@override
List<CharacterAnimation> getAnimations(double progress, int charCount) {
  if (charCount == 0) return [];

  return List.generate(charCount, (index) {
    final staggered = staggeredProgress(progress, index, charCount);
    final curved = applyCurve(staggered);
    final returnT = sin(curved * pi);
    return CharacterAnimation(
      underlineProgress: returnT,
      color: lineColor,
    );
  });
