   99. iOS 앱(WebView) 안전영역 — 상태바(노치) 회피
   ----------------------------------------------------------------
   iOS 앱은 capacitor.config.json 의 ios.contentInset = "never" 로
   동작한다(설정 시 상하단 빈 여백이 생기는 문제 해결).
   그 결과 WKWebView 가 상태바 뒤까지 확장되므로, 웹이 직접
   safe-area-inset-top 만큼 아래로 내려야 툴바가 가려지지 않는다.

   ★ safe-area-inset-* 는 iOS 에서만 계산된다.
     데스크톱/안드로이드/일반 브라우저에서는 전부 0px 이므로
     이 블록은 어떤 환경에서도 기존 화면을 바꾸지 않는다.
   ================================================================ */

/* 상태바(노치) 회피 — 상단 툴바는 위 33번 블록의 height 규칙으로 이미 처리된다.

/* 상단 고정 요소(모달/드롭다운)도 상태바 아래에서 시작 */

  max-height: calc(70vh - env(safe-area-inset-top, 0px));
