/* =================================================================
   Mobile responsiveness overhaul — 2026-07-11

   Three breakpoints:
     - 1024px : small tablet / large phone landscape — multi-col grids
       collapse to 2 cols; nav switches to hamburger.
     - 720px  : typical phone portrait — most grids collapse to 1 col;
       typography clamps; sticky CTA on detail pages.
     - 480px  : small phone — extra padding reductions; stacked
       email inputs; tighter h1 size.

   Rules:
     - Tap targets >= 44px tall.
     - Inputs >= 16px to avoid iOS auto-zoom.
     - No fixed widths > 100vw — overflow-x is hidden globally below 720px.
     - Tables are wrapped in .table-scroll (added to templates) for
       horizontal scroll on phones.
