/* Whole-site stylesheet.
 *
 * Browser default font, browser default colours, browser default everything.
 *
 * color-scheme: light dark is the entire theme handling. The browser paints
 * its own light and dark canvas, text, link and form-control colours, so dark
 * mode is plain inversion. There is deliberately no dark-mode rule anywhere
 * in this file: any such rule is something the browser did not ask for.
 *
 * The only layout is one centred column, which is also the whole of the
 * mobile layout, and images that do not overflow it.
