   Follows the visitor's system setting. The dark palette is a warm
   charcoal, not near-black: the first version was #13120e and read as a
   black hole rather than a dark theme. Every token is declared in the
   bare :root first, so the un-stamped default state is always complete.
   Paper and ink carried over from the extension popup. One accent:
   #ff0033, lifted straight out of the logo, spent on the mark and on the
   surfaces the extension replaces. Nothing else is allowed to be red.
