   Three themes. The light palette is defined on bare :root, and the dark one
   is redefined twice: once behind prefers-color-scheme for the default
   "system" setting, once behind [data-theme="dark"] so an explicit choice
   wins in both directions. No colour is ever defined only inside a media
   query, so nothing can end up unstyled.
