/* ===== 세면대대리석리폼(Roots) — 스톤 그레이 앤 웨이퍼 디자인 시스템 =====
   design.md(MSR: 네이비+브라스, 각진) 기반 베리에이션:
   - Regent Gray(#899CA8)/Wafer(#DFD3CE) 컬러 컨셉 — 실제 대리석의 그레이/베이지 톤을 그대로 반영
     (두 색은 서로 대비가 낮아(1.94:1) 텍스트/배경 페어로 직접 쓰지 않고, 프라이머리는 Regent Gray를
     어둡게 가라앉힌 슬레이트, 액센트는 Regent Gray를 버튼 대비 기준(4.5:1 이상)까지 톤다운해 도출)
   - 각진(radius:0) 대신 부드러운 라운드(대리석 모서리 가공 느낌)
   - 폰트 Pretendard → Paperlogy
   - 섹션 순서/그리드 배치 변형 */
