"""Flow service client for TBFF revenue routing.
After a swag sale, the margin (sale price minus POD fulfillment cost)
gets deposited into a TBFF funnel via the flow-service. The flow-service
manages threshold-based distribution, and when the funnel overflows its
MAX threshold, excess funds route to the bonding curve.
Revenue split flow:
Mollie payment → calculate margin → deposit to flow-service funnel
TBFF thresholds
↓ overflow
bonding curve ($MYCO)
