/* ── 인쇄 ─────────────────────────────────────────────────────
   화면에서는 완전히 숨기고, 인쇄할 때만 곡의 전체 페이지를 한 장에 한 면씩 깐다.
   악보는 전부 세로(비율 0.685~0.816).

   한 장 높이를 '알아내서' 지정하려 하면 안 된다. vh 는 iOS Safari 가 인쇄 시
   용지가 아니라 화면 뷰포트로 계산하고, mm 절대값은 Safari 가 @page margin 을
   무시하고 자체 여백(약 0.5in)을 쓰는 탓에 넘친다. 둘 다 22장을 44장으로
   만들었다.

   그래서 높이를 아예 지정하지 않고 padding-top 백분율로 만든다. 백분율 패딩은
   '박스 너비' 기준이라, 브라우저가 여백을 얼마로 잡든 인쇄 영역 너비를 따라
   높이가 같이 줄어든다 — 여백을 알 필요가 없어진다.

   129% 는 대칭 여백 M 에서 (용지높이-2M)/(용지너비-2M) 의 하한이다.
     A4     297/210   = 1.414  (M=0 이 최악)
     Letter 279.4/215.9 = 1.294 (M=0 이 최악)
   즉 129% 면 A4·Letter 어느 쪽이든, 여백이 0 이든 20mm 든 박스가 한 장을
   넘지 않는다. Safari 기본 여백(0.5in)에서는 A4 기준 33mm 가 남는다.
   최대 크기보다 약 10% 작게 나오는 대신 용지·여백 추측을 안 한다. */
