+# 项目概览（yys-editor）
+
+目标与定位
+- yys-editor 是一个基于浏览器的可视化编辑器，用于拖拽排布素材并生成展示效果（围绕式神/御魂等要素）。
+- 适合快速制作、调整与导出展示图（如阵容/排行等）。
+
+技术要点
+- Vue 3 + Vite + Element Plus + Pinia + vue-i18n
+- 入口：`index.html` -> `/src/main.js` -> `App.vue`
+- 路径别名：`@` -> `src/`
+- 资源：大量静态图片位于 `public/assets/`
+- 语言：中文、日文（从浏览器语言推断，fallback 为 `zh`）
+
+当前现状
+- 包管理器：npm（存在 `package-lock.json`）
+- 脚本：`dev`/`build`/`preview`/`lint`/`format`
+- Lint/Format：ESLint + Prettier（无项目级 Prettier 配置文件，使用默认）
+- 测试：未配置自动化测试
+
+典型编辑流程
+1) `npm install`
+2) `npm run dev` 在 http://localhost:5173/ 进行开发与手动验收
+3) `npm run lint` + `npm run format` 保持风格统一
+4) `npm run build` 产出 `dist/`，`npm run preview` 进行生产包预览
+
+其它
+- 状态存储使用 Pinia，并通过 `localStorage` 自动保存；应用启动时支持恢复上次未保存内容。

+# yys-editor 项目结构（概要）
+
+根目录
+- `index.html`：Vite 入口 HTML，挂载点 `#app`，引入 `/src/main.js`。
+- `package.json` / `package-lock.json`：npm 包与脚本；包管理器为 npm。
+- `vite.config.js`：Vite 配置，`@` -> `src/`。
+- `jsconfig.json`：编辑器路径提示（`@/*` -> `./src/*`）。
+- `.gitignore`：忽略 `node_modules/`、`dist/` 等。
+- `.vscode/`：推荐扩展（Volar）。
+- `README.md`：项目说明（中文）。
+- `public/`：静态资源目录（大量图片素材：`assets/Shikigami`, `assets/Yuhun` 等）。
+
+`src/`
+- `main.js`：应用入口，注册 Element Plus、Icons、vue-i18n、Pinia、vue3-draggable-resizable；挂载 `App.vue`。
+- `App.vue`：主布局（工具栏、侧边栏、工作区 Tab），根据文件类型切换主要编辑视图。
+- `components/`：
+  - 核心：`Yys.vue`, `YysRank.vue`, `Toolbar.vue`, `ProjectExplorer.vue` 等
+  - 基础：`ShikigamiSelect.vue`, `YuhunSelect.vue`, `Watermark.vue`, `HelloWorld.vue` 等
+  - `components/icons/`：若干图标组件
+- `assets/`：基础样式 `base.css`, `main.css` 与 logo 等
+- `data/`：若干 JSON 数据（如 `Shikigami.json`, `Yuhun.json`, `property.json`, `updateLog.json`）
+- `locales/`：多语言资源 `zh.json` 与 `ja.json`
+- `ts/`：脚本与 store
+  - `files.ts`：Pinia store（文件页签、可见性、删除/重命名；含 `localStorage` 自动保存与启动恢复提示）
+  - `useGlobalMessage.ts`：全局消息（Element Plus）
+- `types/`：类型定义（如后续扩展）
+
+说明
+- 未见 `router` 相关文件；当前为单页多区域布局。
+- 构建产物输出到 `dist/`（`npm run build`）。

+# yys-editor 技术栈与风格约定
+
+技术栈
+- 前端框架：Vue 3（Composition API，部分 SFC 使用 `<script setup lang="ts">`）
+- 构建与开发：Vite
+- UI 组件：Element Plus（含 `@element-plus/icons-vue`）
+- 状态管理：Pinia（示例：`src/ts/files.ts` 存储文件页签等，含本地存储自动保存）
+- 国际化：vue-i18n（`src/locales/zh.json` + `src/locales/ja.json`，默认从浏览器语言推断，fallback 为 `zh`）
+- 拖拽缩放：vue3-draggable-resizable
+- 其它依赖：`@vueup/vue-quill`（如后续使用富文本）/ `html2canvas` / `vuedraggable` 等
+
+工程与路径
+- 别名：`@` 指向 `src/`（见 `vite.config.js` 与 `jsconfig.json`）。
+- 入口：`index.html` -> `/src/main.js` -> `App.vue`。
+- 静态资源：`public/`（大量图片素材位于 `public/assets/...`）。
+
+代码风格
+- 代码格式：Prettier（未见项目级配置，使用默认规则；脚本仅格式化 `src/`）。
+- 语法检查：ESLint（`eslint-plugin-vue` + `@vue/eslint-config-prettier`；脚本已启用 `--fix`）。
+- 组件命名：PascalCase 单文件组件（`.vue`），按功能归档于 `src/components/`。
+- 类型：以 JS 为主，SFC 中可使用 TS（经 Vite/ESBuild 处理，无专门 `tsconfig.json`，有 `jsconfig.json` 路径提示）。
+- 国际化：新增/修改文案时，请同步维护 `zh.json` 与 `ja.json`，避免硬编码 UI 文案。
+- 状态与持久化：Pinia store 通过 `localStorage` 自动保存，注意 key 兼容；涉及 schema 变更时考虑迁移逻辑。
+
+样式
+- 常规样式位于 `src/assets/*.css`，组件中常用 `<style scoped>` 以局部隔离。
+- UI 主题由 Element Plus 提供，如需自定义主题请统一约定变量来源。
+
+提交与约定
+- 未发现提交规范配置（如 commitlint/husky），建议信息清晰、原子化提交。必要时中英文均可，但保持一致性。
+
+测试
+- 未配置自动化测试框架；变更请重点进行手动验收（参见 `task_completion_checklist.md`）。

+## Documentation Lookup
+
+When documentation lookup is required:
+- The agent should use Context7 as the primary source of truth.
+- Do not rely on assumptions if documentation can be retrieved via Context7.
+
+## Progress Update Rules
+
+The project progress is tracked in:
+- `/docs/1management/plan.md`
+
+When the user explicitly states that a task or step is completed (e.g. “当前任务完成”, “这一步做完了”, “可以更新进度了”):
+
+The agent MUST:
+1. Identify the corresponding step or module in `plan.md`.
+2. Update the completion status or percentage of that specific step.
+3. Recalculate and update the overall progress to reflect this change.
+4. Keep all other progress entries unchanged.
+
+The agent MUST NOT:
+- Update progress proactively without explicit confirmation from the user.
+- Guess completion status or infer progress implicitly.
+- Modify unrelated sections in `plan.md`.
+
+If the mapping between the completed task and `plan.md` is ambiguous:
+- Ask for clarification before making any changes.
