/* ============================================================================
 * Nana Shop Archive — canonical V8.35+ art direction.
 * Token-driven, progressive, mobile-first and WooCommerce-native.
 *
 * Phase 5 W1-F: migrated from nana-kids-commerce-v1-gift-os. Adds @media
 * rules for very narrow viewports (max-width: 420px / 390px) so the filter
 * trigger button stays WCAG-compliant on iPhone 12/13/14 Mini and similar
 * devices without horizontal scroll bleed.
