/* 배경 이미지 크기 권장사항:
   
   현재 설정 (background-size: cover)을 사용하면:
   - 이미지가 컨테이너를 완전히 채우도록 확대/축소됩니다
   - 화면 비율에 따라 이미지의 일부가 잘릴 수 있습니다
   - 중요한 내용은 중앙에 배치하는 것이 좋습니다
   
   권장 이미지 크기:
   - 최소 크기: 1920px × 1080px (16:9 비율, Full HD)
   - 권장 크기: 2560px × 1440px (16:9 비율, 2K)
   - 최적 크기: 3840px × 2160px (16:9 비율, 4K) - 고해상도 디스플레이용
   
   파일 크기 최적화:
   - JPG 형식 권장 (배경 이미지용)
   - 파일 크기: 200KB ~ 500KB (로딩 속도 고려)
   - WebP 형식 사용 시 더 작은 파일 크기 가능
   
   이미지 비율:
   - 16:9 비율 권장 (가로형)
   - 21:9 비율도 가능 (울트라와이드)
   - 세로형 이미지는 잘릴 수 있으므로 주의
*/

/* 배경 이미지 변경 방법:
   1. HTML의 hero-background-image div의 style 속성에서 url 변경
   2. 또는 CSS에서 아래 주석을 해제하고 원하는 이미지 경로로 변경

   .hero-background-image {
       background-image: url('images/company_01.png');

   - rgba(255, 255, 255, 0.75)에서 마지막 숫자(0.75)를 조절하세요
   - 숫자가 낮을수록 배경 이미지가 더 선명하게 보입니다
   - 예: 0.9 = 거의 불투명, 0.7 = 약간 투명, 0.5 = 반투명, 0.3 = 매우 투명
   - 권장값: 0.7 ~ 0.85 (텍스트 가독성과 배경 이미지의 균형)
   
   backdrop-filter의 blur 값도 조절 가능:
   - blur(1px) = 약한 블러 (배경이 더 선명)
   - blur(3px) = 강한 블러 (배경이 더 흐릿)
