/* ===========================================================================
   KT 서빙로봇 페이지 전용 (business/robot.html 만 싣는다) — 2026-10-06 리디자인
   - 공통 CSS(style.css · business.css · common-header.css)는 고치지 않고 여기서 덮는다.
   - 토큰·버튼·폼·고정 상담 버튼은 하이오더(css/highorder.css)·소상공인 메인(css/business-index.css)과
     같은 값을 **복사**했다. ⛔ 그 두 파일을 불러오지 말 것 — 공통화는 docs/보류항목.md.
   - 본문은 전부 .rb 범위 안이다. 범위 밖에 쓰는 것은 아래 「페이지 전역」 블록뿐이다.
   - 빨강은 사이트 톤 #E60012. 글꼴은 이 페이지가 싣는 variable 판 'Pretendard Variable'.
   - 제품 사진 배경 --rb-photo-bg 는 KT 사진의 실제 배경색(#F3F5F7)에 맞췄다(지시서 #F2F3F5 와 1~2 차이).
