//       node _design-test/apply-vue-colors.js --write  （真写）
//
// 为什么不能只做单色 1:1 替换：
//   1) ECharts 的 10 色分类色板若逐色映射，会与已有的 #3b82f6 / #ef4444 撞色，序列失去区分度
//   2) 同一个渐变串 linear-gradient(135deg,#f08060,#d9481c) 同时用于「房源等级 A」和「客源热度 H」，
//      但 A 现在要改成品牌金、H 仍是红 —— 必须按选择器区分
// 所以规则分两类：先按「选择器/整串」精确处理，再对剩余单色做通用映射。
