/* style.css — 1021211 COLOR_BLIND (색각랩)
   출발점: DesignKit kit-lineart (모노라인 · 면 대신 선 · 둥근 모서리 · 원형 아이콘 배지 · 큰 여백 · Inter)
   + 디자인 레퍼런스 notion.so (문서·읽기 중심 — 페이지 아이콘, 속성 행, 콜아웃, 토글, 갤러리 카드)
   → 무채 평면 변형: 순백 / 중립 잉크 계조만. 유채색은 "점묘판·색 견본(검사 대상)" 안에서만 쓴다.
   - 1px 헤어라인 + 14~24px 둥근 모서리 + 알약(pill) 버튼 · 원형 키패드 · 동심원 판 테두리
   - 그림자·블러·그라디언트·글로우·배경 패턴·유채 액센트 없음
   - 도구 화면은 가운데 정렬, 읽기 화면은 좌측 정렬 문서형
   - 배경·선은 R=G=B 중립 회색만 쓴다(판 주변 색 편향 방지) */
