/* 색은 모두 :root 토큰으로 정의한다. 차트(ECharts)도 렌더링할 때 같은 토큰을 읽는다.
   플랫폼 색: YouTube = 범주 1(파랑), X = 범주 2(주황), Instagram = 범주 3(청록).
   dataviz 검증기로 밝은·어두운 모드 모두 3색 전체 쌍을 통과한 조합이다.
   수익원 색: 범주 4–7(노랑·자홍·초록·보라) — 플랫폼 색과 겹치지 않게 다음 슬롯을 쓴다. 인접 쌍 검증 통과,
   밝은 모드의 노랑·자홍은 배경 대비 3:1 미만이라 범례와 표 보기를 함께 둔다.
   증감(민감도) 색: 발산 쌍 파랑(이익 증가) ↔ 빨강(이익 감소). */
