/* ---------------------------------------------------------------------------
   Devnox Advisory — layout and components.
   Sections mirror the JSX files, in page order:
     primitives · nav · hero · stats · services · translation · process
     · modes · cases · logos · about · cta · footer

   Breakpoints, chosen from measured content needs rather than round numbers:
     1120px — the four-up service grid stops fitting
      900px — two-column layouts stack; the nav becomes a drawer
      640px — single column throughout

   Most sections don't need a media query of their own: they read --gutter and
   --section-pad-y from tokens.css, which are redefined per breakpoint there.
