This update adds Shopify 2048 variant support, integrates the Shopify account menu, and includes several RTL and header fixes.

New features

• Support for Shopify's 2048 product variant limit — variant availability is now resolved server-side via the Section Rendering API, removing the inline variant JSON payload from the page
• Shopify account menu integration in the header secondary area
• Added new animation to Countdown timer

Fixes and other improvements

• Fix scroll jumping to top when clicking variant swatches or option labels
• Fix header menu disappearing on filter changes
• Fix minor header flicker
• RTL layout fixes
• Make sure select buttons are properly resized inside mobile menu

Performance improvements

• Eliminated forced reflows in header by consolidating four separate scroll listeners into one batched handler (reads before writes), reducing forced layouts per scroll tick from four to one
• Cached sticky header offset on resize instead of recalculating via getBoundingClientRect on every scroll event
• Moved announcement bar height calculation from scroll to resize listener
• Fixed forced reflow in product card image hover — mousemove handler now exits early when the hovered image slot hasn't changed, reducing DOM operations from O(n) per pixel to O(1)
• Replaced per-button click listeners on cart drawer remove buttons with a single delegated listener, eliminating listener re-attachment on every cart update
• Fixed ResizeObserver in scroll carousel using observer entry size instead of reading offsetLeft from DOM nodes
• Deferred scroll carousel arrow centering to requestAnimationFrame to avoid layout reads during element connection
• Deferred full menu height calculation to requestAnimationFrame
• Batched all reads before writes in submenu overflow detection to eliminate layout thrashing
• Fixed priority images (e.g. Shop Our Range section) bypassing lazy loading — high-priority images now use native srcset and loading="eager" so the browser preload scanner can fetch them immediately, resolving the "Request is discoverable in initial document" DevTools warning
• Fixed memory leaks: added disconnectedCallback cleanup to CartDrawer, CollapsibleRow, and ThemeHeader
• Fixed debounce utility arrow function preventing correct this binding at call sites
