   Palette

   Light is the base, defined on bare :root. The dark values live in one
   place — assets/css/_dark-tokens.css — and Hugo emits that single list into
   two selectors at build time (see layouts/_partials/head.html):

     :root[data-theme="dark"]                     an explicit choice
     @media (prefers-color-scheme: dark)
       :root:not([data-theme="light"])            the system default

   So the system preference is honoured by CSS alone. JavaScript is only
   needed to remember an explicit choice, and the page is correct without it.
