/* ---- RESPONSIVE ----
   C-110 full-site audit: the vn-drive mockup was authored desktop-only, so the
   home/about chrome grids (qbar, trust, why, testimonials, blog teasers,
   banners, category tiles, product grid) had NO collapse below their desktop
   column count. On a 375px phone those 3–4–6-col grids cram each cell to
   ~80–100px → labels wrap one word per line and product cards clip their price.
   This block steps every house grid down through tablet → phone so each cell
   has a sane minimum width. Single source of truth for chrome responsiveness. */
