Refactor frontend to Vue 3 + Vite + Pinia + Cypress E2E

- Replace single-file 8441-line HTML with Vue 3 SPA
- Pinia stores: auth, oils, recipes, diary, ui
- Composables: useApi, useDialog, useSmartPaste, useOilTranslation
- 6 shared components: RecipeCard, RecipeDetailOverlay, TagPicker, etc.
- 9 page views: RecipeSearch, RecipeManager, Inventory, OilReference, etc.
- 14 Cypress E2E test specs (113 tests), all passing
- Multi-stage Dockerfile (Node build + Python runtime)
- Demo video generation scripts (TTS + subtitles + screen recording)

+# doTERRA 精油配方计算器
+
+精油配方成本计算、配方管理、配方卡片导出工具。
+
+## 功能
+
+- **配方查询** - 搜索配方，按名称/精油/标签筛选，分类浏览
+- **配方编辑** - 可视化编辑精油成分、滴数，自动计算成本
+- **容量换算** - 支持单次/5ml/10ml/30ml 容量，自动稀释比例换算
+- **智能粘贴** - 粘贴文本自动识别精油名称和滴数（支持模糊匹配、同音字纠错）
+- **配方卡片** - 生成精美配方卡片图片，支持中英双语，品牌水印
+- **个人配方** - 保存私人配方，记录使用日记
+- **精油库存** - 标记已有精油，自动推荐可做配方
+- **收藏系统** - 收藏喜欢的配方，快速访问
+- **商业核算** - 项目成本利润分析（企业用户专属）
+- **Excel 导出** - 批量导出配方到 Excel 表格
+- **多角色权限** - 查看者 / 编辑者 / 高级编辑者 / 管理员
+- **Bug 追踪** - 内置问题反馈和追踪系统
+
+## 技术栈
+
+### 前端
+- **Vue 3** (Composition API + `<script setup>`)
+- **Vite** 构建工具
+- **Pinia** 状态管理
+- **Vue Router** 路由
+- **html2canvas** 配方卡片图片生成
+- **ExcelJS** Excel 导出
+
+### 后端
+- **FastAPI** (Python)
+- **SQLite** 数据库
+- **Uvicorn** ASGI 服务器
+
+### 部署
+- **Docker** 多阶段构建
+- **Kubernetes** (k3s)
+- **Traefik** 反向代理 + 自动 TLS
+
+## 快速开始
+
+### 前端开发
+
+```bash
+cd frontend
+npm install
+npm run dev
+```
+
+开发服务器启动在 `http://localhost:5173`，自动代理 `/api` 请求到后端。
+
+### 后端开发
+
+```bash
+pip install -r backend/requirements.txt
+uvicorn backend.main:app --reload --port 8000
+```
+
+### Docker 构建
+
+```bash
+docker build -t oil-calculator .
+docker run -p 8000:8000 -v oil-data:/data oil-calculator
+```
+
+访问 `http://localhost:8000`。
