我在阿拉伯语文档中使用 tcolorbox 来处理定理示例的多语种，等等。我将环境标题放在 tikz 框中，放在页边距中（在右边距中，阿拉伯语以从右到左的模式书写）我希望（基本上是针对“小”示例，但也适用于其他示例...）获得框和节点的良好对齐。假设一个框和一个高度相同的节点。我手动完成，因为我不明白 tcolorbox 如何决定将节点准确放在哪里...我给出了一个 ECM。

及其使用 xelatex 的编译
我希望标题节点矩形与北边界线（黄色）完全重叠。在示例 1a 中可以看到，框太小，我想将其也安排在底部，以便南边界线与标题框完全重叠。我在示例 1b 中手动安排它，在框的文本中使用命令 \vspace*{.57cm}。我希望自动执行此操作，即获得具有相同高度的框和节点。我该怎么做？
同样，我希望获得标题节点矩形和标题框的良好对齐。非常感谢
