   Oruli 와이어프레임 킷 (_wireframe-kit.css)
   ------------------------------------------------------------
   목적: KB→화면설계→[와이어프레임]→디자인 파이프라인의 ③단계.
   원칙: 회색·박스·저해상도. 하이파이 Figma와 혼동되지 않도록
        브랜드 색·이미지·그림자를 쓰지 않는다. 구조(뼈대)만 담는다.
   대상: 375×812 모바일. 실제 디자인의 최종 테마는 '다크'다
        (와이어프레임은 관례상 밝은 회색으로 구조만 본다).
