* - lib/index.js 服务端 ESM（cordis 插件，健康路由）
|
||||
* - lib/client.js 客户端单文件 CJS（window.__ModuleLoader__.load 握手；
|
||||
* react / @deepseek-ai/* 由宿主模块系统提供，保持 external）
|
||||
* esbuild 优先用本包 node_modules 的平台二进制，其次复用相邻项目 vendor。
|
||||
* esbuild 走 JS API；pdf.js worker 源码以字符串注入客户端 banner，
|
||||
* 运行时用 Blob URL 起 module worker（不依赖服务端路由，F5 即生效）。

## 补记（PDF 自绘阅读器：抓手/空格拖拽/H 切换/缩放）
|
||||
|
||||
- 用户需求：PDF 阅读器加抓手工具——顶部 ✋ 按钮；按住空格期间鼠标变抓手、左键拖动平移、
|
||||
松开空格取消；快捷键 H 一键切换抓手；抓手态下拖动即可移动页面。
|
||||
- 关键决策：原生 Chrome PDF 视图（iframe）内部无法拦截鼠标 → 改用 pdf.js 自绘渲染
|
||||
（画布多页纵向 + 视口按需渲染 + DPR≤2）。
|
||||
- 实现：
|
||||
① PdfViewer 组件：工具栏 [✋抓手][−][百分比][＋][⤢适应宽度]；缩放 0.2~5；
|
||||
抓手三入口——空格按住（输入框不劫持、松开取消）/ H 常开切换 / 顶部按钮；
|
||||
抓手态 cursor grab/grabbing，pointer 捕获拖拽改 scrollLeft/Top；
|
||||
② worker 零服务端依赖：build.mjs 改 esbuild JS API，把 pdf.worker.min.mjs 源码以
|
||||
__WT_PDF_WORKER__ 字符串注入 client banner（bundle 2.6MB），运行时 Blob URL 起 module worker；
|
||||
失败自动回退原生 iframe（服务端 MIME 已补 application/pdf 备用）；
|
||||
③ 服务端 file 路由 MIME 补 pdf/markdown/log/bmp/ico。
|

- 验证（functional-diag STEP12 + 04_test/fixture.pdf 夹具）：canvasW=439 自绘渲染；
