   1. Put your image in the folder  images/hero/   (for example wallpaper.jpg)
   2. Change  --hero-image: none;  to  --hero-image: url('../images/hero/wallpaper.jpg');
   3. Set  --hero-overlay  between 0 (no dark layer) and 1 (fully dark).
      0.55 to 0.75 keeps the text readable on most photos.
   The same idea works for the dark banner at the top of every inner page (--page-image). */
