/* ============================================================
   DATA CYNICAL — Responsive Stylesheet  v3.0
   ============================================================
   Single source of truth for ALL breakpoints.
   Load order: styles.css → responsive.css → page <style>

   STRATEGY:
   • Override CSS variables at each breakpoint — all consuming
     elements automatically scale without extra rules needed.
   • Add element-specific layout rules only when variables
     aren't enough (e.g. grid column changes, nav hamburger).

   Breakpoints:
   1400px  Container maxes out — no more scaling needed above
   1200px  Laptop
    992px  Tablet landscape
    768px  Tablet portrait — hamburger nav
    600px  Large mobile
    375px  Small phones
