/* ==========================================================================
   Gulf Publications — Responsive Styles & Mobile Navigation
   --------------------------------------------------------------------------
   This file holds EVERY @media query for the site, plus the mobile
   slide-out drawer navigation. Load it immediately AFTER style.css:

       <link rel="stylesheet" href="assets/css/style.css" />
       <link rel="stylesheet" href="assets/css/responsive.css" />

   style.css keeps the base styles, colours, design tokens, components and
   desktop layouts. Desktop rendering is the exact union of style.css +
   this file and is unchanged from the original single-stylesheet build —
   the min-width blocks that shape the desktop grid were simply relocated
   here so every media query lives in one place.
