/* 인터랙티브 데모 페이지 (/demo, /demo/*-demo) 전용 스타일.
 *
 * 레이아웃은 목업(Demo Launcher.dc.html)을 따르되 색·폰트는 사이트 토큰을 쓴다.
 * 포인트 컬러는 브랜드 오렌지 #ff9012 지만, 흰 배경 위 작은 글자에는 대비가
 * 모자라므로(2.1:1) eyebrow·링크 같은 텍스트에는 어두운 변형 --demo-accent-ink
 * 를 쓴다. 채움(버튼 배경·불릿·재생 아이콘)에만 원래 오렌지를 쓴다.
 *
 * 공통 navbar/footer 는 jQuery .load() 로 들어오므로 여기선 건드리지 않는다.
