   xmaker-site.css — xMaker 공식 소개 일반페이지 공용 스타일
   ---------------------------------------------------------
   · 페이지별 CSS(page_01.css …)에서 @import 로 불러 쓴다.
   · 색은 전부 활성 템플릿(dark_blue)이 :root 에 심어 둔 변수를
     그대로 쓴다 → 다크모드를 상속받고, 헤더의 라이트/다크
     토글([data-theme="light"])에도 자동으로 따라간다.
       --bg / --card-bg / --card-bg2 / --text-main / --text-muted
       --border / --primary / --secondary / --site-width
   · 모든 클래스는 xm- 접두사를 쓴다. 테마의 .card 등에는 본문
     스크롤 애니메이션이 이미 걸려 있어 이름이 겹치면 서로 간섭한다.
   · 본문은 .post-content(= .container 안, 최대 --site-width) 안에
     들어가므로 헤더/푸터/사이트 폭은 여기서 건드리지 않는다.
