/* apps/randnum/style.css — 랜덤 숫자 뽑기: 연보라 모눈종이 + 진남보라 잉크 + 플립 보드(스플릿 플랩) 숫자 릴 + 라임·바이올렛 포인트.
 * 둥근 흰 카드 + 부드러운 보라 그림자(dice·lotto 의 어긋난 굵은 그림자와 다르게). 모바일 한 줄(--app-width 480px).
 * 숫자는 언제나 JetBrains Mono(고정폭), 제목·버튼은 언어 파일 fonts → :root 변수(--font-display 등, 생성기가 이 파일 뒤에 둔다).
 * 공통 타이틀 바(G.topBar)·끝 화면(data-mg-end)은 --mg-* 변수로만 색을 맞춘다.
