/* 소리노트 — 스타일
   디자인 계획
   - 소재: 좋은 문구(노트 종이)와 필드 레코더(단단한 회색 몸체, 빨간 REC 램프)
   - 레이아웃: 종이가 주인공. 크롬은 조용한 회색, 펜 도구는 왼쪽 세로 레일(펜 없는 손이 닿는 곳),
     녹음기는 아래 왼쪽 '데크'. 세로 모드·폰에서는 레일이 아래 가로 막대가 됨.
   - 색: 잉크 파랑(강조), 녹음 빨강(상태 전용), 종이는 라이트/다크 모두 밝게(잉크 가독성 유지)
   - 글꼴: Pretendard Variable 한 가족. 제목은 굵게·좁게, 숫자는 tabular */
