 - **Buy 模式 Amount 区**：无论余额是否充足，均显示 Amount 标签、Balance、金额输入、+$1/+$20/+$100/Max 快捷按钮（桌面端、嵌入弹窗、移动端弹窗一致）
 - 余额不足时 Buy 显示 Deposit 按钮
 - 25%/50%/Max 快捷份额
+- **Sell 模式 UI 优化**：
+  - Shares 标签与 Max shares 提示同行显示（`max-shares-inline`）
+  - 输入框独占一行（`shares-input-wrapper`）
+  - 25%/50%/Max 按钮独立一行（`sell-shares-buttons`）
+  - 整体布局更清晰：`Shares          Max: 2` → `[输入框]` → `[25%][50%][Max]`
 - 调用 market API 下单、Split、Merge
 - **合并/拆分成功后触发事件**：`mergeSuccess`、`splitSuccess`，父组件监听后可刷新持仓列表
