SKU-Reconciled Fulfillment Safe Picks

Final-gate promotion collection. Products belong here only after active status, approved vendor, positive inventory, complete variant SKUs, and SKU-to-fulfillment reconciliation pass. Printify products must use complete Printify-style variant SKUs; CJ products must use CJ-prefixed variant SKUs. Anything unmapped, duplicated, mixed-vendor, missing SKU, or unclear should stay out of this collection until manually reconciled.
