   Bootstrap classes already use consistently, plus the hero banner
   separately. background-blend-mode removes the source JPG's white
   background so only the mark itself shows, small and unobtrusive.
   Disappears naturally once the real photo renders on top.
   The flash animates background-color (not opacity) specifically so
   it can never affect the actual photo once it's loaded — opacity
   would apply to the whole element, background-color only to the
   background layer sitting behind the (eventually opaque) image. */
