流程
输入文章
AI 自动生成 PPT 结构
自动生成分镜描述
自动推送到 Gamma / SlidesAI / 飞书文档
特点与能力：
输入：文章 / 长文（Notion / 粘贴 / Google Sheet）
AI：自动拆分成幻灯片大纲（标题 + 3 要点/页）
可选：为每页生成配图 Prompt 并调用图像 API 批量生成图片（OpenAI Image / Midjourney 占位）
自动调用 PPT 生成服务（占位 API；你也可以替换为 SlidesAI、Google Slides API、自建 PPT 服务）把每页合成成 PPT 文件（含图片）
上传到 Google Drive（或 OSS）并回写 Notion（归档）
错误重试、并发控制与导出链接回应
提醒：导入后请替换所有 YOUR_... / 占位 API URL / 凭证（OpenAI Key、Google Drive、Notion 等）。

⚙️ 使用与注意事项（必读）
替换凭证：把 OPENAI_CRED_ID、NOTION_CRED_ID、YOUR_NOTION_PPT_DB_ID、以及所有 api.example.com / api.your-oss.com 占位替换成你自己的服务或供应商。
PPT 生成 API：示例用了 https://api.example.com/generate-ppt 作为占位。你可以替换成：
使用第三方 PPT 服务（SlidesAI、DeckRobot 等）
使用 Google Slides API（需额外实现 slides 组装逻辑）
自建微服务（接收 JSON，返回 PPT）
图片生成：如果你不想为每张幻灯片生成图片，可删除 Image 节点并在 Create PPT 时只传文字内容。
并发与配额：生成大量图片或调用 OpenAI 会消耗配额，请先测试少量幻灯片（1–3 页）确认效果与成本。
调试流程：导入后逐节点 Execute Node 调试，检查 OpenAI 输出是否为 JSON（Parse Slides JSON 节点有简单的容错解析）。
扩展：我可以把 Create PPT 节点替换为 Google Slides 的完整实现，或把图片生成替换为 Midjourney / Stability / DALL·E 池化调用（批量队列模式）。
