/* ATH/N — one stylesheet for the whole site.
   Light by default with a matching dark theme (html[data-theme="dark"]). White and near-white
   planes, one neutral grey scale, system type with tight display tracking, frosted glass for
   chrome, pill buttons. Colour appears only as small accents: the link blue, the brand's
   electric blue (the slash, status lights, progress), and status colours.
