`<meta name="color-scheme" content="light dark" />` is a hint to the browsers
that the page can be rendered in light as well as in dark mode
and that the browser can apply corresponding defaults.
as we do not add css colors on our own,
this is sufficient for letting generated html messasge being rendered
in dark mode.
