/* 따릉이 대여소 군집 관제 화면
   ------------------------------------------------------------------
   관리자 템플릿이 아니라 "운영관제 콘솔" 인상을 목표로 한다.
   - 지도가 화면의 가장 큰 면적을 차지하고, 가중치 패널과 군집 요약이
     양옆에서 지도를 보조한다.
   - 색은 배경(먹색) + 군집 4색 + 강조 1색으로 제한한다.
   - 군집은 색만으로 구분하지 않는다. 번호와 이름을 항상 함께 쓴다.
   - 애니메이션은 상태 전환을 알리는 최소한만 쓴다(0.12s 이내). */
