/*!
 * MSIIA mobile header + navigation panel — v3 (2026-07-20)
 * =====================================================================
 * v3 changes vs v2:
 *   - Removed the standalone `.mobile-account-btn` circle entirely
 *     (previously injected into every page; produced an orphaned user
 *     icon between the brand and the hamburger).
 *   - The mobile header now renders four controls in this order:
 *
 *         BRAND · CART · ACCOUNT · MENU
 *
 *     Cart = `.header-cart-btn` (icon + count badge + optional caret).
 *     Account = `.account-nav-group > .nav-link.nav-dropdown-toggle`
 *     (icon-only trigger for the existing account dropdown).
 *   - Cart + account controls are shown INSIDE the closed row (no
 *     display:none hack); they are re-styled at ≤768px to a 40 px
 *     glass square that matches the mobile-toggle so all three read
 *     as one control family.
 *
 * Direction: institutional luxury / futuristic trading terminal.
 *   - premium glassmorphism panel with 22 px blur + saturation lift
 *   - fine gold laser line along the top border
 *   - soft radial fog near the panel bottom for atmospheric depth
 *   - travelling gloss sheen on the primary CTA
 *   - subtle inset highlights on every interactive glass surface
 *   - 40 px control height, 44 px minimum touch target, 60–68 px header
 *
 * All effects respect prefers-reduced-motion.
