   style.css 위에 덧입히는 오버라이드 전용 파일입니다 (v2/v3 미사용).
   네이버 기업 사이트(navercorp.com)의 스타일 규칙을 참고했습니다.
     - 글꼴: Inter(영문) + 나눔휴먼/Pretendard(한글)
     - 글자색: 푸른빛 먹색 #1a1d24, 보조 회색 계열
     - 얇은 헤더(64px), 보통 굵기 메뉴
     - 첫 화면: 큰 사진 카드 + 오른쪽 바로가기 타일 3개 (index.php .n-hero)
     - 굵기 절제: 제목 600~700, 나머지 400~500, 자간 좁게
   포인트 컬러는 기존 #e62d54 를 그대로 사용합니다.
   <body class="design-4"> 일 때만 로드·적용됩니다.
