/* 보도블럭보수업체(임팩트) — 차콜 앤 오커 디자인 시스템
   - Charcoal(#23262b)/Ochre(#b5762c) — 아스팔트 어두운 톤 + 줄눈 모래·시공 안전색 반영
   - Roots(세면대대리석) 스톤그레이 시스템의 베리에이션: 단일 그레이 톤 대신 차콜+오커 대비 배색,
     히어로는 46/54 분할 대신 풀블리드 슬라이드쇼 + 불투명 카드, radius를 살짝 더 각지게(8/14)
   - 보조 배경: 웜 베이지 대신 쿨 슬레이트미스트(#e9edf1)로 변경 — 오커 액센트와 대비되는 차가운 톤
   - 폰트: Pretendard (Gmarket Sans에서 변경 — 더 깔끔하고 가독성 높은 톤으로) */
