Loaded by sections/navigation.liquid.\n   Styles: theme-styles.scss.liquid (Nov 2026 block, \"Header menus on computers: keyboard\").\n\n   Before, the Jewelry and Accessories menus opened only on mouse hover, and the\n   Tab key jumped from JEWELRY straight to ACCESSORIES, skipping every link inside.\n   Now:\n   - Tab onto a menu heading opens its menu; Tab and Shift+Tab move through its\n     links, and leaving the menu closes it.\n   - Down arrow on a heading opens its menu and moves to its first link.\n   - Esc closes the open menu and puts the focus back on its heading, so the next\n     Tab goes on to the next heading.\n   - Screen readers hear whether each menu is open (aria-expanded).\n   Menus open on focus only when the focus comes from the keyboard, so a mouse\n   click never leaves a menu stuck open. Phones and tablets (under 1200px) keep\n   the theme's own slide-in menu.\n   ========================================================================== */\n(function () {\n  var nav = document.querySelector('.wrapper-navigation .site-nav');\n  if (!nav || !window.matchMedia) return;\n  var desktop = window.matchMedia('(min-width: 1200px)');\n\n  // Headings with a menu: the top row, plus second-level items of simple (non-mega)\n  // dropdowns, which open sideways.
