   Dark palette. The design system defines none — everything below is authored
   to match its spirit (ink/paper roles invert, the spine accent lightens for
   contrast, the five pastel tints darken so they don't glow). It is declared
   three times on purpose: once for the OS preference, once for the explicit
   toggle, and once restating the LIGHT values under an explicit "light" flag.
   Skipping that third block is exactly how a past version of this site left
   near-white headings on cream paper for anyone who chose light on a
   dark-mode machine — every value a dark block touches has to be un-touched
   somewhere just as explicitly.
