet,
   not white: on a white page a white band renders the glyphs invisible as it
   passes, which reads as broken rather than polished.

   background-color sits under the gradient so any part of the text the
   gradient has moved past still shows solid ink instead of turning
   transparent.
