   DNP RESPONSIVE LAYER
   Loaded LAST on every storefront page (after style.css and
   ecommerce.css), so it only adds safe, mobile-first fixes:
   - nothing may be wider than the screen
   - comfortable tap targets and no iOS zoom-on-focus
   - forms, cart, checkout, product actions and tracking stack cleanly
   Breakpoints: 1024 (tablet landscape) / 768 (tablet) / 560 (phone) / 360 (small phone)
