/* apps/sweeper/style.css — 지뢰찾기: 레이더 화면 (짙은 청록 밤 + 격자 + 주황 경고색·민트 안전색).
 * 모바일 한 줄(--app-width 480px). 글꼴은 언어 파일 fonts → :root 변수(--font-display 등, 생성기가 이 파일 뒤에 둔다).
 * 클래스 앞머리는 tf-(공통 컴포넌트의 mg- 와 겹치지 않게). 공통 타이틀 바(G.topBar)·끝 화면(data-mg-end)은 --mg-* 변수로만 색을 맞춘다.
 * 판은 DOM 격자(.tf-board > .tf-cell 버튼) — 칸 크기는 sweeper.js 가 --cell 변수로 정한다.
