Concurrency automation templates

Checks 200 shipment tracking numbers on a public carrier tracker using eight parallel workers pulling from a shared in-memory queue. Reads the tracking list straight from the carrier's bulk page, scrapes status, latest event and ETA for each shipment, and writes a full status CSV plus an exceptions-only CSV covering customs holds, failed deliveries and delays. No login required.

Verifies insurance for every appointment on a clinic's eligibility worklist, running the payer checks on nine parallel browsers instead of one at a time. Signs in, reads the worklist, fans out into workers that each claim an appointment from a shared queue, click its eligibility check and read the coverage answer. Writes a full status CSV plus a coverage-problems CSV listing the lapsed and not-covered patients the front desk has to chase.

Demonstrates parallel browser automation using Fork Branch and Memory Queue. Creates multiple concurrent browser instances that dequeue items from a shared queue, navigate to e-commerce websites, and take screenshots simultaneously.
