   (주)다채움 CI · BOOM COFFEE BI — 브랜드 아이덴티티 케이스
   강디자인

   읽는 사람 — 의뢰를 검토하는 사업주다. 이야기로 쓴다.
   실측 층(색 수치·곡선)은 CASE_NOTES 에만 둔다.

   설계 근거
   - 지면 #42341D 는 붐커피 BS-04 색상규정의 BOOM BROWN 실측값이다
     (Process Color C66 M72 Y100 K43). 포트폴리오에 갈색 바탕이 없다.
     다채움 쪽 초록 #A3D71D 계열은 이웃사촌상조 지면과 겹쳐 쓰지 않았다.
   - 이 케이스만 회사(다채움)와 제품(붐커피) 두 권이다. 한 권으로 묶여 납품됐고
     PACKAGE 표지에 두 마크가 나란히 찍혀 있어 한 케이스로 묶었다.
   - 마크의 형태·비례·색은 건드리지 않았다. 모션 01 은 승인 원본을 통째로
     올리고 마지막에 한 번 더 덮어 끝 프레임을 승인 조합에 고정한다.
   - 뺀 것: CHARACTER · PACKAGE 표지 두 지면(출처 불명 스톡 사진),
     3D 합성 목업 지면 일곱(배경 출처 불명), 배너(효능 문구),
     폴더의 견적·계약·설문·카카오톡 캡처 · 타사 규격도면 전부.
   - 지면은 A4 가로 실치수라 크롭마크가 없다. 잉크 bbox 로만 잘랐다.
