/* ============================================
   KTCS2 Portal Styles (메인과 동일)
   ============================================

   이 파일은 공통 CSS를 임포트하고
   KTCS2 프로젝트 전용 스타일을 정의합니다.

   공통 CSS 구조:
   - variables.css: 색상, 폰트, 간격 등 변수
   - layout.css: 페이지 레이아웃, 그리드 시스템
   - components.css: 버튼, 폼, 카드 등 컴포넌트

   주의: 이 파일의 모든 CSS는 공통 CSS 이후에 작성되어
   필요시 공통 설정을 오버라이드할 수 있습니다.
