Added crawler-facing direct search data, public indexed product-identity recovery, and bounded rotation across up to eight fresh residential listing sessions so intermittent empty client shells no longer fail after one residential route.
Prevented non-purchasable zero-price card fragments from appearing as current seller-catalog prices; unavailable prices are now null.
Clarified that item snapshots always preserve core identity while deeper structured fields depend on what AliExpress exposes.
Added AliExpress keyword search extraction with prices, ratings, sales counts, images, and canonical product URLs.
Added product-detail extraction for stock, variants, specifications, and public seller information, with a rendered-page fallback for useful core fields when structured data is unavailable.
Added public seller-catalog extraction for supplier assortment snapshots.
Added bounded sticky datacenter session rotation for AliExpress challenge and empty-shell responses, without an automatic residential fallback.
