/* =============================================
   Verdi CRM v4.21.0 — Modal Readability & Tone Unification
   ─────────────────────────────────────────────
   🎯 목적: 모든 모달의 가독성을 대시보드 디자인 시스템과 통일
   🐛 해결: 고객 정보 수정 모달의 어두운 입력 배경 + 보이지 않는 라벨 텍스트
   🎨 원칙: 다크 외곽(대시보드 일치) + 밝은 카드 내부(가독성 확보)
            라벨/입력 명확한 콘트라스트 (WCAG AA 4.5:1 이상)
   📐 적용 범위: 모든 .modal-overlay > .modal (전체 모달 일괄 통일)
   🔁 롤백: index.html 의 이 link 1줄 제거 → v4.20.3 톤으로 복귀

   ━━━ 디자인 토큰 (대시보드 v4.18 정합) ━━━
   외곽(헤더):     linear-gradient(135deg, #0b1220 0%, #17253f 100%)  ← 대시보드 BG와 동일 톤
   본문 배경:     #f8fafc                                              ← 밝은 슬레이트
   섹션 카드:     #ffffff + 인디고 좌측 액센트                          ← 카드 가독성 최우선
   라벨:         #1e293b, 600, 13px                                    ← 명확한 슬레이트-900
   필수 표시:     #dc2626 (빨강)                                       ← WCAG AA 통과
   입력 배경:     #ffffff                                              ← 순백, 피로감 최소
   입력 테두리:   #cbd5e1 → focus #6366f1 (인디고)                     ← 명확한 상태 변화
   입력 텍스트:   #0f172a, 14px                                        ← 슬레이트-900 (가독성 최강)
   placeholder:  #94a3b8                                              ← 슬레이트-400 (명확히 구분)
