/* apps/1to50/style.css — 1to50: 밝은 하늘색 놀이판 (흰 바탕 + 파랑 타일 두 단계 + 산호색 강조).
 * 모바일 한 줄(--app-width 480px). 글꼴은 언어 파일 fonts → :root 변수(--font-display 등, 생성기가 이 파일 뒤에 둔다).
 * 숫자(타일·HUD·결과)는 모든 언어에서 Fredoka(--font-num) — 언어별 fonts.css 에 함께 불러온다.
 * 클래스 앞머리는 ot-(공통 컴포넌트의 mg- 와 겹치지 않게). 공통 타이틀 바(G.topBar)·끝 화면(data-mg-end)은 --mg-* 변수로만 색을 맞춘다.
 * 판은 DOM 격자(.ot-board > .ot-cell 버튼 25개) — 1..25 는 옅은 파랑, 26..50 은 짙은 파랑, 비면 흐린 칸.
