/* ============================================
   Responsive Breakpoints — CSoft Healthcare (responsive.css)
   ============================================
   Loaded after style.css. Overrides layout at three widths:

   @1024px — Tablet landscape: 2-col grids, stacked hero, compact nav
   @768px  — Tablet portrait: single-col cards, smaller type, tighter sections
   @480px  — Mobile: hamburger nav visible, full-width buttons, blog banner tweaks

   Breakpoint strategy: desktop-first (max-width queries).
   Pair with main.js mobile-nav toggle (.hamburger / .mobile-nav.active).
