Added

• OverlayManager for centralized panel/drawer management — stack-based open/close, ESC key support, and before-close hooks
• <cart-remove> custom element for cart item removal, works in both cart drawer and main cart page
• Collection tabs AJAX loading — inactive tabs load products on demand with client-side caching and request deduplication
• <quick-navigation> custom element that closes on click outside and ESC key
• Deferred mobile menu sub-menus using <template> elements, cloned into DOM on first interaction
• Hindi, Japanese, and Brazilian Portuguese locale files
• disconnectedCallback on 7 custom elements for theme editor memory leak prevention
• <inventory-notice> custom element with animated inventory bar that transitions smoothly on variant change

Changed

• Predictive search: LRU cache (50 entries), AbortController, event delegation, and proper error handling
• Quick-view: client-side cache, AbortController, and improved script reloading
• Announcement bar and breadcrumbs CSS inlined via {% style %} blocks, remaining CSS loaded async
• First product image in collections uses fetchpriority="high" with eager loading
• Shop-our-range priority images restricted to section.index == 1 (~583 KiB savings)
• Responsive image: priority images always use full-resolution src, support defer parameter
• Inventory bar uses CSS transition instead of keyframe animation so it animates between values on variant change instead of restarting from full width
• Sticky scroller refactored — DOM reads moved to connectedCallback, header height updates separated from content recalculations, listens to product:variant-change for content updates
• Head variables optimized — removed unused variables, inlined single-use variables
• Cart popup excluded from OverlayManager (small popup, not a side panel)
• Background video section deferred with <template> element — iframes and Shopify-hosted videos are inert until IntersectionObserver stamps them into the DOM near the viewport

Removed

• All no-js and no-js-hidden references from Liquid and SCSS (21 files)

Other fixes and improvements

• Fixed JSHint warning in shop-our-range.js
• Fixed oldScrollPositon typo in sticky-scroller.js
• Fixed quick-view canceled requests in product recommendations — added stopPropagation to prevent click bubbling to parent links, clear controller after success, always remove loading class on abort
• Fixed sticky-scroller jank caused by ResizeObserver feedback loop with class toggles
