/* ===========================
   development.css — homepagerenewal/development.html 시안을 개발 페이지(/development/)에 이식
   치수/색은 시안 style.css의 DEVELOPMENT PAGE 섹션(462~553행)과
   공용 FAQ 규칙(.c-faq/.faq-* 435~446행)을 따른다.

   시안은 전역 :root 변수(--dev/--dev-deep/--navy/--orange/--white/--ink/--max)와
   .wrap/.c-head/.c-title에 의존한다. 다른 페이지 이식과 동일하게 .dev-page 스코프에서 자체 정의한다.
