/* 재개발·재건축 소개 화면(public/index.html, /redevelopment/) 2026-10-10 재디자인.
   사용자 지시 "a/b/c를 잘 섞어서 최고의 사이트를": 세 갈래를 면마다 맡긴다.
   A 밤(저녁의 아파트 입면, 창 하나가 한 세대): 첫 화면·조합 화면·들어가는 길·바닥
   B 큰 숫자(흰 면, 숫자 하나를 크게, 안전주황 한 색): 필요한 까닭·조합원 기능
   C 제도 용지(정보 경로도, 범례·표제란·치수선): 누가 보나·진행 순서·원칙
   색은 lm-tokens.css 변수만 쓴다. 인라인 스타일이 없고, 창 무늬는 facade.js가 만든다(스크립트가 없으면 CSS 무늬). */
