/* 기능 5·6(PDF 합치기 · PDF 나누기 · 무료) — 모양 (설계서 4-7 보기 규칙 · 4-8 모바일 · 4-9 접근성)
   색은 기존 토큰(style.css :root — 남색·금색·초록·바탕·카드)을 그대로 쓰고, 묶음 색 띠 전용 새 색 셋(#2F6FB3·#7A4E9C·#1F7A8C)만 더한다
   (띠는 pt-ui-board.js 가 칠한다 · 색만으로 가르지 않고 늘 「파일 1」 글자를 함께). 글자 크기는 기존 뿌리 크기를 따른다(새로 키우거나 줄이지 않음).
   ⛔ 남의 배치·색·아이콘을 옮기지 않는다 — 이 화면은 기존 V1.3 카드·칸의 연장이다(설계서 3-2 · 3-4). */
