   The hero slider runs full-bleed underneath the header, which turns

   1. A gradient scrim behind the header (see slider.css) guarantees
      contrast no matter what photo the client uploads — light text on
      an unknown image is otherwise a coin toss.
   2. Once scrolled away from the hero the header returns to its solid
