Friction ‑ Guest Cart Restore

Guest shoppers can add products, leave, & return later to an empty cart. Anonymous carts rely on browser storage, so they can disappear 7-30 days from cart creation, depending on browser or device. Friction saves eligible guest cart contents server-side & restores them when the same shopper returns. This helps merchants keep purchase intent alive, give shoppers a smoother path to checkout, and recover potential revenue from carts that may otherwise be lost. No code edits or storefront changes.
