/* 참모 요구사항정의서 뷰어(/command/requirements.html). 공개 홈과 같은 라이트 세계다.
   바탕은 한 단 낮은 책상 면(surface-subtle), 그 위에 흰 쪽 한 장씩. 네이비는 표지와 부 표지에만 깔고,
   금색은 네이비 위의 '지금 여기' 표지(부 번호 밑줄) 한 곳에만 쓴다. 코발트는 링크와 현재 위치에만.
   쪽은 1280×800 판으로 짜고 창에 맞춰 줄인다(requirements.js). 좁은 창·스크립트 없음에서는 판을 풀어
   위에서 아래로 흐른다. 값은 전부 lm-tokens.css 변수다(hex 없음). CSP 때문에 인라인 스타일이 없다. */
