/*
 * The EarlyOffice document pages — 통합약관 /terms/, 개인정보 처리방침 /privacy/ · /en/privacy/, 업데이트 내용 /updates/,
 * 오픈소스 라이선스 /licenses/, 404 (2026-11-02). Their frame is site/office/pages.py doc_page(); their words are not
 * touched by this sheet or that frame.
 *
 * The look is earlyadopter.io's (earlyadopter_homepage site/assets/site/ea.css): family colours only (static/family.css,
 * a copy of the family file generated from early-family tokens/family.json), ink buttons, hairlines, coral and orange
 * only as the brand's own marks. Unlike the always-dark EarlyOffice page, these pages are for reading and follow the
 * system's light or dark setting.
 *
 * Faces (사용자 "그렇게 해줘봐", 11/2): MaruBuri for what is read — titles, section headings and the running text of the
 * terms, the privacy policy and the release notes; Pretendard for what is pressed or scanned — buttons, menus, header,
 * footer, contents list, tables, numbers, dates, captions, small labels. The licence page keeps only its titles in
 * MaruBuri. Both faces are subsets served from this site (site/office/fonts.py, SIL OFL 1.1); when they cannot be
 * fetched the text falls back to Pretendard, then the system's own face, and stays readable. Running text in MaruBuri
 * is 17px with loose leading (small serif text looks thin on Windows).
