+### 额度策略开始按真实用量给出套餐建议
+
+- `租户额度与审计` 和 `额度` 工作区现在会根据当前项目最近的预算消耗、视频动作量、文案动作量和存储使用，直接给出 `试用 / 增长 / 规模 / 自定义` 的套餐建议。
+- `编辑租户额度` 弹层里的套餐预览也开始带上这层建议，不再只是静态展示当前选择的套餐说明；切换预设或继续调整自定义额度时，建议会跟着实时刷新。
+- 这让额度页从“只展示当前配额”继续往“告诉你现在更适合哪档套餐”收了一层，也把预算、动作池和真实使用节奏更明确地连在一起。
+
 ### 创作表单开始跟随来源任务动态刷新推荐值
 
 - `生成文案 / 创建 AI 视频 / 创建实拍剪辑 / 写复盘` 这四类创作表单，现在不只会在打开时算一次默认值；如果你在表单里切换来源任务，平台、标题、受众、画幅、时长、目标这些推荐值会继续跟着刷新。
