Custom apparel customers design right on the product page

Challenge
AllStar Logo's old product designer was slow to load and froze while customers were designing, which cost the store a lot of customers. The site ran on PHP 7.3, so it could not even be updated.
Result
A 100 % page speed score across the whole website, PHP 8.5 and fully up to date, and customers finish their designs without the designer getting stuck.
