/* ═══════════════════════════════════════════════════════════════
   GRIDLY — E-Commerce Product Grid  (AAT-1)
   style.css — one shared stylesheet for all four pages.
   The whole point of this project is the PRODUCT GRID, so the
   catalogue is laid out with real CSS Grid:
     grid-template-columns: repeat(auto-fill, minmax(240px, 1fr))
   That single line gives a responsive multi-column layout with
   NO media queries — the columns re-flow to fit any screen.
