更改标题框左右两侧的Tcolorbox标题规则颜色和粗细

Question

我想让我的 tcolorbox 有两种不同的风格标题如图所示：

这些是用My Title Style Default和编码的My Title Style Special，但使用整个tcolorbox（而不仅仅是标题）。特别的风格有三个明显的变化：

1. 标题四边的规则颜色都会改变。正文其他三边（西、南、东）的规则不应改变。
2. 左右规则较粗，以突出差异。
3. 一些字符xxx是按照左手法则放置的。

到目前为止，我只能获得要求 2 的一部分，并绘制规则的底部部分特别的盒子：

My Style Default这些在和中编码My Style Special。

问题：

• 主要的：我应该对 做哪些修改才能My Style Special获得 所需的标题样式tcolorbox。三项要求中，2 和 3 更重要，因此愿意接受并回答，无需 1。

• 奖金：有没有更好的方法来放置文本xxx？我不得不手动调整坐标

代码：

不完全是您想要的，但类似。
