/* =================== 디자인 토큰 ===================
 * 색은 리터럴로 쓰지 말고 여기 정의된 토큰을 쓴다.
 *
 *  --accent*  : 모드(N2·N1·JLPT·BJT)에 따라 바뀌는 강조색.
 *               예전에는 이 색 하나 바꾸려고 body.theme-* 규칙 69개를 복제해 뒀었다.
 *  --success* : "정답·완료"를 뜻하는 초록. 모드가 바뀌어도 초록이어야 하므로 액센트와 분리했다.
 *  --danger*  : 오답·경고
 *  --ink-*    : 글자색 단계 (진함 → 흐림)
 *  --line-*   : 경계선 단계
 *  --surface* : 면(배경) 단계
 *
 * ink/line 단계는 기존 CSS 에 흩어져 있던 값을 "그대로" 옮겨 둔 것이라
 * 서로 거의 같은 단계가 몇 개 섞여 있다(#444/#555, #ddd/#e0e0e0 등).
 * 단계를 줄이는 건 눈에 보이는 변화를 만드는 별도 결정이라 여기서는 손대지 않았다.

 *
 *  - 홈(#level-overlay · #jlpt-sub-overlay): 밝고 깔끔한 카드형. 다크 모드는 --hm-* 토큰만 바꾼다.
 *  - 학습 화면(헤더·탭·단어장·플래시카드): 밝은 회백색. 다크 모드는 --sk-* 토큰만 바꾼다.
