/* ============================================================================
   CarbonCore — Alternate edition ("polished")
   ============================================================================

   Loaded AFTER site.css and overrides it. Deliberately a separate layer, not an
   edit of site.css: site.css is generated by the supplier's tools/build_css.py,
   so any change there would be lost on their next build and would make the two
   editions impossible to compare. Everything here is presentation only — no
   content, no wording, no structure is changed, so the two editions can be
   judged on look alone.

   Delete this one file and the link tags, and the site is byte-identical to the
   delivered version again.
