 * Colour mode (default) paints the page background from the current hour's sky at the chosen
 * place: html[data-sky] picks the gradient, html[data-night="1"] switches to the deep palette.
 * Until the forecast arrives there is no data-sky, so the neutral daytime look below applies.
 * Dark mode (html[data-mode="dark"]) is plain black; JS removes the sky attributes then.
