/* ============================================================
   articles.css
   ------------------------------------------------------------
   Article body styling only. The header, navigation, sidebar and
   footer come from the shared shell in /inc/, so this file is
   what styleblog.css used to be minus everything the shell now
   provides.

   Every colour is a theme token. The old file hardcoded #ca8d1c
   borders and #f0e6d2 panels, which is why articles stayed on a
   parchment ground while the rest of the site moved to the night
   sky.
