   NOTE: This portfolio's animations (scroll reveals, count-ups, subtle ambient

   own machine has that setting enabled and the motion must still be visible.
   The motion is deliberately gentle (short fades/slides, no large parallax or
   flashing), which keeps it comfortable. The only concession we keep is
