/* /ai-courses/ 전용 스타일 (docs/superpowers/2026-10-28-ai-courses-online.md D9·D12·D13)
   D12 레이아웃(장부·2×2 카드·행렬·FAQ details)은 그대로 두고, D13에서 사이트 크롬·색·서체·면·단추를
   wenvidia.com 메인(신툴즈) 체계로 다시 입혔다. 토큰은 src/index.css·SiteChrome.css 실측값과 같다.
   공용 seo-pages.css 위에 얹으므로 모든 규칙을 body.aic-page 아래로 좁혔다(신툴즈의 .container·.button 등
   같은 이름이 공용 CSS와 부딪히지 않게). 되돌릴 때는 D13 커밋 하나를 되돌린다. */
