Government Procurement Consolidation Optimizer — Discount Tiers & Holding Cost (2D)

This 2D companion to the 3D procurement-consolidation simulator keeps the exact same economics — the same discount-tier thresholds, the same holding-cost accrual, the same random agency request arrivals — but lays it out as a flat, draggable network diagram plus two dedicated readouts a free-orbiting 3D scene can't show at a glance: a vertical tier bar with the volume-discount thresholds marked directly on it, and a history strip recording the net savings of every batch shipped so far, colored by the tier it settled at. Drag the ring of agency nodes to spin the view (the same free-look interaction OrbitControls gives the 3D scene), tune the consolidation window and demand intensity, and watch how a longer wait usually buys a richer discount tier until holding cost starts eating the gain.
