release: 发布墨呈 v0.6.0

新增能力：实现可编辑 DOCX 导出、通用主题样式翻译、Markdown 基础工具栏、统一导出菜单与导出进度提示；14 套主题支持纸张、页边距、字体、段落、代码、图片、图表、封面、页眉页脚和页码映射。问题修复：修复精确预览放大后的右侧留白、保存与导出默认路径、Desktop DOCX 媒体捕获超时、品牌改名后的安装目录迁移，并统一主题展示名称。兼容与部署：产品更名为墨呈/MorphDoc，保留 NSIS 安装身份；Desktop 内置 Pandoc 3.9.0.2，字体包支持安装向导可选与独立分发；Docker 内置 Chromium、Pandoc 和正式字体，支持离线部署。发布规则：新增 release/v<version> 唯一产物目录、Docker 镜像 tar.gz、Web 部署 ZIP、manifest.json 和 SHA256SUMS.txt；正式字体迁入版本化仓库目录并由 Git LFS 管理。验证结果：全项目测试、类型检查、生产构建、git diff --check、14 主题 DOCX 与视觉矩阵、Web API、Desktop 安装版、Word/WPS 可编辑性和字体门禁全部通过；离线镜像经 docker load 复验且容器保持 healthy。发布产物：Desktop 安装器与 ZIP、字体安装器与 ZIP、Web 镜像压缩包、离线部署包、发行说明和校验清单已整理至本地 release/v0.6.0。Windows EXE 当前未进行 Authenticode 签名，仅按公司内部发布风险规则分发。

+桌面端开发：

-编辑区和分页预览使用双向比例滚动同步。在任意一侧滚动时，另一侧会跟随到相同的全文阅读进度，方便定位并修改较长文档。
-
-预览工具栏支持滑块和手动百分比输入。缩放比例只改变浏览器显示，不改变纸张尺寸、分页结果或最终 PDF，并会单独保存在浏览器中。

-## Mermaid 配置与样式
-
-导出设置可以统一控制整篇文档的 Mermaid 布局、主题、外观和字体：
-
- 布局：Dagre、ELK；
- 主题：Mermaid 11.16.0 提供的 Default、Base、Dark、Forest、Neutral、Neo 和 Redux 系列；
- 外观：Classic、Hand-drawn、Neo；
- 字体：任意本地 CSS 字体族。
-
-未设置时使用 `dagre + default + classic`。单个 Mermaid 区块的 `config` Front Matter 优先于全局导出设置：
-
-````markdown
-```mermaid

-config:
-  layout: elk
-  theme: base
-  look: handDrawn
-  fontFamily: Microsoft YaHei

-  class B important
+```powershell
+npm run desktop:dev
 ```
-````

-`style`、`classDef`、`linkStyle`、`themeVariables` 和图表专属配置均由 Mermaid 官方渲染器处理。原始 `themeCSS`、`securityLevel` 和资源限制属于安全配置，不能由 Markdown 代码块覆盖。
+桌面端目录包和 Windows 安装包：

-ELK 使用官方 `@mermaid-js/layout-elk`，只有图表实际请求 ELK 时才加载核心布局代码。
-
-### Mermaid 长标签
-
-流程图节点标签的默认最大宽度为 320px，可以通过上例中的 `flowchart.wrappingWidth` 调整。
-
-需要自动换行时可以使用 Mermaid Markdown String：
-
-````markdown

-  A["`这是一段可以由 Mermaid 自动换行的较长节点文字`"]
+```powershell
+npm run desktop:package

+校验固定 Pandoc `3.9.0.2` 最小运行时，不能复用陈旧的
+`apps/web/dist`。产物位于 `apps/desktop/out/v0.6.0/`。

+## 文档与媒体

-## 本地导入 Typora 默认主题
+Markdown 支持 Front Matter、表格、任务列表、脚注、highlight.js、
+KaTeX、Mermaid 和安全的 ECharts YAML 围栏。

-项目不会打包或提交 Typora 官方默认主题。如本机已安装 Typora，可以将 GitHub、Pixyll 和 Whitey 三套适合打印的白色默认主题及 Typora 基础 CSS 复制到 Git 忽略的本地主题目录：
+独立一行的 `![标题](地址)` 会生成带标题的图片块。分页引擎将图片、
+Mermaid、ECharts 及其紧邻标题视为不可拆分媒体块，并按文档顺序串行
+计算。图片的缩放基准是原图先收缩到内容限宽后的高度；需要回填上一页时
+只缩放媒体内容，不缩放标题。这样可利用接近可容纳的页尾空白，同时避免
+跨页、重复重排和后续媒体顺序变化。
+
+ECharts 围栏语法、支持系列和安全边界详见
+[markdown-echarts 包文档](packages/markdown-echarts/README.md)。
+
+## 主题
+
+仓库内置 4 套 Typora 风格主题、4 套红头主题、3 套正式文档主题和
+3 套标书主题，默认使用 GitHub。主题由版本化
+`theme.json` 清单、主体 CSS、可选基础 CSS、打印 CSS 和资源组成。
+
+- 本地开发与 Compose：将主题目录放入 `.local/themes/`；
+- Desktop：从“更多 → 打开自定义主题目录”打开实际安装目录，再放入主题；
+- 主题格式、安全限制和资源引用详见[主题开发指南](docs/THEMES.md)。
+
+Compose 会把 `.local/themes` 只读挂载到容器。Typora 主题导入脚本只用于
+刷新本地开发副本：

