/* ===== AOS 애니메이션 강제 표시 및 충돌 해결 ===== */

  AOS는 기본적으로 data-aos 속성이 있는 요소를 opacity: 0으로 숨깁니다.
  투명 배경과 충돌하여 요소가 계속 숨겨지는 문제를 해결하기 위해,
  애니메이션 시작 전에도 요소가 보이도록 초기 상태를 재정의합니다.

/*
  AOS가 스크롤을 감지하고 'aos-animate' 클래스를 추가하면,
  그때서야 우리가 원하는 최종 상태(애니메이션 완료 상태)로 변경되도록 합니다.
  실제로는 아래 스타일이 적용될 때 아무 변화가 없는 것처럼 보이지만,
  AOS 라이브러리가 정상적으로 작동하고 있다는 증거가 됩니다.
