/* ============================================================
   TERRA3000 theme: the engineering-drawing sheet.
   Re-tuned from the taste "tech" direction. Every value is named
   after the site: asphalt, graphite, concrete, survey red.
   Load after foundation.css. Dark remap sits under @media screen
   so print always resolves the light sheet.
   Check: python3 /workspace/skills/taste/scripts/check_contrast.py src/css/theme.css