 ```powershell
 npm run theme:import-typora
 ```

-默认从 Typora 安装目录的 `resources\style` 读取基础 CSS、主题和资源，写入 `.local\themes\typora-*`。启动开发服务后，这些主题会出现在预览页面的主题选择器中。
-
-导入工具不会默认覆盖已存在的目标。确认替换本地副本时使用：
-
-```powershell
-npm run theme:import-typora -- --replace
-```
-
-旧副本会移动到 `.local\theme-backups`。
-
-本地主题由动态主题注册器加载，CSS 中的相对字体和图片会通过受限资源接口提供。外部 URL、越界路径和符号链接逃逸会被拒绝。
-
-自定义主题目录、`theme.json`、CSS 组合顺序、资源引用和安全限制详见 [主题开发指南](docs/THEMES.md)。

+Fandol 字体采用 GNU GPL，并附带字体例外条款。完整许可证、上游说明、
+文件哈希和来源信息保存在该目录：

+- [`LICENSE.txt`](themes/_shared/official-fonts/LICENSE.txt)
+- [`README.md`](themes/_shared/official-fonts/README.md)
+- [`UPSTREAM-README.txt`](themes/_shared/official-fonts/UPSTREAM-README.txt)

+使用字体生成的 PDF、图片或 DOCX 不会仅因为使用该字体而自动受 GPL

+## npm、Electron 与 Chromium 组件
+
+项目直接或间接使用 MIT、Apache-2.0、BSD、ISC、EPL-2.0、MPL-2.0、
+CC-BY-4.0 等许可证的软件包。`package-lock.json` 固定具体依赖版本；
+Electron 和 Chromium 发行目录还包含其自身第三方许可证文件。
+
+构建产物不得删除 Electron、Chromium 或其他依赖已经附带的许可证文件。
+正式发布阶段应基于生产依赖和浏览器 Bundle 生成最终第三方清单，而不能
+仅以根目录项目许可证代替。
+
+## 仅限公司内部使用的 Typora 资源
+
+以下目录来自公司内部安装的 Typora 1.14.7，目前没有确认可用于公开再
+分发的完整授权：
+
+```text
+themes/typora-github/
+themes/typora-pixyll/
+themes/typora-whitey/
+```
+
+它们不受本项目内部专属许可证重新授权。即使其中部分样式可追溯到 MIT
+上游，也不能据此推定 Typora 修改版本整体可以公开分发。
+
+当前项目属于公司内部源码开放和内部部署阶段。根据现有内部使用决策，
+公司内部的源码仓库、Web/Docker 部署、Desktop 安装包、ZIP 和测试产物
+可以继续携带这三套主题，但不得向公司外部或公开网络发布、销售或授权。
+接收内部发行物的人员也不能依据根目录项目许可证对这三套主题进行公司外
+再分发。
+
+在将项目发布到公开 GitHub 仓库前，必须完成以下方案之一：
+
+1. 取得明确的公开分发授权；
+2. 使用许可证明确的上游资源重新实现并完成来源审查；
+3. 删除这些目录，并从准备公开的 Git 历史中清除其内容。
+
+仅在后续提交中删除目录仍会使旧版本存在于 Git 历史。若不能取得授权，
+公开发布应使用经过清理的历史或从合规快照创建新的公开仓库。上述门禁
+只针对公司外部和公开网络发行，不阻止当前公司内部源码共享、部署和
+安装包分发。

+# Desktop 桌面端
+
+`apps/desktop` 是 Electron 桌面应用。当前已经完成 Electron 壳、受限
+preload、进程内应用服务、原生 Markdown 打开与保存、同目录图片解析、
