/**
 * D41: 模板区剩余硬编码色收编
 *
 * 覆盖三类模板硬编码：
 *   A) 组件属性色值（RadarChart gridColor/labelColor、progress backgroundColor、switch color）
 *      → 绑 data/computed（BrandColors）
 *   B) 模板表达式字符串拼接里的 hex（';color:#fff'、conic-gradient(#F97316 …)）
 *      → 拼接 BrandColors 值（data 属性）
 *   C) placeholder-style / 兜底色字面量 → 绑定 data 字符串
 *
 * 用法: node scripts/d41-template-hex-bind.js [--dry]
