            How to Apply These Terms to Your New Programs
  If you develop a new program, and you want it to be of the greatest
 possible use to the public, the best way to achieve this is to make it
 free software which everyone can redistribute and change under these terms.
  To do so, attach the following notices to the program.  It is safest
 to attach them to the start of each source file to most effectively
 state the exclusion of warranty; and each file should have at least
 the "copyright" line and a pointer to where the full notice is found.
    <one line to give the program's name and a brief idea of what it does.>
    Copyright (C) <year>  <name of author>
    This program is free software: you can redistribute it and/or modify
    it under the terms of the GNU Affero General Public License as published
    by the Free Software Foundation, either version 3 of the License, or
    (at your option) any later version.
    This program is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
    GNU Affero General Public License for more details.
    You should have received a copy of the GNU Affero General Public License
    along with this program.  If not, see <https://www.gnu.org/licenses/>.
 Also add information on how to contact you by electronic and paper mail.
  If your software can interact with users remotely through a computer
 network, you should also make sure that it provides a way for users to
 get its source.  For example, if your program is a web application, its
 interface could display a "Source" link that leads users to an archive
 of the code.  There are many ways you could offer source, and different
 solutions will be better for different programs; see section 13 for the
 specific requirements.
  You should also get your employer (if you work as a programmer) or school,
 if any, to sign a "copyright disclaimer" for the program, if necessary.
 For more information on this, and how to apply and follow the GNU AGPL, see
 <https://www.gnu.org/licenses/>.

 ## 輸出格式
 所有輸出一律打包為 `.tar` 檔案：
 ### PDFMathTranslate 輸出
 ```
 output.tar
 ├── original.pdf      # 原始 PDF
 └── translated-*.pdf  # 翻譯後的 PDF
 ```
 ### BabelDOC 輸出
 ```
 output.tar
 ├── translated-*.pdf  # 翻譯後的 PDF（如果選擇 pdf-*）
 ├── translated-*.md   # 翻譯後的 Markdown（如果選擇 md-*）
 └── translated-*.html # 翻譯後的 HTML（如果選擇 html-*）
 ```
 ---
 ## 環境變數設定
 ### 翻譯服務（PDFMathTranslate）
 > 💡 `PDFMATHTRANSLATE_SERVICE` 可選值：`google`（預設）、`bing`、`deepl`、`openai`、`azure`
 ```yaml
 environment:
  - PDFMATHTRANSLATE_SERVICE=google
 ```
 | 服務     | 說明             | 需要 API Key |
 | -------- | ---------------- | ------------ |
 | `google` | Google 翻譯      | ❌ 免費      |
 | `bing`   | Bing 翻譯        | ❌ 免費      |
 | `deepl`  | DeepL 翻譯       | ✅           |
 | `openai` | OpenAI API       | ✅           |
 | `azure`  | Azure Translator | ✅           |
 ### 使用付費服務
 如需使用付費服務，需設定對應的 API Key：
 ```yaml
 environment:
  - PDFMATHTRANSLATE_SERVICE=openai
  - OPENAI_API_KEY=sk-xxxxx
  # 或
  - PDFMATHTRANSLATE_SERVICE=deepl
  - DEEPL_API_KEY=xxxxx
 ```
 ---
 ## 適用場景
 ### PDFMathTranslate 適合
 - ✅ 學術論文翻譯
 - ✅ 數學/物理教科書
 - ✅ 包含 LaTeX 公式的文件
 - ✅ AI/ML 論文
 ### BabelDOC 適合
 - ✅ 一般文件翻譯
 - ✅ 需要 Markdown 輸出（方便後續編輯）
 - ✅ 需要 HTML 輸出（網頁展示）
 - ✅ 快速翻譯大量文件
 ### ⚠️ 共同限制
 - 掃描版 PDF（系統會自動偵測並使用 OCR 處理）
 - 複雜排版的雜誌
 - 手寫文件
 ---
 ## 如何選擇引擎？
 | 需求               | 推薦引擎         |
 | ------------------ | ---------------- |
 | 有數學公式         | PDFMathTranslate |
 | 需要 Markdown 輸出 | BabelDOC         |
 | 需要 HTML 輸出     | BabelDOC         |
 | 一般商業文件       | 兩者皆可         |
 | 追求翻譯品質       | PDFMathTranslate |
 | 追求翻譯速度       | BabelDOC         |
 ---
 ## 注意事項
 1. **模型已預載**：所需模型已在 Docker build 階段下載
 2. **不會隱式下載**：Runtime 不會下載額外模型
 3. **預設免費服務**：使用 Google/Bing 翻譯（免費）
 4. **離線模式**：可設定 `HF_HUB_OFFLINE=1` 確保完全離線