+本地主题目录、隐藏分页窗口、Electron Chromium PDF 输出和 Windows
+安装包。
+
+桌面端会记住上次窗口的位置、尺寸和最大化状态；窗口变化后延迟写入，
+异常退出后也能恢复。恢复时会按当前显示器工作区修正位置与尺寸，避免窗口
+落在屏幕外。Windows 安装包会注册 `.md` 和 `.markdown` 文件关联，
+双击文件或使用“打开方式”会在对应文档窗口中加载文件；同一文件只保留
+一个窗口，其他文件可以同时使用多个窗口。
+
+窗口每次获得焦点时会检查源文件是否被其他程序修改。检测到变化后提示
+重新加载，避免阅读或导出磁盘旧版本。
+
+“打开 Markdown”是顶部独立主操作；新建、保存、另存为、教程、主题示例
+和自定义主题目录统一收纳在“更多”分区菜单中。新建文档未保存时显示“未命名文档”，
+首次保存默认使用一级标题作为文件名；没有一级标题时使用首行文本，并会
+自动清理 Windows 非法文件名字符。“另存为”完成后当前窗口会追踪新文件，
+行为与常见办公软件一致。新文档无需先保存即可直接导出 PDF。
+
+## 开发
+
+从仓库根目录运行：
+
+```powershell
+npm run desktop:dev
+```
+
+桌面端不启动 Fastify，也不占用本地 HTTP 端口。React 界面通过受限 IPC
+调用 `packages/application` 中的 Markdown 渲染和主题服务，PDF 由
+Electron 自带 Chromium 生成。Web 与 Docker 继续通过 Fastify HTTP
+适配器使用同一套应用服务。
+
+## 构建与打包
+
+```powershell
+npm run build -w @md-to-pdf/desktop
+npm run desktop:package
+npm run make -w @md-to-pdf/desktop
+```
+
+`package` 和 `make` 会先调用根级 `build:web-runtime`，完整重建
+Markdown ECharts、Core、Renderer、Application、Preview Engine 和 Web，
+再按固定清单下载或复用 Pandoc `3.9.0.2` 缓存、校验官方 ZIP 的
+SHA-256，并执行版本与最小 DOCX 冒烟，最后才调用 electron-builder。
+不得绕过该链路直接调用 electron-builder。
+
+Pandoc 构建缓存位于被 Git 忽略的 `apps/desktop/.runtime/`。发行目录只
+包含 `pandoc.exe`、`COPYING.rtf`、`COPYRIGHT.txt` 和生成的审计清单，
+不会携带官方 MSI、手册、下载缓存或用户级 Pandoc 配置。已准备运行时可用
+以下命令离线复验：
+
+```powershell
+npm run verify:pandoc-runtime -w @md-to-pdf/desktop
+```
+
+版本化目录包、NSIS `Setup.exe` 和 ZIP 输出到
+`apps/desktop/out/v0.6.0/`。该目录被 Git 忽略。公司内部分发以
+`MorphDoc-0.6.0-x86_64-Setup.exe` 为正式安装包，ZIP 作为免安装
+辅助包；当前未配置代码签名，Windows 首次运行可能显示“未知发布者”
+提示。
+
+NSIS 使用标准辅助安装模式，支持选择当前用户/所有用户安装和自定义安装
+目录，并创建桌面及开始菜单快捷方式。正式安装包作为 Gitea Release 附件
+发布，不提交进 Git 历史。
+
+桌面和开始菜单快捷方式由 `build/installer.nsh` 显式创建，安装完成后的
+“运行”操作直接启动 `MorphDoc.exe`，不依赖快捷方式文件。
+
+界面、快捷方式与卸载项使用中文名“墨呈”，窗口标题为
+“墨呈 · MorphDoc”，默认安装目录和 Windows 主程序分别为 `MorphDoc`
