Use the weekly-performance-analyst Skill.

Prepare Monday's trading review from the sales, acquisition and stock exports. Explain revenue, conversion and average-order-value changes, identify winning and declining SKUs, separate acquisition performance from returning customers, and flag stockout and overstock risks. End with today's highest-priority action, two actions for the week and one monthly initiative.

The attached business materials are:
- inputs/brief.json
- inputs/products.csv
- inputs/traffic.json

Deliver a complete result.md report that the operations team can read, plus any finished files needed for this task. Keep supporting calculations and evidence with the deliverables. Write the report in English; use the requested target language for customer-facing copy. The business datasets are fictional examples unless the brief explicitly names a live public website.
