/* ============================================================
   연세치과 二代記 — 프론트 v0.5 「페이지 전환형 양면 레이아웃」
   레퍼런스: 1983sam.com 실화면 구조
   · 왼쪽 = 아카이브 지면(따옴표 제목 + 옛 사진 + 연도 캡션) — 확정
   · 오른쪽 = 순백 콘텐츠 "페이지". 스크롤 원페이지가 아니라
     메뉴/탭/차례 클릭으로 페이지가 하나씩 전환(해시 라우팅),
     전환 시 왼쪽 지면이 장 넘기듯 함께 교체
   · 상단바: 로고 · 현재 페이지명(▾ 드롭다운) · 네이버예약 · 전체메뉴
   · 이미지 속 캘리 문구는 화면 텍스트로 반복하지 않음
   · 1024px 미만: 지면 사진이 활성 페이지 상단에 인라인 배치
