Where is the dark theme located?

The demo on the playground page displays the preview with a dark theme, and I was wondering where that might be located so I can use it in my own instance.

同样求问。

目前只发现可通过下面语句覆盖样式，不太方便。

:deep(.markdown-body) {
  background-color: #fff !important;
  color: #000 !important;
}

I used :deep(.bytemd) and :deep(.markdown-body) to override style.
