Proposal

<meta name=color-scheme content="light dark">

https://developer.mozilla.org/en-US/docs/Web/CSS/color-scheme

Motivation and context

(Apologies in advance, if the CSS files already implement that feature.)

I just got here and read the index.html. I noticed it doesn't have native support for "automatic dark-theme", which is fundamental for accessibility purposes. On OLED/microLED displays, it has the side-effect of saving energy (if the user wants it)

Thanks for the suggestion. We can mention the color-scheme meta tag in the docs but I don't think we would include it in the HTML template by default. It's best for web developers to make the conscious decision wether to support dark mode or not.

I would like to see it documented. That would be nice.
