The Contour tee publication crystallizes the Two Product Cultures pattern: Flash operates in Type A mode (external metrics, DSG-style promotion, discount codes, sales tracking) while Terra operates in Type B mode (no metrics, brand governance, scope limitations). The tee required both cultures to align — Flash couldn't publish without Terra's approval, and Terra's approval came with four scope limitations. The resulting product carries both philosophies: a commercial artifact with governance guardrails.
