 - 利用 `Big.js` 剥离了流水明细中无意义的尾随零，提升了高精度数据的可读性。
 - 在 `app/dashboard/page.tsx` 的流水明細子表格中，将 `tx.quantity`、`tx.price`、`tx.fee` 的渲染逻辑改为 `new Big(value).toString()`，安全剥离因数据库 `numeric(36,18)` 配置导致的如 `0.041000000000000000` 这类冗余尾随零。
 
+## 盈亏红绿视觉规范 (Task 42c)
+- 依据中文金融习惯（红涨绿跌），规范了盈亏数值的颜色与正负号显示。
+- 移除了 `formatPnl()` 函数及概览行内硬编码拼接的 `+` 号前缀，正收益直接展示数值，负收益保留原生 `-` 号。
+- 统一颜色逻辑：值 `> 0` 应用 `text-red-500`（红色），值 `< 0` 应用 `text-green-500`（绿色），值 `=== 0` 使用默认文字颜色。
+- 括号内的百分比同步遵循相同逻辑，格式如 `$2447.48 (114.20%)`。

 ## 持倉引擎 Native 幣種算法重構 (Task 38)
 - 重構底層盈虧引擎，全面轉向 Native 原生幣種計算，新增浮動/累計盈虧及百分比指標。
 - 徹底分離 Native 與 CNY 計算：單隻股票的成本與盈虧全部改用 Native (原幣種) 進行計算。
