/* ==========================================================================
   바느질공작소 NEEDLEWORK WORKSHOP — 브랜드 아이덴티티 케이스
   강디자인

   설계 근거
   - 승인 컨셉 원문은 이 마크를 "한국 전통의 빗살과 천 조각의 매칭"이라 적고,
     둥근 외곽을 "원(Circle)안에 구성함으로 모두가 하나되는 협력과 상생의 한국적 두레가치"
     라고 밝힌다. 바늘귀가 아니다. 그래서 지면이 '천'이고 이음매가 있다.
   - 바탕 #2a3861 은 승인 가이드북 표지에서 잰 값이다. 지어낸 남색이 아니다.
   - 색 수치는 전부 실측값이다. 규정의 원본은 CMYK 이고 RGB 는 렌더 실측값임을 밝힌다.
   - 마크를 기울이거나 돌리지 않는다. 승인 09 사용금지 06 「각도를 변형하여 사용한 경우」.
