路由到场景后 → 加载该场景的 README.md 获取详细参数和用法 → 按下方执行流程操作。
📋 通用执行流程（所有场景共用）
第一步：分析需求
- 明确要生什么（主题、内容要点）
- 确定场景类型（已由路由判断）
- 确定数量（几张图）
- 确定比例（16:9 / 3:4 / 1:1 等）
第二步：规划方案（多图场景必须）
单图：可跳过直接生成。 多图场景（长图/幻灯片/漫画/小红书/文章插图）：必须先输出规划，等用户确认后再执行。
规划输出格式：
| 序号 | 内容概要 | 类型/布局 |
|-----|---------|----------|
| 1 | xxx | xxx |
| 2 | xxx | xxx |
**场景**：xx | **风格**：xx | **比例**：xx | **预计**：N张
第三步：执行生成
| 场景 | 执行方式 | 规则 |
|---|---|---|
| 📊 信息图 | 场景脚本直接调用 | 单张可并发 |
| 🖼️ 封面图 | 场景脚本直接调用 | 单张 |
| 📜 长图 | core引擎串行 | 铁律：必须串行！ 首屏text_to_image，后续image_to_image参考上一屏，最后merge拼接 |
| 📑 幻灯片 | 场景脚本逐页 | 串行逐页生成 |
| 📖 漫画 | 场景脚本逐页 | 串行！ 首页text_to_image定调，后续image_to_image参考上一页 |
| ✏️ 文章插图 | 场景脚本批量 | 各章节独立，可并发（≤8张） |
| 📱 小红书 | 场景脚本逐张 | 串行！ 首张定调，后续参考上一张保风格一致 |
| 🛍️ 营销物料 | core引擎+模板 | 同风格可并发（≤8张） |
| 🔄 图生图 | core直接调用 | 单张 |
| 🎨 单图 | core直接调用 | 单张 |
第四步：质量校验
- 生成完成后，含中文文字的图用
core/image_to_text.py -m ocr校验文字是否清晰 - OCR结果与预期不符 → 用
core/image_to_image.py迭代修复（参考guides/text-rendering.md） - 多图场景完成后，逐张展示给用户确认，不满意的单张重新生成
