StackLens: Discount Monitor

Review Shopify discount definitions from a read-only dashboard. StackLens highlights overlapping campaign windows, combination-setting signals, upcoming starts and expirations, reported code-usage limits, and automatic-discount capacity. Each finding shows observed evidence and limitations. It doesn't edit discounts or predict which discount will apply to a cart. Longer history, compatible complete-scan comparisons, formula-safe CSV, lifecycle thresholds, and weekly scans are available.
