+
+## 用户需求
+
+新增一个"AI作文原图批改"功能页面，用户上传英语作文图片后，系统调用指定 API 对图片进行智能批改，并将批改后的结果图片展示在页面上。
+
+## 产品概述
+
+在现有 AI 英语学习辅助平台中，新增作文批改页面（路由 `/essay-correction`），与首页卡片联动。用户上传手写英语作文图片，系统将图片转为 Base64 后调用批改 API，等待返回批改后的图片 URL，最终在页面上对比展示原图与批改结果图。
+
+## 核心功能
+
+- **图片上传**：支持点击选择或拖拽上传图片文件（JPG/PNG），上传后预览原图
+- **API 调用**：将图片转为 Base64，携带固定提示词调用 `POST https://grsai.dakka.com.cn/v1/draw/nano-banana` 接口
+- **批改结果展示**：接口返回后，将批改结果图片渲染到页面，支持与原图对比查看
+- **状态反馈**：上传中、批改中、批改完成、批改失败等状态的加载动画与提示
+- **重新批改**：支持清空结果、重新上传图片进行新一轮批改
+- **返回首页**：顶部导航栏提供返回按钮，风格与 Speaking.vue 保持一致
+
+## 技术栈
+
+- **框架**：Vue 3 (Composition API `<script setup>`) + Vite，与现有项目完全一致
+- **路由**：Vue Router，新增 `/essay-correction` 路由
+- **样式**：Scoped CSS，复用现有 CSS 变量（`--card-bg`、`--card-border`、`--accent-1`、`--text-primary`、`--text-secondary`）和深色玻璃拟态风格
+- **HTTP 请求**：原生 `fetch` API，与现有项目保持一致（无额外依赖）
+
+## 实现方案
+
+### 核心流程
+
+1. 用户选择/拖拽图片 → FileReader 读取为 Base64 字符串 → 预览原图
+2. 点击"开始批改" → 构造请求体（Base64 放入 `urls` 数组）→ `fetch` POST 请求
+3. 接收响应 → 解析返回的图片 URL → `<img>` 标签渲染批改结果
+4. 错误处理：网络异常、API 错误码、图片加载失败均给出友好提示
+
+### API 请求参数设计
+
+```
+prompt: "请对这篇英语作文进行批改，标注语法错误、拼写错误和表达不当之处，并给出修改建议"
+model: "nano-banana-pro"
+aspectRatio: "auto"
+imageSize: "1K"
+shutProgress: true
+webHook: ""
+```
+
+### 关键技术决策
+
+- **Base64 转换**：使用 `FileReader.readAsDataURL()` 读取图片，截取 `base64,` 后的纯 Base64 字符串传入 `urls` 数组
+- **图片大小限制**：前端限制上传图片不超过 10MB，避免 Base64 字符串过大导致请求失败
+- **响应结构处理**：API 返回结构待运行时确认，优先尝试 `response.data`、`response.url`、`response.imageUrl` 等常见字段，并做防御性处理
+- **加载状态**：批改期间禁用上传和提交按钮，显示旋转动画，防止重复提交
+
+## 架构设计
+
+```mermaid
+graph TD
+    A[HomePage.vue card-3] -->|router.push| B[/essay-correction]
+    B --> C[EssayCorrection.vue]
+    C --> D[图片上传区域]
+    C --> E[批改控制区]
+    C --> F[结果展示区]
+    D -->|FileReader| G[Base64转换]
+    G --> E
+    E -->|fetch POST| H[nano-banana API]
+    H -->|返回图片URL| F
+```
+
+## 目录结构
+
+```
+src/
+├── views/
+│   └── EssayCorrection.vue   # [NEW] AI作文批改页面主组件
+│                               # 包含：图片上传（拖拽/点击）、原图预览、
+│                               # API调用逻辑、批改结果图片展示、
+│                               # 状态管理（idle/uploading/processing/done/error）、
+│                               # 返回导航栏，风格与Speaking.vue保持一致
+└── router/
+    └── index.js              # [MODIFY] 新增 /essay-correction 路由，
+                              # import EssayCorrection 并添加到 routes 数组
+
+src/views/HomePage.vue        # [MODIFY] 将 features 数组中 id:3 的 card-3
+                              # route 字段从 null 改为 '/essay-correction'
+```
+
+## 实现注意事项
+
+- **CSS 变量复用**：Speaking.vue 中使用了 `var(--card-bg)`、`var(--accent-1)` 等全局 CSS 变量，EssayCorrection.vue 同样直接使用，无需重复定义
+- **图片展示布局**：批改完成后采用左右对比布局（原图 / 批改结果），移动端降级为上下堆叠
+- **文件类型校验**：accept 限制为 `image/jpeg,image/png,image/jpg`，并在 JS 层二次校验 MIME 类型
+- **Authorization 配置**：API Key 以常量形式定义在组件顶部，与现有项目中 API Key 的管理方式保持一致
+
+## 设计风格
+
+延续现有项目的深色玻璃拟态（Glassmorphism）风格，与 Speaking.vue 保持视觉一致性。
+
+### 页面布局（从上到下）
+
+**顶部导航栏**
+左侧返回按钮（箭头图标 + "返回"文字），中间标题"AI 作文原图批改"，风格与 Speaking.vue 的 `.nav-bar` 完全一致。
+
+**上传区域**
+居中大卡片，虚线边框（`rgba(236,72,153,0.3)`，对应 card-3 的粉色主题），内含上传图标、"点击或拖拽上传作文图片"提示文字、支持格式说明。拖拽悬停时边框高亮为粉色渐变，背景微亮。上传后区域缩小为原图预览缩略图，右上角显示"重新上传"按钮。
+
+**操作区**
+"开始批改"主按钮，使用 card-3 的粉色渐变（`#ec4899 → #db2777`），宽度自适应，批改中显示旋转加载动画 + "批改中..."文字，禁用状态半透明。
+
+**结果展示区**
+批改完成后以左右对比卡片展示：左侧"原图"、右侧"批改结果"，每张图片下方有标签说明。图片以 `object-fit: contain` 填充，支持点击放大查看（简单 overlay 实现）。移动端改为上下排列。
+
+**错误提示**
+红色半透明提示条，显示错误信息，可手动关闭。
