+## SKU选择器价格显示错误修复
+- **文件**: `src/components/business/SkuSelector/index.tsx`
+- **问题**: 商品详情页价格显示 ¥1019，但点击"立即购买"后SKU弹窗显示 ¥2519
+- **根因**: `currentPrice` 计算式中 `salePrice` 优先级高于 `price`。ShopGoods 模型中 `price`=实际售价(1019)，`salePrice`=市场/原价(2519)。当 SKU 未选中时回退到 product 级别，错误地优先取了 salePrice
+- **修复**:
+  1. 第190行: `currentPrice` 优先级改为 `selectedSku?.price || selectedSku?.salePrice || product?.price || product?.salePrice`
+  2. 第160行: 单规格 fakeSku 的 price 字段同样修正为 `product.price || product.salePrice`
