 * ecb-ui.css — 교육문화비즈니스 네트워크 공개 페이지 디자인 시스템 (단일 소스)
 *
 * 이 파일이 공개 페이지(index/about/services/projects/membership/contact/
 * privacy/terms/404)의 유일한 시각 디자인 소스다. 라이트 SaaS 스타일: 흰 배경 +
 * 연한 회색 표면, 얇은 1px 경계선, 12~16px 라운드 카드, 오렌지 단일 액센트,
 * 다크(#111) 히어로 한 곳만, 여백 넉넉, 아이콘은 단순 라인.
 *
 * 기존 JS(home.js, public-pages.js, public-operations.js,
 * landing-interactions.js, keyword-guide-chat.js, onboarding.js)가 참조하는
 * id·class·data-속성은 전부 그대로 두고, 이 파일은 그 클래스들에 새 스타일을
 * 입힌다. 새 콘텐츠(아이콘 타일, 통계 카드, 단계, 배너)만 `.ecb-` 접두사 클래스를
 * 새로 쓴다. onboarding.css는 이 파일 다음에 로드되어 회원가입 전체화면 단계를
 * 최종적으로 덮어쓴다.
