   - 토큰(:root)은 B 의 css/base.css 가 정한다 — 여기는 var() 로만 쓴다. 클래스 접두어 dn-(A 몫: §18).
   - 책은 물건이라 라이트/다크 테마를 따르지 않는다(바탕은 언제나 어두운 책상).
   - 쪽 안의 크기는 pu(쪽 폭 1000 기준) — --dn-s(= 쪽 CSS 폭 / 1000)를 곱해 px 로.
   - 종이 · 가죽 질감 변수(--dn-lines · --dn-stain-0..4 · --dn-noise · --dn-leather · --dn-rough)는 page.js 가 .dn-book 에 넣는다(쪽마다 --dn-stain · --dn-sx/sy).
   - 가로로 든 폰(높이 ≤ 540 · 가로) = 툴바는 왼쪽 세로 레일 · 머리글과 쪽 이동은 아래 한 줄 · 바닥글은 첫 화면 밖(맨 아래 블록).
