Cainiao tracking URL from a tracking number

Cainiao (CN) tracking numbers follow this format: LP prefix + 10-18 digits, or YANWEN prefix + alphanumeric (20-25 chars). ShipShim detects the carrier from the number and returns the direct tracking link.

Example: number in, tracking URL out

Example tracking numberLP8888888888
Tracking URLhttps://global.cainiao.com/detail.htm?mailNoList=LP8888888888

This format is distinctive, so ShipShim identifies Cainiao from the bare number — no hints needed.
