/* ==========================================================================
   앱셸(화면스크롤) — 문서 전체 스크롤 대신 "본문 래퍼만" 내부 스크롤.
   효과: 헤더·푸터 항상 고정 + 문서 스크롤바 소멸(콘텐츠 폭 불변) → 페이지 이동 시
         헤더/로고가 좌우로 밀리는 현상까지 차단. 홈과 동일 구조.

   [안전 규칙 1] body 에 overflow:hidden 을 걸면 "스크롤러로 지정된 래퍼"가 반드시 있어야 한다.
   래퍼를 모르는 페이지에 걸면 화면 밖 내용에 접근 불가가 되므로, 아래 목록의 래퍼를
   body 직속으로 가진 페이지에만 :has() 로 선별 적용한다. 목록에 없으면 자동 폴백(문서 스크롤).

   [안전 규칙 2 — 매우 중요] 인쇄 시에는 앱셸을 반드시 해제한다.
   height:100vh + overflow:hidden 이 인쇄에 그대로 적용되면 "첫 화면 1장"만 인쇄되고
   나머지 내용이 통째로 잘린다(보고서·장비목록 인쇄가 깨짐). 아래 @media print 로 원복.

   모달은 position:fixed 라 플렉스 흐름에서 빠져 영향 없음.
   푸터는 고정 대신 플렉스 마지막 자식으로 되돌림. 홈은 shell.css 미로드라 무영향.
