Hello I would like to add prefers-color-scheme: dark media query to the default CSS generated when using this command pandoc -s -o f.html f.md, something like this:

@media (prefers-color-scheme: dark) {
  html {
    background-color: #1E1F21;
    color: #EEEFF1;
  }
  a {
    color: #EEEFF1;
  }
  a:visited {
    color: #EEEFF1;
  }
  blockquote p: {
    color: #606060;
  }
  hr {
    background-color: #EEEFF1;
  }
}

My rationale behind this enhancement is to make it easier to read the rendered HTML at night by default.
