   regardless of the visitor's OS color-scheme preference. The editorial /

   pinned to their light values here rather than left to auto-invert via
   tokens.css's own `prefers-color-scheme: dark` block. This also avoids
   text/background combinations that were only verified for the light
   palette (e.g. navy-on-cream) silently becoming navy-on-navy. */
