/* ==========================================================================
   layout.css — Section-level structure for every page region
   ─────────────────────────────────────────────────────────────────────────
   Rules here control the skeleton of each section: widths, vertical rhythm,
   grid/flex containers, and responsive breakpoints.
   Component-level detail (colours, typography, specific elements) lives in
   components.css. Keep layout rules structural — avoid visual opinions here.

   Mobile-first: base styles target small screens; min-width media queries
   layer on top for tablet and desktop. No separate responsive.css needed.
