/* 모든 페이지의 공통 스타일(리팩토링 P3-8에서 main.css를 나눴다).
 *
 * base.html과 공용 조각(헤더, 계정·설정 메뉴, 하단 탭, 푸터)의 요소, 공용 스크립트가 만드는 요소(auth.js의
 * 로그인·탈퇴 창과 알림), 여러 페이지가 같이 쓰는 부품(상품 카드·목록·페이지 번호, 검색창·필터 칩, 상품 추가 요청
 * 버튼과 창)의 스타일이다. 한 페이지만 쓰는 스타일은 그 페이지 파일(home.css 등)에 있고, 페이지는 이 파일 다음에
 * 제 파일을 싣는다(base.html의 page_stylesheet).
 *
 * 규칙 순서는 main.css 그대로다. 페이지 파일이 뒤에 오므로 명시도가 같으면 페이지 규칙이 이긴다.
 * 앱 모드 블록은 이 파일의 맨 끝에 둔다.
