/* 조합원 화면과 관리 화면(/redevelopment/tour/). 시연 무대 한 장: 위 막대 · 장면 흐름 · 두 화면 · 아래 줄이 화면 높이(100dvh)를 꽉 채운다.
   무대는 레일 네이비 면이고, 그 위에 어두운 테두리의 휴대전화와 브라우저 창 두 개만 밝게 뜬다. 금색은 네이비 위에서만 쓴다
   (지금 장면 표시와 두 화면을 잇는 실). 코발트는 주 행동 하나(다음 장면)와 화면 안 고리다.
   두 틀 안은 같은 출처의 실제 화면(iframe)이다. 화면은 제 크기(휴대전화 390×844, 관리 화면 1280px 폭)로 그리고 배율만 바꾼다
   (tour.js가 CSSOM으로 --rt-k·--rt-ka·--rt-adm-w·--rt-adm-h를 바꾼다. 인라인 스타일은 CSP로 막혀 있다).
   장면 설명 목록·직접 열어 보기·바닥은 무대 아래 웜 페이퍼에 둔다(소개 화면 landing.css의 단추·바닥을 쓴다).
   값은 lm-tokens.css 변수다(이 파일에 hex를 두지 않는다). */
