/* B2C 销售看板（2026-09-24）：飞书表格《B2C 通途出单》→ 每个产品近 7/30/90 天。
   配色规矩（dataviz）：件数/份额这类「多少」用同一色相由浅到深（--chart-seq-*）；
   店铺是「谁」，四家固定各占一色（跟实体走、不跟名次走）：赞拓 chart-1 · 查实米 chart-6 · 田背山 chart-4 · ITOP不开票 chart-5
   （这四个 token 两两在三种色觉缺陷模拟下 ΔE≥9.3、正常视觉 ≥15.4，是 tokens.css 八个类别色里唯一全过的四元组；chart-2 蓝与 chart-4 紫在红绿色盲下只差 2，不能同台）；
   涨跌只用 chart-positive / chart-negative；文字永远用文字色，不穿数据色。 */
