/* =====================================================================
   공통 헤더 — 메인(스탠드얼론 v2)과 서브(buly 스킨) 가 함께 쓴다.
   ---------------------------------------------------------------------
   이 파일이 헤더의 유일한 정의다. main-v2.css / sub-v2.css / buly 스킨에
   헤더 규칙을 다시 넣지 말 것 — 두 벌로 갈라져 있던 것을 합친 결과다.

   클래스는 전부 `lu-` 접두사다. buly 스킨의 .nav/.top_menu/.lnb/.api_key 를
   물려받지 않으려고 새 이름을 썼다 — 스킨 css 를 건드리지 않아도 충돌이 없다.

   토큰을 자체 정의하므로 main-v2.css 없이도(=서브 페이지) 그대로 동작한다.
