   색상 고정 (다크모드 대응)

   이 사이트는 라이트 색상 하나로만 갑니다. 그런데 삼성 인터넷·크롬의
   "자동 어둡게" 기능은 다크 대응이 없는 페이지를 임의로 반전시켜서,
   노란 로고가 갈색으로 보이는 등 색이 망가집니다.

   아래 블록은 "이 사이트는 다크모드를 직접 처리한다"고 브라우저에 알려
   자동 반전을 끄기 위한 것입니다. 위 :root 의 색 변수는 그대로 두므로
   다크모드에서도 라이트와 완전히 같은 색이 나옵니다.
   → 색을 바꾸려면 위 :root 한 곳만 고치면 됩니다. 여기는 건드릴 필요 없습니다.
