   AtlasOA Trust Center stylesheet
   ------------------------------------------------------------
   What: shared styles for every page under /trust/.
   Why: one stylesheet keeps all Trust Center pages identical
   and lets enterprise-refresh.css (loaded after this file)
   apply the site-wide light/dark theme. Colors come from the
   --eo-* tokens that enterprise-refresh.css defines for both
   themes, so nothing here needs its own dark-mode block.
   Base nav/header/card rules mirror resources.html so the
   override layer recognizes and restyles them the same way.
