/* =====================================================================================
   Athena layout contract

   This is intentionally the last stylesheet. Feature styles own their visual language;
   this file owns the geometry shared by every feature: page gutters, header/action
   alignment, intrinsic-width containment, responsive toolbars, and local table scrolling.
   Keeping those rules here prevents a new dashboard from reintroducing page-level
   horizontal scrolling or a one-off spacing system.
