/* =============================================================================
   ATLAS — Corporate / Professional Services PHP theme
   assets/css/app.css

   A "printed report" design language: warm paper ground, near-black ink, one
   deep evergreen accent, hairline rules, numbered section labels, a single
   typeface (Inter) with a tight weight hierarchy, and mostly-square geometry.
   Deliberately different from any blue-SaaS look.
