/* Leapinity 뮤직 화면 모양
   - 색·글꼴·버튼·위아래 막대는 lp-brand.css(Leapinity 공통, _leapinity-style 에서 복사)를 써요.
   - 여기는 뮤직에만 필요한 모양. 색은 모두 변수로 써서 밝게·어둡게가 같이 바뀌어요.
   - 사이트 고유 색: 장미(로즈) #db2777 (흰 글자 4.6:1) / 흰 바탕 글자 #be185d (5.6:1 이상) / 어두운 바탕 글자 #f9a8d4
   - style-src 'self' 라서 HTML 에 style="…" 을 쓰지 않아요 (자바스크립트의 el.style.setProperty 는 괜찮아요) */
