Sign Customiser has improved the reliability of logo uploads and SVG conversions across all browsers. Safari users in particular will benefit from better memory management and smoother handling when switching between tabs or returning to the customiser after the browser has been in the background.

## What’s Changed

- **Cross-browser SVG compatibility**SVG elements are now correctly rendered in Firefox and Safari, fixing an issue where path length calculations could fail on detached elements
- **Safari memory management**Logo uploads now use less memory on Safari by cleaning up image previews and file data after processing completes
- **Reliable polling after tab switching**Returning to the customiser after Safari puts the page to sleep no longer stalls the logo conversion progress
- **Eliminated duplicate processing**Fixed an issue where the logo upload status could trigger multiple conversion checks simultaneously, improving reliability and reducing unnecessary network requests
- **Preserved logo data for cart**Logo URLs are now correctly retained through to checkout, preventing missing logo references when adding to cart
