/* 개편(mood-A v3) 헤더 — 아직 개편 전인 운영 페이지(현재 /privacy-policy)에 새 헤더만 얹기 위한 범위 한정 스타일. 2026-10-02
   원본: design/mockups/mood-A/v3/css/style.css 헤더 규칙(.hdr · .mnav · .btn · .ext · .hdr__tag · .hdr__dot). 기존 webflow.css · style.css와 섞이지 않게 .v3hdr 아래로 묶었다.
   첫 화면 이미지가 없는 페이지라 화면 위에 떠 있지 않고 위에 붙는 검은 띠(sticky)로 둔다. 동작은 /js/v3-header.js */