+和 `MorphDoc.exe`。NSIS appId 保持 `com.md-to-pdf.desktop`，确保
+v0.5.1 覆盖升级沿用原卸载身份；v0.6.0 使用独立的安装位置注册表键，
+升级时由旧版卸载器清理 `md-to-pdf` 目录，再安装到 `MorphDoc` 目录，
+避免产品改名后继续继承旧目录名。
+
+当前目录包只包含一套 Electron Chromium，不携带 Playwright Chromium；
+Pandoc 作为未修改的独立程序随 Desktop 内置，通过受控子进程执行。
+Web 静态资源作为只读资源放在 Electron `resources/dist` 下，生产环境通过
+`mdpdf://bundle/` 自定义协议加载。
+
+## 链接与窗口行为
+
+- 当前文档 `#anchor` 在当前预览中定位；
+- HTTP/HTTPS 链接交给系统默认浏览器；
+- `mailto:` 等系统协议交给操作系统处理；
+- 上级相对路径、本地绝对路径和 `file:` URI 均可尝试通过系统打开；
+- Markdown 文件会提示在当前窗口或新窗口打开；
+- 同一规范化文件路径只允许一个窗口，重复打开时聚焦已有窗口；
+- 本地目标不存在时显示明确错误，不允许链接替换预览 iframe。
+
+发行包只保留 Electron 的简体中文和英文语言包，其他 Chromium 运行时
+组件保持完整，以兼顾安装体积和不同 Windows 图形环境下的运行可靠性。
+
+## 安全边界
+
+- 应用窗口和 PDF 窗口均关闭 Node Integration；
+- 启用 Context Isolation 和 Chromium Sandbox；
+- preload 只暴露打开 Markdown、渲染、主题、生成 PDF 和保存 PDF 所需
+  的窄接口；
+- 本地图片只能从当前 Markdown 所在目录内读取，并拒绝路径穿越和符号
+  链接越界；
+- 主进程校验 IPC 发送者和分页载荷；
+- PDF 窗口使用独立内存 Session，并阻止外部网络资源；
+- 应用页面使用自定义协议，不使用 `file://`。

+# Markdown PDF 媒体分页示例
+
+这份文档集中展示常用排版、不同尺寸图片、Mermaid 与 ECharts 的渲染和分页效果。
+
+## 基础排版
+
+- [x] Markdown 实时预览
+- [x] 图片、Mermaid 与 ECharts
+- [x] 快速预览和精确 PDF 预览
+- [ ] 根据实际文档继续扩展主题
+
+| 能力 | 示例用途 |
+| --- | --- |
+| 表格与任务列表 | 验证主题基础样式 |
+| 数学公式 | 验证字体和基线 |
+| 媒体块 | 验证限宽、缩放与分页 |
+
+行内公式：$E = mc^2$。
+
+> 预览与 PDF 共用相同的渲染结果、主题 CSS 和分页结构。
+
+## 网络图片
+
+下面只保留一张网络图片，用于验证远程资源获取与离线失败提示。

+
+## Base64 图片块
+
+### 横向图片：限宽基准
+
+1600 × 900 的横图会先按正文宽度等比例收缩，收缩后的高度才是分页算法使用的基准高度。
+
+![Base64 横向图片 1600×900][base64-wide]
+
+### 边界图片：上一页空白回填
+
+这一段用于形成稳定的分页边界。分页算法会保留标题、图注和间距的原始尺寸，只计算图片主体还能使用的高度。如果主体只需轻微缩小，并且缩放率仍在允许范围内，就尝试回填到上一页空白区域。
+
+为了覆盖长文档场景，这里继续补充少量正文，使媒体块靠近默认 A4 页面底部。媒体元素必须按照源文档顺序串行处理，前一个媒体完成重排以后，后一个媒体才基于新的版面重新计算。
+
+![Base64 边界图片 1200×880][base64-boundary]
+
+### 纵向图片：单页高度适配
+
+900 × 1800 的纵图在限宽后仍可能超过单页内容区，此时应继续等比例缩小并完整放在一页内。
