/* amenbo — dark-first design tokens.

   AI = blue, humans = coral. No third accent (purple retired) so the bright
   logo never reads as a different world from the site. crofty's warm-earth /
   serif defaults are intentionally replaced; `crofty doctor` still confirms
   the output contract (canonical link, feed, no third-party tracking). */
