// 요일별 막대 요약 — 칸은 grid-template-columns: repeat(7, 1fr) 로 정확히 균등 분할한다
// (flex: 1 1 0 위에 scaleX 로 채우면 BD19 가 탭 인디케이터로 오해한다 — 254-05 계열).
// 막대는 아래 변에 붙어 자라는 것이라 transform-origin 을 bottom 에 두고 scaleY 로만 키운다.
// 목표선을 넘은 막대는 색이 갈리지만 그 위에 숫자를 늘 적어 두므로 색 없이도 읽힌다.
// 미리보기(.is-demo)는 왼쪽 막대부터 차례로 자라고, 사람이 칸을 누르면 그 요일 수가 올라간다.
