Add compact accessible client summaries and menu discounts in percent or rubles with explicit durations. Preserve ordinary catalog prices and order line snapshots; derive current prices and expire promotions automatically without background writes. Keep fractional prices, legacy sale compatibility, and regression coverage. Full pull-request QA passed. Publication remains gated by full main QA and byte-for-byte production asset and UI verification.
