在我的文档中，我重新定义了命令\thefigure以根据需要自定义标题。我还使用了四种不同的 mdframed 环境：一种用于证明，一种用于示例，一种用于命题，一种用于定义。事实证明，我使用这些环境不仅定义特定类型的框架和背景颜色；还定义这些框架内的字体。因此，证明采用脚注大小；而示例采用小斜体字体（定义和命题具有标准傅立叶字体）。
问题如下。我的文档有几个图，其中一些属于这些不同的 mdframed 环境。当在这些 mdframed 环境中包含图时，标题样式显然保持正常。也就是说，如果在证明环境中有一个图，则标题将不会采用脚注大小（类似地；如果在示例中，图的标题将不会采用小斜体字体）。正如您所猜测的，我希望我的标题能够获得它们所在的相应 mdframed 环境的字体样式。也就是说，我希望证明环境中的标题采用脚注大小，示例环境中的标题采用斜体和小字体。但是，我不希望更改标题的编号。也就是说：标题样式应适应相应的 mdframed 环境字体样式；但标题的编号不应改变。这是一个 MWE，展示了我如何定义 mdframed 环境以及标题。为了通用性，MWE 并没有达到应有的最小化；但我认为这样更好。

下面您可以看到一个证明，其中的标题样式并未进行相应的调整。
有人能帮我实现所需的输出吗？也就是说，我应该怎么做才能获得固定编号但又适合标题的样式？谢谢大家的时间。:)

与原始代码相比，唯一的区别在于包含了\captionsetup{font=footnotesize}。\newtheoremstyle{mystyle0}...输出如下所示。
