/*
  biro51 lightweight reveal

  Progressive enhancement:
  - content is visible by default and stays visible without JavaScript;
  - only opacity and translateY are animated, so layout does not shift;
  - no blur, scale, permanent will-change or endless animation;
  - temporary classes are removed after every reveal.
