/* 워드픽 랜딩(설명) 페이지 — 고객 시안 rev1.4 (docs/references/client/wordpick-site_rev1.4.html, #318).
 *
 * 시안 CSS 를 옮기면서 바꾼 것:
 * - 다크 모드 규칙은 뺐다 — 사이트 다른 화면이 지원하지 않는다.
 * - 요금제 카드·비교표는 공용 plans.css, FAQ 문답은 faq.css(둘 다 요금제 페이지와 같은 부품). 꼬리말은 footer.css.
 * - 서체는 사이트 공통 Pretendard, 로고 색은 디자인 규칙(design-system.md §2)의 값.
 * - 변수 --surface·--line·--ink 는 plans.css 와 이름이 겹쳐 --lp-* 로 바꿨다.
 * - 넓은 여백과 폭은 맨 아래 "시안 대비 보정" 에서 줄이고 맞춘다.
