/* apps/memory/style.css — 카드 짝 맞추기: 할로윈 밤 (짙은 보라 바탕 + 호박 주황 + 연두 강조, 카드 뒷면 = 보라 거미줄 무늬, 앞면 = 크림색 + 이모지).
 * 모바일 한 줄(--app-width 480px). 글꼴은 언어 파일 fonts → :root 변수(--font-display 등, 생성기가 이 파일 뒤에 둔다).
 * 숫자(HUD·결과)는 모든 언어에서 Fredoka(--font-num) — 언어별 fonts.css 에 함께 불러온다.
 * 클래스 앞머리는 mm-(공통 컴포넌트의 mg- 와 겹치지 않게). 공통 타이틀 바(G.topBar)·끝 화면(data-mg-end)은 --mg-* 변수로만 색을 맞춘다.
 * 판은 DOM 격자(.mm-board > .mm-card 버튼) — 열 수는 JS 가 grid-template-columns 로, 판 폭은 난이도(data-level)별로 화면 높이에 맞춘다.
