/* 365일 아동의 날(국가아동권리보장원 기념일 홈페이지) case study: every rule is scoped to .nc-page / .nc so the shared header, contact and footer stay untouched.
   Night rooms take the navy of the 「365일 아동의 날」 logo; white and paper rooms follow the campaign art.
   Emphasis follows the color rule of the page itself: yellow is a highlighter under ink text, never text on white. */
