/* ============================================
   LGEUP Portal Styles v2.0
   ============================================

   CSS 구조:
   1. 전역 설정 (Reset, 변수)
   2. Typography (텍스트)
   3. Components (버튼, 폼)
   4. Layouts (로딩, 페이지)
   5. Pages (로그인, 메인)
   6. Utilities (반응형)

   네이밍: BEM (Block__Element--Modifier)
   예: .login-form__input--focus

   ============ 2025-11-03 최근 변경사항 ============

   1. 웹폰트: Pretendard (weights 100-900)
      - font-display: swap으로 성능 최적화

   2. 버튼 스타일 (로그인 페이지)
      - 로그인: #FF9999 (주요 버튼, 2fr 비중)
      - 회원가입: #FFB3B8 (보조 버튼, 1fr 비중)
      - 비밀번호 변경: #FFCCCC (2fr 비중)
      - 비밀번호 찾기: #FFE5E5 (1fr 비중)
      - 모든 버튼: text color #333 (어두운색)
      - 모든 버튼: justify-content: center, text-align: center (가운데 정렬)

   3. 폼 입력 필드
      - .form-group__input: text-align: center (입력값 가운데 정렬)

   4. 레이아웃
      - .login-button-row: grid 2fr 1fr (로그인/회원가입)
      - .password-buttons: grid 2fr 1fr (비밀번호 변경/찾기)

   5. 로그인 페이지
      - 배경: #ffffff (흰색)
      - 로그인박스: #F0ECE4 (베이지)
      - 헤더: #262626 (다크그레이) + 흰색 텍스트
      - h2/subtitle 제거됨
