+"""模板编辑器 API — 剪辑计划收敛为模板编辑器内部概念.
+
+挂载路径: /api/v1/templates/{template_id}/editor/
+
+核心设计:
+- 每个模板有且仅有一个"草稿"剪辑计划 (config.is_template_draft=True)
+- 首次访问自动创建草稿
+- 内部复用 EditPlanService 的业务逻辑，不重复实现
+- 原 /edit-plans/ 路由继续保留作为兼容层
+
+当前已实现端点（Phase 2 第一步）:
+- GET    /              获取编辑器草稿详情
+- PUT    /              更新草稿基本信息
+- POST   /publish       发布草稿到模板（草稿→正式模板）
+- GET    /clips         获取草稿片段列表
+- POST   /clips         创建片段
+- PUT    /clips/{id}    更新片段
+- DELETE /clips/{id}    删除片段
+
+后续子路由（BGM/转场/滤镜/AI/导出等）将逐步迁移。
